Introduction to Frames and Scripts
Frames and scripts are knowledge representation schemes that organize knowledge into structured units. Frames represent objects or concepts along with their properties and relationships, while scripts represent stereotypical sequences of events or actions associated with particular situations.
Frame Representation
Frames consist of slots (attributes or properties) and fillers (values or instances) associated with those slots. Frames support inheritance, where properties and behaviours specified at higher levels of abstraction are inherited by lower-level instances.
Script Representation
Scripts represent stereotypical sequences of events or actions associated with particular situations or scenarios. They capture common patterns of behaviour and expectations in everyday activities.
Applications of Frames and Scripts
Frames and scripts have been used in various applications including natural language understanding, knowledge-based systems, cognitive modelling, and intelligent tutoring systems.
