経典画像と既存のテキストファイルを対照表示させてテキスト部を編集可能とし，経典画像と同一内容のテキストファイルを効率良く作成することを目指して構築した，漢訳仏典翻刻支援システムについて述べる．本システムの特徴として，主にソフトウェア開発で用いられているバージョン管理ソフトウェアSubversionを導入し，テキストデータの履歴管理を行っている点，また編集を複数の作業者が同時に実施するための機能だけでなく，専門家がその差分表示を見比べて妥当なテキストを選定もしくは作成するための機能も実装した点があげられる．この分業体制を通じて，各参加者の小さな労力により，質の高い経典テキストデータの作成が期待できる．経典画像として金剛寺一切経撮影画像，既存テキストとして大正新脩大蔵経テキストデータを用いて評価実験を行い，有効性を確認した．We developed the support system of transcription for Chinese translated Buddhist sutras so that users can smoothly compose the text file. In this system, the version management software Subversion is introduced for maintaining the history of text files. In addition, we implemented not only the interface for rewriting by operators who look at a pair of shot image and editable text file, but that for choice or editing by an expert who can read the differential lines. Based on the division of labor, the system will be expected to produce text files which coincide with the shot images while the participants use their energy modestly. We conducted the experiments using shot images of Kongoji Issaikyo and the text data derived from Taisho Tripitaka to confirm the efficacy.

Bulletin of school of health and nursing science, Wakayama Medical University ( Wakayama Medical University ) 3 17 - 25 2007.03

The purpose of this study was that children in home medical care and their family could come to communicate with medical staffs at any time and lead a high quality of life in relief at home. We examined the medical needs of the patients and their family, and made medical information contents necessary for a system. On the basis of these contents, we constructed the system by using information technology (IT) for home-visiting nursing. We examined the utility and validity of this IT system by making a hearing investigation of the two pairs of patients' parents and the staff working for a home-visiting nursing station. As a result, we could hear their feelings that they were relieved because they could be taken care of by the medical staff at any time and they hoped to continue using this system in the future. In addition, it was suggested that the construction of this IT system was useful in responses to troubles and problems happening out of home-visiting time, and reinforcement of a heartwarming bond between medical staffs and parents-and-child in home medical care. We want to apply the system to other kinds of home medical care because the system can be operated in any area with few economic burdens.

Text Processing for Buddhist Canon Database

TANAKA Takehiko, NINO Yohei, NAKAGAWA Masaru

IPSJ SIG Notes ( Information Processing Society of Japan (IPSJ) ) 2006 ( 10 ) 33 - 40 2006.01

Text data are indispensable for retrieving the image among the digital archive of enormous files taken with digital cameras. We constructed a full-text search system of over 9,000 text files of Taisho Tripitaka, using Hyper Estraier as the search engine. To identify the text file, one can specify not only the phrases in a traditional way but the characters positioned hosizontally in a Buddhist canon written vertically. Another approach of the text processing is introduced, which helps the user to view the Buddhist canon images and the line-by-line corresponding text data at the same time.

A business method of consumer participated product planning for gift creation

HIRANO Takanori, TANAKA Takehiko, NAKAGAWA Masaru

IPSJ SIG Notes ( Information Processing Society of Japan (IPSJ) ) 2006 ( 9 ) 55 - 60 2006.01

We propose a new business method for electronic commerce that profits cost-cutting and advertising effect. The target of our method includes a small or medium sized enterprises short on staff, shopping malls that want to secure regular customers, and companies in service sectors that attempt to take a differential strategy. Based on the business method, we actually develop a prototype support system of gift creation. We implemented CMS modules which holds easy installation and high system generality.

Technical report of IEICE. KBSE ( The Institute of Electronics, Information and Communication Engineers ) 102 ( 603 ) 7 - 12 2003.01

About three years have passed since the introduction of public nursing care insurance, and the necessity for the operation supporting system has been increasing. In this paper, our developing system is explained which manages a database including the information required for the operations about elderly care insurance. The system should be ready for use anytime and anywhere. We have our system meet the need by introducing a personal digital assistant. The voice recognition and a tablet input are available for the inputting interface, and the user who has weak consciousness in a computer shall also use the system without feeling the resistance.

