User Issues in a Bottom-up + Top-down
Tagging Application

3. my name is Andrea Resmini
I'm an Information Architect
I design information spaces
coordinate REG-iA, the Research &
Education Group in IA
founded the Journal of Information
Architecture
one of the designers of the
FaceTag engine project
6. tags are flat free-form keywords liberally
assigned by users
collaborative tagging is widely used to
organize, browse and share large online
collections
folksonomies are tag-based, bottom-up,
user-generated emergent classification
systems
16. user experience disadvantages
user interfaces (tag clouds) with self-
sustaining predominance cycles
visual clutter
no map-making
editing interfaces
18. “Information seekers in large domains
need to deal with meaningful groupings of
related items in order to understand
relationships, build a mental map, and
decide how to proceed”
19. So, how do we move
from tags to meaningful groupings
and how do we navigate them?
20. a number of tools and techniques
have been proposed
29. faceTag introduces a multidimensional,
semantically richer paradigm based on
the CRG faceted theory which provides
tag hierarchies
system facets to which tag hierarchies
are assigned
seamless browsing and searching
30.
31.
32. faceTag then allows to
add structure and context to flat tags
navigate along several dimensions
simultaneously
refine and broaden filtering criteria on
the fly, with no dead ends (engaging and
zooming)
36. exploration, discovery and iterative
query refinement are supported
37. As facets are particularly suitable to
classify homogeneous collections, the
combination of facets + tags amplifies
both the information scent and berry-
picking capabilities of the system
38. this happens along the two axes of IA
the vertical paradigmatic axis, where
similar tags on the same facet are
recalled
and the horizontal syntagmatic axis,
where all other tags pertaining to the
same facet are recalled and suggested
47. uses metaphors from other tagging
applications (del.icio.us, Rawsugar)
introduces a visual top-to-bottom
hierarchy among facets
has a 'duct tape and some glue'
feeling to it
goes against some common UI
principles
