Semantic Nets

• Quillian came up with Semantic Nets in 1969 as a way of describing human knowledge representation.
• One of the key properties of Semantic Nets is inheritence, which is also used in object oriented programming.
• Concepts are represented by nodes in a graph, and arcs are relationships.
• This is a powerful mechanism for representing complex knowledge bases.
• It's also a useful way of thinking about how people think.
• Finally, it's used in work on ontology.
