The European Semantic Technology Conference 2009 will take place in Vienna at the beginning of December 2009. Andreas Blumauer (Semantic Web Company) talked with Lyndon Nixon who is the program advisor of this conference:

SWC: In its own saying the European Semantic Technology Conference brings together the smartest minds in Semantic Technologies. What will be the highlights of this year’s conference?

There are many highlights this year! We have a full program of presentations, workshops, panels and a keynote by Susie Stephens from Johnson&Johnson. On top of this, the first day will see the first ever ESTC Innovation Seed Camp, where enterpreneurs and young start ups are invited to pitch their ideas to a panel of venture capitalists and there will be cash prizes! Besides the main program, an open demo space will continually offer new showcases of semantic technologies and products, while a networking zone gives attendees a relaxed space to make business away from the conference hectic. We will also be holding matchmaking sessions, where attendees can schedule one-to-one meetings with other attendees organized by a handy online tool. Finally, in line with ESTC’s focus on semantics and innovation – during the two days we will give participants the chance to check out two innovative conference tools: an electronic vCard exchange and the “Web Comparator”. So, too much to explain, but you can get full information on every aspect of the conference at its webpage www.estc2009.com.

SWC: How would you describe the state of the art in semantic technology business especially in Europe?

We are at a very exciting period in the enterprise uptake of semantic technologies, which can be seen in the growth in attendance at events such as ESTC. Semantic technologies are finally maturing and can be used away from toy examples in real, critical business processes. Technologies are being standardized and tools aligned to those standards, while progress in being made in supporting the sorts of extensions that businesses need (see OWL 2, or SPARQL 1.1). This year, the case studies and the business applications that will be presented are going to reflect that. We are still inside the early adopter phase in semantic uptake, with the critical mass of companies still checking out semantics at a research and prototyping level. However, the balance is shifting and enabling the technology transfer to real business projects is key; ESTC’s focus on direct contact between the technology vendors and the business clients – the networking zone, the open demo space, or the matchmaking sessions – is a reflection of the importance of an event such as ESTC to bring these two groups together.

SWC: One of the big issues at the moment is Linking Open Data. How do you perceive this development and how can you start?

Yes, Linked Open Data is an interesting development, making a significant amount of semantic data about a broad subject range available to everyone. I think it has real value in the research community where large data sources have been needed. For industry, I would say its value is less straight-forward: the data is not always so clean and care needs to be taken before building business applications on top of it. Clear guidelines on how to best make use of Linked Open Data by enterprises is needed. ESTC picks up on this in its program this year: we will have an expert panel precisely on this subject! Of course, leveraging the Linked Data Cloud in the enterprise is already a topic for many organisations – one of our paper sessions is on Linked Data and I am sure there will be plenty mentions of it elsewhere during the conference!

SWC: In recent years large IT-companies and system integrators have rather been playing around with semantic web technologies than identifying the semantic web
 as a market opportunity. Do you think that this situation has changed already?

I think a lot of these companies are being cautious – the Semantic Web was so hyped to industry in its first years that a certain level of cynicism grew. Now, that we have in my opinion very real and valuable tools and technologies built on semantics, the companies are being careful in how to present this to the market. There are already many very encouraging examples of semantics making inroads in key markets where data heterogeneity, integration, and management have become key issues: I think Health Care and Life Sciences is simply the market which is being most open about it (the ESTC keynote speaker Susie Stephens will also report on semantic technologies in this market). There are further examples we just don’t know about, because companies don’t want to let their competitors know, or mention that it is semantics which is being used.

SWC: Please add another statement which is important for you!

ESTC 2009 will be *the* meeting place in Europe this year for semantic technology vendors and users – don’t miss it!

