Jinsha Yuan · Dianzi xuebao · 2007
Traditional keyword-based search engine does not consider the additional information provided by the structure of XML documents,it returns imprecise results often;searching according to keywords and structure information of XML documents inputted is not suitable for contain users.Semantic search for XML data based on tag-keywords overcomes the limitations above, but its efficiency needs to be improved.This paper analyzes semantic information provided by the structure of XML documents deeply.It puts forward a new index structure for XML data and semantic related decision function between two nodes.Based on this,it proposes a fast semantic search algorithm for XML data.The search algorithm reduces the times to decide semantic correla- tion greatly.The experimental results with real data sets illustrate the effectiveness of the proposed algorithm.
