Web-Scale Natural Language Processing in Northern Europe

Research centers from across Northern Europe, the US-based Common Crawl Foundation, and the Nordic e-Infrastructure Collaboration (NeIC) work together to enable very large-scale computational experimentation in natural language processing.  This one-day workshop serves to kick off the collaboration, discuss community needs, and—through an open, popular-science session towards the end of the day—generate broader visibility.

Background and Motivation

Natural Langage Processing (NLP) is the inter-disciplinary branch of (among others) Computer Science and Linguistics that enables everyday technologies and services like, for example, automated translation (e.g. Google Translate), human–machine interaction in spoken language (e.g. Apple's Siri), or content recommendation and contextual advertisement (e.g. on on-line news sites).  As such, language-enabled technologies are of rapidly growing societal and commercial relevance.  In the past decade, NLP research has increasingly grown compute-intensive and data-driven—to a point that to date makes some (very large-scale) methodologies a ‘privilege’ of researchers who work in only the largest multi-national corporations.

In principle, NLP researchers in Northern Europe have available modern and comparatively extensive, public e-infrastructures, e.g. high-performance computing (HPC) and storage facilities.  However, there is no tradition of HPC utilization for NLP research yet, and candidate user communities have only recently begun to gain access to and learn to use national computing facilities.  Thus, this one-day meeting brings together researchers in natural language processing from across Northern Europe and other relevant stakeholders, to (a) facilitate ‘community building’ across national borders; (b) exchange experience reports and research visions; (c) kick off a collaboration with the Common Crawl Foundation; and (d) identify trans-national e-infrastructure community needs, as input to the Nordic e-Infrastructure Collaboration (NeIC).

Both the seminar and the workshop are held in seminar room Smalltalk, on the ground level (aka 1st floor) of the Department of Informatics (Ole Johan Dahls hus), right by the main entrance.

Participation

To sign up for the public seminar at the end of the day, please register on-line, using the link on the right-hand side (registration will inform catering, among other things).  For participation in the workshop, please just contact Stephan Oepen informally; in case you would like to present on your own research, there is still room in the programme.

Travel Support

With financial support from NeIC and the Norwegian WeSearch project, we can make available up to five travel stipends to (primarily earlier-stage) researchers who might otherwise be unable to participate.  Please contact Stephan Oepen for details about stipend availability and allocation.

Hands-On Follow-Up

Both Lisa and Stephen stay in Oslo for the day following the workshop, i.e. Tuesday, November 25, 2014.  The plan is to use the extra time to discuss technical details of the Common Crawl data, possible use patterns of the data for NLP research, candidate synchronization of web harvesting for the languages of Northern Europe, and the creation of a ‘mirror’ of (relevant parts of) the Common Crawl on NorStore facilities.  All workshop participants are welcome to stay overnight and use Tuesday for sub-group coordination and hands-on activities.  Stephan Oepen will be happy to assist in making accomodation arrangements.
