5. Digital library management Web as document repository Distributed resources and users Hard questions for digital libraries –“Who disagrees?” –“Where did this idea come from?”

6. Hypertext argumentation research Clearer thinking Modelling as craft Schema complexity trade-off Interface design is crucial

7. Shared modeling space Virtual communities sharesIssuesWith Distributed users Who might use it? What is the motive? What is the cost? What is the benefit? Reducing costs –Better modelling tools –Templates to get beginners started Increasing benefits –Services

13. Discourse ontology links Representing interpretation Uses/applies/ isEnabledBy Links are more stable than objects Links represent the mechanism of debates Links have properties –Type –Polarity –Weight

14. Relations: Discourse Ontology

15. Untyped hyperlinks Discourse ontology links Citations improvesOn No semantics limits automatic processing Limits services

16. Uses/applies/ isEnabledBy Search of link structure Path matching Text search improvesOn Text gives topic word search Hypertext & citation gives search of untyped links Typed links guide semantic search through path- matching

18. Filtering and interrogating the network Once the network becomes large we need more than browsing Neighbourhood (semantic citations) Supports/Contrast Lineage
