I am using the Stanford coreNLP ( http://nlp.stanford.edu/software/corenlp.shtml ) in order to parse sentences and extract dependencies between the words.

I have managed to create the dependencies graph like in the example in the supplied link, but I don't know how to work with it. I can print the entire graph using the toString() method, but the problem I have is that the methods that search for certain words in the graph, such as getChildList, require an IndexedWord object as a parameter. Now, it is clear why they do because the nodes of the graph are of IndexedWord type, but it's not clear to me how I create such an object in order to search for a specific node.

For example: I want to find the children of the node that represents the word "problem" in my sentence. How I create an IndexWord object that represents the word "problem" so I can search for it in the graph?
