formulate the multi-document summarization task using a Noisy-Channel model. This approach is novel . perspective by using the Noisy-Channel model; for example, Machine Translation (Brown et al., 1993), Question . Finally, in the decoding stage the goal is to combine P(S) and P(C|S) to obtain. P(S|C), which is the
Abstract—We show that optimal protocols for noisy channel coding of public or nication of classical information over noisy channels from two simpler Combining the latter results with those here implies a relation between the smooth relative and conditional entropies. Both of the primitive tasks used here are designed to.

A (?,?)-UNC realistic to assume that he cannot remove all noise from the channel, so such a case can be captured in the Combining Lemmas 4 and 2, gives directly the following result: Lemma 5. OT may be reduced to

We introduce a probabilistic noisy- channel model for question answering and we show how it can be exploited in the context of an end-to-end QA system. Our noisy-channel system outperforms a state- of-the-art rule-based QA system that uses similar resources. We also show that the model we propose is flexible enough
