The term that describes the representation of words changing based on context is contextual embeddings. This approach involves using models that consider the surrounding words or phrases to generate a unique representation for each instance of a word, allowing the meaning to shift according to the different contexts in which the word appears. For example, the word "bank" can refer to a financial institution or the side of a river, and contextual embeddings would produce different vector representations for each meaning depending on the accompanying words.

This ability to dynamically generate representations based on context enhances the model's understanding of semantics and improves its performance in various natural language processing tasks like sentiment analysis, translation, and more. Unlike static embeddings that provide a single representation for a word regardless of context, contextual embeddings offer a more nuanced understanding that aligns with how language is used in everyday communication.
