一种可扩展的汉语指同求解方法

提出了一种可扩展的汉语指同求解方法，主要针对汉语篇章中与代词和定指短语相关的指同求解．该方法分为基本指同求解算法和可扩展部分两个组成部分．基本指同求解算法基于定心理论，其中实现了一些通用的指同求解策略和规则．基本算法虽已具有一定的正确率，但对于汉语指同求解来说仍不够完善．可扩展部分引入了错误修正规则对基本算法的求解错误进行修正，使求解正确率得到进一步的提高．其中给出了错误修正规则的一般形式、获取途径及应用方法，还结合若干规则实例来表明错误修正规则的有效性．对该方法进行了实现并进行了测试运行，结果表明该方法是行之有效的

An Extendible Method for Resolving Co-reference in Chinese Discourse

Focused on pronominal and definite nominal anaphora, this method is divided into two parts:the baseline co reference resolution algorithm and the extendible part. The baseline algorithm based on centering theory implements some general strategies and rules for co reference resolution. Although the baseline algorithm can do co reference resolution with a certain precision, it is still not good enough for resolving co reference in Chinese discourse. The extendible part introduces error correction rules which can correct the errors in the output of the baseline algorithm to achieve higher accuracy. The general representation, the method to get rules and the application method pertaining to error correction rule were discussed. Some examples were given to show the effectiveness of the error correction rule. The method was implemented and tested. The result shows that the proposed method is promising.
