Semantic Web
• “bring structure to the meaningful
content of Web pages, creating an
environment where software agents
roaming from page to page can readily
carry out sophisticated tasks for users”
(Berners-Lee, 2001)

•
Meaningful?
Content?
Agents?
Tasks?
Semantic Web Elements
•
•
•
•
•
Expressing Meaning
Knowledge Representation
Ontologies
Agents
Evolution of Knowledge
Expressing Meaning
•
•
•
•
•
•
•
•
Documents for People
Information for Systems
Keywords and Their Meanings
Real World Rules
Real World Limitations
Extension of the Current Web
Decentralized
IA Applications
- Metainformation Definition
- Design Implementation
- Interface Research and Development
Knowledge Representation
•
•
•
•
•
•
•
Structured Collections of Information
Sets of Inference Rules
Automated Reasoning
Without Centralized Control
Massive Concurrency Coordination
Massive Complexity of Interpretations
IA Applications
- Adapting the Rules for Systems (Displays)
- Presenting Results and Actions
- XML and RDF
Ontologies
•
•
•
•
•
Consistency of Object Classification
Taxonomy of Object Uses
Navigation Scheme for Information Objects
(New) Applications to Utilize Data
IA Applications
-
Defining Ontologies
Updating (Correcting & Testing) Ontologies
Expressing Ontologies (IIC)
Defining Ontologies Use (Privacy++)
Agents
• Programs That Use Semantic Web Content
• More Automated as Systems and Content Support
Increases
• Digital Signatures
• Organized Services
• Ontology Exchanges
• Agent Interaction (Not)
• IA Applications
- Communicating Services
- Enabling Agents
Evolution of Knowledge
• Extend from Virtual to Physical World
-
Other Devices & Platforms
Composite Capability/Preference Profile
Complex Relationships and Interactions
Extend to Individuals (Characteristics)
Locations (Temporal)
IA Applications
• Designing New Interfaces and Content
• Organizing Mappings of Virtual and Physical
Interactions
• Coordinating the Semantic Web Design
Process
Semantic Web Challenges
• The Biggest Database Ever
• The ONLY Database?
- Individual/Group IM
- Individual/Group KM
• Decentralized or Partitioned?
- Concurrency? (Time)
- Currency? (Money)
• Knowledge Representation
- Computational Issues
- Cultural Issues
- Classification Issues
• IA becomes Transformed to Information Architecture
for People and Agents
• What about “People Readable” Information?
Semantic Web from 50K Feet
• “Full potential”
- For who?
- For what?
• Design Principles
-
Simplicity
Modularity
Decentralizaion
Tolerance
East transformation (least power language)
Test independent invention (others do the same)
Semantic Web Principles
• Everything is a link (URI)
- Permanence
- MIME types
• Everyone/thing is a Web server?
• Extended Control
- Individual/Group
• Form(at) and Content seperated
• Function is form(at)
• Translation – Transition
- Archives Conversion
- Forever Bootstrapping?
Network is work & design metaphor
- Hypertext
• Storage medium
• Access medium
- Collaboration
• Information
• People
- Network Metadata?
• Individual/Group
• Devices
• Situations
Knowledge Org Systems
• Isn’t this everything?
- “Information system”
- Database
• Commonality
- Tasks (applications)
- Terms (thesaurus)
- Technology (media, mediums)
• Formats
• Functions
Framework for Semantic Web KM
•

•
Maybe the best platform
The only platform?
Suspiciously like a RDBMS framework
We need abstractions
We need system designs
Conversion from existing systems
- Tools make the standards
- People choose the tools
RSS Readers

What is the best design?
Functions
Interfaces
Individual Users
Collaboration?
