Disclosed is a computer-accessible database composed of a list of non-generic words contained in a plurality of digitally encoded texts. Associated with each term is a selectivity value or values that are related to the frequency of occurrence of that word in at least one library of texts in a field, relative to the frequency of occurrence of the same word in one or more libraries of texts in one or more other fields, respectively. Also associated with each term are one or more text identifiers identifying one or more of the digitally processed texts containing that word. Each text identifier may be further associated with sentence and word-number identifiers that identify the sentence and word number(s) of a given database word.
