Any papers we can learn your method from?

Dear All,
      What Prof. John has recommended, I do agree.
I think before I say anything, I should introduce myself (because this is
the first time I am writing to this forum). I am a Senior Research Fellow
of DRTC, ISI (Documentation Research and Training Centre, Indian
Statistical Institute), Bangalore, India which was established by Prof. S.
R. Ranganathan (the Father of Library Science in India).

We are now actively working on Ontology and faceted classification area.
As a part of our research work we have developed ontology(s) based upon
Prof. Ranganathan's Principles and system. Among them one is,
Institutional Ontology which is capable of giving us quite satisfactory
results. But still it is not the right time to claim that we have reached
to the end product. We are working. Hope we will be able to come out with
a good result.
