  of Science
• UEP R.Jirouek, V.Svátek, et al.

Medical Guideline Technology

• UEP contributes in the areas of
• Designing a Medical Guideline Ontology
• Step-by-step mark-up of MG Documents
  (methodology, languages and tools)
• Modelling the compliance with MG, using the OCML
  Language Data Mining aspects
• Induction of Probabilistic Models from Patient
  Records (aiming at MG critiquing)

RAINBOW http//nb.vse.cz/svatek/rainbow

• Informal project undertaken at the UEP
  (Co-ordination V.Svátek, P.Berka, V.Sklenák)

• Aiming at a reusable architecture configurable
  for various tasks of WWW analysis and access

9
RAINBOW

• Automated extraction of meta-data based on shared
  ontology
• Labour division wrt. data type
• natural language, HTML tagging and generic page
  structure, frequencies of terms and concepts, URL
  addressing, link topology, explicit meta-data,
  image information
• Distributed skeletal planning

10
Analytical Reports Reusable Over the Web

• Co-ordinator J.Rauch
• Backround KDD research at the UEP
• partly within the Solomon European Network
  Project (IST-1999-11495)
• original KDD system LISP Miner mining
  (statistical) association rules, applications in
  finance and medicine
• organisation of PKDD99 (J.Rauch as PC Co-Chair)
  and Discovery Challenge 1999-2001 (P.Berka)

11
Analytical Reports Reusable Over the Web

• Need for reuse of both (template) KDD task
  settings and KDD results
• Envisaged tools
• KDD Ontology derived from CRISP-DM, combined with
  domain (e.g. medical) ontologies
• Analytical Reports as (semi-)automatically
  generated text documents enriched with logical
  formulae extracted from data
• knowledge (formulae) indexing for automated
  retrieval and reuse over the WWW
