Bias

Let’s make it explicit !

ISKO 11, Rome, February 2010:

“Paradigms and conceptual systems in KO”

Page 5: Knowledge organization

Bias

• influence of classification on search and on everyday life [Bowker & Star 1999; Ridi in press]

• prejudices in LCSH [Olson 2002; Kublik et al. 2004]

• development in thesauri [Severino 2005]

• main classes in LC, Soviet, Chinese classifications...

Bias

[Angelini 2005]

Eastern vs. Western KO

• calligraphy as a major art in Korean DC 700 [Kwasnik & Rubin 2004]

• philosophy in BC2: different facets [Biagetti 2009]

• philosophy ? religion

“Buddhist “Buddhist ethics” worship”

Folk taxonomies

New Guinea native Western zoologist

Page 10: Knowledge organization

Folk taxonomies

• 93% same bird species identification 7% strictly-related species [Diamond 1966]

• almost all same species of birds but no distinction between ants [Mayr in Wilson 1992]

• plant species in Chiapas: 82 underdifferentiated 68 exactly corresponding (including 40 introduced) 50 overdifferentiated

[Berlin et al. 1966]

All dimensions are needed

• Ontological (real world)

• Epistemological (our knowledge)

• Sociological (milieu, purpose)

viewpoint warrant [Beghtol 1998; 2002]

Representing viewpoints

As many KOSs as viewpoints(domain analysis)

but

the global information society needs interoperability...

Special ILC deictics

mqU the typical animals

mqX some animals

mqXA the actual animals (i.e. there are animals)

mqXX what animals?

mqY the individual animal (e.g. Laika)

mqZ the mentioned animal (anaphoric or cataphoric)

Test applications

• bibliography on traditional culture in Northern Apennines

• bibliography on bioacoustics

• bibliography on facet analysis

• Web directory on chemistry

Page 22: Knowledge organization

Development

• basic idea for viewpoint representation

• more complex, real cases to be considered

• parallel development of standard schedule and local schedules

• can any local concept be translated into facet combinations?

No KOS is perfect......but useful KOSs are feasible
