SKOS as a Key Element in Enterprise Linked Data Strategies

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.

Linked Data and SKOS. Connecting the dots.

And here is a short overview over my talk I will give this June in San Francisco at this year´s SemTechBiz:

Knowledge organization systems like taxonomies or thesauri can benefit from linked data approaches and vice versa. In recent years SKOS became very popular in various industries due to its simplicity, not only for information retrieval purposes but also for knowledge modelling itself. For many organizations SKOS turned out to be the entry point to the Semantic Web.

A rather novel approach is to use SKOS as means for data integration. In combination with RDF mapping and linked data alignment technologies complex knowledge bases can be built to use them for the following application scenarios which we will demonstrate by using the PoolParty platform.
• How the creation of thesauri can become more efficient when built upon existing linked data sources
• how SKOS thesauri can be aligned with LOD sources and can be published as an LOD source itself
• How linked data mechanisms can be used to improve decentralized vocabulary management
• How SKOS and linked data alignment can be used for efficient schema mapping and value mapping
• How SKOS thesauri can be enriched with linked data to realise semantic search engines in a very efficient way
• How collaborative platforms like Sharepoint or Confluence can benefit from SKOS based knowledge models in combination with linked data

I hope to see you in San Francisco!

Do Controlled Vocabularies Matter?

The results of our survey about controlled vocabularies are published on Issuu.

The most interesting part of the results for me in a few words:

In August 2009 the W3C consortium announced the new SKOS standard – developed by the SWDWG – for bridging between the world of knowledge organization systems and the linked data community. Now, nearly two years after, it looks like this standard has well arrived. 48.7% stated that standards like SKOS are very important and 29.1% voted for “relevant”.

We also asked for other standards that are important for the participant’s daily work. From 250 nominations we decided to focus on those that had a score of at least 7. The big three are OWL, RDF and Dublin Core. Others were a variety of ISO terminologies, RSS, SPIN. Remarkable in this context is that SPARQL made it just to 5 mentions.

A couple of additional insights:
– most of our participants do have a clear awareness about controlled vocabularies and 85,4% are using them in their organization
– the bigger the organization the longer controlled vocabularies are used
– taxonomies and ontologies seem to be the preferred knowledge models
– semantic search, data integration and structure for content navigation are the main application areas for controlled vocabularies
– application areas like recommender systems, autocomplete suggestions and support for multilingual search are not seen as very relevant
– linked data is valued very positively as a future topic
– thesauri will support search engines in the near future to improve search results
– experience with controlled vocabularies is varying considerably among the branches
– there is a high awareness for standards like SKOS; the web-paradigm has entered the world of controlled vocabularies
– controlled vocabularies are no more locked in academic frames, they have also arrived in enterprise areas
