Semantic nets are a very important tool used in modern-day computer science, and there are several synonyms for this term. Certain individuals may refer to these as semantic grids or concept maps, while others may call them knowledge graphs or ontology. These terms are all interchangeable when referring to the same idea of a system of nodes and edges that represent objects and relationships between them. Such a system is often used to help computers understand natural language, making it easier for machines to perform complex tasks that would normally require human intuition. Whatever term is used, the importance of semantic nets in modern computer science cannot be overstated.
