... language model we use for the experiments reported here is the same as the one used for other experiments reported in this paper. The results in Table 3 illustrate how the language model performs ... decoders have mostly relied on language models to select the proper word order among many possible choices when translating between two languages. In this paper, we argue that a lang...

The approach involves important advantages for both the student ... connected with the design of a universal error diagnosis for natural language sentences may only partially be seen as a motivation for this restriction.

... from a natural language ex- pression, E, into an equivalent expression, F, in an unambigous formal language. Typically, this for- mal language will be hand-crafted to enhance per- formance ... in NLU there is a fun- damental asymmetry between the natural language and the unambiguous formal language. Most no- tably, one formal language word may frequently cor- respond to...

... consistent within a document. Results Results for both settings are shown in Ta- ble 2. GTM models the latent topics at the document level, while LTM models each sentence as a separate document. To ... unseen for a given domain s, we are already performing an implicit form of smoothing (when computing the expected counts), since each docu- ment has a distribution over all topics, and...

... extensions for more complex situations. For example, longer doc- uments might benefit from an analysis on the para- graph level as well as the sentence and document levels. One possible model for this ... the document and sentences. For instance, in Pang and Lee (2004), y d would be the polarity of the document and y s i would indicate whether sentence s i is subjective or objective....

Introduction Many natural language applications are beginning to exploit some underlying structure of the lan- guage. Roukos (1996) and Jurafsky et al. (1995) use structure-based language...

We present results for ... of the form (v, n,p, n2), in which both the noun n and verb v are always known. We therefore must use any information in the unambiguous cases to resolve the ambiguous cases. A nat...
