Abstract
A method, apparatus, and computer program product are provided for generating a set of token sequences for at least a portion of a database, wherein each token in a sequence represents a respective database entity of the database; assigning, for each token in the set of token sequences, at least one corresponding vector from a set of vectors of a same dimension, wherein the at least one corresponding vector encodes relationships between the database entity of a token and other database entities of other tokens of the set of token sequences; and extracting, using a query language, information from the database based at least in part on the relationships encoded by the assigned vectors.
