Hi Abdullah, Excuse me for breaking into your discussion, but from what I understand, you don't need to extract anything from Wikipedia yourself. The DBpedia (Live) project have the abstracts of all Wikipedia articles; if you have a list of article titles you can just retrieve them from DBpedia.
For example, if the topic/article on your list is "Frisbee", you use HTTP GET on <http://dbpedia.org/data/Frisbee>, which returns RDF data about the concept <http://dbpedia.org/resource/Frisbee>. The abstract you're looking for is the object in the triple(s) conforming to the pattern <http://dbpedia.org/resource/Flying_disc> dbpedia-owl:abstract [object] . (Frisbee redirects to Flying disc.) If your list is very very long, you'd better download a dump of all abstracts, load them in a triple store and use SPARQL to extract the abstracts you need, or perform your queries directly on the file using a SPARQL engine. I hope this answers your question. If the concepts on your list do not match any DBpedia resources directly, you will need to perform text searches on the abstracts (you can using SPARQL, to some degree, or perhaps the Lookup service) or perhaps even start to think of Topic Modelling, but IMHO other platforms are better suited to questions about these topics. StackOverflow, for example, has lots of question about using SPARQL with DBpedia. Good luck!
