15. The method of claim 14 , further comprising receiving a natural query and processing the natural language query using the generated classifier.
14. A method for generating a classifier for performing a query to a given knowledge base, the given knowledge base including a plurality of predicates, a plurality of subjects and a plurality objects being related to each other, the method comprising: selecting one predicate from the plurality of predicates; generating, based on the given knowledge base, a plurality of triples, each triple of the plurality of triples including the one selected predicate and a subject of the plurality of subjects and an object of the plurality of objects related to the one selected predicate; generating a list of properties, the generating of the list of properties comprising performing a context-based query within the given knowledge base, each property of the list of properties being correlated to the subject and the object of one triple of the plurality of triples; generating a classifier having the list of properties related to the one selected predicate; and transforming a question or a portion of a document based on the generated classifier such that the question or the portion of the document includes a predefined predicate.
