Background
• The MultimediaN E-Culture project
– Better understand how search is conducted in the Culture Heritage domain
• Rich, heterogeneous, combining highly structured and unstructured information, combining text and other media.
• Expert users vs. lay users
3
User Study Goal
To understand the cultural heritage experts’
information seeking needs.
– Why do cultural heritage expert search?
– What are the typical experts’ search task?
– What sources do they use?

User Study Participants
Total: 17 experts from 9 CH organizations
Role: researchers, curators, registrars, IT, teacher, student
Age : 21-60 years old
Sex : 11 Female, 6 Male
Affiliation: museum, freelance, university, CH institution
DL experience: basic (2), intermediate (12), expert (3)
5
User Study Setup
• Semi-structured interview, 2-3 hours
- Questions about daily activity
- Detail description of activity
• In natural environment
• Data: voice recording, photo, screenshots, and
answers to questionnaire
• Qualitatively analyzed
6
Why do CH experts search?
• Object handling: restoration, acquisition, or loan
• Exhibition: finding themes, comparison studies
• Publication: for peers or for general public
• Managing collections’ documentation: updating records
• Building thesauri: used for annotation and search
7
Key Findings
1. Information gathering as primary task
2. Searching in multiple sources
3. Communication with other experts
4. Provenance and trust
8
Typical information seeking tasks
(Kellar, CHI 2007)
• Fact finding (FF)
• Information gathering (IG)
• Keeping up-to-date (KUTD)
• Information exchange (IE)
• Information maintenance (IM)

Distribution of information seeking tasks
Information gathering
– Comparison
– Relationship
– Topic search
– Exploration
– Combination

Comparison Search
“What objects from the Middle-East do other
museums in the Netherlands have? Is there any
tribe or region not represented in our collection or in
the collection of other museums? If there is, we
need to find out exactly what kind of object we
should get.” [P14]
11
Exploratory Search
“On specific situations, such as in the Staircase
project, I look a lot at similar examples of artworks
in staircases, for instance, art projects connected to
landscaping or city planning, something like that.”

3. Provenance and Trust
“For the thesaurus we decided to use all the
literature which we agreed upon. Several years ago
we did not accept anything from Internet, but
nowadays some. The curators are a little bit afraid
of it, who says the information is correct?” [P2]
26
4. Communication with other experts
• “We have regular meetings with other museums to
decide which words should be in the thesaurus.”
[P2]
• “… I talk to many people who are experts in
Rembrandt.” [P6]

Summary and Future Work
• Information gathering as primary task– Follow up study to understand information gathering search
process better in cooperation with Rijksmuseum & KIT
– develop tool which is geared more to IG rather than FF
• Searching in multiple sources– integration of search functionality across sources
• Provenance and trust– communicating trust and provenance in the interface.
• Communications with other experts– support finding expertise
– support collaborative search
