At first glance, synonymy and antonymy can be seen as binary relations between words.
based on empirical results 2 Edmundson defined synonymy and antonymy as ternary relations in order to consider the multiple senses of the words, as follows: xS i y ≡ x synonym of y according to sense i xA i y ≡ x antonym of y according to sense i Note that the senses of the words are represented in the relationship rather than in the words themselves.
