Overview
  • 1. analysis of the user questions
  • (provided by ECNC and WWF)
  • a. clear cases
  • b. unclear cases and possible solutions
  • 2. Concepts and relations
  • 3. Discussion how to use knowledge discovery to
    answer complex questions

3
Analysis of the user questions
  • ?Total of 330 questions from WWF and ECNC.
  • ? Analysis of question type (what, where, who,
    when, how etc).
  • ? Words that express the relation that is asked
    for

4
Classification of questions
  • Finding Definitions, e.g.
  • What are the drivers?
  • What are ecosystem services?
  • Pin-Pointing Sources
  • Where are biodiversity hotspots?
  • Who is an expert on biodiversity?
  • Information Retrieval, e.g.
  • What is the current status of a specie?
  • What are the most recent countings of a certain
    specie?
  • Examples (of best practices), e.g.
  • Best practices of resource management in poor
    area's?
  • Are there examples of nature conservation and
    poverty elivation?
  • What are good examples of E.S.?
  • High level questions, e.g.
  • What are the key biodiversity indicators in a
    certain area?
  • What is the effect of climate change and species
    diversity?
  • What is the impact of declining bee populations
    on agricultural productivity?
  • Which rare and threatened species/ecosystems are
    people most dependent on for economic benefits?

Versions of KYOTO
  • KYOTO-1
  • extract all countings of species populations in
    regions for dates and periods
  • KYOTO-2
  • changes in numbers of species and sizes of
    populations, temporal relations and causal
    relations
  • KYOTO-3
  • to be determined....
