重み付き隣接行列に基づいてグラフの点集合をファジークラスタに分割するグラフスペクトル法の1種を提案する.本方法では点集合から一つのファジークラスタを抽出する問題を固有値問題として定式化し,これを反復的に適用して逐次にクラスタを抽出していく.まず無向グラフについて,類似度行列に基づくクラスタ抽出法を適用し,それを有向グラフや2部無向グラフに拡張してウェブページのリンク構造の抽出やキーワードによる画像ブラウジング検索に応用する.また数量化3類を用いてクラスタの構造を視覚化する1種のグラフ描画法も提案する.

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.

In this paper, we present a system for computer-aided thinking. We propose the idea of reflecting the mental world indirectly in a metric space, and thereby supporting human thinking activity such as construction and creation of new ideas. We use a method of mapping text-objects into metric spaces in order to deal with texts. Results of experiments using our implemented system, named CAT1 (Computer-Aided Thinking, version 1), are given. We show that a user of our system can get effective stimuli to his/her further thinking. The paper also gives a discussion about potential of the CAT1 to be used for group works.

Reforms in government agencies, including creation of the Cabinet Office and reorganizations in agencies, the Information Disclosure Law, and introduction of the all-government policy evaluation system, all realized in 2001, have a potential impact on the administration of Japan. The all-government policy evaluation system was prepared on the basis of the final report of the Administration Reform Council, and implemented in January 2001. Standard guidelines for the system were established, and the general framework of the system provided by the guidelines was translated into the Policy Evaluation Law. The guidelines define the purpose, concept and scope of evaluation; bodies executing evaluation ; timing of evaluation ; necessity, efficiency, effectiveness, equality and priority as the evaluation criteria ; and project, output and general evaluation as the evaluation approaches. The guidelines also require the government agencies, including the Ministry of Public Management, Home Affairs, Posts and Telecommunications, to make their policies reflect evaluation results, publish evaluation results, and establish practical guidelines for implementation of policy evaluation. The Policy Evaluation Law also stipulates establishment of a basic policy of the Government on policy evaluation, master plans and annual schedules for agencies. The effectiveness of the system depends on appropriate implementation of policy evaluation and proper use of its results. This will be realized more easily by adopting generally accepted evaluation methods and improving them gradually, rather than by imposing uniformly a sophisticated and exacting method.

伝統的な木構造を用いたファイルシステムが広範に使用されているが,各ファイルのコンテンツによる分類や関係付けの有効な手法が不足している.そのような単純なファイルシステムでは,キーワードを指定した効果的なファイル検索ができないという問題を抱えている.コンテンツに基づく情報検索を可能にするため,各ファイルに関するタグ情報を活用するファイル管理の新しい手法を設計している.本報告では,我々が作成しているファイル管理システムのGUIを紹介し,併せて,形態素解析によるファイル属性からのキーワード抽出,DBMSによるキーワード操作およびキーワードに基づく情報検索などを用いた,プロトタイプ実装についても言及する.Conventional tree-structured file systems have been widely used, but they have lacked a useful mechanism to classify and relate their files according to the contents of each file. And such simple file systems are suffering from efficient retrieval of their files by specifying keywords. In order to perform content-based information retrieval, a new scheme of file management is designed to utilize tagged information about each file. In this report, we will introduce a GUI of our file management system. And we will describe its prototype implementation by means of keyword extraction from file attributes with morphological analysis, keyword manipulation through DBMS and information retrieval based on keywords.

The purpose of this paper is to examine the formation of "disparities" in the transition from school to work, and to discuss ideal methods for support. In the early 21st century, young people were able to become full-time workers even if they had become part-time workers after leaving school. In other words, Japanese society compensated for the initial "disparity" in the transition from school to work. However, the following two points were clarified in February 2006, according to a survey carried out on 2,000 young people in Tokyo. First, in the period from 2001 to 2006, the selection of full time worker was nearly completed at the point when young people left school. Second, academic background is growing and social background is weakening as factors for the selection of full-time workers. To put a brake on the expansion of "disparities," it is necessary to secure higher education as a right, and create laws to provide equal conditions to irregular workers, and to provide support for the transition from "Freeter" (job-hopping part-time workers) to full time worker.

現在我々は,「複数の人がメーリングリストを用いて議論しながら共有文書を作成(修正)する」という状況で,議論した結果に基づき発生する共有文書の修正作業を支援することを目的とした,以下のような特徴を持つシステムを研究している.(1)メーリングリスト上に発生した会話を構造化し,わかりやすい形式にて表示する機能(2)会話情報から共有文書の修正に関するToDoリストを作成し,対象文書の修正状態に基づきToDoリストを更新する機能本稿では,本システムの設計方針,機能の概要,実装後のシステムの評価対象について述べる.We currently investigate a system to support a modification process of a shared document based on a discussion result under the situation such that several people cooperatively create a document discussing in a mailing list. The system has the following features: 1. Structure the conversation in a mailing list and visualize the information; and 2. Create a ToDo list about modification of a shared document from a mail data and update a modification state in the list after the document is modified. In this paper, we describe the design policy, the overview of the features, and the evaluation points after the completion of the implementation.

Users' personal information interests is an important for developing more personally adaptive system to search and to collect information increased. Recently, user profiling system has been used in several research system. However, evaluation approach of these systems was lack of empirical investigation using users' explicit desire. In this paper, we show the evaluation method for user profile using users' search queries as explicit desire. After the experiment, we could confirm the effectiveness of the method.

There are four approaches to the scientific study of teachers, viz., historical, administrative, comparative and sociological. Sociology of teachers is so fragmental that not all sorts of teachers are covered by it and that it does disclose the most remarkable and urgent trait of contemporary teachers neither. By and large it studies elementary and secondary school teachers, neglecting teachers of university, kindergarten and other institutions. Although there are a great many differences between various categories of teachers, sociology considers only the general characteristics of teachers. It is proposed here that the most important trait of teachers is their conflict, inner as well as outer. Profession in bureaucracy is, theoretically, responsible for their conflict, because while teachers as professionals demand freedom and autonomy on one hand, bureaucracy by which they are employed asks them to follow its orders and objectives on the other. Thus there should be a sociology of teachers constructed around the concept of coflict. Distinct from other professions, teaching is characterized by such tendencies as great and socially indispensable number, diffused bureaucracy, coexistence of freedom and restriction and continuity of career in school both before and after employment. Furthermore, teachers in contemporary Japan are experiencing new types of conflict, namely conflicts with students and with out-of-school teachers, for which is responsible the rapid transition to post-industrialism, where school teachers are losing authority and prestige they used to enjoy. Thus the present article proposes to study teachers in contemporary Japan in terms of conflict and discusses its supposed conditions.
