The study of association rules within groups of individuals in a database is interesting to define their characteristics and their behavior. In this paper, we define group association rules and we study interestingness measures for them. These evaluation measures can be used to rank groups of individuals and also rules within each group.

あらまし 本稿では,モバイル環境におけるWEB情報の活用に適した新しいインタフェースとして,情報ナ ビゲーションエージェントを提案する.これまでの情報検索システムは,検索結果のユーザへの表示とそれに基 づくクエリの変更を通して多くの情報をいかに絞り込んでいくかが中心的課題であり,デスクトップ環境での利 用に適した方法であった.それに対して我々のエージェントは,検索対象の属性の制約条件を用いて近似解を生 成し,ユーザとの対話を通して情報を得ることにより,漸近的によりよい情報へとナビゲートしていくことがで きる.その際に,エージェントがキーワード間の連想ルールを用いて検索条件の解決と新たな検索条件の追加を 行う手法を提案した.また,連想ルールを不用意に用いるとナビゲーションの失敗を導くため,統計的検定とグ ラフ構造の解析を用いた連想ルールの精錬を行うことを提案し,その有効性を確認した. ...

This paper examines the case for special and differential (S&D) treatment for developing countries within the WTO Agreement on Agriculture and the particular instruments or exemptions it should cover. The S&D treatment currently allowed to developing countries in the Agreement and the use they have made of it is first described. The range of proposals put forward by developing countries (and by...

In this paper, we study the issue of maintaining association rules in a large database of sales transactions. The maintenance of association rules can be mapped into the problem of maintaining large itemsets in the database. Because the mining of association rules is time-consuming, we need an efficient approach to maintain the large itemsets when the database is updated. In this paper, we pres...

To support more efficient video database management, this paper explores the concept of video association mining, with which the association patterns are characterized by sequentially associated video shots and their cluster information. Given a continuous video sequence V, the video shot segmentation mechanism is first introduced to parse it into discrete shots. We then cluster shots into visu...
