Hirokazu Miura, Masahiro Hakoda, Noriyuki Matsuda, Hirokazu Taki

KNOWLEDGE-BASED AND INTELLIGENT INFORMATION & ENGINEERING SYSTEMS (KES 2019) ( ELSEVIER ) 159 2224 - 2231 2019年 [査読有り]

Human beings perform various motion ranging from simple motion to advanced motion. In addition, sensory information is used as a feedback information of the motion state during operations which require fine adjustment. It is necessary for performing advanced motion to acquire the corresponding skills. To learn such skills efficiently, it is necessary to construct a skill learning system. Grasping skill acquisition status is effective for the skill learning system. Currently, there is no other method than evaluating skill acquisition status by using learners' task scores. However, this method may not be enough to evaluate skill acquisition status. On the other hand, brain has the function of motion commands and sensory acceptance when moving the body. Therefore, it might be possible to sufficiently evaluate skill acquisition status by using the changes of brain activity. In the paper, we measured the changes of cerebral blood flow on learning of force adjustment skill. The obtained data was analyzed by principal component analysis (PCA) and Recurrent Neural Network (RNN). The result of PCA shows that there are some channels which have the changes of the principal component score before and after learning. In the classification by RNN, when the first principal component scores of the cerebral blood flow data before and after learning were used for input data, high classification accuracy was obtained. In addition, higher classification accuracy was obtained when using only channels which have changes in the principal component scores before and after the learning are used as input data, rather than all channels were inputted. From these results, it is shown that characteristics of the prefrontal cerebral blood flow changes according to the motor skill learning. (C) 2019 The Authors. Published by Elsevier B.V.

Distance recognition is the skill to estimate the distance to the target object. Such a distance recognition skill is one of the most important skills in everyday life. In various situations, such as walking, driving a car, communicating with people and so on, humans perceive the distance between the targets, and do the adequate action. Generally, the precision of distance recognition is different according to difference of the ambient surroundings, the objects, and especially the individual's ability. The distance recognition is achieved by capturing the target object visually and processing its visual information in their brains. Therefore, it is important to investigate how the difference of distance recognition skills affects the brain activity. In the paper, we measure the cerebral blood flow as a brain activity by using NIRS (Near-Infrared Spectroscopy) in the distance recognition. 2018 The Authors. Published by Elsevier Ltd.

Therefore, it might be possible to sufficiently evaluate skill acquisition status by using the changes of brain activity.In the paper, we measured the changes of EEG accompanying learning on force adjustment skill. The obtained EEG data was filtered to remove some noise using Band-pass filter, and then it was transformed into a frequency component by FFT, and the ratio of alpha wave and beta wave was calculated in the EEG data. In addition, we computed EEG coherence between the electrodes of near the frontal association cortex and the electrodes of near the primary motor cortex, between electrodes of near the frontal association cortex and electrodes of primary somatosensory cortex. As a result, the characteristics of the skill acquisition stage could be confirmed from the change of the ratio of alpha wave and beta wave, increase and decrease of the coherence values.

In recent years, measurement techniques and devices of cerebral function and brain activity have been improved. Therefore, "Neuromarketing" has been attracting attention. Neuromarketing is one of commercial activities and is in the marketing researches which study comsumers' response to purchase activity. Neuromarketing is helpful for companies to elucidate principles of actions unconsciously caused by human and has 2 purposes to increase effectively consumers' eagerness to buy. First purpose is elucidating what consumers bought for indexes at the time of purchasing decision making. Second purpose is elucidating what consumers regard as important in the indexes. fMRI is used mainly for such a brain activity measurement. However, there are several problems to use fMRI, which has limitation on the posture of the subject is very expensive. Therefore, it is expected that a portable NIRS (Near-infrared spectroscopy) brain measuring apparatus may be suitable for a study of neuromarketing. We investigate the relation between impressions of the product brand and consumers' brain response. From our investigation, we show that different brand impression results in different effect on the cerebral blood flow by a portable NIRS brain measuring apparatus. (C) 2016 The Authors.

