Do user tags differ from museum documentation?
27. Research Questions: Extended Museum Documentation
Are Other Forms of Museum Documentation More
Useful?
Genres
✓ gallery label text
✓ docent tour talking points / tour scripts
✓ special exhibition catalogue entries
✓ permanent collection guidebook text
✓ curatorial analysis or notes
✓ scholarly article
✓ web site 'feature' texts
✓ audio tours or podcasts
✓ newspaper/popular article
28. Research Questions: Extended Museum Documentation
I. Text mining museum extended
documentation for the sorts of terms we get in
tagging cannot be algorithmic
II. Extended documentation is not better than
online museum documentation
III. Public genres of documentation are not
meaningfully better than scholarly and
internal for tag matches.
IV. False results from Inapplicable matches if
extended documentation was searched for
