【摘要】 如何实现本体的存储才能更有利于Web查询是个难点。水平存储和垂直存储是两种应用很广泛的本体存储方式,通过在本体进化中的应用比较得出,垂直存储比水平存储在数据更新方面更有优势。本文讨论了怎样在垂直存储中建立部分索引,以及部分索引应用在垂直存储中的三种情况。这三种情况都不需要对整个表进行扫描,就可以找到所需数据,从不同程度提高了本体的检索效率。更多还原

【Abstract】 Effective ontology storage in Web search is a well-known difficult problem.The horizontal storage and vertical storage are the most popular methods.It analyses and compares the application of the horizontal storage and vertical storage,concluding the latter superior in data updating.It also discusses how to develop partial index for vertical storage and applies it to three test cases.In the three cases,partial index proves helpful to the searching program in finding the needed data without scanning the whole table and hence improves the efficiency of retrieval.更多还原