We proposed operating HMD by BMI to speed up operation and to enhance the convenience in wearable device equipping HMD. But it is difficult to reflect user's thought direct on operation at this stage. In order to realize it, we need to identify a kind of human's brain signal when human thinks about moving object. So our study verifies whether it is possible to identify by imaging direction in data that we investigate cerebral blood flow changes in using NIRS when subject thinks about moving object. Identification was using neural network. The average of identification ratio of 4 direction in Total-Hb, the average of identification ratio of 4 direction in Oxy-Hb, the average of identification ratio of 4 direction in Deoxy-Hb are 32.25%, 36.0% and 37.0%, respectively. The average of identification ratio of 2 direction, up and down, in Total-Hb, the average of identification ratio of 2 direction, up and down, in Oxy-Hb, the average of identification ratio of 2 direction, up and down, in Deoxy-Hb are 63.5%, 62.0% and 62.5%, respectively. The average of identification ratio of 2 direction, left and right, in Total-Hb, the average of identification ratio of 2 direction, left and right, in Oxy-Hb, the average of identification ratio of 2 direction, left and right, in Deoxy-Hb are 58.0%, 55.5% and 69.0%, respectively. From the results, we show the possibility of identification because identification ratio are higher than chance level. (C) 2016 The Authors. Published by Elsevier B.V.

Analysis of Multiple-Choice Tests Through Erroneous Choices Using a Technique of Automatic Problem Generation.

Noriyuki Matsuda, Hisashi Ogawa, Tsukasa Hirashima, Hirokazu Taki (担当区分：筆頭著者 )

In: Yamamoto S. (eds) Human Interface and the Management of Information. Information and Knowledge in Context. HIMI 2015. Lecture Notes in Computer Science ( Springer ) 9173 362 - 369 2015年07月 [査読有り]

In multiple-choice problems, incorrect choices that hide correct answer do not play the only significant function. A more significant function is to capture learner errors and provide learners with the opportunity to amend those errors. In this sense, explanation texts for incorrect choices might be important in allowing learners to amend their own errors correctly. In this paper, we term this “meaningful erroneous choice.” We confirm the existence of meaningful erroneous choice through actual problems used in an examination. We then compare choices using a technique of automatic problem generation. The result indicates that the difference between correctness knowledge and incorrectness knowledge plays an important role in problem posing.

KNOWLEDGE-BASED AND INTELLIGENT INFORMATION & ENGINEERING SYSTEMS 19TH ANNUAL CONFERENCE, KES-2015 ( ELSEVIER SCIENCE BV ) 60 1233 - 1239 2015年 [査読有り]

In recent years, Brain-Machine Interface (BMI) has been improved with the rapid development of the cerebral function measurement technologies. BMI is used for measuring the brain activity of the subjects and inferring his/her intention. These measuring results can control the devices such as the electric wheelchair or the electric arm directly. Previous studies have such problems that BMI device is not portable, and it takes much time to attach a lot of sensor nodes on the head of the subject. Therefore, we use portable NIRS, because it is easy for the subjects to mount it and their burden is low. This paper describes the analytical method for cerebral blood flow during imagining affirmative or negative answers to the questions. It was verified whether it is possible to use the NIRS as BMI to discriminate the yes answer or no without voice and gesture. In our study, a subject keeps watching the display which shows a yes-no question, he/she imagines affirmative or negative answer to the questions. In the experiment, one test trial is in 30 seconds and it includes 10 seconds task between 10 seconds rests. Each test set consists of 10 trials. One subject has five test set. In our study, we used Wearable Optical Topography WOT-100 as measurement device of NIRS which has 10 channels (ch7-16) of prefrontal cortex. The NIRS data analysis procedure is as follows; in the first step, we used a band-pass filter to select the data of frequencies from 0.02Hz up to 0.1Hz. In the second step, measured NIRS data of each task set is divided into 10 blocks which are included 5 seconds data before the task and 10 seconds data after the task. In the third step, we calculated baseline of measured data from 5 seconds of the beginning and the end of the task blocks, and this baseline fitting is applied to the original data. In the last step, the neural network learned the important elements of the training data and classified the test data. Our method can discriminate between imagining affirmative or negative answers with 70% accuracy. At result, NIRS is useful to discriminate the yes-no answer of the questions. (C) 2015 The Authors.

