Free Webinar: Linked Data for the Environmental Sector – Use Cases and Opportunities

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.

On June 13 this webinar 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!

Global Buildings Performance Network (GBPN)

GBPN_logo_rgb_72GBPN established the “Policy comparative tool on building stock data” together with a domain specific thesaurus used for a domain specific news aggregator.

Renewable Energy and Efficiency Partnership (REEEP)

logo_reeepAs one of the pioneers in the sector, REEEP has an extensive focus on the use of linked data for renewable energy and energy efficiency, facilitating that in various services, like an automatic annotation service, aggregated country data presented as fact sheets, a domain specific search engine, etc.

Austrian Geological Survey (GBA)

gbaThe main driving factor for institutions like the GBA to invest in thesaurus and taxonomy projects, is the increasing need for a uniform description of their data. The idea is that this enhances value and re-usability of their products for their stakeholders. Especially in the geo-spatial sector the INSPIRE directive of the European Parliament and Council gave a push in that direction. As a public authority, the GBA was legally called to implement the directive for its domain.

Linked (Open) Data has reached the European Publishing Industry – but is it the ‘Real Linked Data’ – a short review on the Publishers’ Forum 2013

Invited by Helmut von Berg, Director at Klopotek & Partner (Klopotek is THE European vendor for publishing production software) I had the chance to participate and speak at this years Publishers’ Forum 2013 at the Concorde Hotel in Berlin on 22nd to 23rd of April 2013.

Coming from the semantic web / linked (open) data community to this publishing industry event with about 320 participants (mainly decision makers) from small to huge publishers all across Europe made me really curious in the forefront of the Forum – what would be the most important issues for innovative publishing processes, what would be the hypes and hopes of a sector that is in the middle of a big change: coming from paper publishing straight into the world of our todays’ data economy?

And  then in Berlin, Monday morning – the big surprise: already the opening keynotes by David Worlock, Outsell, UK (Title of Talk: The Atomization of Everything) and Dan Pollock, Nature Publishing Group, UK (Title of Talk: Networked Publishing is Open for Business) mentioned topics as the Semantic Web, Linked (Open) Data and even RDF and Triple Stores – last but not least pointing out that the content of publishers needs to be atomized down to the ‘data level’ and then can to be used successfully for new and innovative business models to serve existing and future customers…

David Worlock ‘singing my song’ at the Publishers’ Forum 2013

As I participated in the European Data Forum 2013 (EDF2013) just a few days before the Publishers’ Forum my first thought was: WOW – publishers today have arrived in modern data economy (following already the data value chain)! And I enjoyed talking to David Worlock in the coffee break telling him my thoughts and that I will manage a workshop about ‘Enterprise Terminology as a basis for powerful semantic services for publishers’ in the afternoon that day (see slides on slideshare) and his answer was ‘Yes Martin, it seems that I was singing your song’.

The following 1.5 days of the Publishers’ Forum 2013 were full of presentations, workshops and discussions about innovative publishing processes, new business models for publishers and innovative approaches and services – full of terms that are well known by myself like: meta data management, semantics, contextualisation and very very often: Big Data and Linked (Open) Data…..and I listened very carefully to all of this – and at some point it was clear: this discussion needs to be evaluated more carefully – because many of talks and presentations were using the above mentioned terms, principles and technologies only as marketing buzz words – but taking a deeper look showed: there is no semantic web technology in place?!

Hey, Linked Data does NOT mean to establish something like a relation / a link between ‘an Author and a publication’ inside of a repository / a database – Linked (Open) Data is a well established and specified methodology using W3C semantic web standards:

Tim Berners-Lee outlined four principles of linked data in his Design Issues: Linked Data as follows:

  • Use URIs to denote things.
  • Use HTTP URIs so that these things can be referred to and looked up (“dereferenced”) by people and user agents.
  • Provide useful information about the thing when its URI is dereferenced, leveraging standards such as RDF*, SPARQL.
  • Include links to other related things (using their URIs) when publishing data on the Web.

