METIS-II was an EU-FET MT project running from October 2004 to September 2007, which aimed at translating free text input without resorting to parallel corpora. The idea was to use "basic" linguistic tools and representations and to link them with patterns and statistics from the monolingual target-language corpus. The METIS-II project has four partners, translating from their "home" languages Greek, Dutch, German, and Spanish into English. The paper outlines the basic ideas of the project, their implementation, the resources used, and the results obtained. It also gives examples of how METIS-II has continued beyond its lifetime and the original scope of the project. On the basis of the results and experiences obtained, we believe that the approach is promising and offers the potential for development in various directions.

This article investigates (a) whether register discrimination can successfully exploit linguistic information reflecting the evolution of a language (such as the diglossia phenomenon of the Modern Greek language) and (b) what kind of linguistic information and which statistical techniques may be employed to distinguish among individual styles within one register. Using clustering techniques and features reflecting the diglossia phenomenon, we have successfully discriminated registers in Modem Greek. However, diglossia information has not been shown sufficient to distinguish among individual styles within one register. Instead, a large number of linguistic features need to be studied with methods such as discriminant analysis in order to obtain a high degree of discrimination accuracy.
