Abstract

Question answering communities such as Yahoo! Answers and StackOverflow have emerged as popular as well as effective means of information resource on the web. One interesting analysis is to keep track of the lifetime of a question. We also plan to solve the problem of identifying sufficiently answered questions. Given a question, identifying the expertise in a domain is also an interesting question whose answer we ll try to find.
