Glossary References
Glossary entries whose definitions form strong interdep-
endencies are grouped together in the following list. The same
glossary entries may be grouped together in different ways at
the end of different chapters, each grouping reflecting the
semantic perspective of each chapter. There will usually be
several other, and often many other, glossary entries that are
not included in the list, and we recommend that the Glossary
be consulted whenever an unfamiliar term is encountered.
We note, in particular, that the nine terms used to refer to the
act of giving a truth value to a statement, listed in the section
The Semantics of Deferred Assertion Time
, are not included in this
list. Nor are nodes in our Allen Relationship taxonomy or our
State Transformation taxonomy included in this list.
