Hi,

I'm forwarding Sunil's mail to the list -- I hope somebody out there
would provide some good answers to Sunil's and Surajit's queries.

Sunil, Surajit, are you members of the OTDev list already?

Micha, Barry, could you please make sure that Sunil and Surajit have
access to the OTDev list and its archives (if possible)?

Kind regards,
Vedrin

Hi Vedrin

Thanks for your thorough and quick responses. Following is a quick
update from our side...

Our team had been occupied predominantly on developing the MaxTox
prediction algorithm. And as the API has started emerging recently,
Surajit is working to conform to it.  A 1/1 discussion/Q&A point of
contact would be most helpful to make quick progress. Should Surajit
be talking with you?


A status update  is as follows:
Software to make Dictionaries ===> ready
Software to make models ===> R (random forests classification)
Software to make predictions ====> ready
Online version of Prediction ====> Work in progress (halfway done in JSP)
Online version of Prediction using OpenTox API ====> Just Started
Issues we are wrestling with:
1) Rapid evolution of API and quick turns on testing is presenting a
moving target.
2) Unclear about whether we should fit our algorithm into Blue Obelix
3) Should we host our software on our own servers or yours? What is
the recommended strategy?
4) There is no prior experience with RDF/OWL, we will need some help here.
5) Unable to make the R part of the code native to java as yet. Still
trying a few things. This hinders our ability to provide the API
interface.
6) We are using random forests classification algorithm. By the
Opentox model we should have access to this algorithm by an API. If
that is the case then we can easily use that for development of our
own model. However, as yet, it appears that no one has a algorithm/API
for random forests in opentox. How should we proceed in this regard?

Looking fwd to your gudiance.

Regards

Sunil

If there is some mechanism to give developers feedback/suggestions for
improvements or course corrections after testing of submiited services - it
would be helpful to us and bring quicker convergence.


Well, there are already several such mechanisms in place and in active use:
1) Developer's own bug (or issue) tracker, which has to be linked from
the webservice test instance description page:
http://www.opentox.org/dev/testing/testtoxservices
(most developers prefer this option so far)
2) OpenTox test results issue tracker:
http://www.opentox.org/dev/testing/testresults/issues
(this might be suitable for those who don't run their own issue tracker)
3) OT-Dev list, for any generic (e.g. API-related) issues.
4) Direct communication via e-mail or any other online collaboration
tool for issues which are service/implementation- specific and need
some more in depth discussion.
Do you have something else in mind?
Kind regards,
Vedrin
PS: Could you give us an update (preferably before tomorrow's meeting)
on SL's progress with software development?
