The paper addresses the integration architecture (I-concept) between a terrestrial technology—TETRA (TErrestrial Trunked Radio)—and satellite systems. This approach, that enhances and harmonises the features of both technologies, could provide an interesting contribution to the effectiveness of the International Mobile Telecommunications-Advanced (IMT-A) and, hence, to the 4G vision. TETRA can ...

We propose a number of refinements to the canonical approach to interactive translation prediction. By more permissive matching criteria, placing emphasis on matching the last word of the user prefix, and dealing with predictions to partially typed words, we observe gains in both word prediction accuracy (+5.4%) and letter prediction accuracy (+9.3%).

Accurate high-coverage translation is a vital component of reliable cross language information retrieval (CLIR) systems. This is particularly true for retrieval from archives such as Digital Libraries which are often specific to certain domains. While general machine translation (MT) has been shown to be effective for CLIR tasks in laboratory information retrieval evaluation tasks, it is genera...

Neural machine translation systems require large amounts of training data and resources. Even with this, the quality of the translations may be insufficient for some users or domains. In such cases, the output of the system must be revised by a human agent. This can be done in a post-editing stage or following an interactive machine translation protocol. We explore the incremental update of neu...

While Bourdieu’s theory of practice provides an ensemble of conceptual tools which analyze patterns of social life that are irreducible to the limiting view of individuals as free-acting agents, Genette’s paratextual theory offers the metalanguage necessary to account for the microcosm of paratext as a linguistic space. This study takes issue with unidirectional approaches to researching parate...

This work deals with the application of confidence measures within an interactivepredictive machine translation system in order to reduce human effort. If a small loss in translation quality can be tolerated for the sake of efficiency, user effort can be saved by interactively translating only those initial translations which the confidence measure classifies as incorrect. We apply confidence e...

State-of-the-art Machine Translation (MT) systems are still far from being perfect. An alternative is the so-called Interactive Machine Translation (IMT) framework. In this framework, the knowledge of a human translator is combined with a MT system. We present a new technique for IMT which is based on the generation of partial alignments at phrase-level. The proposed technique partially aligns ...

Whenever the quality provided by a machine translation system is not enough, a human expert is required to correct the sentences provided by the machine translation system. In such a setup, it is crucial that the system is able to learn from the errors that have already been corrected. In this paper, we analyse the applicability of discriminative ridge regression for learning the log-linear wei...
