I am quite familiar with Winograd's work as a founding contributor to computer mediated linguistics, and think the following changes to Wikipedia on this page, and one other, will provide a more accurate and defensible history.
In this article the 'conversation-for-analysis' reference should be identified as Winograd Flores' refinement of speech act theory in the context of organizational communication. speech act theory already has a wikipedia entry, and contemporary articles about the COORDINATOR project framed it as a 'speech act theory' project.
There are copious references on the web that support this: simply google 'speech act theory winograd'
A few examples will suffice: http://www.scils.rutgers.edu/~aakhus/lap/Twitchell%20et%20al%20-%20SAT%20for%20classification.pdf provides a good overview of the field.
http://faculty.arch.usyd.edu.au/kcdc/journal/vol3/dcnet/avarena/text_5.html the slide is titled 'Speech-Act-Based Protocols in Computer-Mediated Collaborative Design' - the Winograd-Flores approach.
I also feel that in the Speech Act Theory article on wikipedia, the 'In Computer Science' portion should reference this work as it was the most prominent and groundbreaking approach in that era.
I am reluctant to edit either entry directly, but if I get a followup to this I will do so.
