A semantic net is a type of knowledge representation that uses interconnected nodes and their relationships to establish meaning. There are several synonyms for this concept, including semantic network, conceptual graph, knowledge graph, and ontological network. Each of these terms represents a slightly different approach to organizing and understanding information. For example, a knowledge graph is typically focused on specific domains or topics, while an ontological network is concerned with defining the relationships between various concepts. Regardless of the specific synonym used, these concepts all share the goal of creating a structured way of representing and analyzing information in a meaningful way.
