信息检索模型是信息检索中的核心问题,一直是众多研究者研究的热点。但在过去的十年里,没有一个单一的检索模型被证明是最有效的。其中一个原因是独立假设。研究表明,在检索模型中加入有用信息可以提高检索模型的性能。由于图模型可以有效地对信息进行建模,本文采用马尔可夫网络来构造术语关系,将术语关系和信息检索模型统一建模。实验结果表明,该模型能够提高检索性能.
Information retrieval model is central in information retrieval, which have been studied by many researchers. But over the decade, no single retrieval model has proven to be most effective. One of the reasons is the term independent assumption. Research have shown that adding useful information to retrieval model can improve the performance of retrieval model. As graphical model can model information effectively, we use Markov network to construct the term relationship, and model the term relationship and information retrieval model in a unified framework. Experimental results show that our model can improve the retrieval performance.
