【摘要】：为提高维吾尔文网络内容查询的扩展性能,提出一种将维语同义词和互联网资源相结合的扩展词构建算法。利用维吾尔语同义词词典、近义词词典和反义词词典等建立基本候选词库,将互联网作为超大规模语料库,以搜索引擎为工具,使用改进的点互信息对基本扩展词进行相似度评价,选取前N个词形成候选扩展词库1,对包含关键词的互联网语料,基于局部共现和点互信息分析,构建候选扩展词库2,对上述2种候选扩展词库加权求和,按顺序选择部分词为扩展词。通过搜索引擎实现扩展查询验证,结果表明,与常规查询和同义词查询扩展算法相比,该算法能明显提高查询的准确率。
[Abstract]:To improve the performance of network expansion for Uighur content query, a Uighur synonym expansion words and Internet resources of the combination algorithm. Using Uyghur Dictionary of synonyms, antonyms and Synonyms Dictionary dictionary establishment candidate thesaurus, the Internet as a super large scale corpus, using the search engine as the tool, using the improved point mutual information similarity evaluation of extended words, select the first N words form the candidate expansion thesaurus 1, to contain the keywords of the internet corpus, and co-occurrence mutual information based on local analysis, construct the candidate expansion thesaurus 2, extension of the above 2 kinds of candidate thesaurus weighted sum, in order to select some words for expansion words. Through the search engine to achieve the expansion of query verification, the results show that the conventional query and synonym query expansion algorithm, the algorithm can significantly improve the accuracy of the query.
