UnGroundNLP-2022: Uncertainty and Grounding in Language and Translation Modelling

  • Date: Friday, April 29, 2022
  • Venue: University of Helsinki, Siltavuorenpenger 1, Psychologicum, hall K170 (and online via zoom and/or gather-town)
  • Participation: Free of charge but registration is compulsory. Please fill in the online registration form. Registration deadlines: April 22 (for on-site participation) and April 27 (for remote participation)

The goal of this workshop is to bring together researchers who are interested in dealing with the inherent ambiguity of natural languages and researchers who work on learning meaning representations from multimodal and multilingual signals to improve language understanding in natural settings. We welcome contributions from the speech processing community, NLP research and people working with computer vision.

Co-located event

There will be another co-located event in language technology that will run just before the UnGroundNLP workshop (April 27-28). The CorCorDial project will run an international workshop on Corpus-Based and Computational Approaches to Linguistic Variation. That workshop is also free of charge and can be followed in place or remotely. Check out their program!

Local Information


Arriving by air

The Helsinki-Vantaa Airport is located some 17 km from Helsinki city centre and is easily reachable by train: a 30-40min train ride. The airport is of moderate size and quite efficiently run, but do allow 1-2 hours before departure for check-in and security. On arrival, you can expect to be out of the airport in 30 minutes after landing.

The easiest connection to the city center of Helsinki is by train. You can also look at other options of public transportation (search for the route from Lentoasema, Vantaa to Siltavuorenpenger 1 if you want to go to the University City Campus; the trip should take about half an hour and cost €5.50) or by taxi which takes a similar amount of time and costs about €50. More airport transportation options can be found on the Finnair website.

Local transportation

You can use the journey planner of HSL to find your way along the public transportation system of Helsinki. The department’s central location also allows walking to many destinations in the city.

All public transportation in the Helsinki metropolitan area uses the same ticket system. Single tickets can be purchased with your cell-phone (just download the app) or from ticket machines found on some of the stops.

Single tickets inside Helsinki cost 2,80 € when bought through the mobile app, 2,80 € when bought from a ticket machine. (Due to covid measures, tickets cannot be bought within the vehicles.) The ticket is valid for one hour from purchase and you can transfer freely from one line to another for that time. If you plan on using the public transport extensively, there are also day tickets available for periods of 1–7 days.

Venue and Map

The workshop will be held at Siltavuorenpenger 1, Psychologicum, hall K170. The building is hosted within the Central Campus of University of Helsinki, and is accessible via a 15 minute walk from the Helsinki Main Train Station (Helsingin Päärautieasema). Here you can find a screenshot of how to arrive form the main station:
