Adding syntactic information to LSA

Much effort has been expended in the field of Natural Language Understanding in developing methods for deriving the syntactic structure of a text. It is still unclear, however, to what extent syntactic information actually matters for the representation of meaning. LSA (Latent Semantic Analysis) allows you to derive information about the meaning without paying attention even to the order of words within a sentence. This is consistent with the view that syntax plays a subordinate role for semantic processing of text. But LSA does not perform as well as humans do in discriminating meanings. Can syntax be the missing link that will help LSA? This paper seeks to address that question.
