摘要
在汉语自动分词系统中,歧义字段的切分直接影响着分词的精度。本文深入地分析了歧义字段产生的根源,据此给出了歧义字段的详细分类和消除每一类歧义字段的有效方法。并在对歧义字段进行统计分析的基础上提出了切分精度的级别划分。
In automatic segmentation system (ASS) of Chinese words, the segmentation of different meanings field influences the precision of the words segmentation.This paper explores the cause of the different meanings field, according to the cause, the elaboration on how to classify the different meaning fields are put forward,the effective method of eliminating every different meanings field is provided also.Furthermore, we present hierarchies of segmentation precision in this paper on the foundation of statistics.
