A technique for representing human krowledge and judgments developed by O s s o r i o I is d e s c r i b e d . A m a t r i x of j u d g m e n t s obtained Irom human experts is factor analyzed, and the r e s u l t i n g ~actors are used to u e f i n e a n n - d i m e n s i o n a l space, items may be assigned positions in the space by a weighted sum of their component factors. items close to one another geometrically should be close conceptually. Is a signilicant amount of inlormation l o s t in t h e factor analysis? H o w s t a b l e is the t e c n n i q u e ~ D o e s the f a c t o r a n a l y s i s extract "conceptually significant" factors? The technique is "humanistic" in approach, anu there are ~ays to d e t e r m i n e how well objects are represented in the s p a c e . Systems using this method have been promising in information retrieval and medical diagnosis. I Peter Ossor. io, "Classification Multivariate behaviorial ~esearch 479-524.
