Classical approaches to learning word representation
In this section, we will discuss some of the classical approaches used for numerically representing words. These approaches mainly can be categorized into two classes: approaches that use external resources for representing words and approaches that do not. First, we will discuss WordNet—one of the most popular external resource-based approaches for representing words. Then we will proceed to more localized methods (that is, those that do not rely on external resources), such as one-hot encoding and Term Frequency-Inverse Document Frequency (TF-IDF).
