Abstract
Methods and systems are provided for a question answering. In some implementations, a data element to be updated is identified in a knowledge graph and a query is generated based at least in part on the data element. The query is provided to a query processing engine. Information is received from the query processing engine in response to the query. The knowledge graph is updated based at least in part on the received information.
Claims24
A computer implemented method comprising:
- identifying an entity reference in a knowledge graph, wherein the entity reference corresponds to an entity type;
- identifying a missing data element, wherein the data element is associated with the entity reference;
- generating a query based at least in part on the missing data element and the entity type;
- providing the query to a query processing engine;
- receiving information from the query processing engine in response to the query;
- and
- updating the knowledge graph based at least in part on the received information.
