AaronSw: Thanks Dave!
AaronSw: Dave would probably warn that the URL is subject to change.
AaronSw: Dave should really fix the mime type on this...
 
SeanP: Blogged picture of Art Barstow
 
SeanP: SEM-Dev, Discussion of SEmantic Memory
AaronSw: beware, there's restricted membership ;-)
edd: Is there any reason the archives aren't public here?
edd: If you ask me, that's a big shame.
 
danbri: See further reading section for link to Sean's transcription of the ENQUIRE manual.
 
danbri: ...so we know which bit of the picture depicts which person. I wonder about using foaf:depicts, or a more specialist property.
SeanP: Is actually at http://blogspace.com/pictures/photo-view?photo_id=3721
SeanP: Try: Aaron's photo deeley
edd: Would some kind of XPointer scheme do the trick? Unsure if you have to drag imagemaps or SVG into it, it seems like it stops it being an atomic resource then.
 
danbri: The spreadsheet work is interesting, might help reflect spreadsheet data out into RDF/XML/DAML world... Jocelyn's Prolog demos are also nearby.
 
danbri: Of interest to anyone following the RDF IG threads on Guha/McCarthy contexts. See Guha's home page for a link to his thesis for related discussion of contexts.
danbri: The Microtheories paper describes Cyc's approach to this circa 1992, including lifting rules for connecting different theories at different representational granularity together into a single composite KB. "In Cyc, a context (or microtheory) is a way of talking about a group of related assertions by representing this grouping explicitly with a Cyc unit."
 
danbri: This piece provided a compare and contrast between Cyc's ontology, Princeton's WordNet effort, and EDR (Japanese work I'm unfamiliar with). I've used WordNet to produce a 50,000 class RDF schema for use in SW apps; since the Cyc ontology is now being opened up, might be worth revisiting this comparison. The Wordnet Book is also well worth reading.
 
danbri: They're going to use DAML, DARPA's RDF-based agent language, for the public exports of the data.
danbri: Cycorp's press release claims W3C are considering DAML "as a standard". That's not true, though the DAML work will inform the work of current and future Semantic Web Working Groups.
danbri: In particular, I expect the DAML formal semantics and recent investigation of an RDF view of XML datatypes will prove very useful for the RDFCore WG. And I hope to see a future 'Web Ontology' group build on the rest of the DAML research.
danbri: Some time ago I had a quick attempt at turning the upper levels of the Cyc ontology into RDF. It mostly worked, except I couldn't reliably tell literal data from references, which made the RDF translation lossy.
danbri: Jorn Barger's RobotWisdom site contains a number of Cyc-related links including a critique from 1994 based on interaction with the system and discussions with Guha and Lenat. It's unclear how things have progressed since 1994. Personally, I'm massively skeptical about this as an approach to AI, but curious about the possibi
danbri: ...possibilities for using the Cyc ontology online. Similar potential to WordNet in that respect (@@todo: dig out citation for ACM comparision of WordNet and Cyc ontologies).
