  • System for natural language interaction with financial data
    Patent number: 10754881
    Abstract: The present invention is directed toward a system for database querying using natural language generation, which comprises identifying a first set of entities corresponding to an indexed data set in response to a user query, generating a ranked list of query intents using the first set of entities, wherein each item of the list of query intents represents a second set of entities associated with the user query and iterating over the ranked list of query intents to identify a top ranked intent associated to one of a set of predefined query plans. The predefined query plan associated with the top rank intent is executed using the set of entities corresponding to the top ranked intent, the predefined query plan comprising one or more search actions against the indexed data set. A first set of results is then received and a description is generated and transmitted.
