目前，世界各國學者都十分重視語言信息處理的知識資源的建設，知識包括詞彙學知識、句法學知識、語義學知識、語用學知識乃至常識方面的知識，核心問題是語義學知識。在語義學知識中，詞彙的語義知識是最基本最重要的語義知識。在過去的10 年中，我們清華大學和合作者對漢語實詞中主要的語類（例如：動詞、形容詞、名詞）的詞彙語義知識進行了系統、全面的研究，並且研製出“現代漢語述語動詞機器詞典”、“現代漢語述語形容詞機器詞典”、“現代漢語名詞槽關係系統”和“現代漢語語義分類詞典”。但是漢語虛詞的詞彙語義知識的研究特別是面向信息處理用的虛詞的詞彙語義知識的研究至今還是一個空白點。本文首先討論了漢語虛詞研究對漢語信息處理的意義。漢語是孤立語、詞根分析型語言，大多數漢語詞彙本身不能明顯地表達語法意義，句法手段主要靠虛詞和語序，況且虛詞對表示語態、語氣、時態體貌、能願情態、句子關係、程度、範圍、引入對象等句子語義和篇章結構有關鍵的作用，因此漢語虛詞詞彙語義研究對漢語信息處理有著特別重要的意義。其次，本文介紹了一個信息處理用現代漢語虛詞義類詞典的探索研究，是在漢語的語義層面上研究漢語虛詞的分類的二十一世紀的表達類，亦即研究一個信息處理用現代漢語句子情態表示系統。然後，本文展示了我們初步研究的成果，我們將虛詞義類初步分為語態範疇、時態體貌範疇、語氣範疇、能願情態範疇、肯定否定範疇、（句子）關係範疇、程度範疇、範圍範疇、對象範疇、其他範疇等十大範疇，每個大範疇根據虛詞表達的意義不同而再分為若干中範疇和小範疇。再之後，本文提出信息處理用現代漢語虛詞義類詞典工作單的信息項的設計設想。最後，論文還倡議建立現代漢語語義知識庫平台。

At present, worldwide scholars from different countries attach great importance to the knowledge resource construction of language information processing. Knowledge includes the aspects of lexicology, syntax, semantics, pragmatics and even general knowledge. The knowledge of semantics is the core, of which the most basic and most important one is the semantic knowledge of vocabulary. During the last 10 years, scholars of Tsinghua University and Cooperators have conducted systematic and complete studies on lexical semantic knowledge of the main categories of Chinese content words (including verb, adjective, noun, etc), and developed and studied “the Machine Tractable Dictionary of Contemporary
Chinese Predicate Verbs”, “the Machine Tractable Dictionary of Contemporary Chinese Predicate Adjectives”, “the System of Relations of Slots Centering on Nouns for Contemporary Chinese”, and “the Thesaurus Dictionary of Contemporary Chinese for Information Processing”. However, research on lexical semantic knowledge for information processing in particular of Chinese functional words has so far been limited. Firstly, this paper discusses the value of functional words in Chinese Information Processing. Chinese is a language whose typology involves isolated language and root-word-based analytical language. The vast majority of Chinese words can not themselves clearly express grammatical sense.
Chinese syntactical methods mainly depend on the use of functional words and word order. In addition it is important that Chinese functional words express meaning of sentences and structures of texts, e.g. voice, tense & acpect, mood, modality, positive and negative, relation of sentences, degree, range, draw into object, etc. Therefore, the study of lexical semantics of Chinese functional words is great importance to Chinese Information Processing. Secondly, this paper introduces our research on the Machine Tractable Thesaurus Dictionary of Contemporary Chinese Functional Words. The results of our initial research are presented. The Chinese functional words are divided into ten main-level categories,
e.g. Voice Category, Tense & Aspect Category, Mood Category, Modality
Category, Positive and Negative Category, Relation Category of Sentences, Degree Category, Range Category, Object Category, Other Category, etc. Each of main-level category is divided into a number of middle-level categories or minor-level category once and again according to expressing different meaning. This paper also presents some ideas of designing information terms for dictionary entries. Finally, we proposes the conception of constructing a base platform for the Contemporary Chinese Semantic Knowledge Bank.
