Education and career

Halfaker earned a B.S. in computer science from the College of St. Scholastica in 2006, where he started off as a physical therapy major but switched to computer science after taking a programming class with associate professor Diana Johnson. [7] He later earned a Ph.D. in computer science from the GroupLens research lab at the University of Minnesota in 2013. He is known for his research on Wikipedia and the decrease in the number of active editors of the site. [8] [9] [10] He has said that Wikipedia began a "decline phase" around 2007 and has continued to decline since then. [11] [12] Halfaker has also studied automated accounts on Wikipedia, known as bots, [13] and the way they affect new contributors to the site. [4] While a graduate student, he, along with Stuart Geiger, developed a tool for Wikipedia editing called "Snuggle", the goal of which is to eliminate vandalism and spam, and to also highlight constructive contributions by new editors. [14] [15] He has also built an artificial intelligence engine known as "Objective Revision Evaluation Service" (or ORES for short), used to identify vandalism on Wikipedia and distinguish it from good faith edits.

Gender bias on Wikipedia reflects findings that a dominant majority of volunteer Wikipedia editors, particularly on the English-language site, are male. Also, there are fewer and less extensive articles about women or topics important to women. It figures among the most frequent criticisms of Wikipedia, sometimes as part of a more general criticism about systemic bias in Wikipedia. The Wikimedia Foundation, which runs Wikipedia, agrees with these criticisms and has made an ongoing attempt to increase female editorship of Wikipedia. Edit-a-thons have been held to encourage female editors and increase the coverage of women's topics.

CongressEdits was an automated Twitter account created in May 2014 that tweeted changes to Wikipedia articles that originated from IP addresses within the ranges assigned to the United States Congress. The changes could have been made by anyone using a computer on the U.S. Capitol complex's computer network, including both staff of U.S. elected representatives and senators as well as visitors such as journalists, constituents, tourists, and lobbyists. Previous to this, the best information about what congressional staffers were editing was found in the articles U.S. Congressional staff edits to Wikipedia and Wikipedia:Congressional staffer edits, which are manually updated. CongressEdits has been called a watchdog by NBC News. Twitter suspended the account in October 2018.

Predictions of the end of Wikipedia

Various publications and commentators have offered a range of predictions of the end of Wikipedia. As soon as Wikipedia became well-known—around 2005—one scenario of decline after another has appeared, based on various assumptions and allegations. For example, some claim a degradation in quality of Wikipedia's articles, while others say potential editors are turning away. Others suggest that disagreements within the Wikipedia community will lead to the collapse of Wikipedia as a project.

Artificial intelligence is used in Wikipedia and other Wikimedia projects for the purpose of developing those projects. Human and bot interaction in Wikimedia projects is routine and iterative.

Wikipedia bots are Internet bots which perform tasks in Wikipedia.
