3. Web 2.0

The participatory web: its elements include a number of tools that encourage user contribution and that have transformed online publishing from a one-way model to a multi-directional one.

5. Why social tagging? 6. 7. 8. From: J. P. xxxxxx@xxxxxx.com Date: Sat, 26 Aug 2006 11:24:43 -0700 To: timeline@metmuseum.org Subject: Looking for a painting Please help: I have been looking on and off for yearsfor this painting. The painting is of a very well dressed renaissance man standing in a room (a library) in front of him on a table is a large hour glass. The painting has very rich colors.I have talked to a lot of people and they have said they have seen this painting but can't remember its name or the name of the artist. Could you please use your resources to find this painting? 9. 10. What J. P. knows: painting Renaissance standing man very well dressed library hourglass table rich colors What a Met curator knows: Portrait of a Man , ca. 152025 Moretto da Brescia (Alessandro Bonvicino) (Italian, Brescian, born about 1498, died 1554) Oil on canvas; 34 1/4 x 32 in.

Building a suite of tagging tools

26. The steve tagger: an open-source configurable tagging tool 27. 28. 29. The steve term review tool: to review, annotate, and manage tags 30. The reporting suite: supports the review and analysis of research data 31. steves2006-08 Research Results 32. Tags are different than museum documentation

• 86%of all tags not found in label copy

• 62%of distinct tags not in AAT

• 85%of distinct tags not in ULAN

33. Museum professionals found most tags useful

• 88%of tags were useful

• If you found this work using this termwould you be surprised?

34. Tags could improve searchingTags Submitted: 20th century, baked goods, balanced, balancing, cake , cake stand, cakes , cherry on top, coconut cake, cream filling, dessert, desserts, food, frosting, genoise, lemon merangue, Lollypop shadows, painting , pie, plates, portrait, shadow, shadows, simple, tall stands, Thiebaud , three, trio, white background WayneThiebaud(1920-1963) Display Cakes , 1963 Collection SFMOMA In this example, only four user-contributed terms appear in the online search database 35. Tags are almost always useful when they are assigned two or more times. 36. Institutional Affiliation Matters

• Users invited to tag by The Metropolitan Museum of Art were4times as productive

• Multi-Institution Tagger:22 tags / user

• Single Institution Tagger:82 tags / user

Concerns and opportunities

40.

Incorrect information contributed

Malicious or profane terms contributed

Potential to diminish the value of authoritative content provided by the museum

Overly personal information mixed with otherwise useful content

Lack of standardized terminology may impede cross-collection searching/browsing/data management

Objects/artists exposed to inflammatory speech or criticism

Managing new source of data presents logistical concerns

Possible cons (from the class discussion) 41. What are taggers telling us? 42. The works may evoke strong emotions Jackson Pollock, Autumn Rhythm Tag: piece of sh*t 43. They interpret differently Winslow Homer, The Gulf Stream Tags: sharks, dolphins, rocky shore 44. They make private associations John Singleton Copley,Portrait of Paul Revere Tag: Jack Black 45. They make private associations 46. They have complex ideas to express 20% of all tags contributed were multi-word terms. Raghubir Singh Bazaar Through Glass Door, Bombay Tags: modern India, old meets new, red shopping bag, defining moment 47. They are not malicious Only 14 of all tags matched the steve blacklist of profane terms. 48.

What do you do with a million tags?

The steve team imagines using a variety of post-collection processing tools--including both human and machine assessment--to assign values or weights to tags based on their term type (facet), contributor (expert/nonexpert), or frequency

What are the implications for data management if term processing is necessary to make a large body of tags useful?

Cons (some others): term management requirements 50. Cons (some others): Ambiguity 51.

The Grand Prix was run in 1912 on the circuit of Dieppe, and while No. 6, a Delage, was a favorite,

it was actually the Peugeot, with the ace driver Georges Boillot at the wheel, that won, at speeds

reaching over one hundred miles an hour

Exciting possibilities: real expert tagging 52.
