By classifying the documents, the search is then limited to only those documents that related to a particular category. Text classification is the process of classifying documents based on their content into predefined set of categories. Many classification systems that based on rules generation approach have been adopted for text classification. The classification rules that generated from these classifiers conducted directly from the characteristics of training documents. Which will be limited to a certain categories and has unequal number of the generated classification rules per category. In this paper, an automatic text classification system based on the genetic algorithm classifier has been developed. The genetic algorithm classifier generates a predefined …
