Folksonomies Folksonomies Document Transcript

  • What if the users decided where the books should go? Folksonomies and the de-professionalization of metadata creation Edward Bilodeau Centre for Continuing Education McGill University Objectives • Introduction to folksonomies • Overview of common tools • Relationship of folksonomies to taxonomies and LIS 1
  • Background • New tools are launched (~2004) Flickr (photos) Del.icio.us (bookmarks) • These tools allow users to add their own descriptors (i.e. tags) to items they have posted • These tags are shared (public) Flickr http://www.flickr.com/ 2

  • Emergent Behavior • People were creating their own ad-hoc classification systems using their own words • People were using these classification systems To retrieve their own items (i.e. photos, bookmarks) To retrieve items posted by others To discover new items To find people with similar interests What do we call it? • August 2004: Discussion on IIA mailing list regarding “social classification” • Thomas Vander Wal: folksonomy ~ Metadata that is created by users, primarily through “tagging” • Seen as an alternative to top-down taxonomies taxonomies are difficult and expensive to create, maintain, and use folksonomies are easy, inexpensive and meaningful to users 13

  • folksonomy librarian !?!?!?! concepts, ideas, words creator tag-space resource users concepts, ideas, words Del.icio.us Demo • Jon Udell, Infoworld The ability for users to share tags is critical Provides users with feedback, opportunity to adjust their tagging to current use • Demo: http://weblog.infoworld.com/udell/gems/delicious.html Local vs Global tags (“buckets”) Locating other users Tag cleanup Tag normalization 16
  • Problems • Ambiguity Lack of shared understanding and/or lack of shared vocabulary for describing shared understanding Single tag insufficient for describing item • Synonyms • Handling multi-word tags web development, webdevelopment, web-development webdev, wdev, wd • Tag spam • Coverage is based on use (good or bad?) (Tentative) Prediction • Folksonomies are based on social network consisting of “all people using the tool” Currently early adopters Relatively small numbers Potential of shared understanding and meaning Enable system to provide value (retrieval and discovery) As numbers of user increase, Discovery value may continue to increase Retrieval value will decrease, as necessary shared understanding dissolves Tools will need a way to provide users to define social groups smaller then “all users” 17
  • Relevance to LIS • Interesting to study how users categorize resources • Potential to become another way people access information • Provides some benefits at much less cost (compared to formal process) • Seen as a compliment to formal taxonomy/classification • Still very cutting edge Tools are limited/immature (from a folksonomy POV!) Early adopters (i.e. tech deviants) Resources • Del.icio.us http://del.icio.us/tag/folksonomy • Wikipedia http://en.wikipedia.org/wiki/Folksonomy • Adam Mathes (2004) Folksonomies - Cooperative Classification and Communication Through Shared Metadata http://www.adammathes.com/academic/computer-mediated- communication/folksonomies.html • Slides from the IA Summit folksonomy panel http://atomiq.org/archives/2005/03/ia_summit_folksonomies_panel.html • Tools Delicious: http://www.flickr.com/ Flickr: http://del.icio.us/ 18
  • Homework • Do your readings • Create accounts and try out the tools • Think about how you could use this technology within the context of a library or information service to improve access to your collection Thank you. 19
