  1. The meaning of facets in nondisciplinary classifications Claudio Gnoli (University of Pavia) (ISKO Italy) pictures by Caterina Barazia

  2. in memory of Douglas Foskett, whose writings are far greater than the sum of their words...

  3. Disciplines are an arbitrary constraint on classification schemes Brown (1906) Kyle (1959) Foskett (1961, 1970) Austin (1969) Beghtol (1998) Williamson (1998) Szostak (2004) López-Huertas (pers. comm.)

  4. Defining classes as disciplines and their subdivisions is a top-down approach

  5. An alternative bottom-up approach Farradane (1961) Austin (1969) Foskett (1970) Gnoli & Poli (2004)

  6. Facet analysis has usually been applied to disciplinary schemes Objects Parts Properties Materials Actionsin Medicine:in Technology: Operations = Therapies = Working ... Agents Space Time

  7. What is the meaning of facets when they refer to phenomenon classes? class: Cars Price? Colour? Fuel? Firm? Bodywork?

  8. Predicate logic “I go from Pavia to Vienna by train” moving me Vienna Pavia train moving object destination provenance mean P A1 A2 A3 A4

  9. Any class can be considered as a predicate, with a set of potential arguments = facets with organ [A1] at growth stage [A2] affected by disease [A3] living in habitat [A4] plants [P]

  10. Integrative Level Classificationresearch project w w w . i s k o i . o r g / i l c

  11. Free classification (Brisch in Kyle 1956) (Gardin 1965) “Italian vineyards” cultivation : grapes : Italy S Mpfdg K^ei

  12. Ambiguities with specialized documents “The dialect of the village of Portalbera, and wine terminology in Oltrepò pavese” villages : cultivation : words : grapes : Oltrepò pavese Tle S Ruo Mpfdg K@f ...Facets are needed !

  13. Definition of facets Relations typical of a phenomenon with other phenomena Plants typically:Cars typically: have organs, have some bodywork, are in some growth stage, use some fuel, are affected by some disease, are made by some firm, live in some habitat, ... ...

  14. Freely faceted classification “Italian vineyards” S cultivation 4mpfdg of plant: grapes 2k^ei in region: Italy S4mpfdg2k^ei ...Notation gets complex and long: suitable for machine processing, but not for shelving (Austin 1976, 1979)

  15. Extra-defined foci “Italian vineyards” S cultivation 4 [Mp] of plant... 4fdg of grapes <= Mpfdg “grapes” 2 [K^] in region... 2ei in Italy <= K^ei “Italy” S4fdg2ei

  16. General extra-defined foci Mp “plants” T “artifacts” Ne perception Ne8 [*] of object... Ne8mp “perception of plants” Ne8t “perception of artifacts”

  17. Context-defined foci Xi music Xi3 [:] played by instrument... Xi3k “music played by stringed instruments” Xi3n “music played by wind instruments” place of unique definition (Farradane)

  18. Cascading facets X arts X3 produced by technique... Xi music Xi3 music played with instrument... Xiv compositions Xiv3??

  19. Ongoing work • check and tune solutions suggested by the general model • write more PHP code to manage facets and foci • build a Web assistant for easy construction of classmarks • ...

  20. ...Nondisciplinary (faceted) classification is feasible