There will be a series of events around the Semantic Web & Linked Data in Vienna and Graz at the end of this year. This is a comprehensive list of all of these events, which might help you to make a decision to come to Austria:

Linked Data Camp

• Linked Data Camp (Vienna, November 30 – December 1) with keynotes from Leigh Dodds (Talis) and Michael Hausenblas (DERI Galway) – Register here!
• Vienna Semantic Web Meetup (Vienna, November 30) as evening event of the Linked Data Camp
• SAMT 2009 – 4 th International Conference on Semantic and Digital Media Technologies (Graz, December 2-4) with keynote from Ricardo Baeza-Yates (Yahoo!)
• ESTC 2009 – 3 rd European Semantic Technology Conference (Vienna, December 2-3) with keynote from Susie Stephens (Johnson&Johnson)

The Jackson tribute might have been a flop for Vienna, but this is history! So, what are you waiting for – come & join the party!

Over the past few months we have seen an impressive increase in Semantic Web Meetups all over the world. More and more afficionados enjoy this informal and decentralized way of networking with the local community, gaining new inputs and impressions for projects and business ideas . On July 16, 2009 the first Semantic Web Meetup in Vienna takes place at headquarter of the Austrian Press Agency.

Join the community! It’s fun and free of charge!

Hello Monday! I am a bit tired today as I did not really have a weekend but spent it in a rather intellectually stimulating fashion, attending BarCamp Vienna held on the premises of HP in the 12th district. My head is still buzzing from all the input!

Originally, the plan had been to have a marketing-themed BarCamp, but thanks to the bottom-up approach towards scheduling typical for BarCamps, that didn’t quite come to pass (greatly appreciated also that this wasn’t enforced by the organizers, thank you!). There were two sessions in the ones that I attended that have relevance for the Social Semantic Web:

One was held by Alexander Kirk about the latest improvements in Factolex, a collaborative, micro-content encyclopedia based on facts; I hear that Factolex will receive further semantic enhancements in the near future, so I’ll write a longer blog post about it then. One feature Alex showed and which impressed me considerably was the distributed way in which one can add further facts to Factolex now: On any webpage, highlight a word or phrase (e.g. “President of the European commission”) and then click on the bookmarklet. Factolex is automatically going to check whether it knows the term already and either creates a new one or adds a fact to an existing term. The source will be added automatically – pretty nifty!

Another project that does not yet have a name and that is currently in stealth mode was presented by Christian Zeidler: Social Enhanced Search on del.icio.us. The project addresses a well known del.icio.us problem: You can search your bookmarks, i.e. search the tags and possibly definitions you might have added – yet all too often this only leads to the problem that your search query does not match the tags you once assigned. Being able to search the full text of the saved page would improve the scenario considerably – and this is exactly the approach Christian’s project takes.

To begin with, he built his own search index using Lucene, an open source, full-featured text search engine library written in Java. Of course it doesn’t crawl the whole web – just the pages you have added to your del.icio.us account. Instead of building one index for every user, Christian decided to have one large search index which also takes away the troubles of double indexation – the current index, based on 800 pages, doesn’t exceed a size of 3MB, which seems rather reasonable.

Apart from your own bookmarks, the plan is to also allow searching the bookmarks of your friends on del.icio.us, giving your search perspective. How many friends do you have on Facebook, how many on del.icio.us? It’s about half a dozen on del.icio.us for me, so I guess that “friendship” here really stands for particular topics and interests – this social perspective thing might actually work for enhanced searches, I think.

What other means are there to weight and rank search results? Somebody raised the issue of customization, i.e. let the user define which weight he’d like to give the results of which friend. I completely agree with Christian when he said he doesn’t believe people want customization, as conscious, user-initiated customization efforts are often (considered) too high. Instead, the system must learn from the data, e.g. prefer the results of friends whose results you use the most often.

Another useful feature that is already in place is that you can add any RSS feed to your search index as well – this is indeed very neat. And finally, in addition and as a point of reference, the prototype displayed the Lucene-based results in one column, and Yahoo! Search BOSS results in another column. Not surprisingly, the Search BOSS results were rather general, and the Lucene-based results rather specific – and that specificity is what you’d expect from searching your own bookmarks.
