The document discusses the Pragmatic Web 4.0, which aims to connect intelligent agents and smart things in an ubiquitous computing environment. It describes how the Pragmatic Web builds upon the Semantic Web to incorporate understanding and interaction. Examples are given of pragmatic multimedia and applications that involve social tagging, context-aware media, and intelligent agents. The vision is of an open web platform supported by the W3C that enables smart content, devices, ecosystems and agent programming for the Pragmatic Web.

Syntax, Semantics, Pragmatics

Semantic Multimedia Web
Pragmatic Multimedia Web
W3C Open Web Platform
Open Web Platform for Ubiquitous
Pragmatic Web 4.0

3. Example: Traffic Light Situation Awareness
Syntax – Semantics - Pragmatics
 Syntax
 green (bottom); yellow; red
 Semantics
 green = go; …; red = stop
 Pragmatics
 If red and no traffic
then allowed to go

4. Example: Question-Answer Interaction
Syntax – Semantics - Pragmatics
 Syntax
 “What time is it?” (English)
 Semantics
 Question about current time (Meaning)
 Pragmatics
 An answer to the question is obligatory
(even if time is unknown) (Understanding
and Commitment)

5. The Semantic Web
„Make the Web understandable for machines“

7. Pragmatic Web
The Pragmatic Web consists of the tools, practices
and theories describing why and how people use
information. In contrast to the Syntactic Web and
Semantic Web the Pragmatic Web is not only about
form or meaning of information, but about interaction
which brings about e.g. understanding or
commitments.

9. Semantic Multimedia Web
(Knowledge and Meaning)
Data
 Semantic Analysis of Multimedia, e.g.,
 Knowledge assisted multimedia analysis
 Content-based multimedia analysis linked with natural
language/speech processing
 Semantic Retrieval of Multimedia, e.g.,




Information
Content
Semantic-driven multimedia indexing and retrieval
Semantic retrieval of 3D objects
Machine Learning and relevance feedback for finding semantics
Semantic-driven multimedia content adaptation and summarization
 Semantic Metadata Management of Multimedia, e.g.,
 Metadata management for multimedia
 Multimedia ontologies and infrastructures
 Semantic bridging multimedia and knowledge domains
Knowledge

10. Pragmatic Multimedia Web
(Understanding and Interaction)
 Inference and machine learning for semi-automatic annotation, e.g.,
 Assisted browsing in multimedia archives
 Device-specific access to and adaptation of multimedia
Semantic
Knowledge
 Semantic User Interfaces for Multimedia, e.g.,
 Interfaces and personalization for interaction with large multimedia repositories
 Semantic media annotation (manual, semi-automated, fully-automated)
 Semantics in Visualization and Computer Graphics, e.g.,




illustrative depiction and rendering
mapping meaning to presentation content
smart virtual environments
supporting knowledge discovery and interaction
 Pragmatic Web Applications of Semantic Multimedia, e.g.,




Social multimedia tagging and semantic annotation
Context, user, network and semantics-aware media engineering
Dynamic multimedia mash-ups
Smart multimedia (adaptive, situation-aware, reactive, proactive push)
Pragmatic
Interaction and
Understanding

11. A NEW WAVE of
TRANSFORMATIONS
W3C Open Web
Platform
(Source: Jeff Jaffe)
Just as the Web has
transformed
everything…
…It will transform
everything again

12. Vision: W3C Open Web Plattform
(Jeff Jaffe)
 Smart Content: Web pages and Web content are more interactive, intelligent
 HTML5 APIs, Semantic Web, Web data integration, …
 Smart TV: Multi-platform multi-media delivery and interaction.
 Video a first-class citizen, adaptive streaming, multi-device delivery and interaction
 Smart Devices and Smart Things: new mobile operating system and
numerous devices and things
 (handheld) intelligent devices are ubiquitous
 Real-time communications and reaction, multi-modal, multi-context interaction
 Smart Ecosystems: Web is a full-featured ecosystem
 Automated tools for social networking (privacy, security, identity), massive multiplayer
mobile gaming, ..
 Multimedia publishing ecosystems (smart content partially actively produced by consumers)
 End-user programmable intelligent Pragmatic Web agents
