Study Notes

AI Techniques using Semantic Networks

Real-world knowledge is vast (Big Data) and disorganized (unstructured data).
Semantic Networks are a technique used in Artificial Intelligence to represent knowledge.
Semantic Networks use specialized nodes and links to represent relationships between objects.
Nodes: Represent objects, and are shaped as circles, ellipses, or rectangles.
Links: Represent relations between objects, represented as arrows pointing from one node to another.
Structural: Each link connects a tail node to a head node.
Semantic: Nodes and links represent specific entities within a specific application.
Procedural: Enables actions like constructing a node, creating a link, listing out-links from a node, listing the tail node from a link, and listing the label from a link.
Representational Adequacy: Semantic Networks must accurately and completely represent necessary data.
Effectiveness: Semantic Networks must allow for inference of new knowledge from existing knowledge and be computationally-friendly.
