動詞語意的研究一直是語言學與自然語言處理及應用的一大課題。本文旨在綜論詞彙語意的剖析方法，並指出現有以處理大量訊息為目標的語意資料，無法呈現近義詞的語意區隔。唯有以語料庫為本，對照剖析動詞的共現結構、功能分布及語意限制，才能清楚界定語意和語法間的互動關係，進而釐清近義詞的關鍵屬性。動詞語意研究的最終目的即在找出具有影響語法表現的語意屬性。

　　　　　The importance of deciphering lexical knowledge, especially the eventive information encoded on verbs, has been highly recognized and various approaches have been proposed to represent lexical information that plays a crucial role in grammatical realization. In this paper, a subset of Mandarin verbs of communication-verbs of discussion-is explored in detail, with reference to the semantic properties characteristic of the whole class. While quantitative NLP approaches might tend to overlook some semantic details, it is shown that a corpus-based, contrastive analysis of near-synonyms can be most useful in extracting lexical information that is critical in differentiating verbs.
