摘　　要：针对目前信息服务机构只能提供文献的检索服务而不提供表格检索功能这一现状,提出一种基于向量空间模型的表格检索算法,并从表格特征抽取、特征词权值设置、检索结果匹配排序等方面进行讨论,为未来表格检索服务提供一定的理论依据。According to the problem that most information institutions can only provide searching service for literature instead of tables, this paper proposes a table retrieval algorithm which is based on Vector Space Model （VSM）. Discussions are implemented from the aspects of table character extraction, term value setting, and search result ranking, which provide theoretical basis of the table retrieval services in the future.
