5.~ RELATED WORK
</SectionTitle>
    <Paragraph position="0"> A number of papers related the the topics treated here have appeared in recent years. Many are listed in \[8\] which also provides some ideas on the generation of scene descriptions. This work has been pervasively influenced by the ideas of Bill Woods on &amp;quot;procedural semantics&amp;quot;, especially as presented in \[9\].</Paragraph>
    <Paragraph position="1"> Representations for large-scale space (paths, maps, etc.) were treated in Kuipers' thesis \[I0\]. Novak \[11\] wrote a program that generated and used diagrams for understanding physics problems. Simmons \[12\] wrote programs that understood simple scene descriptions involving several known objects. Inferences about the causes and effects of actions and events have been considered by Schank and Abelson\[13\] and Rieger\[14\].</Paragraph>
    <Paragraph position="2"> Johnson-Laird\[15\] has investigated problems in understanding scenes with spatial locative prepositions, as has Herskovits\[16\]. Recent work by Forbus\[17\] has developed a very interesting paradigm for qualitative reasoning in physics, built on work by deKleer\[18,19\], and related to work by Hayes\[20,21\]. My comments on pronoun resolution are in the same spirit as Hobbs\[22\], although Hobbs's &amp;quot;predicate interpretation&amp;quot; is quite different from my &amp;quot;analog spatial models&amp;quot;. Ideas on the adaptation of prototypes for the representation of 3-D shape were explored in Waltz \[23\]. A effort toward qualitative mechanics is described in Bundy \[24\]. Also relevant is the work on mental imagery of Kosslyn &amp; Shwartz\[25\] and Hinton\[26\].</Paragraph>
    <Paragraph position="3"> I would like to acknowledge especially the helpful comments of Ken Forbus, and also the help I have received from Bill Woods, Candy Sidner, Jeff Gibbons, Rusty Bobrow, David Israel, and Brad Goodman.</Paragraph>
