Disorder – dispersion.

TAGS

Pupils have learnt how to tag during the previous experience (on-paper);

They get confident very soon with the application;

Tag visualization + Tag Cloud are automatically created by the application.

NOISE: ‘colorata’ ‘colorati’ ‘colorato’

SYNOMYMS: ‘quadro’ ‘dipinto’

UPPER / LOWER

CASE

SINGULAR/ PLURAL: ‘persona’ ‘persone’

Agreement on some “rules”:

To employ only lower case;

Not to inflect adjectives;

To employ plural nouns (as if we were thinking of a group of several elements)

“Tiding up Tags”:

Not easy (singular/plural)

Membership > CLASSIFICATION Description > CATEGORIZATION

Third Italian IA Summit - Forlì February 2009 - Renata Durighello 28

Plural nouns refer to the idea that the resource is member of a group / class

Tags are associated to the resource as far as they describe it.

Can I classify?

Classification begins when I’m able to talk about the resource, to say something about it.

Broad Folksonomy VS Narrow Folksonomy:

BF allows to point out the most “important” Tag(s);

Collaborative Tagging

to share rules , euristics,…;

Tag noise

mis-spells, synonims …;

Tag unreliability

harvesting information;

Interference :

Tags meaning membership;

Tags meaning description;

Third Italian IA Summit - Forlì February 2009 - Renata Durighello 31

Whose fault is it?

Trying to arrange the Tags we produced into a taxonomy (card sorting, trees, maps…).

Going on tagging other kind of resources(documents, textual resources).
