Most information professionals already know: separation of content and presentation helps to manage and deliver complex information. This can only be done by using enriched structured content. Some call this intelligent content.
But why exactly is metadata per document (some call it “tagging”) not enough?
Here is a very brief slide-deck, which explains the difference between the traditional approach and the graph-based approach to develop not only a metadata layer seperated from the content layer, but also a knowledge layer on top of it.
Why semantic knowledge graphs matter
SEMANTiCS conference celebrated its 10th anniversary this September in Leipzig. And this year’s venue has been capable of opening a new age for the Semantic Web in Europe – a marketplace for the next generation of semantic technologies was born.
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 >>>
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!!
