ViNTs: Visual information aNd Tag structure based wrapper generator

Introduction Test bed Demo 1 Demo 2 Contacts

Demo 2: ViNTs a tool for automatically producing the wrappers for any given search engines. The demo here needs only the URL of a search engine’s cover page (a web page that contains the search engine form) and a query string. The demo program will fetch the cover page, extract the search engine form, generate probe queries to get sample pages, and then build wrapper from those automatically fetched sample pages. After that, the provided query will be sent to the search engine and its returned page will be fetched, then the built wrapper will be applied to extract search result records. Since the connection to search engines can not be guaranteed successful, the performance of demo 2 will be lower than demo 1 in which the connection to search engines are fulfilled by users via commercial browsers. Please provide a URL and a query below to run the demo: URL: Query: It will take a few minutes to build wrapper from a cover page url, please be patient.
