Concept-Based Automatic Amharic Document Categorization

Along with the continuously growing volume of information resources, there is a growing interest toward better solutions for finding, filtering and organizing these resources. Automatic text categorization can play an important role in a wide variety of flexible, dynamic, and personalized information management tasks. The aim of this research work is to make use of concepts as a way of improving the categorization process for Amharic 1 documents. In recent years, ontology-based document categorization method is introduced to solve the problem of document classification. Previous works on keyword-based document categorization miss some important issues of considering semantic relationships between words. In order to resolve the existing problems, this research proposed a framework that automatically categorizes Amharic documents into predefined categories using concepts. The research shows that the use of concepts for an Amharic document categorizer results in 92.9% accuracy.
