The vast market of free and opensource software has made the amount of available applications so big and ...

In this deliverable, we report futher development since T12 of the robust parsers at Cambridge/Sussex, Stuttgart, and Pisa. TEL:: +39 50 560481

For each word sense, typical contexts of use were acquired and structured as "paradigmatic structures" on the basis of distributional criteria. Word sense disambiguation is modelled as a process of "paradigm extension" grounded on the acquired paradigmatic structures. The technique, already applied with success to a number of Natural Language Processing (NLP) applications, is currently under extensive test for word sense disambiguation: preliminary results look promising.

An explanation can mainly be found in the inherent difficulty of defining a formal setting for a rigorous evaluation of the power of analogy, which has ...