A generating technique and knowledge representation of multiple-answer problems for learning with solving knowledge.

Noriyuki Matsuda, Hisashi Ogawa, Tsukasa Hirashima, Hirokazu Taki (担当区分：筆頭著者 )

Res. Pract. Technol. Enhanc. Learn. ( Springer ) 10 ( 1 ) 6 - 6 2015年 [査読有り]

Background
Erroneous answers in multiple-answer problems not only make the correct answer harder to determine but also indicate why the correct choice is suitable and the erroneous one a mistake when compared to the correct answer. However, it is insufficient to simply create erroneous answers for this purpose: explanations of these answers are also required. Preexisting studies examining functions for generating erroneous answers and their explanations based on this approach are abundant. Nevertheless, a major bottleneck has formed in this research body concerning the related specialized knowledge descriptions that are required for the generation function.

Methods
This paper focuses on the notion that it is easy for teachers skilled in problem solving to express specific problems in written form and amend incomplete knowledge. Furthermore, it examines a method of constructing knowledge while generating and updating knowledge from specific problems.

Result and Conclusion
The suitability of the proposed method was verified by examining actual knowledge constructed by the research subjects.

In recent years, it is difficult to inherit high level sensory skill, because the number of experts is not so much or the experts are too busy to teach their skill to the beginners. Therefore, many learners do the experiential learning through visual and haptic digital teaching materials. In such a system, however, it is difficult to evaluate whether the learner could recognize the sensation and obtain the sensory skill. In the paper, we investigate whether the biological signal such as EEG can be used for the evaluation of the haptic task skill level. (C) 2014 Published by Elsevier B.V.

This paper describes the method for classification of brain state by the measured electroencephalogram (EEG) frequency in directions (up, down, left, and right) imagination. Recently, Brain-Machine Interface (BMI) has been studied in a variety of ways due to the development of brain measurement technology. Therefore, we have used the BMI to identify the human selection of directions. Our method consists of data normalization, principal component analysis and neural network. The maximum value of the identification rate was 46% by using 3 electrodes (F4, F8 and T8) in the previous study. In this study, we improved the learning method of neural network for the improvement of identification rate of brain state. For that purpose, the measurement points of EEG and the number of subjects are increased. As a result, the maximum value of the identification rate was improved. (C) 2014 Published by Elsevier B.V.

The Problem Oriented System (POS), SOAP, and Focus Charting are popular methods of recording nursing activities as a way to improve collaborative nursing practices. However, explicit training methods for what and how nurses should write these recording systems for their nursing have not been sufficiently established. In regard to such trainings, we consider that a tutor's thinking process is more important than the actual thinking result (e.g., a comment document). Our approach is to express tutor's intention of teaching as a map in order to develop an educational tool that can be used in trainings on what and how to think in recording their activities. This paper presents an overview of the reviewing tool we developed, which provides tags as criteria of a tutor's judgment. We have confirmed that, at least, the proposed method does not hinder a tutor's review of a nurse's case writing.

