多级中文词库的研究

Research of a Multilevel Chinese Words Library

词库是汉字信息处理系统中词输入处理必须使用的重要数据结构。词库设计得是否合理,会影响到整个系统的性能。本文首先提出了词库性能的描述方法和多级词库结构,然后对词库性能作了分析,得出了词库性能对改善系统响应时间具有重要作用。最后,文章对动态词库内词的淘汰算法和词的自定义技术进行了讨论。

The words library is an important data structure in the word input processing of Chi- nese information processing system.The performance of the whole system depends directly on the reasonableness of design for its structure.This paper firstly offers a descriptive method for this per- formance and the multilevel words library structure.By analyzing the performance,the important infl- uence of the words library on the system response time is then pointed out.Finally,the elimination algorithms and self-defining words technique are discussed.
