An Object-level Query and Scoring Strategy for VCAS
Hongkang Lin - · Computer Technology and Development · 2013
There are several ways to query the XML documents.For the users who have a smattering of the structure of the documents,can use the vague content and structure query,named VCAS query.In this paper,an approach for VCAS query and scoring based on an object-level XML data model was proposed.The XML documents were regarded as many intersect object trees in the approach,and the matches of the query were ISO or IRO.This approach could filter many meaningless matches and improves query efficiency.In this paper,the existing scoring methods were also improved.More content constraints were mined for scoring,and get more close to the user's intention.The experiments demonstrate the effectiveness of the proposed methods.
