In computer science, a knowledge base (KB) is a set of sentences, each sentence given in a knowledge representation language, with interfaces to tell new sentences and to ask questions about what is known, where either of these interfaces might use inference. [1] It is a technology used to store complex structured data used by a computer system.
In epistemology, knowledge ascription is the act of attributing knowledge to someone, expressed in sentences like "Sarah knows that it will rain today". [106] According to invariantism, knowledge ascriptions have fixed standards across different contexts. Contextualists, by contrast, argue that knowledge ascriptions are context-dependent.
Knowledge is an awareness of facts, a familiarity with individuals and situations, or a practical skill. Knowledge of facts, also called propositional knowledge, is often characterized as true belief that is distinct from opinion or guesswork by virtue of justification. While there is wide agreement among philosophers that propositional ...
Knowledge functions (e.g., capturing, organizing, and providing access to knowledge) are performed by technical staff, to support knowledge processes projects. Knowledge functions date from c. 450 BC, with the Library of Alexandria, [dubious – discuss] but their modern roots can be linked to the emergence of information management in the ...
The notion of knowledge seems to be governed by the principle that knowledge is factive: (KF): If the sentence ' P ' is known, then P (where we use single quotes to refer to the linguistic expression inside the quotes and where 'is known' is short for 'is known by someone at some time').
Knowledge representation (KR) aims to model information in a structured manner to formally represent it as knowledge in knowledge-based systems. Whereas knowledge representation and reasoning ( KRR , KR&R , or KR² ) also aims to understand, reason and interpret knowledge.
Descriptive knowledge – also called declarative knowledge or propositional knowledge, it is the type of knowledge that is, by its very nature, expressed in declarative sentences or indicative propositions (e.g., "Capybaras are rodents", or "It is raining"). This is distinguished from what is commonly known as "know-how" or procedural ...
[9] [7] Sentences may either be clearly acceptable or clearly unacceptable, but there are also sentences that are partially acceptable. Hence, according to Sprouse, the difference between grammaticality and acceptability is that grammatical knowledge is categorical, but acceptability is a gradient scale.
