How do you incorporate domain knowledge and external resources in text classification?
Text classification is a common task in natural language processing (NLP) that involves assigning a label to a piece of text based on its content. For example, you might want to classify news articles into different categories, such as politics, sports, or entertainment. However, text classification is not always straightforward, as different texts may have different styles, tones, and contexts.
