Computational lexicons represent an area where a pressing need is felt for the provision of basic large-scale resources which must be reusable, interchangeable, shareable and also integrable in a multilingual environment. In terms of costs and effort it is expensive to produce such resources in detail. In the construction of large-scale resources and in the definition of annotation strategies, reusability is an essential requisite to pursue (Calzolari, 1994).
If we want to produce and exchange natural language resources which are effectively shareable, and possibly usable by the same set of basic tools, with results of processing which are really comparable and integrable, we should aim at designing and producing these resources according to a common set of consensual and broadly agreed specifications, i.e. standards (Calzolari & Zampolli, 1994).
