I recently listened to a podcast on Pickering's human-intensive computing for processing astronomical data. Here is a wiki page that contains an overview and photograph from 1890: http://en.wikipedia.org/wiki/Harvard_Computers I am seeking diagrammatic workflow models of the types of computation that occurred under Pickering's direction, but more generally, any articles or texts that contain such diagrams for human computing. I am familiar with modern formalisms such as BPMN: http://www.bpmn.org/ in which business workflows might be formalized. I also have read Grier's excellent book: http://www.amazon.com/When-Computers-Human-David-Grier/dp/0691091579/ref=sr_1_1?ie=UTF8&qid=1429392009&sr=8-1&keywords=when+computers+were+human The history and cultural context is interesting to me, and most appropriate for engaging readers, however, the main end-point in this story-telling process, for me, is for people to appreciate the path toward the diagrammatic formalisms with their nodes, merges, branches, and connections. If I need to, I can embark on a path toward creating some models with the written historical accounts as a guide, but I thought that checking here would be the best starting location in this quest for diagrammatic evidence. -paul Paul Fishwick, PhD Chair, ACM SIGSIM Distinguished University Chair of Arts & Technology and Professor of Computer Science Director, Creative Automata Laboratory The University of Texas at Dallas Arts & Technology 800 West Campbell Road, AT10 Richardson, TX 75080-3021 Home: utdallas.edu/atec/fishwick Lab Blog: creative-automata.com SIGSIM Blog: modelingforeveryone.com
