Semantic Tagging in MaphubStanford University, April 2013

19.
Goals • Study the effects of semantic tagging on • tag production (# tags) • types and categories of types added • user task loadStanford 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-TLXStanford 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
