##Lackbase (AGIW project) This repository contains a project made for the Web Informations Management course at Roma Tre University.

###Brief Freebase.com is a huge knowledge base, but is far from complete. We decided to extend a particular part of it:

• Nationality of the relation: Soccer Player, people.person.nationality, Nationality
• Stadium of the relation: Soccer Team, sports.sports_team.arena_stadium, Stadium

To make this happen we crawled a famous and big website about this topic: Transfermarkt.com. Using XPath queries we iteratively and automatically selected the data we wanted and we used it to extend the Freebase relations!

###Results

• 11% of new Players -> Nationality relations
• 13% of new Team -> Stadium relations