We think that to acquire a skill for co-creating knowledge with others cooperatively, it is important to develop meta-cognitive skill, but to do so is not straightforward. In this paper, we attempt to design a thinking skill (particularly meta-cognitive skill) development curriculum for first-year bachelor-degree students on the basis of the results obtained in two preceding studies that we have performed for postgraduate education and those engaged in medical services. To deal effectively with new learning for first-year bachelor students – ‘thinking about thinking’ – we designed a curriculum that gives students a knowledge co-creation programme and thinking externalisation tool to devote attention to the thinking process and to have the bodily sensation of its meaning, and we put it into practice. This paper describes a learning model for thinking skill, which is fundamental to appropriate curriculum design, and discusses the design intention of a curriculum conforming to it and the usefulness of the learning programme through examples of using the thinking externalisation tool in practice. Results show that the learning programme developed in this study is useful for cultivating the meta-cognitive skill of bachelor students.

The authors hold the opinion that to acquire a skill for co-creating knowledge with others cooperatively, development of meta-cognitive skill is important, but to do so is not straightforward. Herein, we attempt to design thinking skill (particularly meta-cognitive skill) development curriculum for first year bachelor students based on the results obtained by two preceding studies we have performed so far for postgraduate education and those engaged with medical services. To deal effectively with new learning for first year bachelor students—“Thinking about thinking”—we designed a curriculum by which students are given knowledge co-creation program and thinking externally tool to devote attention to thinking process and to have bodily sensation of its meaning, and put it into practice. This paper describes learning model for thinking skill which is fundamental to appropriate curriculum designing and discusses design rationale of the curriculum conforming to it and usefulness of the learning program through examples of practice using thinking externally tool. Results show that the learning program developed in this study is useful for cultivating meta-cognitive skill of bachelor students.

Prologによる解法知識を用いた誤答解説文付き多肢選択問題の生成

小川修史, 松田憲幸, 平嶋宗, 瀧寛和

教育システム情報学会誌 ( 教育システム情報学会 ) 30 ( 2 ) 139 - 147 2013年 [査読有り]

In this paper, we describe the concept of Simulation of Erroneous Solution (SES) to generate an adequate number of distractors and the erroneous solution in multiple-choice questions. SES is a method of generating a solution from wrong knowledge to wrong answer, by a perturbation from problem-solving knowledge to knowledge of wrong answer derivation. The perturbation is projected on a student's typical error, and the perturbation operator expresses the difference between the erroneous solution and the correct solution. We confirmed that forty eight questions and a hundred twenty eight explanation text about the distractors are automatically generated from seventeen Prolog clauses as knowledge into SES, and the SES has the potential for generating relevant distractors and the erroneous solution.

In late years, the ITS which aims at improvement of convenience and the comfort in the road traffic using an information technology attracts attention, and service to deliver useful information quickly by communication among vehicles is flourishing research area. However, vehicles may be distributed sparsely by traffic conditions in VANET, and it is difficult to maintain stability of the communication. Therefore, DTN technology that communication is enabled by permitting a delay even if vehicles are distributed sparsely can be applied in such an environment. However, a delay occurs for the delivery of data when I apply DTN environment. Therefore, it becomes difficult to deliver a reply message to the requesting vehicle due to movement of the vehicle before message arrival. For such a problem, we aim at the arrival rate improvement of the reply message by while the requesting vehicle waits for a reply, advertising the own position on neighboring appropriate vehicles. Then, we evaluated our method which distribute an advertisement to vehicles nearby and suggested the method using the flooding and the method using geocast. We investigated that an arrival rate of the reply message is improved by our proposed method by computer simulation.

We study about a method to describe knowledge for generating an adequate number of multiple-choice questions. We focus on the fact that instructors can easily explain concrete multiple-choice questions, even if they cannot describe the domain knowledge completely. We propose the Environment of Abstract Rule (EAR), which enables an instructor to describe abstract knowledge by explaining the difference among some concrete multiple-choice questions, and by representing the knowledge in the form of a diagram. In this paper, we describe the concept of EAR and report the results of a preliminary experiment in which we explored whether instructors could describe knowledge easily. As a result, we suggest that the EAR has the potential for generating appropriate knowledge.

