A WWW-based Melody Retrieval System

あらまし 本論文では,WWW上で動作する,歌声の旋律からその曲のタイトルを検索するシステムについ て述べる.歌声による検索では,入力の旋律情報(音高・音長)が正確とは限らないため,しきい値によってそ れらを粗い旋律情報に変換したものを検索キーとし,データベースの曲とのマッチングを行う.しかし,このた めの適切なしきい値の設定は難しく,特に音長情報においては,有効な検索キーを得ることが困難であった.ま た,粗い旋律情報では正答の絞込みも難しい.そこで,本研究では( 1)有効な検索キーを得るための最適なし きい値を設定する手法, ( 2)データベースの曲から正答の曲の候補を精度良く絞り込むためのマッチング手法の 二つを提案することで,従来手法よりも正答率の高い検索を実現し,WWW上で複数の利用者が活用できるシ ステムを構築できた. キーワ ドー 音楽データベース,メロディ検索,WWWアプ...

Document image database retrieval and browsing using texture analysis

A system is presented that uses texture to retrieve and browse images stored in a large document image database. A method of graphically generating a candidate search image is used that shows the visual layout and content of a target document. All images similar to this candidate are returned for the purpose of browsing orfurther query. The system is accessed using a World wide Web (Web) browse...

Supporting cooperative WWW browsing: a proxy-based approach

The paper presents a system for synchronous cooperative browsing that permits users within a workgroup to share information and cooperate toward a common goal. The system implementation is based on a Java proxy, to achieve portability without requiring modification neither to browsers nor to servers. In addition, the paper shows that the implemented system defines a general framework for intera...

The PACRAT system: an extensible WWW-based system for correlated sequence retrieval, storage and analysis

With PACRAT (Patterns, Analyses, Correlations. Remote Archive Testbed) we present an online database solution to the problem of accessing high-confidence sequences with specific relationships to classes of genes, such as upstream intergenic regions attached to tRNA genes. In addition the software contains a data warehousing and analysis-facilitating suite to streamline the process of analyzing ...
