Design and implementation of influenza Question Answering System based on multi-strategies

To extract the answer of influenza Question Answering System, a Question Answering System model based on multi-strategies was presented. Firstly, the user´s input question was matched in FAQ base of the system. If the question can be found in the FAQ base, the answer is outputted. Otherwise, the influenza information ontology was utilized and shallow semantic analysis was used to generate the question vector, then, SPARQL query was utilized. At last, the answer was acquired by querying influenza ontology. The experiments did prove that it was feasible to use the method to develop a question answering system, that it was valuable for further study in more depth.
