Text Categorization: Implementation

This chapter is concerned with the implementation of prototype version of text categorization system in Java. The simplest machine learning algorithm, one nearest neighbor, is adopted as an approach to text categorization. We present the system architecture, source code, and demonstration of executing the system. We mention points for upgrading the system which is implemented in this chapter. In this chapter, we implement the text categorization system in Java and demonstrate it to provide guide of implementing its real version.
