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 an educational software for beginners in basic pencil drawing. Our system receives a subject (motif) data set and an image of a user's sketch and returns advice to the user. The processing is composed of the four functions: 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 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.

There is no system that evaluates pictures drawn by users and gives advice about them. We propose a learning support system of beginner's pencil drawing that is the basis of pictures. Our system receives a motif data set and a user's sketch image, and returns advice to the user.

Context-sensitive filtering for the web.

Noriyuki Matsuda, Tsukasa Hirashima, Toyohiro Nomoto, Hirokazu Taki, Jun'ichi Toyoda （Part： Lead author )

Web Intell. Agent Syst. 1 ( 3-4 ) 249 - 257 2003 [Refereed]

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.

International Conference on Computers in Education, 2002. Proceedings. ( IEEE Comput. Soc ) 1 193 - 194 2002.12 [Refereed]

To reuse an electronic educational material, a teacher has to understand its availability and methodology. This paper proposed the technique of integrating electronic class text, such as HTML/XML, into automated records of activities in a class. Our hypothesis is that an activity has influence on both the automated records and the class text. We designed structured record expression and event rules. The system integrates a class text into the records by forward deductive inference.

A Method of Information Filtering for Web Browsing Based on Dividing Web Pages

MATSUDA Noriyuki, NOMOTO Toyohiro, HIRASHIMA Tsukasa, TOYODA Junichi （Part： Lead author )

Transactions of the Institute of Systems, Control and Information Engineers ( THE INSTITUTE OF SYSTEMS, CONTROL AND INFORMATION ENGINEERS (ISCIE) ) 15 ( 4 ) 175 - 183 2002.04 [Refereed]

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.

The Proposal of the Technique of Error Visualization for a Learner's Pencil Drawing.

Nobuyuki Kajimoto, Noriyuki Matsuda, Hirokazu Taki, Masato Soga, Saeko Takagi, Fujiichi Yoshimoto, Takashi Shima

International Conference on Computers in Education, 2002. Proceedings. ( IEEE Comput. Soc ) 1 153 - 157 2002 [Refereed]

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.

Context-Sensitive Filtering for Hypertext Browsing

Noriyuki Matsuda, Toyohiro Nomoto （Part： Lead author )

Information Systems And Technologies For Network Society: Proceedings Of The Ipsj International Symposium ( World Scientific ) 253 1997.09 [Refereed]

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.

Toward Learning from Surfing

Toyohiro Nomoto, Noriyuki Matsuda, Tsukasa Hirashima, Jun'ichi Toyoda

Proceedings of the workshop "Intelligent Educational Systems on the World Wide Web", 8th World Conference of the AIED Society pp. 40-46 1997.08 [Refereed]

Browsing is one of the most popular ways to gather information in hypertext, for example, digital libraries or WWW. The surfing has a learning effect as its secondary one, although the purpose of the surfing is not learning. It is difficult to control the learning process from the educational viewpoint. However, the amount of knowledge gathered during browsing cannot be disregarded. Therefore, the way to support learning from browsing is an important issue in learning systems.
Usually, the browsing is carried out under a clear task. However, people often browse WWW or CD-ROM encyclopedia without a clear task. Such Browsing is called "surfing." In surfing, educational interruption may be allowed, because the purpose of surfing is only to surf. During surfing, user's interests often shift depending on the collected information, it is not haphazard one (so, we often call surfing "context-sensitive browsing"). As a first step to realize the support facilities for learning from surfing, we propose a filtering method to support surfing. In surfing, a user is often provided too many choices to reflect the collected information. In such situation, because user's cognitive load is heavy, learning from surfing is inefficient. In the filtering method, the shifting interests are modeled and the choices are ordered following the interests. The user may afford to learn from the collected information, because the load to find adequate information is reduced.
In this paper, we propose a filtering method for surfing. We have implemented it for CD-ROM encyclopedia. The results of experimental evaluation are reported in this paper.
