Results Search from Web Databases using automatic Annotation Wrapper

Abstract

Web database technologies define the way that these forms canconnect to and retrieve data from database servers.Now a day’s countlessdatabases have become web accessible through HTML form-based search interfaces. A typical result page returned from a WDB has multiple search result records (SRRs).Web search engines are designed to search information in the web database and to return dynamic web pages. Internet presents a huge amount of useful information which is usually formatted for its users, which makes it difficult to extract relevant data from various sources.  Web pages are retrieved when a query is submitted to the search interface. Each web page contains several search result records related to user query. Every SRR contains multiple data units each of which describes one aspect of a real-world entity. Then SRR get extracted and assigned meaningful labels. The Web has become the preferred medium for many database applications, such as e-commerce and digital libraries. After the successful extraction align the data units into different groups where, data inside the same group have the same semantic(meaning).Then automatically annotation wrapper can generated and used to annotate new result records from the same web database.
