Book excerpt: This volume draws attention to many specific challenges of multilingual processing within the European Union, especially after the recent successive enlargement. Most of the languages considered herein are not only ‘less resourced’ in terms of processing tools and training data, but also have features which are different from the well known international language pairs. The 16 contributions address specific problems and solutions for languages from south-eastern and central Europe in the context of multilingual communication, translation and information retrieval.
