Ontology Engineering (03)
Dear Matthew and Ali, (04)
I agree with the importance of Matthew's questions. I also agree with Ali's
answers. But I'd like to make different suggestions. (05)

Yes, but I don't believe that the overwhelming majority of developers will ever
understand ontologies -- either well or poorly. (07)

I agree. But I believe that we need *radically* different tools.
The SMEs should do their work in *their* preferred languages and notations.
They should *never* be asked to learn anybody else's notations, conventions, or
interfaces. (09)

I agree. But the solution is to get the information from the same sources and
tools that the SMEs themselves read, write, and use. (011)
> Formal, computational ontologies in general are not well developed...
> Bindings into alternative reasoning algorithms and evaluation

Those bindings should be made to the tools and resources the SMEs are already
using to do their job. Any necessary ontologies should
*help* the SMEs to do their work better and faster. (013)

I agree. But those are symptoms of not having the right tools. (015)

More symptoms of inadequate tools. (017)
Fundamental principle: Ontology tools should *reduce* the expense by enabling
SMEs to accomplish more in less time. The ontologies should be a *by-product*
of the SMEs' normal work. (018)
Recommendation: The ontology summit should devote more attention to
cutting-edge research than to incremental improvements on inadequate tools.
Some suggestions: (019)
1. See the slides and publications by the Aristo Project at AI2:
http://www.allenai.org/TemplateGeneric.aspx?contentId=12 (020)
2. The IBM Watson project is also doing research on deriving
knowledge from the same kinds of resources as AI2. (021)
3. Tom Mitchell at Carnegie Mellon developed the Never-Ending Language
Learner (NELL): http://rtw.ml.cmu.edu/rtw/index.php . Or see (022)
http://wamc.org/post/dr-tom-mitchell-carnegie-mellon-university-language-learning-computer (023)
4. For the past few years, I've mentioned Cyc as an important
project that is doing important research with the world's
largest formal ontology. (024)
5. And from time to time, I cite the VivoMind work. For example,
http://www.jfsowa.com/talks/goal7.pdf (025)
I won't claim that these projects will solve all the problems tomorrow.
But I believe that tools based on some combination of these methods will solve
the problems raised by Matthew's questions. They'll get better results faster
than trying to "educate" developers about ontology. (026)
