A computer-implemented method according to one embodiment includes receiving a question in a natural language format; deriving a plurality of subqueries from the question; determining that a first subquery of the plurality of subqueries cannot be resolved utilizing a curated knowledge base; resolving the first subquery, utilizing unstructured text; and adjusting the curated knowledge base, utilizing the resolved first subquery.

Resolving queries using structured and unstructured data

Methods, systems, and computer program products for entity structured representation and variant generation are provided herein. A computer-implemented method includes automatically parsing instances of a given entity type into semantic components by implementing a parser based at least in part on (i) the given entity type and (ii) items of information relevant to the given entity type; generating, based at least in part on (i) the semantic components and (ii) information pertaining to one or more valid component-specific variants, one or more variants of the semantic components; creating, based at least in part on the one or more variants of the one or more semantic components, one or more variants of at least one instance of an entity associated with the given entity type; and outputting, to at least one user, the one or more variants of the at least one instance of the entity.
