Gary,

I think this paper aims to articulate knowledge modeling needs of scholars studying cultures and the history of ideas. Historicity cannot be an afterthought and must accommodate the notion that concepts and categories evolve, including category theorys. 

The development of UMLS in the life sciences provides an example. This started as key words, grew to curated taxonomies, then to a synthesis across 80 or so vocabularies and ontologies in a megathesaurus.  Over time, it was found that concepts e.g. of a disease, may persist  through time and across different terminology, but also the concept as well as the names by which it is known may evolve through time and further research.  So, they changed their practices and how they modeled things.

Much of the history of IT has been preoccupied with record keeping and current accounts. Data has been shoved into box cars called fields, and retrieved from them and manipulated algorithmically with fixed logic. That is, system knowledge is fixed at design time and doesn't change, until the next version of the system is published, with the next version of knowledge encoded into it. During operation IT systems haven't learned, they just follow rote procedures.  

Historically, there are many good reasons for the information and algorithm centric approach. The study of culture, however, calls for a richer palette both for knowledge representation, and for reasoning processes that encompass different axiologies, epistemologies, and research methodologies.  

Description logic plus some overarching notions about logic unification (at the FOL level, I believe) is about where we are with the semantic web. We can expose data.  But, todays semantic web standards do not provide an adequate foundation for the sorts of cultural researches, and knowledge-based computing that this author and other scholars envision, and are engaged in already.

On the paper by Veitman, or at least the summary there are enough vagaries to inspire a debate equal to that of the John Cage silence/hole.

Here is a link to a paper by Kim Veltman: 

 

 

This paper argues that the computing community (and semantic web crowd in particular) has been overly fixated on first order logic and has failed thus far to produce a semantic web that is suitable for culture. The abstract reads:

 

Today’s semantic web deals with meaning in a very restricted sense and offers static 

solutions. This is adequate for many scientific, technical purposes and for business 

transactions requiring machine-to-machine communication, but does not answer the 

needs of culture. Science, technology and business are concerned primarily with the latest 

findings, the state of the art, i.e. the paradigm or dominant world-view of the day. In this 

context, history is considered non-essential because it deals with things that are out of 

date.   

 

By contrast, culture faces a much larger challenge, namely, to re-present changes in ways 

of knowing; changing meanings in different places at a given time (synchronically) and 

over time (diachronically). Culture is about both objects and the commentaries on them; 

about a cumulative body of knowledge; about collective memory and heritage. Here, 

history plays a central role and older does not mean less important or less relevant. 

Hence, a Leonardo painting that is 400 years old, or a Greek statue that is 2500 years old, 

typically have richer commentaries and are often more valuable than their contemporary 

equivalents. In this context, the science of meaning (semantics) is necessarily much more 

complex than semantic primitives. A semantic web in the cultural domain must enable us 

to trace how meaning and knowledge organisation have evolved historically in different 

cultures.  

 

This paper examines five issues to address this challenge: 1) different world-views (i.e. a 

shift from substance to function and from ontology to multiple ontologies); 2) develop- 

ments in definitions and meaning; 3) distinctions between words and concepts; 4) new 

classes of relations; and 5) dynamic models of knowledge organisation. These issues 

reveal that historical dimensions of cultural diversity in knowledge organisation are also 

central to classification of biological diversity.    

 

New ways are proposed of visualizing knowledge using a time/space horizon to 

distinguish between universals and particulars. It is suggested that new visualization 

methods make possible a history of questions as well as of answers, thus enabling 

dynamic access to cultural and historical dimensions of knowledge. Unlike earlier media, 

which were limited to recording factual dimensions of collective memory, digital media 

enable us to explore theories, ways of perceiving, ways of knowing; to enter into other 

mindsets and world-views and thus to attain novel insights aSome practical consequences are outlined.

Might I remind people that this thread started with a discussion

of how the pieces of the SemWeb are related to ontology.

 

John Cage's compositions are worth some discussion, but perhaps

the amount spent so far has strayed a bit off topic.
