Supervised Data Extraction

Résumé

The process of data extraction from internet sources have been
originating the interest of the scientific society for the past years. However there
are still no well established standards because of the heterogeneous nature of
the information in the Global Network. Nevertheless there is still something in
common – all the data is available in HTML format for compatibility reasons.
This article presents our methodology and the prototype system we've created
to extract data from HTML pages. We use XPath as data extraction language
and have developed a methodology for visual wrapper generation. Our
approach takes advantage of the implicit correlation between the data and the
surrounding structure. Some evaluation tests are given also in order justify our
methods.
