Summary
This paper reports on the VarDial 2017 evaluation campaign, held with the fourth VarDial workshop at EACL 2017. It grew out of the earlier DSL shared tasks and broadened them into four separate challenges:
- DSL: telling apart closely related languages and national varieties in short news excerpts.
- ADI: identifying Arabic dialects from speech transcripts plus acoustic features.
- GDI: classifying Swiss German dialect transcripts, with no audio provided.
- CLP: dependency parsing of a target language that has no treebank, using treebanks of a closely related source language.
For DSL, the organizers built DSLCC v4.0 following the method of Tan et al. Teams could compete in a closed track (organizer data only) or an open track (any data), with up to three runs in each.
Overall, 26 teams registered, 19 submitted runs, and 15 wrote system papers. All CLP entries relied on annotation projection rather than model transfer. CUNI won CLP clearly on LAS, and for Slovak the two best systems even beat the fully supervised upper bound.
The campaign matters because it offers shared datasets and a common evaluation setup for low-resource, closely related language varieties. This makes it directly relevant to Slavic and other neighbouring-language NLP work.
Key points
- DSLCC v4.0 covers 14 languages and varieties, including Bosnian/Croatian/Serbian, Malay/Indonesian, Persian/Dari, two French, two Portuguese, and three Spanish varieties.
- Each variety has 22,000 excerpts: 18k for training, 2k for development, and 2k for testing. This gives about 8.6M training tokens and roughly 0.55M test tokens.
- ADI covers Egyptian, Gulf, Levantine, North-African, and MSA. GDI covers the Basel, Bern, Lucerne, and Zurich dialect areas.
- CLP language pairs were Croatian←Slovenian, Slovak←Czech, and Norwegian←Danish/Swedish. Only three teams took part: CUNI, Helsinki-CLP, and tubasfs.
- CUNI's LAS scores were 60.70 for Croatian, 70.21 for Norwegian, and 78.12 for Slovak. For Croatian and Norwegian, cross-lingual parsing still trails supervised parsing by about 8 LAS points.
