Báo cáo khoa học: "HIDDEN UNDERSTANDING MODELS OF NATURAL LANGUAGE" ppt

... describe and evaluate hidden understanding models, a statistical learning approach to natural language understanding. Given a string of words, hidden understanding models determine the most likely ... states of each of the two models are unseen and must be inferred from the words. The problem of language understanding, then, is to recover the most likely meaning struct...

... achieves. As a result of the assumption of symmetry, both these models are ‘bag of words’ models and word order insensitive. Relaxing the assumption of sym- metry in the case of the simple additive ... function of the tensor product of u and v, then we obtain multi- plicative models: p = Cuv (4) where C is a tensor of rank 3, which projects the tensor product of u and...
