__NOTOC__
[[FollowLinksForMoreInformation]] is the general practice of performing
web retrieval on URIs in a knowledge base to obtain more knowledge.
It might also be called "Inclusion During Query Answering" and is
sometimes loosely called [[FollowYourNose]].    It gives rise to
[[SelfAnsweringQuestion]]''''''s and the [[SelfDescribingWeb]].  From
a multi-agent system design angle, this sometimes looks like
[[PullTheDefinition]].

There are many specific practices one might follow here, such as only
following links in the RDF predicate position, or only following
rdfs:seeAlso links; see [[LinkProperties]] for discussion. The myriad options 
have different results in two dimensions:

# '''Performance.'''   Following all the links may take too long or
   produce too much data, so the question is which links to follow first
   or follow at all.  From this angle, links indicate ''relevance'', 
   pointing out some information which (true or false) is probably more
   interesting than other information of unknown veracity.

# '''Trust.'''  What to do with any knowledge you
   gather?   Do you simply consider it true since [[UseImpliesConsent]] (There are degrees of consent and trust. Trust is not boolean. ''guest''), do
   you consider it provisionally true in some sense, do you consider some of it true based on what kinds of links were followed, ...?

Some options:

   Just use the complete [[WebClosure]], including everything, trusting
   everything. 

   The [[DefinitionalWebClosure]] is more restricted, but is currently
   untested. 

   [[DocRulesClosure]] is another experimental approach.

Closer to applications, we can imagine this might manifest as:

   All [[SemanticWeb]] applications might issues WARNINGS about any logical inconsistencies
   found among the closure of nearby documents.

   Query anwering servers might offer answers coming from the deductive closure of
   nearby documents, but qualify such answers as second-rate; users/clients could
   ask for details in the proof (as with any other answer).
