|October 2016||Ideological Segregation among Online Collaborators: Evidence from Wikipedians|
with , : w22744
Do online communities segregate into separate conversations about “contestable knowledge”? We analyze the contributors of biased and slanted content in Wikipedia articles about U.S. politics, and focus on two research questions: (1) Do contributors display tendencies to contribute to topics with similar or opposing bias and slant? (2) Do contributors learn from experience with extreme or neutral content, and does that experience change the slant and bias of their contributions over time? Despite heterogeneity in contributors and their contributions, we find an overall trend towards less segregated conversations. Contributors tend to edit articles with slants that are the opposite of their own views, and the slant from experienced contributors becomes less extreme over time. The experience...
|June 2012||Collective Intelligence and Neutral Point of View: The Case of Wikipedia|
with : w18167
We examine whether collective intelligence helps achieve a neutral point of view using data from a decade of Wikipedia's articles on US politics. Our null hypothesis builds on Linus' Law, often expressed as "Given enough eyeballs, all bugs are shallow." Our findings are consistent with a narrow interpretation of Linus' Law, namely, a greater number of contributors to an article makes an article more neutral. No evidence supports a broad interpretation of Linus' Law. Moreover, several empirical facts suggest the law does not shape many articles. The majority of articles receive little attention, and most articles change only mildly from their initial slant.
|March 2005||What is the Impact of Software Patent Shifts?: Evidence from Lotus v. Borland|
with : w11168
Economists have debated the extent to which strengthening patent protection spurs or detracts from technological innovation. In this paper, we examine the reduction of software copyright protection in the Lotus v. Borland decision. If patent and copyright protections are substitutes, then weakening of one form of protection should be associated with an increasing reliance on the other. We find that the firms affected by the diminution of copyright protection disproportionately accelerated their patenting in subsequent years. But little evidence can be found for harmful effects: in fact, the increased reliance on patents is correlated with some positive outcomes for firms.
