Abstract:
A machine-implementable method for automatic extension of results obtained by querying a database of relationally organized data and expressed in tabular row and column format, each database table including a plurality of rows (tuples) and a plurality of columns (variables) defined over counterpart domains of values, said method comprising the steps of:(a) applying a formatted query designating at least one table, at least one column variable, and at least one predicate constraint to the designated table of said database and retrieving tuples of values satisfying the predicate constraints; (b) computing indexes of association among the previously selected and nonselected column variables and modifying the formatted query to include those nonselected column variables having respective indexes of association exceeding a predetermined threshold; and (c) repeating steps (a) and (b) until a stop condition occurs.
