Enhancing C-Span Video Archive with Practice Capital Metadata and data journalism APIs
The presentation argues that the C-Span archive is not a mere repository of moving pictures. It can also be seen as a one of a kind “big data” repository. If processed from a “practice capital” perspective with quantitative and network analytic tools, such data can significantly extend the capabilities of C-Span archives by identifying the central actors in a debate and their ability to sway it. The proposed approach may serve the public interest though API tools that support third party development of visualization and analytic apps, which can lead to more informed debates and new forms of data driven journalism.

DATA EVERYWHERE
• The C-Span Archive is a Big Data repository• Social and Political Big Data• Captures not just words or moving images
but INTERACTIONS
BRIAN LAMB SCHOOL OF COMMUNICATION
AN INTERACTION REPOSITORY
• The C-Span archive captures who said, what, to whom
• Sender Message Receiver• Concatenated, such chains of interaction
become SOCIAL NETWORKS OF DEBATE

COMMUNICATIVE META-DATA
• Each member of the network can be evaluated for his or her role, importance, and impact
• The role, importance and impact can be turned into search and visualization criteria both for the speakers and for what was said
• Meta-data is data that describes the context of the speech-act and can extend the search past tags, keywords, author, or time

SOCIAL NETWORKS – THE BRIEFEST INTRO• Mapping people as members of a network
reveals things that are not immediately apparent
• What is important is not how much you talk to other people, but how central you are in the debate
BRIAN LAMB SCHOOL OF COMMUNICATION
THE IMPORTANCE OF BEING CENTRAL• Centrality
– Simple• How many conversation partners you have• Follow the distribution of contributions
– Complex and subtle• How important are you in the network of
communications• If you were not there, would the network be poorer

THE MAGIC OF BETWEENNESS CENTRALITY
1 is the most central node, although it is not the most directly connected
It might even be a very unimportant (by attributes) node or even ignored
It is potentially a bridge maker and connector

PRACTICE CAPITAL
• Practice: working together within a human space• Co-work ties are practice ties, not necessarily
communicative• Practice ties can be detected via network
analysis• High betweenness in practice space = high
practice capital

HOW DOES THIS MATTER?
• Mapping social conversations as networks
• Reveals the unseen powerbrokers or bridgemakers
• Suggests new information cues and selection criteria for browsing the videos
• Facilitates a new kind of “data journalism”

AN EXAMPLE: JOINT SELECT COMMITTEE ON BUDGET DEFICIT REDUCTION HEARINGS • November, October 2011
• 17 speakers representatives, senators, former presidential administration staffers/players
