A language modeling use case

Our goal is to build a language model using an RNN. Here's what that means. Let's say we have a sentence of m words. A language model allows us to predict the probability of observing the sentence (in a given dataset) as:

In words, the probability of a sentence is the product of probabilities of each word given the words that came before it. So, the probability of the sentence "Please let me know if you have any questions" would be the probability of "questions" given "Please let me know if you have any..." multiplied by the probability of "any" given "Please let me know if you have..." and so on.

How is that useful? Why is it important to assign a probability to the observation of a given sentence?

First, a model like this can be used as a scoring mechanism. A language model can be used to pick the most probable next word. Intuitively, the most probable next word is likely...
