Web Question Answering: Beyond Factoids


Web search engines have made great progress at answering factoid queries, such as "how many people live in Australia?". However, for more complex or broad questions which could benefit from a longer response (e.g., "history of Australia"), current search engine resort to returning a link to a detailed web document. Questions submitted on the Web can be either short and ambiguous (such as Web queries to a search engine), or long and detailed (such as questions posted in forums or question answering sites). Furthermore, searcher questions are diverse, ranging from advice on fixing a broken sink to requests for opinions on the best basketball player of all time. In this workshop we aim to explore the boundaries of Web question answering to better understand the spectrum of approaches and possible responses that are more detailed than a short fact, yet are more useful than a full result list. The workshop will provide a forum to explore the specific challenges associated with Web QA, such as query understanding, answer extraction, and source selection. We hope to bring together researchers working on, or interested in, question answering on the Web to share latest research results or ideas, and to discuss future directions.
