Community Data Evaluation
  • Progress in many scientific communities depends
    on complementary
  • experimental and theoretical development.
  • These communities require high quality data to
    evaluate findings.
  • - Our primary community is the Atmospheric
    Community .
  • The Motivation
  • Study how to transition from today's ad-hoc
    process practises
  • Sustainable process of
  • Gathering, community evaluation and sharing data
    models between scientists
  • Minimising changes to proven working practises
    of the scientist
  • Operate within world-wide co-laboratories

4
Capturing Provenance Data
  • Provenance is captured in three forms namely
    Inline (during the experiment execution), pre-hoc
    and post-hoc, before and after the experiment.
  • Broadly speaking there are two categories for
    capturing provenance data in e-Science projects
  • System oriented There are usually tightly
    coupled with the workflow paradigm and seek to
    automatically capture provenance.
  • User oriented Adopting key practises from the
    scientific approach and use domain specific
    scientific terminologies.
  • In this research we seek to develop a user
    oriented approach and reconcile with the system
    orientation to automate process provenance
    capture. Specifically capturing inline
    annotation.

Current Evaluation Processes for the MCM

Envisioned Evaluation Processes
7
ELN Process
8
ELN Screenshots
  • Prompts displayed when changing the chemical
    mechanism
  • Editing a reaction
  • Adding a new reaction

9
Evaluation Methodology
  • In-depth interviews with members of the
    atmospheric chemistry model group at Leeds,
    covering
  • Demonstration of the prototype
  • User testing of the prototype
  • Discussion of scenarios involving the use of the
    prototype.
  • Analysis
  • Interviews recorded and transcribed
  • Analysed using techniques from grounded theory

10
Evaluation
  • Barriers to adoption
  • Effort required at modelling time for provenance
    capture
  • in your lab book you can write down what ever
    you want but with an ELN it is going to take
    time to go through the different protocol steps.
  • When asked if they would use an ELN requiring a
    similar amount of user input to the prototype the
    response was positive
  • Yeah, I think it would be a good thing. I dont
    think it is too much extra work.
  • Rather than viewing the prompts for user
    annotation as interruption to their normal work
    the user recognised the value of being prompted
  • is a good way to do it because otherwise you
    wont record the provenance.

Conclusion
  • Outlined the Community Data Evaluation using a
    Semantically Enhanced Modelling Process and the
    ELN.
  • The work is focused on a user-oriented approach
    using domain specific scientific terminologies.
  • Showed the community evaluation vision.
  • Discussed the ELN evaluation method.
  • Future work
  • Carry out further investigation into the
    atmospheric chemistry community.
  • Look into other community that would benefit from
    this work such as Geomagnetism.
