Example-based controlled translation

The first research on integrating controlled language data in an Example-Based Machine Translation (EBMT) system was published in [Gough & Way, 2003]. We improve on their sub-sentential alignment algorithm to populate the system’s databases with more than six times as many potentially useful fragments. Together with two simple novel improvements—correcting mistranslations in the lexicon, and allowing multiple translations in the lexicon—translation quality improves considerably when target language translations are constrained. We also develop the first EBMT system which attempts to filter the source language data using controlled language specifications. We provide detailed automatic and human evaluations of a number of experiments carried out to test the quality of the system. We observe that our system outperforms Logomedia in a number of tests. Finally, despite conflicting results from different automatic evaluation metrics, we observe a preference for controlling the source data rather than the target translations

Investigating the effects of controlled language on the reading and comprehension of machine translated texts: A mixed-methods approach

This study investigates whether the use of controlled language (CL) improves the readability and comprehension of technical support documentation produced by a statistical machine translation system. Readability is operationalised here as the extent to which a text can be easily read in terms of formal linguistic elements; while comprehensibility is defined as how easily a text’s content can be understood by the reader. A biphasic mixed-methods triangulation approach is taken, in which a number of quantitative and qualitative evaluation methods are combined. These include: eye tracking, automatic evaluation metrics (AEMs), retrospective interviews, human evaluations, memory recall testing, and readability indices. A further aim of the research is to investigate what, if any, correlations exist between the various metrics used, and to explore the cognitive framework of the evaluation process. The research finds that the use of CL input results in significantly higher scores for items recalled by participants, and for several of the eye tracking metrics: fixation count, fixation length, and regressions. However, the findings show slight insignificant increases for readability indices and human evaluations, and slight insignificant decreases for AEMs. Several significant correlations between the above metrics are identified as well as predictors of readability and comprehensibility

Use and Evaluation of Controlled Languages in Industrial Environments and Feasibility Study for the Implementation of Machine Translation

El presente trabajo de investigación se enmarca en los estudios de doctorado en traducción y la sociedad del conocimiento de la Universidad de Valencia y, en concreto, en la línea de investigación en tecnologías de la traducción, terminología y localización. En este sentido, esta disertación surge por la necesidad de establecer una metodología de investigación y ofrecer resultados empíricos sobre el desarrollo, implementación y evaluación de lenguajes controlados en la documentación técnica y su efecto tanto en los textos originales como en las traducciones de estos documentos. Así pues, el objetivo ha sido desarrollar una metodología para evaluar el impacto de los lenguajes controlados en la producción de documentación técnica dentro de contextos industriales y, más en concreto, en la elaboración de documentación técnica para el vehículo. El impacto se ha concretado en la mejora de la traducibilidad automática, un concepto que hemos discutido ampliamente en el capítulo 4, así como de la calidad de los textos meta.This research is part of the doctoral studies program "La traducción y la sociedad del conocimiento" at the University of Valencia. In particular the area of ​​research is translation technology, terminology and localisation. In this sense, this dissertation arises from the need to establish a research methodology and to provide empirical results on the development, implementation and evaluation of controlled languages ​​in the technical documentation and its effect on both original texts and the translations of these documents. Thus, the aim has been to develop a methodology to assess the impact of controlled languages ​​in the production of technical documentation in industrial contexts, and more specifically in the technical documentation for the vehicle. The impact has resulted in improved automatic translatability, a concept we have discussed at length in Chapter 4, as well as in the quality of the target texts
