専門用語辞典の自動的ハイパーテキスト化の方法

抄録

This paper describes a method of automatic hypertext construction from an Encyclopedic Dictionary of Computer Science, which was originally published in a book form. By checking varieties of sentential styles, sentences which define the meaning of head words and other important words are first extracted from the dictionary. These include the sentences expressing synonyms and giving intensional and extensional definitions. Then these sentences are further analyzed and the keywords and their relations are extracted automatically by relatively simple natural language processing. These extracted terms which include head words and index terms are connected each other according to the extracted relations from the defining sentences. The whole text data which amounted 2 mega characters were stored in a workstation. We constructed a user-friendly interface on X-window system, which realizes varieties of accesses to required information. The system includes full text search facility which scans 4 mega bytes data in a few seconds. This method of automatic hypertext construction is applicable to other encyclopedic dictionaries.
