Abstract

Abstract: Taking into account that many existing name disambiguation approaches are not suitable for documents with few features, this paper put forward a method that can get more features related to documents through search engine extension with the help of rich Internet resources. Firstly, four types of queries were constructed according to the characteristics of the search engine rules, and then search was done based on those query rules and the first k documents were returned. Lastly, a feature selection method of Document Frequency (DF) was used in these documents and the selected features were added to the original documents. The experimental results show that the query expansion approach can improve the performance of name disambiguation and make F-measure increase from 76% to 81%.

Key words: query expansion, search engine, name disambiguation, named entity

摘要： 针对现有很多基于特征的人名消歧方法不适用于文档本身特征稀疏的问题,提出一种借助丰富的互联网资源,使用搜索引擎查询并扩展出更多与文档相关特征的方法。首先根据搜索引擎的特性构建了四类查询规则,然后通过这些查询规则进行搜索并返回前k个文档,最后对这些文档使用文档频率(DF)方法进行特征选择,并将选择的特征加入到原文档中。实验证明,该方法能显著提高人名消歧系统的性能,平均F值由76%增加到81%。