<p>This paper describes a method to recognize and learn a character handwritten in the air. This recognition method uses the motion direction instead of positions of the device. It also doesn't use the information of pen up and down. It selects and orders character candidates with DP (dynamic programming) matching. To use this matching, at first, we analyzed standard character shapes and made penalty codes and dictionary. However, the recognition rates was not stable. Therefore, we adopted Genetic Algorithm in order to define those parameters. As a result, we get general penalty codes which doesn't depend on users and dictionary. And we improve recognition rates of bad operator by learned dictionary. But recognition rates with evaluation data by learned dictionary is not so effective compare with learned penalty codes.</p>

A Technique for Error Awareness in Pencil Drawing

Noriyuki MATSUDA, Tsukasa HIRASHIMA, Tomoya HORIGUCHI, Hirokazu TAKI (担当区分：筆頭著者 )

S. L. Wong et al. (Eds.) (2010). Proceedings of the 18th International Conference on Computers in Education ( Asia-Pacific Society for Computers in Education ) 275 - 279 2010年04月 [査読有り]

Training in realistic drawing is a basic technique of art education. Even though a novice artist may feel something is wrong in his or her sketch, the novice often cannot explain what the errors are. It is typical for a drawing teacher to try to advise a student about errors during drawing training by using analogical explanation. Analogical explanation provides the learner with an image of a solid that reflects his or her errors. However, the significance or merit of this kind of explanation is not well understood, even though the importance of learning by error is well known in practical education conditions. This paper describes a technique for error awareness in pencil drawing. The technique involves the creation of a three-dimensional model that reflects the learner's errors as acquired from a scanned digital image of the learner's pencil drawing.

Real time interpolation of haptic information using case base

Takayuki Toki, Hirokazu Taki, Hirokazu Miura, Noriyuki Matsuda, Masato Soga, Norihiro Abe

Proceedings of the 15th International Symposium on Artificial Life and Robotics, AROB 15th'10 1006 - 1009 2010年

This paper has described a real time interpolation technology for haptic information using case base. To share haptic data in multiple points, we must send complete haptic data. However, in the transmission line, packet loss and noise are occurred sometimes. In this situation, users don't sense correct force. We developed new interpolation method for haptic sense data without conventional mathematical approach. We can interpolate haptic information lag and loss using case-based approach. In our method, the system selects a suitable case and reconfigures it to fit the error. © 2010 ISAROB.

初心者のための鉛筆デッサンの基礎は，対象を見えたまま正確に描きとる写実であり，獲得が難しい技能である．初心者は自己の写実の誤りに気づくことができない，あるいはデッサン画全体に漠然とした違和感を感じることができても，具体的に写実の何が誤りかを判断できず，同じ誤りを繰り返す．反復練習を指導する教師は，写実の誤りを理解させるため，描く対象と異なった立体物をイメージさせるたとえ（比喩）を用いる．学習者は比喩説明を聞く過程で徐々に，明らかに異なるイメージの写実と感じるようになり，ついに自己の写実の誤りに気づくと考えられる．本論文は学習者の鉛筆デッサン画像に含まれる写実の誤りを顕在化した三次元モデルを構築する手法を検討する．本手法は誤った写実による1 枚の画像から，誤りを映し出し，かつ直感的に不自然さを感じさせる三次元モデルを構築する．写実の8 種の誤りを対象に，デッサン画像の誤りを特徴づける15個の特徴量を用いて三次元モデルのスケーリング変換を定義した．三次元モデルを表示する顕在化ツールを実装した．学習者が本ツールを用いることで，鉛筆デッサンに含まれる写実の誤りに気づきやすくなると期待できる．本研究の一部は文部科学省科学研究補助金基盤研究（B）（2）（課題番号：163000369）による．

This paper describes the on-line handwritten character recognition method in an arbitrary place without the information of up and down moving of the pen lifting. This method can be applied to the character interface (aerial handwritten character recognition device) with which the user moves the hand in the air. To realize the system, we selected the gyro sensor for the aerial handwritten character recognition device. This device can detect the moving direction. The advantage of this device is able to be used anytime and anywhere like a pen. It is not necessary to preparer the table in order to detect absolute position. We developed the blackboard model recognition system that includes 2 types DP matching recognition programs. The system is able to recognize the Japanese hiragana characters in 84% accuracy.

