How Do You Categorize Based On Text Content?

Question

How does one automatically find categories for text based on content?

Answer 1

1. Read Data Mining: Practical Machine Learning Tools and Techniques - Ian H. Witten, Eibe Frank
2. Use Weka or Orange

Answer 2

I would encourage you to look at the text classification libraries bundled with the Natural Language Toolkit. Even if you're not familiar with Python I think you'll find the API rather intuitive. There are many good examples in the NLTK Book and the people on the mailing list are quite helpful as well.
