Meronymy is a semantic relation between a part and a whole. For example, “wheel” is a meronym of “car”.
Holonymy is a semantic relation between a whole and a part. For example, “car” is a holonym of “wheel”.

Semantic networks are a way of representing the meaning of words and phrases in a computer. They are made up of nodes and edges. The nodes represent concepts, and the edges represent the semantic relations between them.
Meronymy, holonymy, and hyponymy are all important semantic relations that can be used to represent the meaning of words and phrases in a semantic network.
