Natural Language Processing

Natural Language Processing (NLP) is a quickly growing field that is both challenging and rewarding. NLP takes valuable data that has traditionally been very difficult for machines to make sense of and turns it into information that can be used. This data can take the form of sentences, words, characters, text, and audio, to name a few. Why is this such a difficult task for machines? To answer that question, consider the following examples.

Recall the two sentences: it is what it is and is it what it is. These two sentences, though they have completely opposite semantic meanings, would have the exact same representations in this bag of words format. This is because they have the exact same words, just in a different order. So, you know that you need to use a sequential model to process this, but what else? There are several tools and techniques that have been developed to solve these problems. But before you get to that, you need to learn how to preprocess...
