AbstractLocalization is a term mainly used in the software industry to designate the adaptation of products to meet local market needs. At the center of this process lies the translation of the most visible part of the product – the user interface – and the product documentation. Not surprisingly, the localization industry has therefore long been an extensive consumer of translation technology and a key contributor to its progress. Software products are typically released in recurrent cycles, with large amounts of content remaining unchanged or undergoing only minor modifications from one release to the next. In addition, software development cycles are short, forcing translation to start while the product is still undergoing changes, so that localized products can reach global markets in a timely fashion. These two aspects result in a heavy dependency on the efficient handling of translation updates. It is only natural that the software industry turned to software-based productivity tools to automate the recycling of translations (through translation memories) and to support the management of the translation workflow (through translation management systems). Machine translation is a relatively recent addition to the localization technology mix, and not yet as widely adopted as one would expect. Its initial use in the software industry was for more accessory content which is otherwise often left untranslated, e.g. product support articles and antivirus alerts with their short lifecycle. The expectation had however always been that MT could one day be deployed on the bulk of user interface and product documentation, due to the expected process efficiencies and cost savings. While MT is generally still not considered “good” enough to be used raw on this type of content, it has now become an integral part of translation productivity environments, thereby transforming translators into post-editors. The tutorial will provide an overview of current localization practices and challenges, with a special focus on the role of translation memory and translation management technologies. As a use case of the integration of MT in such an environment, we will then present the approach taken by Autodesk with its large set of Moses engines trained on custom data. Finally, we will explore typical scenarios in which machine translation is employed in the localization industry, using practical examples and data gathered in different productivity and usability tests.
