Geoff

Geoff: People, I'm writing a grant still. However, if you read the PxTP paper, and have spare time, I'll apreciate comments on the slides ... http://www.cs.miami.edt3u/~tptp/Seminars/CombiningProofs/ <---Where are the slides? <-- Click the title, it is 8 html pages. TODO: Geoff needs feedback by next Thursday Joke at http://www.cs.miami.edu/~tptp/Seminars/CombiningProofs/Contents.html

Indirection of pmlp:INformation

Is this an example of Cynthia's "Cynthia: a value is a "A query request", the value of the property is "indirect" and needs further processing to get the value." example "37": ("just-in-time" property value example:)

Cynthia says the above is "indirection"

Tim: What is the indirection?

Cynthia: indirect b/c I need to "execute" it.

Cynthia: it is NOT a pointer to a document. You have to "do a command" to get the result, then the result is what you use.

Cynthia: direct URI will point to one section of a document, that is what you markup. you have to execute to get to it.

Cynthia: normally, you have a URI and parse the URI with a jena reader. Jena reader with parse the URI to fetch the document. EXAMPLE of "direct" URI that Cynthia prefers: (not "prefered", but "different") http://inference-web.org/registry/IE/PROTEIN.owl#PROTEIN

Tim: what is liked:

  • it is a document
  • it is a URI
  • it points to an existing document; it is "there"
  • it is static
  • the RDF is already there
  • if not PML, still OK. You just get a blob of text.
  • has to be Information before it can even get hasPRettyString and/or hasRawString. - (e.g. first.ttl.rdf - 3 NodeSets; first 2 have conclusions that do not appear as Information; they don't have hasPrettyString nor hasRawString (the third does))
  • returned desctitions hasPRettyString and/or hasRawString

NOTE: hasPrettyString is preferred over hasRawString. Cynthia: more of "37"ish (?query=PREFIX") will happen Conclusion is instance of Information, hasPrettyString or hasRawString displayed in browser. if conclusion is NOT Information, will not display anything. done: Tim to look at the NodeSet that actually has a hasRawString. This has a hasRawString with an HTTP header in it: http://inference-web.googlegroups.com/attach/e3bfc3e5ac1bba0e/first.ttl.rdf?gda=R_cJS0cAAADoGr4Ggo5yYfrgMrpQVIhoFKX4L7UHF5MSHz5KpQLwnfrdiFWRRKMGkHJlnuG5gyMbQwFxJw55cVwemAxM-EWmeV4duv6pDMGhhhZdjQlNAw&part=2 the 3rd nodeset has conclusion string of :
