<p class="commentary firstcommentary"><a id="SP1_5" class="paragraph-anchor"></a><b>&#167;1.5. </b>Now to fill in the gaps. At this point we have the action name
list as a linked list of all possible lexical matches, but want to
whittle it down to remove those which do not semantically make
sense. For instance, "taking inventory" has two possible lexical
matches: "taking inventory" with 0 parameters, or "taking" with
1 parameter "inventory", and we cannot judge without parsing
the expression "inventory". The list passes muster if at least
one match succeeds at the first word position represented in the
list, which is to say the last one lexically, since the list is
reverse-ordered. (This is so that "taking or dropping something"
requires only "dropping" to have its objects specified; "taking",
of course, does not.) We delete all entries in the list at this
crucial word position except for the one matched.

parameter of the same type. Thus "waiting or taking something" fails
(waiting takes 0 parameters, but we specified one), and so would "painting

that the "doing anything" action is always allowed a parameter (this is

example, in "Kevin taking or dropping something", the operand is "something".
We treat words like "something" specially to avoid them being read as
"some thing" and thus forcing the kind of the operand to be "thing".
