Overview

• Knowledge: data representations supporting logical inferences and semantic queries
                      -> precision-oriented IR / document generation
  
  
• Storing knowledge and commands in documents
  
  
• Storing knowledge and commands in distributed scalable knowledge servers

Storing knowledge and commands in documents

• Knowledge-representation languages versus XML-based Metadata Languages
  
  
• Example of a knowledge modeling tool / private annotation tool / directed Web robot
  
  

Storing knowledge and commands
in distributed scalable knowledge servers

• A scalable cooperatively-built knowledge repository / public annotation server
  
  
• Distribution of knowledge on such servers
  
  

Scalable multi-authors KB

Precision and cooperation -> a unique KB
                               (1 consistent and organised semantic network)

• Scalable multi-user persistent object repository
  
  
• Algorithms for exploitating large-scale dynamic taxonomies
  
  
• Visualisation techniques (generation of views, aliases)
  
  
• Protocols to allow users to solve semantic conflicts
  
  
• Conventions for representing knowledge
  
  

Distributed KBs

Mirroring to speed searches, avoid query decomposition and inconsistency between KBS

• KBs mirroring each other
  
  
• General mirror KBs plus KBs specializing general KBs
