That is the situation that the term 'ontological commitment' (See Gruber et
al)
was created for. Ontological systems usually require some form of
verification
that the intent provided is the intent understood. Otherwise, is it a
Quality
of Service (QoS) issue. Intent-based systems cannot be trusted
mechanically.
That is why the argument "at Internet scale" is a little misleading.
Systems
that require accurate information to be transmitted, regardless of whether
they are ontological or otherwise, rely on reputation management. This
can be P2P (a sort of trust keiretsu) or managed (a third party vouches
for the reputation of the source), or even ad hoc (some test of credibility
is established for each transaction) or laissez-faire (trust given always
until the other party defects). All rely on identity management.
The problem of sense-making is well-known. Here is the rub: on occasion,
the majority will be wrong and the minority or the one will be right. This
is where pageRanking and other back-link counters fall apart and that is
why the 'superstitious acquisition' problem is wicked. Situation and
context
help but can't fix the problem for all cases. If I ask "Does the earth
revolve around the Sun" in the lifetime of Copernicus, only Copernicus
gives the 'correct' answer but the 'right' answer is 'no' in the time-frame
if authorities ranked by links are the metric. So even combining identity
management (know the answer is from Copernicus) and knowing the situation
(in his lifetime) won't get the correct answer if you ask in the situation.
If you ask "What was the answer in Copernicus' lifetime?", you will get
an answer that is right and correct.

There is a whole other aspect, too. Suppose that you decide that Fred's
credentials are really in order, to what extent can you believe what he
says? A person can be untrustworthy on one or many subjects even though his
identity is well-established.
