[OpenCyc-devel] Query for all instances of a predicate

[Paul F. <pf...@cs...>]

Dear Sir,

I am a OpenCyc newbie and I have some questions that I could not figure out
yet. If anyone has time and can respond to my questions, please let me know.

Question 1: I access OpenCyc from Java and I wonder how can I query for all
instances of a predicate or class. I want to collect a list of all results.
For instance, I want to collect all spatial things:   (#$isa ?X
#$SpatialThing)

or, I want to collect all pairs of people liking other people:
(#$likesAsFriend ?X ?Y)

For example,

(NEW-CYC-QUERY
  (LIST #$isa #$BillClinton #$SpatialThing) #$PeopleDataMt
  (LIST :MAX-NUMBER 1))

works, but

(NEW-CYC-QUERY
  (LIST #$isa ?X #$SpatialThing) #$PeopleDataMt
  (LIST :MAX-NUMBER 1))

tells me that ?X is unbound.

Question 2: How do I collect this list in Java?

Thank you,
Paul.
