Hack4Europe! – Europeana hackathon roadshow, June 2011

Europeana is a multilingual digital collection containing more than 15 millions resources that lets you explore Europe’s history from ancient times to the modern day. Europeana API services are web services allowing search and display of Europeana collections in your website and applications. The folks at Europeana have been actively promoting the experimentation with their APIs by organizing ‘hackathons’ – workshops for cultural informatics hackers where new ideas and discussed and implemented.

Some examples of the outputs of the previous hackathon can be found here. Hack4Europe is the most recent of these dissemination activities:

Hack4Europe! is a series of hack days organised by the Europeana Foundation and its partners Collections Trust, Museu Picasso, Poznan Supercomputing and Networking Center and Swedish National Heritage Board. The hackathon roadshow will be held simultaneously in 4 locations (London, Barcelona, Poznan and Stockholm) in the week 6 – 12 June and will provide an exciting environment to explore the potential of open cultural data for social and economic growth in Europe.

Each hackathon will bring together up to 30 developers from the hosting country and the surrounding area. They will have access to the diverse and rich Europeana collections containing over 18 million records, Europeana Search API (incl. a test key and technical documentation) and Europeana Linked Open Data Pilot datasets which currently comprise about 3 million Europeana records available under a CC0 license.

There are four hackathons coming up, so if you’re interested make sure you sign up quickly:

Reintegrating the Human(ities): Reflections on Cultural Heritage and the Semantic Web at the British Museum

I spent most of yesterday attending a workday on Cultural Heritage and the Semantic Web at the British Museum. Unfortunately I had to miss the final two papers and the closing panel, so I’m not in a position to offer an overall summary. But certain themes and common notes kept arising in each of the six talks I did manage to catch — and these are worth commenting on in themselves, because they mark, to my mind, a new (and, I think, messier and more interesting) direction for the Semantic Web than that most frequently outlined in the past.

Knowledge Representation workshop @ CCH

A couple of months ago or so we started a Knowledge Representation workshop with a few enthusiastic colleagues at CCH. The basic idea is to take a broad perspective on the various topics related to KR, and then focus on the digital humanities so to see how these approaches and technologies can be best applied to our domain.

What is a knowledge representation? Although knowledge representation is one of the central and in some ways most familiar concepts in AI, the most fundamental question about it–What is it?–has rarely been answered directly. Numerous papers have lobbied for one or another variety of representation, other papers have argued for various properties a representation should have, while still others have focused on properties that are important to the notion of representation in general. [continue reading]

Other than that, the scope of the workshop will remain deliberately unspecified so that we are allowed to decide session after session what topics should be discussed. I’ll be posting the slides and research produced in the context of the workshop on this blog, so maybe also others will be interested in taking part in this (either physically or electronically!). if you do, please get in touch 🙂

The slides from our first meeting can be found online on slideshare:

Among the TOPICS that emerged as needing more reflection:

  • the ontoclean methodology: need more examples and rationale for each of the meta-principles
  • top level ontologies: is it sensible to aim for having only one? If not, what does a ‘relativist’ position entail?
  • the cyc project: why didn’t it conquer the world? where were its flaws?
  • ontologizing ‘humanities’ data: is the subject domain posing specific challenges, or not?
  • implementing an ontology: what are the languages/frameworks available? (we mentioned the possibility of inviting an external speaker on this topic, some time in the future)
