Representing Polysemy and Diachronic Lexico-Semantic Data on the Semantic Web

In this article we will outline two different vocabularies, both extensions of the lemon model, for representing diachronic lexico-semantic data on the Semantic Web. This is especially useful for repre-senting the evolution of scientific terminologies where many terms are polysemous and or imported from other languages. The first vocabulary, polyLemon , allows for the representation of data about polysemy; the second, lemonDIA the representation of meaning shift over time.
