We generalize the task of finding question paraphrases in a question repository to a novel formulation in which known ques- tions are ranked based on their utility to a new, reference question. We manually annotate a dataset of 60 groups of ques- tions with a partial order relation reflect- ing the relative utility of questions inside each group, and use it to evaluate mean- ing and structure aware utility functions. Experimental evaluation demonstrates the importance of using structural informa- tion in estimating the relative usefulness of questions, holding the promise of in- creased usability for social QA sites.
