Natural Language Processing Online Applications

I want to present an interesting link list with online and free to use interactive NLP related applications:

1. XLE Web Interface allows you to parse sentences of German, English, Norwegian, Welsh, Malagasy and Arabic. You'll get a very detailed parse tree and the functional structure of the sentence, for "This is madness!" you'd get:

2. Wortschatz Leipzig is a German application that crawls the web for a word and returns a detailed analysis of the word frequency, collocations and semantic relations. The word-graphs are most interesting, e.g. the graph for "Humbug" (German for "rubbish"):

3. WordNet is a large lexical database for English, e.g. "house" would show following interpretations:

4. Answerbus is a search engine like Google or Yahoo but with semantics! You can ask natural questions like "Who killed JFK?" and will (perhaps) get the answer "Oswald killed JFK". Perhaps... because the system actually sucks and you can easily outmaneuver it. Another search engine is START, which sucks too.

5. Wordfall is an awesome linguistic game! It's like Tetris but instead of blocks you have to match words to their constituents. Look:

6. Wortwarte is a German site about neologisms in the media. They are collected and sorted.

7. A cool German chatbot called ELBOT. It would definitely pass my Turing Test.

8. Think of a thing and 20Q will read your mind by asking 20 questions.

9. Machine Translation is one of the prime disciplines of NLP. Everyone knows Babelfish. It's not only a translator in the Hitchhiker's Guide but also an online translator like Google Translation.

10. TextCat is a language guesser based on an n-gram Perl script. Another and better one would be the XRCE language guesser.
