Creating Knowledge out of Interlinked Data
Achievements1. Extension of the Web
with a data commons (currently amounting 25 Billion facts)
2. vibrant, global RTD community
3. Industrial uptake begins (e.g. BBC, Thomson Reuters, Eli Lilly)
4. Emerging governmental adoption in sight
5. Establishing Linked Data as a deployment path for the Semantic Web.
The emerging Web of Data achievements and challenges
Challenges1. Coherence: Relatively
few, expensively maintained links
2. Quality: partly low quality data and inconsistencies
3. Performance: Still substantial penalties compared to relational
4. Data consumption: large-scale processing, schema mapping and data fusion still in its infancy
5. Usability: Missing direct end-user tools and network effect
These issues are closely related and should ultimately lead to an ecosystem of interlinked knowledge!
• Web - a global, distributed platform for data, information and knowledge integration
• exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF

Creating Knowledge out of Interlinked Data

Web server
Problem: Try to search for these things on the current Web:•Apartments near German-Russian bilingual childcare in Leipzig.•ERP service providers with offices in Vienna and London.•Researchers working on multimedia topics in Eastern Europe.
Information is available on the Web, but opaque to current Web search.
Why Linked Open Data?
berlin.deHas everything about childcare in Berlin.
Immobilienscout.deKnows all about real estate offers in GermanyDB

Solution: complement text on Web pages with structured linked open data & intelligently combine/integrate such structured information from different sources:
Inter-linking/ Fusing
Classification/ Enrichment
Quality Analysis
Evolution / Repair
Search/ Browsing/ Exploration
Extraction
Storage/ Querying
Manual revision/ authoring

Challenges

Creating Knowledge out of Interlinked Data
Adaptive Semantic Authoring
semantic widget interface: allows the creation of small reusable interface components for domain-specific user interfaces (also for mobiles).
adaptive widget choreography: enables the automatic generation of user interfaces.
social networking interfaces: enable users to subscribe to arbitrary information adhering to certain semantically defined filter criteria.
WP5: Linked Data Visualization, Browsing and Authoring

Semantic pipes:
An engine and graphical
environment for general Web
Data transformations and Mashup.
Sig.ma:
A service and an end-user
application to access the
Web of Data as an integrated
information space.

Site Services: Site Search and Site Widgets
Widgets (right) provide relevant information, from Sindice, about the topic of the site.
Site search (below) provides a rich faceted-browsing functionality of the site’s widgets.
