Deep Web query interface selecting
Deep Web查询接口选择

As Web develops,more and more data has become available under Web query interface.Therefore,how to find the data-sources that are most relevant to the user's requirements has become more and more important.This paper presented a Deep Web query interface selection arithmetic,which completely depended on the characteristics of query interface.Given numerous heterogeneous Deep Web data sources,we aimed at selecting sources most relevant to the user's requirements.By allowing the users to input an imprecise initial query,our system found appropriate sources for them.We observed the characteristics of query interface and found out the relationships between predicates.Based on this discovery,an algorithm based on co-occurrence predicate model for capturing the relevance of attributes was designed.It can be used to select the sources most relevant to the user's requirments.
