1 Pragmatic Web 4.0 Towards an active and interactive Semantic Media Web Prof. Dr. Adrian Paschke Arbeitsgruppe Corporate Semantic Web (AG-CSW) Institut für Informatik, Freie Universität Berlin Fachtagung Semantische Technologien September 2013 HU Berlin

2 Agenda Syntax, Semantics, Pragmatics The Semantic Web The Pragmatic Web 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 Ontologies RDF Query Language Rules Semantic Web Information Model Standard Internet Technologies W3C Semantic Web Stack since 2007

6 Challenges for the Semantic Web Connectedness Intelligence / Wisdom Knowledge understanding principles Pragmatics Information / Content Understanding patterns Sematics Understanding relations Syntax Data Ontologies (Logic) Rules (Logic)??? (Machine Logic+ Human Logic) Understanding

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.

8 Machine Understanding Vision: Ubiquitous Pragmatic Web 4.0 Content Producer HTML XML RDF Smart Agents Consumer Semantic Web Pragmatic Web Pragmatic Agent Ecosystems Ubiquitous Pragmatic Web 4.0 Connects Intelligent Agents and Smart Things Social Semantic Web 3.0, Web of Services & Things, Corporate Semantic Web Connects People, Services and Things Ubiquitous autonomic Smart Services and Things Syntactic Web Semantic Web 2.0 Connects Knowledge World Wide Web 1.0 Connects Information Passive Active Desktop Monolithic Systems Era Desktop Computing Syntactic Web Semantic Web Pragmatic Web Ubiquitous Next Generation Agents and Social Connections

9 Semantic Multimedia Web (Knowledge and Meaning) 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., 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 Data Information Content 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 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) Semantic Knowledge 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

13 Content Producer HTML XML RDF Smart Agents Consumer Machine Understanding Ubiquitous Open Web Platform for the Pragmatic Web 4.0 Situation Aware Real-time Semantic Complex Event Processing Pragmatic Agent Ecosystems Semantic Web Pragmatic Web Massive Multi-player Web Gaming Ubiquitous Pragmatic Web 4.0 Connects Intelligent Agents and Smart Things Smart Web TV Social Semantic Web 3.0, Web of Services & Things, Corporate Semantic Web Connects People, Services and Things Ubiquitous autonomic Smart Services and Things Smart Content Syntactic Web Semantic Web 2.0 Connects Knowledge World Wide Web 1.0 Smart Content Connects Information Passive Active Desktop Monolithic Systems Era Desktop Computing Syntactic Web Semantic Web Pragmatic Web Ubiquitous Next Generation Agents and Social Connections
