Abstract

This paper describes a new methodology for enhancing the quality and relevance of suggestions provided to users of interactive Q/A systems. We show that by using Conditional Random Fields to combine relevance feedback gathered from users along with information derived from discourse structure and coherence, we can accurately identify irrelevant suggestions with nearly 90% F-measure.
