Abstract
A method, information processing system, and computer program storage product retrieve data from a database. A search request is received from a user for a set of data in at least one database. An ontology query over is performed over at least one ontology associated with at least one database resulting in an ontological dataset associated with the search request in response to receiving the search request from the user. The ontological dataset includes at least one of a set of synonyms, a set of hypernyms, and a set of hyponyms, associated with the search request. A data query is performed over data in the at least one database using the ontological dataset in response to performing the ontology query. The set of data is returned to the user based on the data query that has been performed.
