    In information retrieval, Algebra Theory is one of significant tools of Retrieval Modeling. The models on the basis of Algebra overcome the fault that partial matching can not be implemented within Boolean Model, then become more and more popular. This article analyses the Vector Space Model based on Algebra, and expands the model: expresses the index terms with minterm in order to reflect the relationship between terms, uses singular value decomposition to present the semantic structure of documents. At last, makes the compare between these models.

    RDF Site Summary (RSS) is lightweight,multipurpose, extensible metadata description and syndication format. Because of its features of simplicity, standardization, generalization and easy to use, more and more high-quality scientific websites choose to use RSS to publish their new information. The RSS-based Science and Technology Information Syndication System is a system aiming at syndicate the high-quality RSS information published by many scientific websites in RSS format. It can help librarians gather the latest science and technology information from websites and help them to trace, to monitor, to discover and to analyze the progress of sciences.
