Inspector for computed relevance messaging

In a system including computational devices connected by a communications network, said system comprising a communications apparatus for linking an information provider to information consumer, said communications apparatus comprising specific units of advice to be shared, digital documents conveying said advice, an advice provider for broadcasting said advice in the form of advisories, an advice consumer for receiving said advisories, wherein advisories are broadcast over said communications network from said advice provider to said advice consumer, a communications protocol for narrowly-focused targeting of said advisories to said advice consumer by automatically matching advisories with an advice consumer for whom said advisories are relevant, and an inspector dispatcher associated with an advice client computer for continually performing relevance determination, wherein said relevance determination is driven by a database of relevance clauses which can be continually evaluated, at least one inspector, comprising:

• an inspector library and associated methods for evaluating subexpressions with said at least one inspector;
• wherein said inspector library contains executable code which is invoked by said inspector dispatcher as part of said relevance determination process;
• and
• wherein said inspector performs any of mathematico-logical calculations, executes computational algorithms, returns the results of system calls, accesses the contents of storage devices, and queries devices or remote computers.
