The Potential of Linked Data

Linked Data• Set of standards, principles for publishing, sharing

and interrelating structured knowledge• From data silos to a Web of Data• RDF as data model, SPARQL for querying• Ontologies to describe the semantics

Benefits of Linked Data in the Enterprise• Enterprise Data Integration: Semantically integrate and

interlink data scattered among different information systems

• Simplified publishing and sharing of data: Increase openness and accessibility of Enterprise Data

• Enrichment and contextualization through interlinking: Value add by linking to Linked Open Data

Everything as a Service

• Abstract from physical implementation details and location of resources

• Regardless of geographic or organizational separation of provider and consumer

• “In the cloud”• Web based• Virtualized• On-demand• Self-service• Scalable• Pay as you go

Data as a Service

Next generation of XaaS is centered around the power of data.

Data-as-a-Service

• Abstraction layer for data accessabstract the applications from the specific setup of the data management service (such as local vs. remote, federation, and distribution)

• Enabling automation of discovery, composition, and use of datasets

Next generation of XaaS is centered around the power of data.

“Like all members of the "as a Service” family, DaaS is based on the concept that the product, data in this case, can be provided on demand to the user regardless of geographic or organizational separation of provider and consumer.”

Data-as-a-Service – Beyond Data Access

• Data Markets: make it easy to find data from secondary data sources, consume or acquire the data in a usable – and often unified – format

• Online Visualization Services: allow users to upload data, make charts and visualizations and publish these to an online audience

• Data Publishing Solutions: allow data owners to publish their data collections and make them available to an online audience

• Data Aggregators: integrate, cleanse data from different sources to provide the aggregated data as a value added service

• BI / Analytics as a Service: provide higher level analytics functionality (statistical analysis), reporting, predictive analytics

Enabling Data Access:Virtualization of Data Sources

• Linked Data as abstraction layer for virtualized data access across data spaces

• Linked Data principles1. Use URIs as names for things 2. Use HTTP URIs so that people can look up those names. 3. When someone looks up a URI, provide useful information, using the

standards: RDF, SPARQL 4. Include links to other URIs, so that they can discover more things.

• Enables data portability across current data silos • Platform independent data access

8

Enabling Data Discovery:Metadata about Data Sets• Metadata about data sources essential for dynamic discovery• Access to data registered at global registries, e.g. ckan.org, data.gov, …• Based on metadata vocabularies (voID, DCAT)• Sort/filter data sets by topic, license, size and many more facets to identify

relevant data• Visually explore data sets

Enabling Data Composition:Federation of Virtualized Data Sources

Semantic Wiki + Widgets as Self-service Linked Data Frontend• Semantic Wiki for linking of

unstructured and structured data • Declarative specification of the UI

based on available pool of widgets and declarative wiki-based syntax

• Widgets have direct access to the DB• Type-based template mechanism

Information Workbench – Linked Data as a ServiceApplication Areas

Knowledge Management in the Life Sciences

Digital Libraries, Media and Content Management

Intelligent Data Center Management

Example:Conference Explorer

15

• „Linked-Data-a-Thon“: build an application that makes use of conference metadata and contextualizes data with external data sources in two weeks

• Realized with the Information Workbench

Data Sources• Conference Metadata (Linked Data)• Public bibliographic meta data• Social Networks:

• Twitter• Facebook• LinkedIn

• LinkedGeoData

Features• Conference schedule, timelines,

hot topics• Statistics and reports• Background information about

authors and publications• Link to social network profiles and

statistics

Example: A Cloud Portal for Access to Open Data with the Information Workbench

Goal• Collect meta data from global data markets (LOD Cloud,

WorldBank, CKAN, …)• Allow integrated search and ad hoc integration of data

sources from different repositories• Link data with private/internal data sources, if desired• Support semi-automated linking between data sets• Provide visualization, exploration, and analytics

functionality on top of integrated data sources

Realization• Currently running project with the Hasso Plattner Institute

(Potsdam, Germany)• Create local repository containing data market metadata• Use self-service technology to make services publicly

available + Information Workbench for analytics

... using the fluid Operations Technology Stack

Example: Linked Data in Pharma

Integ

Public Data Sources

Search, Interrogate and Reason

Capture and Augment Knowledge

Visualize, Analyze and Explore

Integrated data graph over all data sources

Private Data Sources

Main Use Cases

• Integrate data from company-internal data silos

• Augment company-internal data with Linked Open Data

• Collaborative knowledge management

• Support of internal processes (drug development)

Example: Dynamic Semantic Publishing

Information Workbench for DSP

• Collaborative authoring and linking of unstructured and structured semantic data

• Ontology and instance data management• DSP editorial workflows• Automation of content creation and

enrichment

Olympics 2012 requirements• A lot of output... Page per Athlete [10,000+], Page per country [200+],

Page per Discipline [400-500], Time coded, metadata annotated, on demand video, 58,000 hours of content

• Almost real time statistics and live event pages with too many web pages for too few journalists

Dynamic Semantic Publishing (DSP) architecture to automate content aggregation
