The challenges in implementing linked data technologies in enterprises are not limited to technical issues only. Projects like these deal also with organisational hurdles to be crossed, for instance the development of employee skills in the area of knowledge modelling and the implementation of a linked data strategy which foresees a cost-effective and sustainable infrastructure of high-quality and linked knowledge graphs. SKOS is able to play a key role in enterprise linked data strategies due to its relative simplicity in parallel with its ability to be mapped and extended by other controlled vocabularies, ontologies, entity extraction services and linked open data.
SKOS is at the intersection of three disciplines and their paradigms:
Whilst librarians, taxonomists, and specialists in the fields of text mining and entity extraction have started to embrace SKOS, especially ‘ontologists’ from artificial intelligence community still remain sceptical about the capabilities of SKOS.
With the latest release of PoolParty Thesaurus Server a full-blown ontology management facility has been introduced which can now be used to extend expressivity of SKOS knowledge models. For instance, SKOS concepts can become any other type of resource and by that schemas of additional relations and attributes can be applied to the concept.
PoolParty’s philosophy is to support users with Simple Knowledge Organization Systems (SKOS) first, to let them grow instantly by using various mechanisms like ontologies, text corpus analysis or linked data enrichment. All of them can nicely be combined. Users benefit from a step to step approach, not being bothered by an overarching approach from the very initial step. Learn more >>>
SEMANTiCS conference series will celebrate its 10th anniversary this year in September. SEMANTiCS (formerly known as I-Semantics) has had a long tradition in buidling bridges between practitioners and researchers in the areas of semantic web and linked data technologies. Therefore the SEMANTiCS consortium has developed new strucutures to further elaborate on this special character of this event series:
- Each conference session will combine talks from industry and research – those two interest groups won’t be seperated from each other anymore
- DBpedia community will be integrated deeply into SEMANTiCS conference: DBpedia has been the most successful activity in this area so far. A lot of industry-related projects has been built around this dataset. Therefore the 2nd meeting of the DBpedia association will be co-located with SEMANTiCS (taking place on September 3rd, also in Leipzig).
- Transfer-oriented side events and a centrally located market place will offer great opportunities to discuss about state-of-the-art technologies in the areas of Semantic Web standards based software and products.
The ‘document’ has been the most prominent metaphor to present information as well as being the predominant information carrier for ages. With the rise of the Semantic Web, information has been broken down to tiny pieces, which can be put in various contexts dynamically.
This principle can be applied to tackle some of the most important challenges faced by publishers nowadays: the most efficient reuse of media assets and personalisation of information services.
In a workshop, I will moderate at this year’s Publishers’ Forum (Berlin, May 5-6), you will find out, why semantic web principles & linked data technologies are the key for ‘Dynamic Semantic Publishing’. Attendees will learn from best practices and get an overview over state-of-the-art technologies.
I would be happy to meet you in Berlin!
2014 is only a couple of days old. I have some expectations and visions for the new year with regards to linked data and its next evolution steps.
- Smart data will receive a lot of attention: big data is the wave on which this certain topic surfs.
- Trust and provenance of data has been discussed for a while and has been mentioned frequently to be an important step for linked data to be accepted especially by enterprises. W3C’s PROV ontology was just a first step towards this direction. More specifications and implementations will follow this year.
- Automatic quality-checks for several types of linked data will become a matter of course (similar to test automation in software testing). One example is qSKOS which is provided as a web service for all people interested in controlled vocabularies like taxonomies or thesauri.
- The LOD cloud as we know it won’t be updated anymore: the periodical updates of the LOD cloud won’t happen anymore in 2014. The image would be much too big. Instead, several domains will generate their own LOD clouds, each of them with a couple of central hubs in the middle (see also: The LOD cloud is dead, long live the trusted LOD cloud). Those sub-hubs connected will represent the overall LOD cloud in the future. DBpedia will remain in the centre.
- Traditional database vendors will embrace RDF and SPARQL: MarkLogic Semantics and IBM’s DB2-RDF is just the beginning. It will be hard for them to deliver scalability and performance as good as ‘traditional’ RDF database providers like OpenLink Software or Ontotext can do.
- Linked Data “Killer applications” will be established: Automatic linking of structured and unstructured information based on RDF could become a killer application for Linked Data technologies. Take a look at two example applications in the areas of medicine and clean energy which make use of this principle: true semantic search will become possible (the two demos wont’t work properly behind the firewall due to some software libraries used by it).
- The year of semantic web standards: The Open Government Data movement will finally arrive at the point where standards based technologies like linked data become the obvious solution to the more or less chaotic collections of open data which have been accumulated in recent years.
- Enterprise Linked Data: More and more integrations of linked data technologies like Semantic SP into enterprise platforms like SharePoint will be available as products on the software market.
- SEMANTICS 2014 will take place in September in Germany and will be a great event. More to come soon.
- ISWC 2014 will take place in October at beautiful Lake Garda (Italy) and will be a great event, too.
- I am looking forward to meeting some of you once again, and also to meet some new linked data aficionados!!
Just recently I brought in a couple of arguments why LOD has to be more specific, traceable and most of all reliable (or trusted) before it will be used by enterprises.
Obviously this is also one of the core elements for a blueprint of a sustainable business model around Open Data.
Recently I talked about this topic together with my colleague Martin Kaltenböck from Semantic Web Company and Florian Bauer of REEEP in a webinar which was about Linked Data for the Environmental Sector. We discussed several use cases in which these principles are at least partly implemented.
Organizations working in the environmental sector most often act as intermediates between politics, economy and citizens. They are growing out of their role as plain content providers. To service the demands of their stakeholders they have to act also as data and tool providers for their respective communities.
This video introduces several good practice examples achieving data governance in using the linked open data paradigms. Together with a basic overview of the possibilities of linked open data you get an appealing picture of the new opportunities which are provided by these principles and technologies, also for your organisation!

Just recently, Pascal Hitzler has launched an interesting debate around the question whether there is ‘money in linked data, or not.’
Today I published a blog post in which I tried to point out why there is a lot of money in linked data. For users and for vendors.
In addition to this, here are some thoughts on Linked Data by Michael Gorriz, CIO of Daimler.
On slide #8 Mr. Gorriz states that ‘Linked Data drives the cultural change of the Enterprise’. Sic! Linked Data is more than just a technology. Cultural change is exactly what must happen in our days, otherwise we can shut down our sites pretty soon.
