Resumo(s)
Metadata is indispensable for data discoverability and interoperability. Most
datasets utilize automatic techniques to create metadata; nevertheless, metadata
creation still requires manual interventions and editions, yet manually metadata
creation is a tedious task. The study proposes a prototype that introduces
speech recognition in the metadata creation process. Users can generate content
by speaking. Afterward, the prototype transforms it into metadata with
JSON-LD format, a popular metadata format and utilized by mainstream
search engines. A user study was conducted to understand the impact of
speech-based interaction on user performance and user satisfaction. The result
showed no signi cant performance di erence between speech-based and typebased
by the e ciency, slip rate, and di culty rating evaluation. In the user
experience evaluation, participants consider the type-based metadata creation
is pragmatic, and speech-based metadata creation is hedonic. It suggests
that the mix-mode can complement mutually with the advantages of each
and optimize the user experience.
