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 在基于詞義語言模型的信息檢索研究中,介紹了同義詞詞典的詞義表示方法,在實驗中使用trec語料把基于詞義的語言模型并與其他語言模型進行了比較,實驗表明,基于詞義的語言模型方法要好于傳統(tǒng)的td-idf方法,如果有更加精準的詞義消歧工具,實驗結(jié)果還會有進一步提高。
