Professor Constantin Orasan
About
Biography
I am Professor of Language and Translation Technologies at the Centre of Translation Studies, University of Surrey. Before starting this role, I was Reader in Computational Linguistics at the University of Wolverhampton, UK, and the deputy head of the Research Group in Computational Linguistics at the same university. I have received my BSc in computer science at Babeș-Bolyai University, Cluj-Napoca, Romania and was awarded my PhD from the University of Wolverhampton.
I have over 20 years experience of working in the fields of (applied) Natural Language Processing (NLP), Artificial Intelligence and Machine Learning for language processing. My research interests are largely focused on facilitating information access and include translation technology, sentiment analysis, question answering, text summarisation, anaphora and coreference resolution, building, annotation and exploitation of corpora.
I recently coordinated the EXPERT project, an extremely successful Initial Training Network (ITN) funded under the People Programme of the Seventh Framework Programme (FP7) of the European Community which trained the next generation of world-class researchers in the field of data-driven translation technology. In addition to coordinating this project between nine partners across both academia and industry, I was actively involved in the training of the Early Stage Researchers (ESRs) appointed in the project and, in collaboration with these ESRs, I carried out research on translation memories and quality estimation for machine translation. I continue researching these topics.
I was also the deputy coordinator of the FIRST project, a project which developed language technologies for making texts more accessible to people with autism. In addition to managing a consortium of nine partners from academia, industry and heath care organisations, I also carried out research on text simplification and contributed to the development of a powerful editor which can be used by carers of people with autism to make texts more accessible for these people.
In the past In the past, I was the Local Course Coordinator of the Erasmus Mundus programme on Technology for Translation and Interpretation and the Erasmus Mundus International Masters in Natural Language Processing and Human Language Technology, and the scientist in charge for the University of Wolverhampton in two European projects QALL-ME and MESSAGE. I also worked as a research fellow on the CAST project.
I love programming and in my spare time I contribute to some open source projects and have my own GitHub repository.

Teaching
MODULES TAUGHT THIS ACADEMIC YEAR
TRAM500: Introduction to computational thinking for translators (module leader)
The purpose of this module is to enable students to acquire basic and intermediate concepts of computer science and programming, and to learn how to apply them to problems related to translation-related tasks such as glossary creation, error analysis, automatic substitution. The programming language used in the class is Python.
TRAM502: Smart technologies for translators (module leader)
The module explores the main theoretical and practical aspects of smart technologies for translation, with emphasis on how to use methods from Natural Language Processing and Corpus Linguistics to help translators. The purpose of this module is to enable students to understand the challenges faced when using computers to process text automatically or when they need to process speech as an input.
TRAM449: Interpreting and technologies
This module introduces students to the principles and practical implications of using technologies in the interpreting profession. In this module, I contributed with lectures on machine translation and speech to speech translation.
TRAM495: Principles and challenges of translation and interpreting
This module provides students with a systematic framework for understanding the key concepts in Translation and Interpreting Studies and how they relate and apply to everyday professional practice. In this module, I contributed with lectures on human-computer interaction for translators and interpreters and quality in translation.
