基于非结构化文本检索模型综述
Review of unstructured text retrieval model
摘要
Abstract
With the promotion of informatization in working and daily life,the new unstructured text data is rapidly accumulating in many fields such as product description,users' Web comments,text information communication and so on,so it brings new challenges about how to find the real text information accurately and efficiently to meet users' demands.Retrieval model is the key for both retrieval accuracy and efficiency.Aiming at the retrieval requirements on massive text data,this paper summarized the definition and general framework of retrieval model,and then proposed a classification of retrieval models according to mathematical theory applied in different retrieval models.Based on the classification,the paper elaborated evolutionary process,the advantages,disadvantages and application scenarios of each model.Finally,it discussed both the specific challenges and researches of retrieval which focused on massive text data.关键词
