| Abstract: | 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. |
