WANQA: An Approach for Identifying New Unanswerable Questions in Q&A Communities
Abstract
Big knowledge repositories are on the web and Question and Answer Communities (CQAs) are one of the most collaborative. Daily, their users post a large volume of questions and a great part of them receives no answers, becoming it useless content. Previous works that aim to solve this problem are dependent on the given characteristics of each community. This article proposes an approach based on a classification that results a model able to classify whether a new question is answerable or not. It uses features available in most CQAs. Experiments with data from different CQAs show that the proposal fulfills its goals.
