Paper Title: 
"Interactive Search Queries for Online Communities" 

Abstract: 
We introduce the problem of interactive search queries for online communities (ISQ-problem). In online communities users often try to leverage the combined community expertise to find answers for problems where neither a complete and accurate specification of the question nor the exploration of all possible answers is feasible. For instance, when trying to identify the species of an observed bird, users do not know which information is most relevant and how to properly specify it; nor do they want to browse through pictures of all possible species. We formally define the ISQ-problem as a problem of minimizing user effort, while guaranteeing interactive system response time. To deal with uncertain and missing user responses, we develop a probability-based framework and show that it allows us to optimally rank possible answers and select the right questions to ask. Estimating the required probabilities from crowd-sourced data while guaranteeing interactive response times, poses a serious data management challenge, for which we develop scalable algorithms. We also propose a novel technique that identifies those user responses that had the greatest impact on the answer ranking, allowing the user to revisit critical uncertain responses. Experiments show the feasibility of our approach.
