Abstract
Deep Web contain vast amounts of information,existing search engines are difficult to search the contents.How to make the access to valuable information in Deep Web becomes a problem.This paper proposes a keyword-based Deep Web database query method,the method using the Nave Bayes algorithm to classify the Key words and log mining statistics of the sample database,eventually generate the SQL statement for the query.This method not only solves Deep Web in various fields of the database query,but also can be integrated with the existing search engine to help users to query quickly and efficiently.
