Abstract

This paper describes some experiments that used Genetic Algorithms (GAs) for looking for important word associations (phrases) in unstructured text documents obtained from the Internet in the area of a specialized medicine. GAs can evolve sets of word associations with assigned significance weights from the document categorization point of view (here two classes: relevant and irrelevant documents). The categorization was similarly reliable like the naïve Bayes method using just individual words; in addition, in this case GAs provided phrases consisting of one, two, or three words. The selected phrases were quite meaningful from the human point of view.
