Artificial Intelligence

Notes existentially measured variable whose value may rely on the agent. So we could create a
partitioned network as in Figure 9.8.

Fill in the blanks:
1. A ............................. is an attribute value pair in its simplest outline.
2. A ............................. is a value that a slot can take — could be a numeric, string (or any data
type) value or a pointer to a different slot.
3. A weak slot and filler structure does not consider the ............................. of the representation.
4. In ............................. method, the view that spreading activation out of two nodes and locating
their intersection locates relationships between objects.
5. ............................. Semantic Networks permit for propositions to be made without assurance
to truth.
6. ............................. Structures facilitates attribute values to be improved speedily where
declarations are indexed by the entities and binary predicates are indexed by first argument.

9.2 Frames

Frames can also be considered as an expansion to Semantic nets. Certainly it is not apparent
where the difference among a semantic net and a frame ends. Semantic nets initially we used to
symbolize labeled connections among objects. As tasks became more multifaceted the
representation requires to be more structured. A frame is a compilation of attributes or slots and
related values that portray some actual world entity. Frames on their own are not mainly useful
