Disciplines are an arbitrary constraint on classification

Defining classes as disciplines and their
subdivisions is a top-down approach
An alternative bottom-up approach

Foskett (1970)Gnoli & Poli (2004)
Facet analysis has usually been applied to
disciplinary schemes

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

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, ... ...

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

...Nondisciplinary (faceted) classification
is feasible
