title: Mining Wikipedia for mapping relations for text mining
body: <p>I am planning to develop a web-based application which could crawl wikipedia for finding relations and store it in a database. By relations, I mean searching for a name say,'Bill Gates' and find his page, download it and pull out the various information from the page and store it in a database. Information may include his date of birth, his company and a few other things. But I need to know if there is any way to find these unique data from the page, so that I could store them in a database. Any specific books or algorithms would be greatly appreciated. Also mentioning of good opensource libraries would be helpful. </p>
  
  <p>Thank You</p>
