三词型术语抽取研究

Research on Tri-word Term Extraction

主要讨论了由三个词组成的术语的抽取问题。首先从实验语料中抽取了三个词组成的词串,利用语法规则剔除了不符合要求的三词串,最后对剩下的三词串进行了人工判别,判断其是否为术语。研究发现:1)由三个词组成的术语数量相对较少;2)所获得术语中被赋予新含义的术语占多数;3)同一领域术语间的流通性不同;4)三个以上的词组成的术语仍然存在,只是数量直线下降。

This paper mainly discussed the topic of tri-word ter^n extraction. We extracted all the linguistic strings for^ned by three words from the corpus, and filtered those illegal phrases based on the rule of grammar, and judge whether the rest of tri-word linguistic strings could be identified as terms. Our conclusions a re： 1） there are a relatively small number of tri-word terms in the corpus; 2） many tri-word terms have been given new meanings; 3） terms in the same field have different negotiability; 4） there are terms formed by more than three words in the corpus,but the number of this kind term is falling sharply.
