Community-based question answering (cQA) services have accumulated millions of questions and their answers over time. In the process of accumulation, cQA ser- vices assume that questions always have unique best answers. However, with an in- depth analysis of questions and answers on cQA services, we find that the assump- tion cannot be true. According to the anal- ysis, at least 78% of the cQA best answers are reusable when similar questions are asked again, but no more than 48% of them are indeed the unique best answers. We conduct the analysis by proposing taxonomies for cQA questions and an- swers. To better reuse the cQA content, we also propose applying automatic sum- marization techniques to summarize an- swers. Our results show that question-type oriented summarization ...