Japan suffers from a high number of earthquakes, so the technology for an earthquake observation is highly demanded. One of information on an earthquake is seismic intensity information which is measured with seismic intensity meters and is announced by the media such as TV. The seismic intensity is a value observed at a location where a seismic intensity meter is placed. This means that the seismic intensity shows wide area information such as administrative districts, e.g., city, town or village. However sites where equal seismic intensity was observed would not necessarily suffer the same damage, because damage depends on the type of construction and on the nature of the seismic motion. Therefore, it is difficult to estimate the individual damage in personal area. In order to measure all the locations, it is necessary to place huge number of seismic intensity meters. In the paper, we develop the system which can observe an earthquake by using wireless sensor network technology. We use wireless nodes equipped with acceleration sensors. The system can provide useful information to predict the individual damage.

Skill, such as arts, sports and crafts, is regarded as a cycle that consists of the following three steps: recognition of objects, selection of appropriate action series and execution of the action. In arts and crafts, people produce works as a result of this cycle. Skill-learning environment should involve diagnosis-function providing appropriate advice for each step. This paper describes technique that is providing advice in real time when a learner learns recognition of drawing. To assist learners' recognition, we developed the sketch-area-dependent advising system that presents advice with voice for learners' drawing. The effectiveness of advice was confirmed through an experiment evaluating proposed technique.

We developed an arm motion animation system that can show learner’s arm motion on real time with magnetic position sensors. The learner can see his/her arm motion from any point of view with the system. We applied the system to sketch learning environment. We developed a sketch learning support system that diagnoses learner’s arm motion and advises adaptively.
Sketch drawing is a skill. It is important to diagnose not only completed work but also recognition, motion, and selection of action. The system in this paper is regarded as a motion diagnosis system.

Skill knowledge is important human knowledge as well as symbolic knowledge. Definition of skill knowledge is knowledge on high level technique that human acquire through repeated training. Skill knowledge is needed for arts, sports and crafts. It concerns human body structure, muscles, and joints. Also, skill knowledge concerns process of human interaction with objects, namely, recognition and action. There are many researches on learning support system for describable knowledge, such as mathematics, physics, grammar, etc. However, there is few pieces of research on learning support system for skill such as arts and sports. This paper analyses skills and generalize skill features. Then we describe problems to diagnose skill errors. After that, we introduce a learning support system for sketch as an example of a skill learning support environment.

Context-aware computing that recognizes the context in which a user performs a task is one of the most important techniques for supporting user activity in ubiquitous computing. To realize context-aware computing, a computer needs to recognize the user's location. This paper describes a technique for location detection inside a room using radio waves from a user's computer. The proposed technique has to be sufficiently robust to cater for dynamic environments and should require only ordinary network devices, such as radio signal emitters, without the need for special equipment. We propose performing localization by relative values of RSSI (Received Signal Strength Indicator) among wireless nodes, and also our system support the node mobility. We evaluate the performance of our system in the environment where the node is movable.

This paper describes the production of digital educational content which is reflected development stage of each autistic person. There are issues to model learner's developmental stage and to reflect it to the digital educational content. Therefore, we propose student model which consists of three acknowledgement skills (Language, Figure, and Matching) and correspondence rules which describes the relation between the student model and the digital educational content. Then, we developed the authoring system which consists of the student model and the correspondence rules. Instructors evaluated this system. Effectiveness of the system is turned out by the evaluation.

