摘要 在文本检索过程中充分利用词语之间的上下文关系有助于提高检索性能。首先对已有的相关工作进行综述;然后针对已有研究对词语上下文关系应用不足的现状,提出一种基于词语上下文关系的文本检索算法;最后通过实验对该算法进行验证。 Fully utilizing the term context relations in text retrieval process helps to improve the retrieval performance. The related work is firstly summarized. Then, according to the deficiencies in applying term context relations, a text retrieval algorithm based on term context relations is presented. Finally, the algorithm is verified by experiment.
