Abstract (en)
[origin: WO2014127500A1] Methods, systems, and computer-readable media are provided for natural language processing based search. In some embodiments, a search system may parse a received search query and build a structured search. In some embodiments, building a structure search includes building a phrase tree based on the received search query, and building a query tree based on the phrase tree and data stored in a data structure such as a knowledge graph. In some embodiments, search results are retrieved from the data structure using the query tree. In some embodiments, the search system identifies filter facets and filters search results using query trees and relationships in the data structure.
