Michael,
I only have time right now to present a short answer to one of your
questions. More later. (01)

What you need to look for (and 'look at') is the compound word 'look at'
(a phrase or idiom, if you like). In WordNet 'look at' has two definitions: (03)
[WordNet 2.1]
1. (17) consider, take, deal, look at -- (take into consideration for
exemplifying purposes; "Take the case of China"; "Consider the following
case")
2. (6) view, consider, look at -- (look at carefully; study mentally; "view
a problem") (04)
Word combinations will often have meanings that are related to but not
identical to any of the individual words. In the phrases "cat house" and
"house cat" each word has a different sense.

As for " potential murderers”

In the compound word "potential murderer" both "potential" and "murderer"
have exactly the meanings that they have individually. But the combination
has a meaning that is related to each word in a systematic way. The word
"potential" is one of a well-studied set of modifying words like "phony"
"counterfeit", "toy", "pretended", etc., one of whose meanings is to negate
the idea that the entity referred to it a legitimate instance of the
category thus modified. (07)
Consider again the problematic cases you mentioned and see if they
actually illustrate the point you want to make. (08)

I am not an expert but let me try. (014)
In order to understand a sentence, it is not enough to pick the right word
sense. You have to understand the sense and how it can modify other senses.
You need context, background knowledge and the ability for abstraction and
generalization. You need to be able to follow the line of thinking of the
author. (015)
The word much has only one meaning in Wordnet: "a great amount or extent".
Great is defined by Wordnet as "relatively large in size or number or
extent".
How do you get a machine to understand the sentence "I ate much" without the
knowledge that "I" refers to a human and how much humans usually eat ? (016)
Or take the sentence "Soldiers are potential murderers". The sense of
"murderer"
is modified by "potential" to be something completely different. (017)
Or take my own sentence: (018)

How do you get from "put" and "together" to "put together" ? There are many
senses for "looking" in Wordnet but I cannot find the right one. It is not
used literally here. (020)

How about a dictionary without circular definitions ? I do not know of such
a thing and I bet it is not because of ignorance on my part. (022)
The failure of the Cyc project also should be closely related to this
problem.
Maybe the people familiar with Cyc have more and better examples of the
problems you would face. (023)
My opinion is that understanding of natural language is not possible without
true intelligence. It may also be a bit the other way round. (024)
