Architecture of Assembly makes it easier to build complex services
Architecture of Assembly adds to Web of documents a layer of reusable services
Opportunities: -access to huge amounts of data useful for learning process; -analyze user generated content, e.g., to make estimations about their knowledge/competencies;  -finding/combining services and combining to train specific skills.
Trend: User-Centered Web
Trend: User-Centered Web focuses on the individual using these documents and services
Network of documents Network of people
Live Streams Facebook Friendfeed
Today: Silos
OpenID: decentralized single-sign-on mechanism OAUTH: information exchange between services OpenSocial: APIs for common functionality for social applications
Information about user: Attention Profiling Markup Language (APML) Location data: Google Gears, Firefox
Amazing amounts of data about user available Opportunity: use this data for personalization
Trend: Semantics
Access to data no longer problem
Access to data no longer problem Problematic: Find specific relevant piece of information
Access to data no longer problem Problematic: Find specific relevant piece of information Combine data
Semantic Web
Linked Open Data Initiative Datasets include Wikipedia, DBLP, RKB Explorer, CIA World Fact Book, OpenCyc, …
 
 
 
How to Get Semantics?
Entity Extraction ,[object Object]

Opportunities: - Semantic Content and Semantics for free enable amazing possibilities: improved quality of service, better  categorization, recommendation, automatic linking with other resources, etc.
Example: Totuba  Toolkit
- research workbench - bibliography manager - research network -  support while writing research papers

Related Topics: Web_2.0 in DBPedia ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Problems
Most services: English only Services can become unavailable
Lesson: To advance science, make research results available to other parties, as a Web service or open source.
Conclusion
Ground breaking services and data have now become basic commodity By building upon them, research in Technology-Enhanced Learning can tackle more meaningful problems
