3. Review
Manovich’s thesis: the database is a symbolic
form
– Produces a figure/ground reversal between
paradigmatic resources and syntagmatic products
– Between process of production and finished
product
How is this reversal represented in Vertov’s
film?
– How does Vertov “solve” the problem of relating
paradigm to syntagm?
4. Overview
Today we look at the development of the
database as symbolic form on the web
– Symbolic forms shape cognition
In particular, we look at changes in new media
associated with Web 2.0
– Web 2.0 is, roughly, the web after Google
In many ways, the Web 2.0 revolution is the
result of the “databasing of the web”
5. Each of these are made possible by the application of database logic
6. Clay Shirky is one of
the most important
theorists of the post-
Google web
American media theorist. Studied fine arts at Yale.
Teacher, writer, consultant. Books include Here
Comes Everybody and Cognitive Surplus.
7. What are some differences between Shirky’s
view of ontology and others we have read?
8. All of the theorists interested in models have
assumed that there is a model in the text
that can be retrieved by scholars (experts)
Shirky embraces the network effects of Web
2.0, in which user participation outstrips the
capacity for experts to control content
The text emerges as a site of competing
interpretations
10. This is the biggest rationalization effect so
far:
That our view of knowledge itself is an effect
of how we organize the documents that
store it
As Wesch says, we will have to rethink some
of our deepest notions
11. For example …

nature and logic

Art), 1305
12. What is the advantage of this kind of structure?
15. What is the advantage of this kind of structure?
16. Content can be classified in as many
ways as there are perspectives
But this kind of organization follows
from information stored in databases

19. The Method: Tags and URLs
Links have addresses
– <a href=“http://somewhere.net”>Click me</a>
– Addresses are URLs
Tags can be used to classify these addresses
– Delicious
– Diigo
Anything can have an address and be tagged
– Images in Flickr
– Things in the world
20. Examples
Delicious (web pages and tags)
Flickr (images and tags)
Twitter (tweets and hashtags, retweets)
23. “we could mine the tweets surrounding an
archived hashtag in order to generate a topic
based context that would persist after the
event had been long gone”
Tag Powered Contex
-- Scrape tweeting links using the hashtag from the
twapperkeeper archive and feed them to a facet of the
search engine
-- Look to other services, such as delicious, to see who has
been bookmarking URLs with the particular tag
-- Look to delicious to see who bookmarked the ALTC2010
homepage

26. With Web 2.0 and social media, the
web itself becomes a big database
27. When ontology doesn’t work
Domain
– Large corpus
– No formal categories
– Unstable entities
– Unrestricted entities
– No clear edges
Participants
– Uncoordinated users
– Amateur users
– Naive catalogers
– No Authority
28. Question
Are Unsworth’s and Shirky’s positions
compatible?
– What are their major differences?
– Both approaches want to generate data and
produce visualizations …
– Both approaches expose classifications that are
surprising and interesting

31. Wesch
Why is it important to separate form and
content?
How do XML and RSS relate to Shirky’s and
Unsworth’s positions?
How is Wesch’s argument similar to Shirky’s?
Unsworths?
How is it different from both Unsworth and
Shirky?

Editor's Notes
This kind of structure is optimized for human retrieval
Libraries are like databases – they have structures too
But this kind of structure
Example
Eric Fischer creates maps that merge geographic locations with geotagged photos from Flickr and tweets from Twitter. Red dots pinpoint the locations of Flickr pictures, blue dots show tweets, white dots mark places that have been posted to both. This map of Washington, D.C., shows messages concentrating around the national landmarks and power corridors of the city’s federal zone.http://anthonyflo.tumblr.com/post/7590868323/photographer-and-self-described-geek-of-maps