This research describes the analysis of a decision tree to interactively make rules from data that includes noise. A decision tree is often used in data mining technology because classification rules generated by the decision tree form new knowledge for the domain. However, it is difficult for a non-specialist user of data analysis to discover knowledge even if the decision tree is presented to the user. Moreover, the target data for raining may have both discrete values and continuous values, and these may include a lot of noise and exceptions. To understand the rules, the user needs the intermediate results of mining. Our system has interactive functions to realize interactive mining, and in this research, we propose a data mining technique with an interpretation function so that the user can understand analyzed data from which a required rule is derived.

"ROSAI" hospital, Wakayama City in Japan, reported that inpatient's bed-downfall is one of the most serious accidents in hospital at night. Many inpatients have been having serious damages from downfall accidents from a bed. To prevent accidents, the hospital tested several sensors in a sickroom to send warning-signal of inpatient's downfall accidents to a nurse. However, it sent too much inadequate wrong warning about inpatients' sleeping situation. To send a nurse useful information, precise automatic detection for an inpatient's sleeping situation is necessary. In this paper, we focus on a clustering-algorithm which evaluates inpatient's situation from multiple angles by several kinds of sensor including night-vision CCD camera. This paper indicates new relief algorithm to improve the weakness about exceptional cases.

This paper describes a classification criteria-structuring method for handling exception cases. Clustering technology is utilized to classify large amounts of data effectively. In current clustering technology, however, it is impossible for a system to classify all data completely, due to exceptions in the data. In an ubiquitous computing environment, exceptions arise due to changes in the environment. We propose an architecture in which the system changes classification criteria and rules using constructive induction.

We are developing a sketch learning support system that advises the way of modification to learners on their way in drawing a sketch. It is important to draw motif as it is when we draw a sketch. It is difficult for novice learners to grasp the form of motif or relation of position because they don't know the features they should focus on or take notice. Therefore, novice learners need some advice for sketch learning. We are developing sketch learning support system that advises the way of modification to learners on their way in drawing sketch. The advice system consists of area-dependent advice system and hand & arm motion advice system. Area-dependent advice system offers advice according to the way of drawing a figure when learners begin to draw the figure. Hand & arm motion advice system offers advice according to the way of moving hand & arms and modification method on their way in drawing sketch. We expect high learning effect with these real time advice systems.

In a lesson, a teacher requires to understand immediately the student their errors and give them adequate advice. As teaching training, teachers often visit an expert teacher’s class to observe the teaching and record the lesson by a video camera to analyze teaching skills. Although it is satisfactory to analyze the whole lesson, it takes much time to analyze and to search good advices in the long tape. Then, in this paper, the automatic method of dividing the record of the lesson is proposed so that it may refer to the specific advice directly. We developed a prototype system that records activities in the lesson and constructs a database for sharing among teachers. We confirmed the effectiveness of our system through the experiment.

This paper describes a medical knowledge and information retrieval system for general practitioners. Every year, the number of patients is increasing, but the general practitioners specialized in the lifestyle-related illness as diabetes are insufficient. The general practitioners are too busy to study bran new knowledge and information of their medical fields. Hence we have developed a medical information system, which has a semantic search function, was developed using a medical ontology that represents medical terminology semantic structure.

A picture is one of important research subjects in order to make our life spiritually rich. Most studies on pictures, however, only propose some substitute functions of actual drawing or painting materials. There is no system that evaluates pictures drawn by users and gives advice about them. We propose a learning support system for basic techniques in beginner's pencil drawing. The proposed system receives a subject (motif) data set and an image of user's sketch and returns advice to the user. The system is composed of the four subsystems: feature extraction of motifs, feature extraction of sketches, error identification, and generation and presentation of advice. We developed and experimented a prototype system limited to treat a basic motif and some principal advice. As a result, the validity of the proposed system was confirmed.

