4. The method of claim 3 wherein generating the semantic representation corresponding to the selected non-leaf node of the dependency structure comprises: obtaining a first syntactic vector corresponding to a first parent node of the selected non-leaf node; obtaining a second syntactic vector corresponding to a second parent node of the selected non-leaf node; generating the tensor by applying the tensor function to the first syntactic vector and the second syntactic vector; generating the first matrix by applying the first matrix function to the first syntactic vector and the second syntactic vector; generating the second matrix by applying the second matrix function to the first syntactic vector and the second syntactic vector; and generating the offset vector by applying the offset function to the first syntactic vector and the second syntactic vector.
