Abstract
A method, computer program product and/or system is disclosed. According to an aspect of this invention, one or more processors receive a query of a first database, where the query includes: (i) an operand, and (ii) an operator indicating a distance-based similarity measure. One or more processors further determine a result set based on the query, wherein the result set includes a plurality of records, and wherein a record is included in the result set based on a vector nearest-neighbor computation between: (i) a first vector corresponding to the operand, and (ii) a second vector corresponding to the record, wherein the second vector is included in a vector space model that is based on a textual representation of the first database.
