In AI, a frame language is a technology used for knowledge representation. It organizes knowledge into frames, which are data structures that represent stereotyped situations or concepts, similar to classes in object-oriented programming. Each frame contains information such as properties (slots), constraints, and sometimes default values or procedural attachments for dynamic aspects. Frame languages facilitate the structuring of knowledge in a way that is conducive to reasoning and understanding by AI systems.

An example of a frame language is the FrameNet lexical database, which provides a detailed framework for representing the meaning of words in natural language. FrameNet organizes words into frames, each of which represents a specific concept or situation, such as ‘go to the store’ or ‘be angry’.
