| Paola,
Here is the link to a recent PhD thesis by J. van Diggelen entitled Achieving Semantic Interoperability in Multi-agent Systems: A Dialogue-based Approach [pdf]
Also, on his publications page, there are a couple presentations and a software download for Anemone, the implementation of the thesis.
