- Abstract
- In order to make the result of XML keyword search more in line with the user’s intent, according to related studies about deficiencies that set definition corresponds to user’s query intention, this paper analyzes the node types and matching keywords from the user’s view and in the node levels on the effect of the search results, thus put forward the result set definition based on classification of node and hierarchical semantic. In meaningful entity as the basic semantic units, to organize and screen the search results according to hierarchical semantic, return the smallest piece of information to meet the user's query intention. This method achieves a SAX event in handling algorithm based on the transfer of information from stack realize path, and at last experiments on different data sets.
