I have a paper entitle "Designing Visual Languages for Description
Logics" for a special issue on visual languages for logic that will
appear in JOLLI (Journal of Logic, Language and Information), and
have just revised it in response to referees' comments. However, I
realized that none of the comments I have received were from a DL
perspective and would welcome some if anyone on this list has the
time and interest to read it.
The paper is available at
http://cpsc.ucalgary.ca/~gaines/reports/KBS/VLDL/VLDL.pdf and the
abstract is:-
Description logics originated from the formalization of semantic
networks as visual languages representing decidable subsets of first
order logic (FOL) useful in knowledge representation. Later research
on description logics has focused on issues of tractability of
subsets of FOL with differing representation capabilities, and on the
implementation of practical systems achieving the best possible
performance. Semantic network research needs to keep pace with these
developments in description logic and provide humanly attractive
representation capabilities for knowledge entry, editing, and
presenting the results of inference, that translate unambiguously to
the underlying description logics. This paper discusses the design
issues for such semantic network formalisms, and illustrates them
through detailed examples of significant knowledge structures
analyzed in the literature, including determinables, contrast sets,
genus/differentiae, taxonomies, faceted taxonomies, cluster concepts,
family resemblances, graded concepts, frames, definitions, rules,
rules with exceptions, essence and state assertions, opposites and
contraries, relevance, and so on. Such examples provide important
test material for any visual language formalism for logic, enabling
the role of visualization in understanding and communicating the
major issues relating to them to be assessed.
Any comments welcome. JOLLI has published little on DLs and it would
be good to be accurate and representative in what is said, especially
if there is related work that should be cited that I have missed, b.
