“90-9-1” Rule for Participation Inequality: Lurkers vs. Contributors in Internet Communities Jakob Nielsen’s Alertboxenero 9, 2010
Alertbox, October 9, 2006:
Participation Inequality: Encouraging More Users to Contribute Summary: In most online communities, 90% of users are lurkers who never contribute, 9% of users contribute a little, and 1% of users account for almost all the action. All large-scale, multi-user communities and online social networks that rely on users to contribute content or build services share one property: most users don’t participate very much. Often, they simply lurk in the background.In contrast, a tiny minority of users usually accounts for a disproportionately large amount of the content and other system activity. This phenomenon of participation inequality was first studied in depth by Will Hill in the early ’90s, when he worked down the hall from me at Bell Communications Research see references below.the 90-9-1 rule for participation in an online communityWhen you plot the amount of activity for each user, the result is a Zipf curve, which shows as a straight line in a log-log diagram. User participation often more or less follows a 90-9-1 rule:
- 90% of users are lurkers i.e., read or observe, but don’t contribute.
- 9% of users contribute from time to time, but other priorities dominate their time.
1% of users participate a lot and account for most contributions: it can seem as if they don’t have lives because they often post just minutes after whatever event they’re commenting on occurs.
Getting started with Qualitative Data Analysis SoftwareBelow are links to materials that tell you how to undertake some of the basic activities in qualitative data analysis software such as importing documents and starting projects, coding and its organisation, creating memos, text and code searching, reporting and retrieving information.Many software developers now produce their own teaching materials that cover the basics of the software use. Where this is so the links below are to their materials. In other cases there are links to materials on this site that cover older versions of the software to help those who are still using these versions.

Can We Reinvent the Internet?
Recently, researchers who support “network neutrality” have become worried that the Internet may lose its innovative edge. They are concerned that control could be shifting from the edges of the Internet toward the service providers at the center, which would allow the providers to have “gatekeeper” capacity and would contradict the Internet's “end-to-end” principle (1–3). This core tenet states that control over information flows should take place, to the extent possible, at the end points of the network (4). President Obama supported net neutrality during his campaign (4) and in recent statements (5), and the European Parliament has added net neutrality to its recent telecom bill (6). Taking the end-to-end principle from protocols to users, Jonathan Zittrain has called for maintaining the Internet's “generativity,” the ability of users at the network's end points to create, distribute, and run whatever software code they choose (7). There are good reasons to preserve network neutrality and generativity, but it is unclear whether these are sufficient to ensure continued innovation. The larger issue is what policies are optimal to foster innovation on the Internet?

RDF Gravity is a tool for visualising RDF/OWL Graphs/ ontologies.
Its main features are:
* Graph Visualization
* Global and Local Filters (enabling specific views on a graph)
* Full text Search
* Generating views from RDQL Queries
* Visualising multiple RDF files
RDF Gravity is implemented by using the JUNG Graph API and Jena semantic web toolkit.
