This is a simple English language tree parser that creates a parse tree of a given sentence and displays the tree graphically using D3.
It uses the treebank tokenizer from Natural Node and the POS tagger from pos-js to create tokens tagged with part-of-speech, and goes from there to try to determined a tree hierarchy.
It is still a work in progress and has a simple feedback mechanism for users to try out sentences and send feedback about any incorrectly parsed words.
