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?

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”
![Page 5: Mdst3703 ontology-overrated-2012-10-16](https://reader035.vdocuments.site/reader035/viewer/2022062613/5456a2c7b1af9fc0638b4f6b/html5/thumbnails/5.jpg)
Each of these are made possible by the application of database logic

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.
![Page 7: Mdst3703 ontology-overrated-2012-10-16](https://reader035.vdocuments.site/reader035/viewer/2022062613/5456a2c7b1af9fc0638b4f6b/html5/thumbnails/7.jpg)
What are some differences between Shirky’s view of ontology and others we have read?
![Page 8: Mdst3703 ontology-overrated-2012-10-16](https://reader035.vdocuments.site/reader035/viewer/2022062613/5456a2c7b1af9fc0638b4f6b/html5/thumbnails/8.jpg)
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

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

What is the advantage of this kind of structure?

Trees can be easily navigated by people

Content can be classified in as many ways as there are perspectives
But this kind of organization follows from information stored in databases

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
![Page 20: Mdst3703 ontology-overrated-2012-10-16](https://reader035.vdocuments.site/reader035/viewer/2022062613/5456a2c7b1af9fc0638b4f6b/html5/thumbnails/20.jpg)
Examples
Delicious (web pages and tags) Flickr (images and tags) Twitter (tweets and hashtags, retweets)
![Page 21: Mdst3703 ontology-overrated-2012-10-16](https://reader035.vdocuments.site/reader035/viewer/2022062613/5456a2c7b1af9fc0638b4f6b/html5/thumbnails/21.jpg)
Effects
Cool visualizations Sometimes useful mashups The web itself becomes a large, socially
constructed database
![Page 22: Mdst3703 ontology-overrated-2012-10-16](https://reader035.vdocuments.site/reader035/viewer/2022062613/5456a2c7b1af9fc0638b4f6b/html5/thumbnails/22.jpg)

“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”
http://blog.ouseful.info/2010/09/09/additional-thoughts-on-tag-powered-context/
-- 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

With Web 2.0 and social media, the web itself becomes a big database
![Page 27: Mdst3703 ontology-overrated-2012-10-16](https://reader035.vdocuments.site/reader035/viewer/2022062613/5456a2c7b1af9fc0638b4f6b/html5/thumbnails/27.jpg)
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
Does this match the
situation in scholarship?
![Page 28: Mdst3703 ontology-overrated-2012-10-16](https://reader035.vdocuments.site/reader035/viewer/2022062613/5456a2c7b1af9fc0638b4f6b/html5/thumbnails/28.jpg)
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

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?
