Automatic Q&A method and system based on multi-knowledge base and integral linear programming ILP

The invention provides an automatic QA querying in the resource dictionary, and mapping to a plurality of entities and/or a plurality of relations from a plurality of text fragments of a natural sentence to construct a plurality of candidate resources; executing conversion on the candidate resources to obtain a plurality of corresponding templates; combining the text fragments, mapping, candidate resources, conversion and the templates as a disambiguation figure; performing integrated reasoning on the disambiguation figure according to the ILP, selecting at least one to-be-queried template to generate a standard query sentence. Through the adoption of the method provided by the invention, the natural sentence in the multi-knowledge base can be precisely queried.
