Web search engines are designed to search information in the web database and to return dynamic web pages.Data unit's returns from the databases and information technology are accessible through HTML form-based interfaces and web technology.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.To reduce human efforts a multi-annotator approach is proposed to automatically extract data units and assign labels.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.
