摘要 本文对基于统计语言模型的信息检索进行了综述,介绍了目前基于统计语言模型信息检索中比较有代表性的模型,给出了语言模型估计中常用的几种平滑技术,将语言模型同目前流行信息检索模型进行了比较,在此基础上,指出了基于统计语言模型信息检索的研究方向。 Information retrieval (IR)based on statistical language model (SLM)and the smoothing technology related to SLM are generally introduced in this paper. By comparing with popular retrieval models of IR in the past years, the advantage of information retrieval based SLM is discussed in detail. At last, some research directions of information retrieval based on SLM are presented.
