Developed by quillian in 1968, as a model for human memory. semantic memory. models the “associations” between ideas and concepts that people maintain. semantic net is a labelled graph. objects, concepts, – nodes in graph represent or situations events; – arcs in graph represent relationships between these things.

Semantic networks are significant in natural language processing, knowledge representation, and information retrieval systems. they focus on capturing the context and meaning of words. it involves processing for tasks like sentiment analysis, text summarization, and question answering. moreover, semantic networks support machine reasoning. • one problem with semantic nets is lack of standard definitions for link names (is a, has a, etc.). • the oav triplet can be used to build a simplified 33 semantic net that characterizes the knowledge about the relationship between objects and their attributes (such as is a, has a, etc.) in a semantic net. −in artificial intelligence (ai), main focus is to store knowledge so that programs can process it and achieve human intelligence. there are different ways of representing knowledge e.g. −predicate logic, −semantic networks, −extended semantic net, −frames, −conceptual dependency etc.
