Stanford University, April 2013
Goals


                     • Study the effects of semantic tagging on
                      • tag production (# tags)
                      • types and categories of types added
                      • user task load

Stanford University, April 2013
Methodology
                     •       in-lab, within-subject design with 4 tag creation
                             methods as varying condition

                           •      Label-based tagging (LT)

                           •      Suggestive tagging (ST)

                           •      Semantic tagging (SMT)

                           •      Semantic tagging with context display (SMT-CTX)

                     •       24 student participants

                     •       pre- and post-test surveys incl. NASA-TLX

Stanford University, April 2013
Results Summary

                • Semantic tagging (as implemented in
                        Maphub) does NOT affect
                           • tag production
                           • types and categories of tags
                           • user task load
                ...but provides tagging relationships to well-
                defined concept definitions.

  • 17. Semantic Tagging Model u t rx ry about K r t u Semantic tagging Label-based tagging t1 [Marlow et al. 2006] + rx ry u rz - t2 K Semantic tagging with user feedback [Haslhofer et al. 2013] Stanford University, April 2013
  • 18. Semantic Tagging in Maphub Stanford University, April 2013
  • 19. Goals • Study the effects of semantic tagging on • tag production (# tags) • types and categories of types added • user task load Stanford University, April 2013
  • 20. Methodology • in-lab, within-subject design with 4 tag creation methods as varying condition • Label-based tagging (LT) • Suggestive tagging (ST) • Semantic tagging (SMT) • Semantic tagging with context display (SMT-CTX) • 24 student participants • pre- and post-test surveys incl. NASA-TLX Stanford University, April 2013
  • 21. Results Summary • Semantic tagging (as implemented in Maphub) does NOT affect • tag production • types and categories of tags • user task load ...but provides tagging relationships to well- defined concept definitions. Stanford University, April 2013
