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
3
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.

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

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 don’t 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 won’t [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.
