The original 1969 paper by McCarthy and Hayes defining frame is here: http://www-formal.stanford.edu/jmc/mcchay69.pdf http://www-formal.stanford.edu/jmc/mcchay69.pdf In this sense, a frame describes the state of a system in time, like (metaphorically) a film frame. Dennett also uses frames in this sense. (But see https://plato.stanford.edu/entries/frame-problem/ https://plato.stanford.edu/entries/frame-problem/ which incidentally doesn't cite Minsky.) Minsky's 1974 paper doesn't cite McCarthy and Hayes, and he seems to be using frame in a different and more general sense, as a structure for holding data. Whether he had the frame problem in the back of his mind I don't know, but he doesn't address it directly in his paper and I can't find any evidence it was his intention. In any case, frames in the Minsky sense have been used successfully in other systems, such as AM and Eurisko, as well as EMYCIN, and also in the Semantic Web.
