Are semantic networks ontologies?

Problem
I struggle with few definitions in knowledge representation and seek credible help to distinguish between them. I have been searching on wikipedia and many websites for the difference between ontologies and semantic networks (not to be confused with semantic web). While the wikipedia page on semantic network never refer to ontologies, they seem extremely similar and have similar application in CS.
My guess is that semantic network are a type of ontology adapted for research on AI. However, I don't know the difference between both. So my question is simply:
Are semantic networks ontologies? If so, are they synonym? or what are the distinctions?

Solution
A semantic network is a graphic notation for representing knowledge in patterns of
interconnected nodes and arcs. It is one way for knowledge visualization and presentation. It was used firstly for for artificial intelligence and machine translation in computer science. What is common to all semantic networks is a declarative graphic representation that can be used either to represent knowledge or to support automated systems for reasoning about knowledge.
Ontology is a representation vocabulary, specialized to some domain or subject. It is a representation of a set of concepts within a domain and the relationships between those concepts. It is used to reason about the properties of that domain, and may be used to define the domain.
