comparing word sense based language model to other language models, the experiments based on the corpus of trec shows that wslm method has a better performance than the traditional td-idf method . if a more powerful word sense disambiguation tool is used, the result could be improved . in the retrieval results re-ranking part, we use a combination method which combines the retrieval results of different system by linear interpolation 在基于词义语言模型的信息检索研究中,介绍了同义词词典的词义表示方法,在实验中使用trec语料把基于词义的语言模型并与其他语言模型进行了比较,实验表明,基于词义的语言模型方法要好于传统的td-idf方法,如果有更加精准的词义消歧工具,实验结果还会有进一步提高。
