Syntactica: Version 1 (for NeXTStep)

Semantica is the manual for a new software application thatallows the user to explore
the semantic structure of language in anengaging, interactive way. The program, which was produced
as part ofa National Science Foundation initiative for improving linguisticsinstruction, is designed
to be used with Syntactica, a tool for studying natural language syntax. Semanticaprovides a simple
graphical interface for creating semantic theories,viewing the truth conditions that those theories
assign to phrase-markerscreated in Syntactica, and for testing those truth conditions in
apictorially represented world. Although designed for use inintroductory semantics courses,
Semantica has features that willappeal to professionals. For example, it can be used as a
"derivationcalculator" in following out complex semantic derivations involvingmany steps and
operations.Manual plus NeXTStep software for PCs and NeXTStationsrunning NeXTStep version 3.2 or
