Answering natural language table queries through semantic table representation

摘要

According to one exemplary embodiment, a method for finding an answer to a query from a table is provided. The method may include receiving the query and the table. The method may also include generating a hierarchical representation based on the received table, whereby the hierarchical representation comprises a primary tree and a secondary tree. The method may then include mapping the primary tree to the secondary tree. The method may further include generating a plurality of predicate triples in a semantic relationship form based on the primary tree and the secondary tree. The method may also include determining if a predicate triple within the plurality of predicate triples matches the query using query-side and table-side context and semantics. The method may then include adding the predicate triple within the plurality of predicate triples to a plurality of candidate answers based on determining that the predicate triple matches the query.
