Architecture of Assembly makes it easier to build

complex services


Architecture of Assemblyadds 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

FacebookFriendfeed


Today: Silos


OpenID: decentralized single-sign-on mechanism

OAUTH: informationexchange between services

OpenSocial: APIs for common functionality for social

applications


Information about user:

Attention ProfilingMarkup 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



Problematic:

Find specific relevant piece of information



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

The term "Web 2.0" is used to describe applications that distinguish themselves from previous generations of software by a number of principles. Existing work shows that Web 2.0 applications can be successfully exploited for technology-enhanced learning. However, in-depth analyses of the relationship between Web 2.0 technology on the one hand and teaching and learning on the other hand are still rare.

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


context-sensitive further reading

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
