Abstract
A method, system, and computer-usable medium are disclosed for processing a search query that includes context based exclusion criteria. A search query is analyzed as to a subject, topic, noun phrase and query intent. Negative exclusion context and emphasis of the search query are determined with a filter word list to refine the query intent. A knowledge graph is created based on the search query. A set of branches of the knowledge graph is determined from which information is retrieved. Negative intent branches are identified based on the exclusion context and pruning is performed on the negative intent branches from the knowledge graph.
