  • Patent number: 10068016
    Abstract: A natural language query is received, and an answer to the natural language query is determined. A message is formatted such that the message includes the answer, and metadata corresponding to the answer, the metadata including information to enable construction, using the metadata, of a sentence that rephrases the query and recites the answer.
    Type: Grant
    Filed: October 17, 2014
    Date of Patent: September 4, 2018
    Assignee: Wolfram Alpha LLC
    Inventors: Stephen Wolfram, Oyvind Tafjord
  • Patent number: 9213768
    Abstract: A word meaning or sense is determined in response to an actual user query in a system designed for computation, search, or other activities involving the processing of queries. Assumptions, which are attempts to disambiguate pieces of the user's query string, are generated. Generation of the assumptions is based on various heuristics and algorithms which are designed to disambiguate words which may connote multiple different entities, meanings, or senses given the context. Assumptions also may be ranked based on a set of criteria that does not require an elaborately constructed body of world knowledge to be created. A most likely assumption may be chosen for generating a machine-generated query and/or for generating query results.

  • Patent number: 8788524
    Abstract: A query in an imprecise syntax is received, and a plurality of assumptions relating to the meaning of the query are determined. One of the assumptions is chosen from the determined plurality of assumptions, and a first response to the query is generated based on the chosen assumption. A user interface mechanism is provided to permit a user to change the assumption on which the first response was based, and a second response to the query is generated based on the changed assumption.

  • Patent number: 8484015
    Abstract: An answer engine determines an entity related to a query from a user in a system designed for computation, search, or other activities involving the processing of queries. The system determines whether an entity page for the entity is stored in an answers database and, if so, retrieves and displays the stored entity page. If there is no stored entity page for the entity, the answer engine generates and displays an answer to the query and may optionally store the answer as an entity page. Additionally, the answer engine may pre-generate and store entity pages according to algorithmic variation of received queries and/or according to information received from external sources.
