Topic Maps 2009 conference in Oslo by Jan Schreiber
I’ve spent the last two days at the Topic Maps 2009 conference in Oslo. The first day was a tutorial day. It was hard to decide between the Wandora-tutorial and the ZTM Topic Maps tutorial, but since I’d heard a lot about ZTM, but never had the time to give it a try, I decided to attend this full-day tutorial.
In contrast to many other tutorials that I attended at conferences, the goal was to get the ZTM platform up and running for all attendees - instead of limiting the tutorial to a presentation of the ZTM features.
It was quite time-consuming to install and configure Python and Zope on all machines, but after some hours we were able to import topic map into the system and create some topics and topic types manually in the administration interface. Arnar rounded up with a short introduction about how the template mechanism works. Once have the basic packages installed on your system, it should only take a couple of minutes to get a new site up and running - assumed that you have done this before a couple of times. ZTM Topic Maps currently only supports XTM 2.
Fortunately, I had a topic map in XTM 2 format at hand that I had created with the help of a Perl script from an Excel sheet some time ago. The topic map is a catalogue of all fennoscandinavian beetles with their scientific names (and PSI based on these), synonyms, redlist status, and the countries in which they appear. Additionally, the taxonomy includes suborders, families, subfamilies, genera, etc. For me, it was the first time that I look at the generated topic map. The Perl script still needs some tuning and some changes to the ontology, but in its current version it has about 8000 topics and 38000 associations. It was not problem to import the map into ZTM besides a little issue with the datatype of occurrences. More on that in a later post.
Today was filled with presentations and talk about various more or less Topic Maps related subjects. I’ll only give an overview of some of the presentations I attended:
In the keynote, Tommy Nordeng talked about why it is so difficult for people to share infomation. He presented the ambitious NDLA project, which aims at collecting and sharing lots of e-learning resources. Graham Moores talk was titled A Vision for a Topic Maps world. He gave a short summary of how and why Topic Maps is successful at a small and medium-sized (enterprise) scale. The main part of the talk he explained how to make Topic Maps a successful technology at large scale (= the Web). He presented a service for registration and discovery that is going to be launched next month by his company Networked Planet (btw, I had not seen their new web site before). In the next talk, Robert Engels, an active member of the Semantic Web community, presented the SeSam4 project which aims at providing semantic tools, methods and knowledge for owners of information systems. The objectives of the SeSam4 project include to develop open standards and tools, to verify semi-automatically generated ontologies, integration of content management systems, to improve methods for text mining and indexing, and to develop methods, models and procedures for semi-automatic generation of ontologies. One of the challenges that the project tries to solve is genuine interaction and communication between content creators, owners and consumers. He also talked a bit about use cases that are part of SeSam4: Tourism and construction. On the Topic Map side of the project plans are to choose either Wandora, tinyTim or TM++ as an underlying implementation, which is going to be decided soon. After a short break, Torstein Thorsen talked about FAST. Besides the title and a short comment at the end of the presentation, he did not mention Topic Maps. Instead, the talk was more a presentation of the different possibilities of how to implement search and faceted search with the FAST engine. At the end of the presentation, he showed us a prototype of a new search interface which was based on a drag and drop interface that lets the user search for songs in a music collection. After the lunch break, I went to see Jørgen Dalen talking about a Sharepoint and TMCore-based project. He claimed that 80% of the knowledge of a company only exists in the head of its employees, so a solution is needed to find people with the right competences in a large company. Bodil Kjelstrub from the University of Bergen spoke about the decisions behind the university’s new web site that is based on Topic Maps and implemented with ZTM Topic Maps. She presented some of the difficulties that arise when you try to create a solution for such a large institution. Stian Danenbarger introduced the concept of “modelldrevet søk” (model-driven search). He presented several ways to allow users to forfill their information needs. One of the examples was Freebase Parallax, a research prototype that uses the Freebase dataset. Another of the interfaces that he presented was the swedish site silobreaker, which offers search in a huge number of news, blog, research and multimedia sources. There is a lot more to tell from the conference, and this was only a short summary. I really enjoyed the conference, even more than the two years before. Maybe I’ll have time to write more later. Back to work.
