5 rules for museum content
• 1. Discoverable – it is where I am and where I look for it.
• 2. Meaningful – I can understand it.
• 3. Responsive – to my interests, moods, location.
• 4. Useable/Shareable – I can pass it on and share.
• 5. Available in all three locations – online, onsite and
offsite.

• Inspired by the work of Luis von Ahn (among
others)
• The goal of the game is consensus between
players (which also works as filter)
• Fun and competition as motivation
• Almost 600 hours of material / 2.400+ items

Why?
1. Bridging the semantic gap
2. Add more (+ fine grained) knowledge
• Time-related metadata (inter-video search)
3. Role in workprocesses of the future
4. Interaction between the archive /broadcaster
and the public
• 160k people are volunteering in CH in the
Netherlands (win-win)

20.
• Basic rule – players
score points when their
tag exactly matches the
tag entered by another
player within 10 seconds
• Multiple other scoring
mechanisms to create
various tag incentives

21.
Traffic
• Generating a constant flow of traffic is a challenge!
Strong partners and links to Waisda? on external
websites proved important.
• Example: in October 2009: great boost through
Farmer wants a Wife website
In
one
week:
•
Number
of
tags
tripled
to
160.000
•
Number
of
registered
players
doubled
to
362

22.
Results (evaluation May-November 2009)
• Since the launch in May 2009:
• 44,362 pageviews
• 12,279 visits (3+ min online)
• 555 registered players (but thousands of
anonymous players!)
• 340,551 tags added to 602 items
• 42,068 unique tags

Tag evaluation by documentalists
• Farmer wants a Wife, Westerman’s New World
• Tags describe mainly short segments, and are often not very
specific. Tags do often not describe programmes as a whole.
• BUT! Can be solved by applying ontology alignment.
• The WNW tags were most useful and specific: content of a
programme influences tags specificity.
