Career and research
Halfaker is known for his research[12][13] about the decrease in the number of active editors on Wikipedia.[14][15][16] He has said in autumn 2013 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) in 2015, used to identify vandalism on Wikipedia and distinguish it from good faith edits.[22][23]
