Hello all, I am interested in performing Triplet Extraction.
For that, I need to traverse the parse tree. I know how to use the ChunkMe, however I am not sure how to use the Parser so that I can create a tree to traverse it. Ideally, I want to obtain the subject, predicate and object. To find the subject I need to search in the NP subtree selecting the first descendent of NP that is a Noun via breadth first search. To find the predicate I will search the VP subtree, the deepest verb descendent on that tree will give the predicate. Now for the object(s) they can be in 3 different subtrees. PP, NP and ADJ. In NP and PP they will be the first noun while on the ADJ we need to locate the first adjective. Therefore, what I need to learn is how to create the parser and the main tree so that I can navigate the subtrees. Thanks for the help, Carlos.
