Get Protege3.5, jess-tab jess.jar(for now),Start it then: project-> configure to select jesstab batch load https://github.com/MBcode/CLIPSmsc/blob/master/jutl.clp for a few lisp like utils
One of the MachineLearning pprj I use in (cl-)kme uses protege, and I could store/display/edit other(km)constructs w/it, incl maybe some other basic (lisp)code;
Algernon(tab)uses a lisp and is very KM like; I've heard from the lsw2 people abcl can be used. alg-tab also has a server. Really just playing right now.
Can load arff and have mlcl (machine-learning+(protege)KnowledgeAcquisition) Can load owl file/s like those in the LUBM benchmarks, which I mention in: http://bit.ly/TP8gfz Trial loading of a ttl file for data-cube data: https://code.google.com/p/publishing-statistical-data/source/browse/trunk/specs/src/main/vocab/cube.ttl?r=180 So, moving toward better self described (numeric)data-sets, that can be used by a variety of learners
http://lispinsummerprojects.org/ started in kme then cl-kme then some of that ended up here /too
Made http://cliki.net/machine%20learning and plan further work, here and elsewhere.
