Question 3

For examples of how you can apply frames to other knowledge structures.

Answer 3

1) Semantic Networks
- Build a frame for each image object
- Can capture the object attributes and relationships with other objects
- To represent relationships, you can also just apply a variable as a filter that represent other frames.
2) Production Systems
- Working memory for Product Systems is really a frame.
- Can also be stored in Semantic memory and viewed as conceptual knowledge.
