Word frequency

Word frequency refers to how often a specific word appears within a given text or dataset. It helps analyze the importance, emphasis, or common themes present in the material. For example, in a news article, words like "economy" or "health" might occur frequently, indicating key topics. Measuring word frequency allows researchers and writers to identify main ideas, understand language patterns, and improve communication. It’s a basic tool in linguistics, data analysis, and natural language processing that reveals which words are most prominent and how language is used in different contexts.
