SerenAProject vision

“The vision of the SerenA project is to transformresearch processes by proactively creating surprisingconnection opportunities. We will deliver noveltechnologies, methods and evaluation techniques forsupporting serendipitous interactions in the researcharena.”


Introductions

I Dev team


Aims of the workshop

I Introduce the basic concepts of the Semantic Web.

I Creating a semantic user profile.

I Introduce and explore Linked Open Data.

I To connect people with pertinent and interesting ideas

I . . . and to each other through pathways of related areas

The web!

The Semantic Web


The Semantic WebPrinciples

I Building blocks are very simple!

I Describing resources with Resource Description Framework

Subject the resource being describedProperty denotes traits or aspects of a resource

Object the associated resource

e.g.

<Joe Bloggs> age "40"<Joe Bloggs> friend <Harry Hill><Hary Hill> location <Edinburgh>

The Semantic WebTerminology



I Unique Resource Identifier’s represent thingshttp://www.serena.ac.uk/users/robstewart

I The same thing can have many URIs.

I The same thing can have different names in different datasources.http://www.macs.hw.ac.uk/~rs46/robhttps://www.twitter.com/!#/robstewartUKhttp://www.serena.ac.uk/users/robstewart

Linked Open DataWhat is it?

Linked Open Data is real datapublished according to Semantic Webprinciples.



Europeana: example LOD service provider.

An EU funded project to produce a multi-lingual onlinecollection of millions of digitised items from Europeanmuseums, libraries, archives and multi-media collections.

DBpediaWhat is it

I Extracts structured information from Wikipedia

I Links Wikipedia to other semantic datasets on the web

I Allows Wikipedia information to be used in new andinteresting ways


Linked Open DataHow do I find it?

The Data Hub is a community-maintained catalogue of datasets,managed by the Open Knowledge Foundation.

http://thedatahub.org/

Of these, the current 327 datasets making up the LOD cloud arelisted here:

http://thedatahub.org/group/lodcloud


http://thedatahub.org/

http://thedatahub.org/group/lodcloud

Linked Open Data5* linked data

* Information available on the web under open license

** Information as structured data (e.g. spreadsheets)

*** Non-proprietary formats (e.g. CSV not Excel)

**** URI identification allowing other dataset to link toyour data

***** Data linked to other dataset to provide context

I Linked Open Data: OSM data as RDF – the canonicalreference for all things spatial.

I More than 1 billion resourcesI 100 million ”ways” from OSMI 20 billion triples

Linked Open Data

LOD makes it possible to make connections across heterogeneousdata sources.

I Adds value to the data.

I Makes data more accessible and meaningful.


Linked Open DataVisualizations


LOD VisualizationsLodLive

I Visual navigation of RDF resources

I Users can easily navigate between datasets

I Can interlink LOD resources with RDF files on the web
