Crawling the web for structured documents

Structured Information Retrieval is gaining a lot of interest in recent years, as this kind of information is becoming an invaluable asset for professional communities such as Software Engineering. Most of the research has focused on XML documents, with initiatives like INEX to bring together and evaluate new techniques focused on structured information. Despite the use of XML documents is the immediate choice, the Web is filled with several other types of structured information, which account for millions of other documents. These documents may be collected directly using standard Web search engines like Google and Yahoo, or following specific search patterns in online repositories like SourceForge.

This kind of tool could help building large test collections...
