What This Document Is
This document is a focused exploration of techniques used to automatically categorize information found on the World Wide Web. Specifically, it delves into the field of web page classification – the process of assigning web pages to predefined groups based on their content and characteristics. It examines both subject-based and genre-based classification approaches, providing a foundational understanding of the systems and methods employed in this area of computer science. This is a chapter excerpt from a more comprehensive work on web mining and the Semantic Web.
Why This Document Matters
