Overview: Word Vectors and Semantic Similarity

Overview: Word Vectors and Semantic Similarity

Let's see what we will learn in this section.

We'll cover the following...

Word vectors are handy tools and have been the hot topic of NLP for almost a decade. A word vector is basically a dense representation of a word. What's surprising about these vectors is that semantically similar words have similar word vectors. Word vectors are great for semantic similarity applications, such as calculating the similarity between ...
