1. A method, comprising: identifying a first classification, of a plurality of classifications relating a plurality of terms in a glossary to a set of values in a reference data management system, that relates a first term in the glossary to a first set of values in the reference data management system, wherein each of the plurality of classifications defines a set of valid values for each respective classified term; detecting a relationship between the first set of values and a second set of values in the reference data management system, by: identifying a first property of the second set of values defining an association between at least one member of the second set of values and a member of the first set of values; computing a weight for a second property of the second set of values; and determining that the weight for the second property exceeds a first predefined threshold; upon determining that a relevance score for a first value from the second set of values exceeds a second predefined threshold, identifying the first value to be classified with the first term in the glossary by operation of one or more computer processors; and creating a second classification relating the first term and the first value.