Please read in more detail here:

As being a bit like an evangelist for Linked (Open) Data I think such a hype can be very dangerous for the publishing industry – because I see a very strong need for these companies to go for innovative content- and data management approaches very quickly to ensure competitiveness today as well as competitive advantage tomorrow – but not using the respective standards (means: only having the packaging and marketing brochures branded with it) cannot fulfill the hopes in the mid- and the long term!

Thereby I would like to point out here that ‘Linked Data’ seems not always to be ‘Linked Data’ – and I would like to strongly recommend to take a look at the well proven standards – and when selecting IT consultants and IT vendors (means: your IT partners – also a very interesting message taken home from the Forum: that publishers and IT vendors should co-operate more closely in the future in the form of sustainable partnerships) to ensure that these partners really have worked already and are working continuously with these standards and mechanisms!

WKD Use Case on Enterprise Terminologies

Btw. I had a great workshop on Monday afternoon together with Christian Dirschl from Wolters Kluwer Germany (WKD) discussing applications on top of enterprise terminologies (controlled vocabularies using real linked (open) data principles). And: The Semantic Web Company (SWC) is already a partner of the publisher WKD – and this partnership seems to become a more and more fruitful and sustainable one every day – using real linked (open) data…

Do you like Google’s Knowledge Graph?

Semantic Enterprise Search enters the second phase.

Finally the Knowledge Graph has arrived in Europe: What has been provided on google.com for the US-Market since May 2012, is now available also for most European countries. Search results are no longer only a list of documents (and advertisements) but also a mashup of facts, points of interest, events etc. referring to the search phrase.

For example, if the user is searching for ‘Wiener Philharmoniker’ (‘Vienna Philharmonic Orchestra’) a factbox including related searches is provided:

Do you like this rather new way of knowledge discovery? We do, except the fact that Google hasn´t properly explained to the audience which technology is behind the Knowledge Graph which is the Web of Linked Data aka the Semantic Web (Do you want to know more about the relationship between the Knowledge Graph and Linked Data? Click here).

But anyway, here are some benefits we can see, if search technologies make use of a ‘knowledge graph’, a ‘knowledge model’, a ‘thesaurus’ or generally spoken: Linked Data.

  • Facts around an object (or an entity) can be found nicely packed up to a dossier
  • Serendipity can be stimulated by ‘related searches’ which means: Users can discover the formely ‘unknown’ in a more comfortable way
  • Data from various sources can be pulled together to a mashup (e.g. ‘upcoming events’ could come from a different database than the basic facts of Vienna Philharmonic Orchestra)
  • Search phrases are well understood by the engine since they are based on concepts and not anymore on literals, e.g. if the user searches for ‘Red Bull Stratos’, also results for ‘Felix Baumgartner’ will be delivered
  • Search can be refined, e.g. if one searches for ‘Vienna’, a list of POIs will be displayed to refine the actual place the user is looking for

Now imagine you would have a search engine in your company’s intranet based on a knowledge graph which is about the enterprise you are working for.

Such an advanced search application would look like this:

  • Data streams and all kind of content from internal sources are nicely mashed with information from the web (e.g. from Twitter, Youtube etc.)
  • Search assistants are provided to help users to refine their information needs to make them more specific
  • Entities and their sub-concepts (e.g. subsidiaries of large companies or regions of countries) are nicely packed together to one dossier

The key question now is: “how to set up a customised knowledge graph for a certain company?”.

Corporate Semantic Web based applications can be realised on top of software platforms like PoolParty. They all have a customised knowledge graph in their core. This is always the basis for concept-based indexing of specialised content from a corporate intranet. The basic standard for this is SKOS which can be used together with advanced query languages like SPARQL. Such graphs can be used for semantic indexing but also to ask for relations like ‘is point-of-interest in’, ‘is event of’, ‘is related search for’ etc. This is the next-generation semantic search which help decision-makers, information professionals and all kind of knowledge workers to improve their work significantly.
One comfortable way to create customised knowledge graphs is to make use of Linked Data sources like Freebase (like Google does) or DBpedia. More details wanted? Take a look at the PoolParty approach for efficient knowledge modeling.