TANAKA Yasuyuki, TANAKA Takehiko, NAKAGAWA Masaru

Technical report of IEICE. KBSE ( The Institute of Electronics, Information and Communication Engineers ) 102 ( 603 ) 1 - 6 2003.01

We have been developing a Web application for diagnostic on-line questionnaires together with the question configuration and the score correction. The system returns a number calculated by the response to the questionnaire and by the weighting functions which are established by the questions and the answers. The feature of our system is that the weighting functions can be variable according to the response database. In other words, the result is always optimized by the reply data collected in the past. Moreover, we implement several supporting facilities, such as the creation of the questions, the configuration of the weighting functions, and the maintenance of the response database. Then the system is applied to a risk judging questionnaire of apoplexy in order to verify the validity of the correction technique of the weighting functions.

IPSJ SIG Notes ( Information Processing Society of Japan (IPSJ) ) 2002 ( 23 ) 41 - 48 2002.03

We develop a database system together with a prototype system that helps thinking of researchers of Japanese humanity. This system cannot only retrieve persons from several genealogy documents but also find a key person for given two persons and display the genealogies. These features will help researchers of humanity discover hidden human relationships. However it is complicated and difficult to store too many data about the persons and genealogies in the database. Then we produce the support system for smooth input.

Building an Electronic Shopping Mall Composed of Stores of the Same Trade

Hirano Takahiro, Nokami Akinori, Morikawa Hironobu, Tanaka Takehiko, Nakagawa Masaru

Proceeding of the Annual Conference Japan Society of Information and Knowledge ( Japan Society of Information and Knowledge ) ( 9 ) 55 - 58 2001.05

In recent years, electronic commercial transactions have been getting popular. We attend to develop an electronic shopping mall available to the Internaet. This shopping mall is constructed by a server computer for receiving the orders together with existing databases of the stores which are connected with the server computer. For giving fresh information of the goods to the purchasers, it is indispensable that the server computer and each trader's database frequently exchange messages. We also supply the methods which support the communication. Gathering traders of the same goods will lead to a commercial competition. As a result, purchasers will buy fine goods at a lower cost, while the sales dealer will make it easier to secure the new customers and repeaters.

Search and Management Technology for Large Number of 2D Images

Morikawa Hironobu, Imai Naoki, Nokami Akinori, Tanaka Takehiko, Nakagawa Masaru

Proceeding of the Annual Conference Japan Society of Information and Knowledge ( Japan Society of Information and Knowledge ) ( 8 ) 49 - 56 2000.05

We developed a system which enables users to register a large number of 2D images efficiently and to retrieve the image which matches his or her wish. In this system, the user can register, modify and delete the image data together with attributes through a Web browser, since CGI programs which the Web server executes access the image database. An experimental result shows that this method reduced the registration time to about l/7 against the traditional way of user's inputting SQL sentences. For image retrieval, we attempted to construct the category structure according to which the image data are classified. Furthermore we developed experimentally a retrieval system for images of tray (or "Bon") and nests of boxes (or "Jubako"), and verified that the user can retrieve the expected images easily. We also use the function of similar image retrieval to detect the duplicate image registration, and to help the more detailed image retrieval.

Kawasaki Junko, Matsumoto Shikari, Fukimbara Kenji, Tanaka Takehiko, Nakagawa Masaru

IPSJ SIG Notes ( Information Processing Society of Japan (IPSJ) ) 2000 ( 44 ) 115 - 120 2000.05

We develop a support system which realizes collaborative designs of 3D computer graphics through a computer network. Although there have been developed several network collaboration support systems which deal with 3D graphics, they requires all the users to have the technical knowledge and skill to handle 3D graphics. Our system, however, permits communicating 2D images and text data, which enables smooth collaborations even if some users have little knowledge and skill of 3D graphics. This paper explains several components of our system; user authentication, user interface and distribution right.