This paper proposes a filtering method on Web browsing. Some papers have reported that a user's interests shift continuously during browsing. To facilitate the user's browsing, a filtering system must adapt to the user's shift of interests. On the assumption that the user's interests are reflected in browsing page content and order, we have proposed Context-Sensitive Filtering (CSF) for a hypertext CD-ROM encyclopedia. In the encyclopedia, the entire hypertext is controlled to have one topic per page. We confirmed effectiveness of CSF for the encyclopedia. However, effectiveness of CSF for the Web was not confirmed. We inferred that the reason of failure is the difference in page properties of the Web and the encyclopedia. This paper describes modeling and CSF improvements. Main improvements include dividing a Web page to approximate an encyclopedia page and augmenting model calculation with TF-IDF. We confirmed effectiveness of proposed CSF through comparing several filtering methods.

We propose a method of information filtering for Web browsing based on a model of user's interests. We have already proposed Context-Sensitive Filtering (CSF) for browsing on CD-ROM encyclopedia, which follows up shifting user's interests in this case. We confirmed the effectiveness of CSF. However, it is not very effective for Web browsing. We assumed that one of the reasons is the difference of pages between the Web and CD-ROM encyclopedia. We describe improvements of modeling to estimate user's interests and filtering method by dividing Web pages. We confirmed the effectiveness of our filtering through an experiment to compare several filtering methods.

In a pencil drawing class, a teacher explains often the differences between a drawing and a motif by many ways; even so, it is difficult for most learners to understand the existence of errors in his/her drawing. When a learner watches the 3D model of his/her drawing from appropriate viewpoints, he/she is immediately aware of the errors. This paper describes the technique of error visualization from a learner's erroneous drawing. We developed a drawing advice system that consists of a 3D model converter from a 2D image and an evaluation function to estimate the effect of the 3D model. We designed a geometrical formula that expresses the relation between the geometrical feature and the error expression in the teacher's advice.

Browsing is one of the most popular ways to gather information in database with hypertext structure. In the brows-ing, a user continuously searches nodes which include use-ful information for her/him. Her/his interests, then, often change while the browsing. We call this type of brows-ing” context-sensitive browsing” in order to distinguish it from browsing with consistent interests. In this paper, we propose a method to filter the links in hypertext based on the user's browsing history. We assume that even when a user browses, following changeable interests without a clear task, the user’s current interests are reflected in the content and order of nodes in the browsing history. The filtering method models user's current interests from the user's browsing history and puts the next choices in or—der of the nearness to the interests. We call the filtering method" context-sensitive filtering”. We have developed a browsing support system with this method for an encyclopedia in CD-ROM format. The results of an experimental evaluation, by real users, are also reported.

プログラミングを行うためには,プログラムは少なくとも,プログラムの動作について明確に理解しておく必要がある.しかしながら初心者の場合プログラムの個々の命令の振舞いを理解できても,プログラム全体の動作を正しく理解できなかったり,プログラム仕様から動作を想定できない場合がよく見られる.このような初心者を対象とする場合,動作とプログラムコード,動作とプログラム仕様の対応関係について説明することが重要となる.本論文では動作の理解が特に難しい再帰プログラムを対象に,プログラムの動作を介したプログラミングを支援する知的教育システムについて述べる.筆者らは再帰プログラミングのモデルを想定した上で,学習者にとって理解が容易となるようにプログラムの動作を表現し,これをプログラムの振舞いと呼んでいる.本論文ではこの振舞い表現を用いて,再帰プログラムの設計過程および理解過程を支援する方法について論じる.特に,雛形を用いた解法による設計過程の支援ならびに,振舞い表現の可視化による理解過程の支援について述べる.更に振舞い表現の評価実験についても述べる.

This paper aims at designing an instructional system that teaches recursive programming to a novice programmer. In order to reduce a cognitive load which the novice bears in constructing algorithms in recursive programming, we propose the algorithm and solution for constructing the algorithm. The algorithm represents simple recursion as two iterations. We had an experiment to confirm if the instruction based on the solution is more effective than a programming textbook. As a result, the instruction had a significant effect. We have also designed an instructional system which helps the novice adaptively acquire the solution.
