Disclosed are a computer-readable code, system and method for generating candidate novel concepts in one or more selected fields. The system operates to generate strings of terms composed of combinations of word and optionally, word-group terms that are descriptive of concept elements in such field(s), and uses a genetic algorithm to find one or more high fitness strings, based on the application of a fitness metric which quantifies, e.g., the number occurrence of pairs of terms in texts in a selected library of texts. The highest- score string or strings are then applied in a database search to identify one or more pairs of primary and secondary texts whose terms overlap with those of a high fitness string.

A method and apparatus is provided for extracting key terms from a data set, the method includes identifying a first set of one or more word groups of one or more word that occur more than once in the data set, and removing from this first set a second set of word groups that are sub-strings of longer word groups in the first set. The remaining word groups are key terms. Each word group is weighted according to its frequency of occurrence within the data set. The weighting of any word group may be increased by the frequency of any sub-string of words occurring in the second set and then dividing each weighting by the number of words in the word group. This weighting process operates to determine the order of occurrence of the word groups. Prefixes and suffixes are also removed from each word in the data set. This produces a neutral form of each word so that the weighting values are prefix and suffix independent.

Disclosed are a computer-readable code, system and method for combining texts to form novel combinations of texts related to a desired target concept, where the concept is represented in the form of a natural-language text or a list of descriptive word and/or word-group terms. The system operates to find primary and secondary groups of texts having highest term match scores with a first and second subset of terms in the concept, respectively. It then generates pairs of texts containing a text from each of the primary and secondary groups of database texts, and selects for presentation to the user, those pairs of texts having highest overlap scores as determined from one or more of (i) term overlap, (ii) term coverage, (iii) feature-specific cross-correlation, (iv) attribute-specific correlation, and (v) citation score of one or both texts in the pair.
