把词素作为基本资源,从语义上寻找他们组合成词的规律,可以辅助自然语言理解。该文首先参照《现代汉语词典》和知网标注了二字词的词素意义,继而从意合结构、意根分布、意指方式、意变类型四个角度标注了词素间的词化意义,最后综合词素意义和词化意义,在定量统计的基础上建立了一个二字词的语义描写体系。通过对论坛及《现代汉语词典》的新词进行实验,我们发现二字词的语义构词研究在普通未登录词的理解中具有一定的应用价值。

The approach to investigate the semantic rules in word- formation via the the granularity of the morpheme can help understand natural language .This paper first labeles the sense of the front and back morpheme of the two-character words by referring to the Modern Chinese Dictionary and HowNet. Then we labele the lexicalized meaning between the morphemes from the perspectives of the structure of semantic combination, the distribution of semantic root, the mode of semantic combination and the type of semantic variation. Finally, we combined the morpheme meaning with lexicalization meaning quantitatively to set up a semantic scheme to account for the two-character words . Tested by the two-character words from BBS and the Modern Chinese Dictionary, it reveals some applicationvalue on the understanding of common unknown words.
