FrameNet is a lexical database that focuses on the relationships between words and the underlying concepts they represent. It organizes words into frames, which are structures that capture the meaning of a word in context. Each frame includes various roles that describe how different entities interact within that context. Developed at the International Computer Science Institute, FrameNet is used in natural language processing and linguistics to improve understanding of language. By providing detailed information about word meanings and their connections, it aids in tasks like machine translation and information retrieval.
