Deep Web查询接口及其识别算法

Deep Web Query Interface and Identification Algorithms

查询接口是Deep Web的唯一入口,在对后台数据库展开研究时,查询接口的识别凸显重要。该文首先分析了查询接口的结构特点,并总结出一系列可用于进行查询接口识别的启发式规则,并通过概率计算对规则的使用顺序进行了优化,实验证明,具有较好的使用价值。

Query interface is the only entrance of Deep Web, so a study of the background database, the query interface is important for recognition. This paper analyzes the structural characteristics of query interfaces, and summarizes a series of query interface can he used for identification Heuristic rules, and rules through the use of probability, sequence is optimized experimental results show that the use of good value.
