Conclusion

• Semantic nets are about concepts (nodes) and their associations (arcs).
• Thus they are associative memory.
• They are a concise way of representing information, and inheritence is clearly useful as the software engineers have taken it over.
• Rule based systems can implement Semantic Nets, but a lot of other types of systems can take advantage of them.
• Do we represent concepts this way? Try the 10 questions game.
