In recent years, community Question Answering forums such as StackOverflow, Quora, Qatar Living, etc. have gained a lot of popularity. As such forums are typically not moderated, this results in noisy and redundant content; yet, they are highly valued by users as a source of information. I will explore three general problems related to such forums, focusing on Qatar Living: (i) deciding which answers are good, (ii) finding related/duplicated questions, and (iii) finding good answers to a new question. This will involve models based on deep learning and semantic/syntactic kernels. I will further discuss extensions of this work in directions such as application to Arabic, cross-language question answering, fact checking, trollness detection, answer justification, and interactive question answering.
