general definitions.
According to WordNet, a synset or synonym set is
defined as a set of one or more synonyms that are
interchangeable in some context without changing
the truth value of the proposition.

relationship between them.

Dictionary : (randa-voo), A prearranged meeting place
Thesaurus : A meeting planned at a certain time and
place, Synonyms[coming together, meeting]
WordNet : A place where people meet,
“he was waiting for them at the rendezvous”,
