Dependency tree development for answer extraction
<p>I am working on a Question Answering System . I am planning to use the Syntactic and semantic tree kernels for extracting features of sentences and to finally extract the correct answer from a list of documents . I want to know what all tools/APIs I can use for developing the dependency parse tree kernel for applying the method proposed by Moschitti (2005) . I am working with the Java Platform . </p>

<p>I have already found tools like Gate and SVM-light-TK 1.2 which do the same , but am not sure how to use them . If anyone has used them before or has information on how to use it and can suggest other tools , please help . Thanks in advance.</p>
