TCS: a shell for content-based text categorization

The kind of application that the text categorization shell, TCS, can produce is characterized and how it meets its design goals are described, and examples of applications built with TCS are given.

Abstract

The kind of application that the text categorization shell, TCS, can produce is characterized. Many of its applications have great commercial value. The design goals for TCS are discussed, and other approaches to text categorization in the light of these goals are examined. The TCS and how it meets its design goals are described, and examples of applications built with TCS are given. A text-categorization application developed with TCS consists of the TCS run-time system and a rule base. The rule base defines what categories the application can assign to texts and contains rules that make the categorization decisions for particular texts. The data-driven nature of TCS allows it is to satisfy fully the requirements of ease of application development, portability to other applications and maintainability.>
