Processing input text to generate the selectivity value of a word or word group in a library of texts in a field is related to the frequency of occurrence of that word or word group in library
First Claim
1. Machine-readable storage medium embodying computer-executable code which is operable, when used to control an electronic computer, to identify descriptive words or word groups contained in a digitally encoded input text, by the steps of:
- (i) processing the input text to generate a list of text words or word groups formed of proximately arranged words in said input text,(ii) selecting a text word or word group from (i) as a descriptive word or word group if that word or word group, respectively, has an above-threshold selectivity value in at least one library of texts in a field, wherethe selectivity value of a word or word group in a library of texts in a field is related to the frequency of occurrence of that word or word group in said library, relative to the frequency of occurrence of the same word or word group, respectively, in at least one other library of texts in at least one other fields, respectively, and(iii) storing or displaying the words or word groups selected in (ii) as descriptive words or word groups, respectively.

Abstract
Disclosed is an automated system, machine-readable storage medium embodying computer-executable code, and method for generating descriptive words and optionally, multi-word groups derived from a digitally encoded, natural-language input text that describes a concept, invention, or event in a selected field. The system includes (a) an electronic digital computer, (b) a database of words and optionally, word-groups derived from a plurality of texts, and (c) machine-readable storage medium embodying computer-executable code for accessing the database. The database provides, or can be used to calculate, a selectivity value for each of the words and optionally, word groups contained in or derived from the input text. Words and optionally, word groups having an above-threshold selectivity value are selected as descriptive terms from the input text.
