Brief introduction to Linked Data © Semantic Web Company – http://www.semantic-web.at/ Putting the pieces together the agile way

Connecting the dots in a world of distributed systems
All the information to answer even complex questions is usually available
But: the information is scattered across different sources and not connected yet
Thus users/employees usually need a lot of time to connect the dots if it comes to rather complex tasks
We think that linked data is a proper approach to solve this common problem in a world of distributed systems

Linked Data: Graph-based data model based on open standards
Which kind of knowledge about certain things is relevant or not? Most often this can´t be described at the beginning of a project.
Linked Data is the agile way to handle data from different sources to serve various mind-sets & complex tasks.

Data integration – the traditional way © Semantic Web Company – http://www.semantic-web.at/ Data integration realised at application layer  Implicit conceptual model

Data integration – the linked data way © Semantic Web Company – http://www.semantic-web.at/ Integration on data level Application on top of explicit conceptual model

What is Linked Data?
Linked Data is most of all a data integration technology
Data is not necessarily stored as RDF
Linked Data technologies support data integration especially in dynamic & distributed environments
Large enterprises
Inter-Government organisations & NGOs
WWW
Linked Data (Semantic Web) technologies make conceptual models behind the data visible and explicit

3 flavours of linked data integration
Use Linked Data from the web
Publish Linked Open Data on the web
Make use of Linked Data principles internally

Putting the pieces together - the agile way
Graph-based data models can be grown the agile way.
Just like your business!

Create Linked Data - Some technologies I‘d like to mention
from databases: D2RQ, triplify, Virtuoso RDF Views, …
from spreadsheets, XML etc.: Google Refine, …
from HTML/microdata/RDFa: any23, …
from (unstructured) text: PoolParty Extractor, DBpedia Spotlight, …
by hand: PoolParty Thesaurus Manager, OntoWiki, …

Interlink: Linked Data Alignment
SILK : tool for discovering relationships between data items within different Linked Data sources
LIMES : a link discovery framework for the Web of Data.
LASSO : lookup service which helps to augment already existing, formalized knowledge with facts from the Linked Open Data (LOD) cloud

Searching for and querying over Linked Data
Sindice : Billion pieces of reusable information can already be found across hundreds of millions web pages which embed RDF and Microformats. Start consuming this data today with Sindice Data Web services. http://sindice.com/
LOD Lookup powered by Virtuoso : Lookup and search over the LOD cloud. http://lod.openlinksw.com/
Linked Life Data powered by OWLIM : LinkedLifeData is a platform for semantic data integration trough RDF warehousing and efficient reasoning that helps to resolve conflicts in the data. http://linkedlifedata.com/

Queries over a lot of sources - And with „a lot“ I mean „a lot“ © Semantic Web Company – http://www.semantic-web.at/
“ Which drugs are related to asthma that are linked to a curated molecular interaction in the literature where the protein is known to cause inflammatory response?”

Conclusion – What can Linked Data do for you?
make the meaning of data and information more explicit, visible and linkable
data integration from different sources in dynamic environments, incl. the WWW
generate search functionalities and reports on top of integrated data in a cost efficient way
use the web and web technologies to publish data and/or metadata to leverage the value of your assets
