American computer scientist
Aaron Halfaker (; born December 27, 1983) is principal applied scientist at Microsoft Research .[1] [7] [2] He previously served as a research scientist at the Wikimedia Foundation until 2020.[8] [9] [10]
Education
Halfaker earned a Bachelor of Science degree 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 Diana Johnson.[11] He subsequently earned a PhD in computer science from the GroupLens Research lab at the University of Minnesota in 2013.[3]
Career and research
Halfaker is known for his research on Wikipedia [12] [13] and the decrease in the number of active editors of the site.[14] [15] [16] He has said that Wikipedia began a "decline phase" around 2007 and has continued to decline since then.[17] [18] Halfaker has also studied software agents (bots) on Wikipedia,[19] and the way they affect new contributors to the site.[8] While a graduate student he developed a tool for Wikipedia editing called Snuggle with Stuart Geiger. Snuggle tackles vandalism on Wikipedia and highlights constructive contributions by new editors.[20] [21] He has also built an artificial intelligence (AI ) service called Objective Revision Evaluation Service (ORES), used to identify vandalism on Wikipedia and distinguish it from good faith edits.[22] [23]
