A thesaurus is a reference book containing a classified list of synonyms (and sometimes definitions). N-grams are simple to compute, and can perform well when combined with a stoplist of PoS filter, but is useful for fixed phrases only, and does require modification due to closed-class words.

Figure 1-2 shows a depiction of these tasks based on their relative difficulty in terms of developing comprehensive solutions. Let’s start by taking a look at some popular applications you use in everyday life that have some form of NLP as a major component.

Thus, they can be stacked one over another to form a matrix or 2D array of dimension n ✕ d, where n is the number of words in the sentence and d is the size of the word vectors. This matrix can now be treated similar to an image and can be modeled by a CNN. The main advantage CNNs have is their ability to look at a group of words together using a context window. For example, we are doing sentiment classification, and we get a sentence like, “I like this movie very much!
