Aranca is a question answering system that extracts answers from the World Wide Web using knowledge annotation and knowledge mining techniques. Knowledge annotation, which utilizes semistructured databasc techniques, is effccdvc for answering large classes of commonly occurring questions. Knowledge mining, which utilizes statistical techniques, can leverage the massive amounts of data available on the eb to overcome many natural language processing challenges. Aranea integrates these two different paradigms of question answering into a single fraamework. For the TREC evaluation, we also explored the problem of answer projcction, or finding supporting documents for our eb-derived answers from the AQUAINT corpus.
