Thanks Bill,

 

The subjective experience, or the human-factor aspect as you viewed it below, truly is different for everyone, and wherever a system has slippage for subjective variation, it happens, and variation gets into the data.  The thing that gets hard to work with is the belief that we should “make people do it right”.  The usual reaction of John Sowa’s “pointy-haired manager” prototype is to tighten up “the” way employees are told to interpret the data.  And sometimes that can actually work.  But only when “the official” feedback is provided nearly instantly after the action.  

 

I like strong typing because it helps me keep my programs working with instant feedback from the editor as I type small changes in source text.  Strong typing without an interactive, type-knowledgeable editor is much less effective.  If I don’t get a response until I hit compile, that slows down the feedback loop and makes me work too hard at simple details while keeping my grand design idea in mind.  Unless an ontology editor can be that quickly interactive, it won’t help the individual with the experience, IMHO.   

 

At minimum, an ontology editor should be capable of correcting my mistakes or at least suggesting among alternatives, based on my data, taken successfully in situations similar to mine.  Having to wait long for feedback is a stopper. 

 

By the same analysis, the data entry person (whether that person acts with skill and judgment, or just to earn a buck putting in text) has a subjective interpretation that has absolutely nothing to do with “the” ontology.  That subjective interpretation has an ontology all its own, which will have to be mapped to “the” ontology for correction to “the” objective reality.

Bravo, Rich – this is the first time I’ve heard anyone in any of these ontology/SUO forums stress so strongly the human-factor aspect of data semantics.   I’ve been trying to argue this point for years but to most CS-trained individuals it just falls on deaf ears.   I even have a nice little catchy name for the theory:  “Data Is Speech”.    As you suggest, there will be multiple ontologies (or whatever you want to call them) to formally represent different views of the word and they will need to be quickly adaptable to changing business requirements .  And the one significant missing and way way underserved ingredient is mapping and translation technology.

Ontologies, in my mind, offer a way to help sort, categorize and organize the chaos we've created.  We have to integrate the old with the new as we go forward, but this isn't as hard as it sounds.  SOA has given us the general technological approach, Semantics is adding a layer of rationalization on top.

 

Nicely stated - I'm still reading Karl Popper's Logic of Scientific Discovery, which is a dramatic reminder of the subjectivity we brush aside so easily.  Remember that the people who entered all that data into the database in the first place were each individuals with their own internal ontologies.  

 

The first problem in any database, even prior to formalizing “the” ontology or (more effectively, “some” ontologies) is to find ways to ascertain the meaning of data recorded there.  I described that in detail on my web site at:

www.englishlogickernel.com-Patent-7-209-923-B1.PDF

 

For example, when a Yes/No answer is mixed with 1/0, 2/1, T/F, True/False, and MIXTURES of the above (yes, T/1/F/0, 2/1/0 and other mixtures are possible since people are not consistent systems).  Attempts to force fit the answer into a very precise type of form (T/nil) leads to frustrated users, GUI programming errors, confused analysts and lots of data entry errors because most users don't have a real stake in most systems they deal with.  

 

For a few lucky enterprises, there may have been "the" enterprise ontology by designers who thought it might be useful.  In my experience, every enterprise system database evolves faster than the IT staff allocated to manage it.  There is too big a loop between the user with her needs and the developers who make changes.  

 

Meaning is in the eyes of the people who provide the data, and lots of that meaning is subject to human judgment, valuation diversity, and just plain old personal preferences.  Then there is the meaning in the perceptions of data analysts who try to make sense of the user data, or find patterns there, typically not having the original users available at the analyst's moment of investigation.  

 

But between the data entry person and the analyst, there may be lots of other users reading, perceiving, populating, editing, and otherwise in their own eyes "adding" meaning to the data by changing the original source data cells – all to meet their own individual ontologies.  So the typical enterprise database is full of classes and properties that shouldn't be there (given “the” ontology), but in fact they are.  Even worse, the variations are the main source of information in businesses looking for ways to improve profit, service, quality or other metrics.  The changes in data, the variations, contain the most information.  

 

Education and training of staff to enter data "the right way" is a hopeful tactic, but almost a waste of time, and users mostly still do what they think is good on the spur of the moment, just like the rest of us.  People work in our own conceptual ways, we deal with everyday situations in our own lexicon, grammar and thought processes, and "education" applied in that way is more appropriately called "indoctrination".  It tries to “fix” the users’ dynamic flow of structural information instead of adapting to that changing flow by processing a changing ontology with changing projected user ontologies.  

 

So the only conclusion I can reach is that "the" enterprise ontology, if singular, is a dynamic and variable entity that is no more fixed than any other specification to be implemented real soon now.  Forget about selecting ONE, and expect multiple ontologies; the transition sequencing from one to another (the periodic version update) is likely to become more manageable that way.  Expect ontologies to be iterative and plural, not fixed and singular. 

 

I think every user might some day have her own ontology.  Localizations and personalization can be used to adapt "the" ontology to a wider range of individual user needs as much as writing specialized queries in SQL which takes development labor.  

 

Surely a "semantic" application will influence the user's GUI behaviors in some dynamic way.  So if "the" ontology is dynamic, then "her" ontology must be getting calculated from "the" ontology either very quickly or very incrementally to meet GUI performance requirements.  

 

JMHO,
