全文检索系统中动态索引技术的研究

Research on Dynamic Index Technology in Full Text Retrieval

全文检索是一种非常有效的信息检索技术,本文通过分析全文检索系统中静态索引技术的优缺点,以及影响动态性能的因素,提出一种基于互关联后继树模型的动态索引技术,该技术在不影响查询效率等性能的情况下,很好地解决了索引的更新问题,提高了索引的动态性能。

Full text retrieval is one of the most efficient technologies of information retrieving. This paper analyses the meritsand demeritsof static index technology in full text retrieval system,discusses the factors which may affect the dynamic features ofindex,then put forwards a kind of dynamic index technologybased on inter-relevant successive trees. This technology has goodperformancein solving the problem of updating index and enhancing its dynamic features, while not affecting inquiring efficiencyand other performances.
