Pangeanic’s development team gathered important input on advances on machine translation hybridation from leading academic at the
International Workshop on Using Linguistic Information for Hybrid Machine Translation (LIHMT-2011) and the practical Saturday session
ML4HMT (META NET WP2) in conjunction with DKFI. The sessions were geared for development and R&D personnel and those with a personal interest in making use of the best of research on MT and its different flavours to improve current state-of-the-art systems. Attendants and presenters were leading academics from the US, European Union and Japan involved in different MT areas. The theme was state-of-the-art developments in combinations (often involving Moses) and hybridation of rule-based approaches with statistics. Sessions dealt with combined approaches using syntax, grammatical information, rules and statistical systems. As different research teams are facing the same problems worldwide, some similar, some new some quite imaginative approaches are beginning to emerge, for example:

- Lemmatisation, annotation for morphologically-rich languages, for example Czech and Basque and even lesser resources in the case of the 2nd one.
- Syntax-based approaches and word re-ordering for very unrelated languages (such as Asian or Semitic languages into and out of European languages)
- Web-based annotation tools
- Hybridisation of techniques, starting from analysis at a morphological layer, then analytical layers, tectogrammatical layers, and then transfer, and on to synthesis to t-layers, a-layer and m-layer.
- Word disambiguation
- Mixture of rule-based and statistical approaches to improve predictability.
- Post-editing effort estimation for MT systems and with systems including no linguistic features or having some. Linguistic features are relevant for direct useful error detections and for automatic post-editing. But for sentence-level CE there are issues with sparsity and with representation (length bias).
- New metrics like VERTa, using linguistic knowledge organised in different levels (lexical, morphological, syntactic information and sentence semantics)
