A cognitive map consists of nodes representing concepts and ties indicating relationship between the concepts. In Carvalho section IV, the semantics is used in perspective of the presented model. Dagan's definition of semantic map is that it is a tree like structure branching from a main concept.
Also, the answer http://cs.stackexchange.com/questions/9800/are-semantic-networks-ontologies?rq=1 further adds to my confusion as to what is the significant different between cognitive map where nodes are concepts and semantic map where also the nodes are concepts.
I am unable to find significant difference between concept map and semantic map. Can somebody please explain in simple language? Thank you
