Knorpora is a modified version of the Knoppix 3.3 Live CD for students of corpus-based computational linguistics.
Like Knoppix, the Knorpora CD allows you to run a fully operational Debian/Linux operating system from the CD-ROM drive, without installing anything on the computer.
The Knorpora edition of Knoppix contains programs and data files that should be of interest to computational linguistics students (WordNet, the Natural Language Toolkit, taggers, etc.)
When you launch Knorpora on your computer, you can immediately start learning how to use a UNIX-like operating system while at the same time experimenting with the kind of UNIX-command-line-based NLP tools that make UNIX the ideal operating system for NLP work.
Even if you already work with UNIX, Knorpora may give you the chance to try some interesting software before you install it.
