A web database is a system for storing information that can then be accessed via a website. The result page obtained from Web DataBase (WDB) is Search Result Record (SRR). These SRRs contain multiple data units which is to be extracted and labeled semantically. The annotation approach contains three phases: alignment, annotation and annotation wrapper generation. In this paper, the authors present a Searching mechanism which perform searching from the annotated search result, frequently used data units are identified by join-based algorithm which include top-K ranking function.
