1. A method for representing call content in a searchable database, comprising the steps of:

transcribing call content of a call to text;

projecting the call content to vector space, wherein projecting comprises creating a call vector representative of the call content by indexing the call content using a content index dictionary;

determining a similarity measure for the call vector in relation to classes of an atomic-class dictionary which provides classification hierarchy descriptions of call data stored in a relational database; and

classifying the call content in the relational database in accordance with similarity measure for the call vector.
