Actually it comes from your Wikipedia article above...
"information is data in context and with meaning attached"
The Wikipedia article points to the following link to describe the difference between information and data
https://www.diffen.com/difference/Data_vs_Information
"Data - Data is raw, unorganized facts that need to be processed. Data can be something simple and seemingly random and useless until it is organized.
Information - When data is processed, organized, structured or presented in a given context so as to make it useful, it is called information."
That is a function of meaning, structure, and organizationNothing about resolution of uncertainty?
"The uncertainty of an event is measured by its probability of occurrence and is inversely proportional to that. The more uncertain an event, the more information is required to resolve uncertainty of that event."
Information has to be meaningful and understandable by both the sender and the receiver.That the message has to be understandable for the receiver is obvious which also requires that he/it understands the context.
No this is empirical observation.Is this a definition?b. The only observed causal agent (definer and creator) of information is intelligence.
For each of your three examples I was demonstrating how...You post #126 I didn't understand.
a string of alphabetical symbols that have "meaningful non-random structure and organization" contain information and are able to resolve uncertainty.
while
a string of characters, that are not meaningful, are random, and do not have structure and organization do not contain information and are unable to resolve uncertainty.
