Here is the whole Stanford CoreNLP suite with visualisation output: http://nlp.stanford.edu:8080/corenlp/ http://nlp.stanford.edu:8080/corenlp/ It helps me greatly when it comes to interpreting the dependency structure. If you need an example sentence: "Stanford University is located in California. It is a great university." I also know that Microsoft Research has a demo online of their NLP tools: http://msrsplatdemo.cloudapp.net/ http://msrsplatdemo.cloudapp.net/ (Silverlight required) I don't think you can download the tools though, but they do offer to provide you with an API token to call their service from their cloud. Potential conflict of interest: I wrote parts of the CoreNLP visualiser. Edit: Added example sentence.
