漢語詞彙語義研究及詞彙知識庫建設

Research on Chinese Lexical Semantic and the Construction of Lexical Knowledge Base

信息技術，特別是 Internet 上搜索引擎技術的需求為漢語詞彙語義的研究拓展了廣闊的空間。本文論述詞彙語義研究在自然語言處理技術中的意義以及自然語言處理技術對詞彙語義研究所提出的新要求；本文重點介紹北京大學計算語言學研究所面向自然語言處理研製中文詞彙知識庫的成果：(1)現代漢語語法信息詞典，(2)現代漢語語義詞典，(3)中文概念詞典，(4)現代漢語詞義標注語料庫。本文最後介紹將這些獨立存在的詞彙知識庫集成為綜合型語言知識庫的構想、技術方案和已經取得的階段性進展。

Information technology, especially search engine technology popular on the Internet, offers promising opportunities for future research into Chinese Lexical Semantics. This paper demonstrates the significance and the urgent need for lexical semantics in natural language processing. Chinese lexical resources developed by the Institute of Computational Linguistics of Peking University (ICL/PKU) is introduced in this paper, which contains mainly four components: (1) Grammatical Knowledge Base of Contemporary Chinese (GKB), (2) Chinese Semantic Dictionary (CSD), (3) Chinese Concept Dictionary (CCD), and (4) Word-Sense Tagging Corpus of Contemporary Chinese (CSC). Building a comprehensive language knowledge base by combining all existing language resources is proposed in the last section; main ideas, technological measures, progress to date are outlined.
