Numeric data type support for cognitive intelligence queries

Abstract:

A computer-implemented method, cognitive intelligence server and computer program product adapt a relational database containing numeric data types. At least one numeric token in the relational database is converted to a textual form. Text is produced based on relations of tokens in the relational database. A set of word vectors is produced based on the text. A cognitive intelligence query, expressed as a structured query language (SQL) query, may be applied to the relational database using the set of word vectors. At least one numeric token in the relational database may be converted to a typed string comprising a heading for a column in the relational database for which the token appears and the numeric value. Converting at least one numeric token in the relational database may comprise clustering tokens in a column of the relational database using a clustering algorithm and replacing each token in the column by a cluster identifier.
