  • 14. Benefits of TaggingBenefits of TaggingTags... ...are simple ...rely on an open vocabulary ...can be aggregated ...allow users to differ on the definition Arkaitz Zubiaga (UNED) Wikipedia & Social Tags August 28th, 2009 14 / 33
  • 15. Benefits of TaggingHow Can We Navigate Through Tags?Three ways to navigate through tags1 : Pivot-browsing Popularity Filtering 1 Tagging: People-Powered Metadata for the Social Web, by Gene Smith Arkaitz Zubiaga (UNED) Wikipedia & Social Tags August 28th, 2009 15 / 33
  • 16. Benefits of TaggingTag Navigation: Pivot-browsing Benefit: Switching to related tags/topics. Arkaitz Zubiaga (UNED) Wikipedia & Social Tags August 28th, 2009 16 / 33
  • 17. Benefits of TaggingTag Navigation: Popularity Benefit: What has people considered interesting/relevant for a tag? Arkaitz Zubiaga (UNED) Wikipedia & Social Tags August 28th, 2009 17 / 33
  • 18. Benefits of TaggingTag Navigation: Filtering Benefit: Retrieving documents containing a tag(s), but not another. Hence, users can retrieve articles related to a topic, and excluding a subtopic. Arkaitz Zubiaga (UNED) Wikipedia & Social Tags August 28th, 2009 18 / 33
  • 19. Benefits of TaggingHow Can Tagging Enhance Taxonomies? (1) Definition Categories must be created before using them, unlike tags, which are created the first time a user uses them Each user defines a set of tags, generating a global weighted set of tags as a result. This allows a tag to be more relevant than another, unlike with categories, for which an agreement among users is necessary. Tags can handle synonimy, hypernims, hyponims,... unlike categories. Arkaitz Zubiaga (UNED) Wikipedia & Social Tags August 28th, 2009 19 / 33
  • 20. Benefits of TaggingHow Can Tagging Enhance Taxonomies? (and 2) Navigation and search Providing the aforementioned new ways to navigate. Providing new terms to describe the articles.

  • 32. ConclusionsConclusions A social tagging system would provide new ways to navigate Wikipedia: Pivot-browsing Popularity Filtering Bottom-up classification besides top-down classification. An experiment with tags over Wikipedia shows encouraging results. Providing new unexisting terms. Providing new ways to navigate through tags. Helping to improve the search engine. Discovering popular articles. Arkaitz Zubiaga (UNED) Wikipedia & Social Tags August 28th, 2009 32 / 33
