Abstract:

For an extract description of threads information in question and answer(QnA)web forums, it is proposed to construct a QnA knowledge presentation model in the English language, and then an entire solution for the QnA knowledge system is presented, including data gathering, platform building and applications design.With pre-defined dictionary and grammatical analysis, the model draws semantic information, grammatical information and knowledge confidence into IR methods, in the form of statement sets and term sets with semantic links.Theoretical analysis shows that the statement model can provide an exact presentation for QnA knowledge, breaking through any limits from original QnA patterns and being adaptable to various query demands;the semantic links between terms can assist the statement model, in terms of deducing new from existing knowledge.The model makes use of both information retrieval(IR)and natural language processing(NLP)features, strengthening the knowledge presentation ability.Many knowledge-based applications built upon this model can be improved, providing better performance.
