Semantic Readings Discussion
System Install and Configure (1)

2. 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?

3. Semantic Web Elements Expressing Meaning Knowledge Representation
Ontologies
Agents
Evolution of Knowledge

4. 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

5. 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

6. 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++)

7. 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

8. 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

9. 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?

10. 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)

11. 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?

12. Network is work & design metaphor
Hypertext
Storage medium
Access medium
Collaboration
Information
People
Network Metadata?
Individual/Group
Devices
Situations

13. Knowledge Org Systems Isn’t this everything? Commonality Formats
“Information system”
Database
Commonality
Tasks (applications)
Terms (thesaurus)
Technology (media, mediums)
Formats
Functions

14. 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

15. RSS Readers What is the best design? Functions Interfaces
Individual Users
Collaboration?
