By using Simple Principal Component Analysis(SPCA), high-dimensional and sparse vectors is transformed into the low-dimensional vector space, namely the space representing the latent semantic meanings of words. An experimental information retrieval system based on the proposed method has been built. ...

This paper proposes a method to improve retrieval performance of the vector space model (VSM) in part by utilizing user-supplied information of those documents that are relevant to the query in question. In addition to the user's relevance feedback information, information such as original documen...
The Vector Space Model is an algebraic model used for InformationRetrieval. It represent natural language document in a formal manner by the use of vectors in a multi-dimensional space, andallows decisions to be made as to which documents are similar to each other and to the queries fired. ...
In this paper we, in essence, point out that the methods used in the current vector based systems are in conflict with the premises of the vector space model. The considerations, naturally, lead to how things might have been done differently. More importantly, it is felt that this investigat...
[译]Vector space model(向量空间模型) Vector space model(orterm vector model) is an algebraic model for representing text documents (and any objects, in general) as vectors of identifiers, such as, for example, index terms. It is used in information filtering, information retrieval, indexing ...

的解释。从广义的角度讲，检索包括“存贮”和“查找”两个过程。没有存贮就没有查找，存贮是为了查找，但查找必须有存贮，两者缺一不可。3 信息检索词汇（terms）“检索”（Retrieval）一词是一个外来词，来源于英语 “InformationRetrieval”（信息检索）Informationretrieval(IR)Informationaccess(obtain)Informationsearch...
