Problems with Semantic Networks While semantic networks support default reasoning very well through the inheritance mechanism, they are not as flexible as logic when representing general statements. They add procedural attachment . A frame has slots and slots have values . A frame may be generic , i.e. it describes a class of objects. A frame may be an instance , i.e. it describes a particular object.
Frames can inherit properties from generic frames.
The value must satisfy the range help is triggered when the range demon is triggered and returns false. The following are not demons but demon-related facets in a slot. A Simple Frame Example Documentation for the frame language used in this example is available. The first reference to interpretation of this measure has the effect of dynamically adding a slot to the measure frame. Similarly, references to low , normal , and high dynamically add these as possible values.
