Abstract. This article defines a Framework for Machine Translation Evaluation (FEMTI) which
relates the quality model used to evaluate a machine translation system to the purpose and context
of the system. Our proposal attempts to put together, into a coherent picture, previous attempts to
structure a domain characterised by overall complexity and local difficulties. In this article, we
first summarise these attempts, then present an overview of the ISO/IEC guidelines for software
evaluation (ISO/IEC 9126 and ISO/IEC 14598). As an application of these guidelines to machine
translation software, we introduce FEMTI, a framework that is made of two interrelated classifications
or taxonomies. The first classification enables evaluators to define an intended context of use, while
the links to the second classification generate a relevant quality model (quality characteristics and
metrics) for the respective context. The second classification provides definitions of various metrics
used by the community. Further on, as part of ongoing, long-term research, we explain how metrics
are analyzed, first from the general point of view of “meta-evaluation”, then focusing on examples.
Finally, we show how consensus towards the present framework is sought for, and how feedback
from the community is taken into account in the FEMTI life-cycle.

Recognition in the text of the need for constant evaluation of current practice has led to discussion and consideration of alternative methods of obtaining some projections. Throughout, the students are encouraged to evaluate their own practice. Learning and revision are enhanced by the use of photographs and helpful hints that appear with the more formal descriptions of technique. The NRPB and Royal College of Radiologists' recommendations on radiation protection and production of a diagnostic examination with the minimun radiation dose are also taken into account. All general techniques, including skull isocentrics, are covered, as well as techniques that are increasingly being undertaken by radiographers in these days of role extension, for example barium enemas and venograms.
