IA Summit 08: Exploratory Search and Folksonomy
Exploratory Search and Folksonomy: Exploration Paths in Social Tagging Systems
Tingting Jiang
University of Pittsburgh
This was the more academic of the presentations yesterday. Not that entertaining, but an interesting analysis of the different types of classification, information seeking behavior, and 3 elements involved.
Hierarchical Classification / LCC, DC, Google Directory
- comprehensive, fixed, non-overlapping
- heirarchical, numerative
- universal, local
- high investment
- professional, formal
Faceted Categorization / Flamenco
- set of small heirarchies
- conceptual dimension
- less investment
- still professional
- navigational searching
- flexibility
- query
- fixed collection
Tagging Dyamic Clusters / Grokker, Clusty
- dynamic, post-retrieval, unique
- clustering algorhims
- automation, less complex & less costly
- ambiguity, instability
- vivisimo customization
Folksonomy / del.icio.us, Flickr
- flat, inclusive
- anyone, any language
- liberal, distributed, dynamic
- inexpensive, responsive
- vocabulary problem (different terms to describe the same things)
Information Seeking in tagging systems consist of 4 activities.
- Browsing
- Searching
- Being aware (tagging only)
- Monitoring (tagging only)
3 elements exist:
- Resources - information space
- Users - social structure
- Tags - information structure
Being Aware uses Resources & Tags)
- recent / popular searches
- recent / popular tags
Monitoring uses Users & Tags
- users of interest
- tags of interest
Searching uses Tags, Resources & Users
- tag
- username
- resource keyword
Browsing (dominates information seeking in social tagging)
- resource description
- user central place (where people store tags, etc.)
- tag navigation
Check out the presentation (coming soon) to see the graphical representation of how these concepts interact.
