Knowledge is what is known. Like the related concepts truth, belief and wisdom. There is no single definition of knowledge on which scholars agree, but rather numerous theories and continued debate about the nature of knowledge. Knowledge acquisition involves complex cognitive processes as perception, learning, communication, association and reasoning. The term knowledge is also used to mean the confident understanding of a subject, potentially with the ability to use it for a specific purpose.

[edit] Defining knowledge

The definition of knowledge is a live debate for philosophers. The classical definition, found in Plato[1], has it that in order for there to be knowledge at least three criteria must be fulfilled; that in order to count as knowledge, a statement must be justified, true, and believed. Some claim that these conditions are not sufficient, as Gettier case examples allegedly demonstrate. There are a number of alternatives proposed, including Robert Nozick's arguments for requirement that knowledge 'tracks the truth' and Simon Blackburn's additional requirement that we do not want to say that those who meet any of these conditions 'through a defect, flaw, or failure' have knowledge. Richard Kirkham suggests that our definition of knowledge requires that the believer's evidence is such that it logically necessitates the truth of the belief. In contrast to this approach, Wittgenstein observed, following Moore's paradox, that one can say "He believes it, but it isn't so", but not "He knows it, but it isn't so". [2] He goes on to argue that these do not correspond to distinct mental states, but rather to distinct ways of talking about conviction. What is different here is not the mental state of the speaker, but the activity in which they are engaged. For example, on this account, to know that the kettle is boiling is not to be in a particular state of mind, but to perform a particular task with the statement that the kettle is boiling. Wittgenstein sought to bypass the difficulty of definition by looking to the way "knowledge" is used in natural languages.


[edit] Knowledge management

Knowledge management seeks to understand the way in which knowledge is used and traded within organisations and treats knowledge as self-referential and recursive. This recursion means that the definition of knowledge is in a state of flux. Knowledge management treats knowledge as information within some context. Knowledge in this context consists of information augmented by intentionality (or direction). This conception aligns with the DIKW model, which places data, information, knowledge and wisdom into an increasingly useful pyramid. The main objective of knowledge management is to ensure that the right information is delivered to the right person just in time, in order to take the most appropriate decision. In that sense, knowledge management is not interested to manage knowledge per se, but to relate knowledge and its usage. This leads to Organizational Memory Systems.

[edit] Situated knowledge

Situated knowledge is knowledge specific to a particular situation. Imagine two very similar breeds of mushroom, which grow on either side of a mountain, one nutritious, one poisonous. Relying on knowledge from one side of an ecological boundary, after crossing to the other, may lead to starving rather than eating perfectly healthy food near at hand, or to poisoning oneself by mistake. Some methods of generating knowledge, such as trial and error, or learning from experience, tend to create highly situational knowledge. One of the main benefits of the scientific method is that the theories it generates are much less situational than knowledge gained by other methods. Situational knowledge is often embedded in language, culture, or traditions. Critics of cultural imperialism argue that the rise of a global monoculture causes a loss of local knowledge.

[edit] Partial knowledge

A discipline of epistemology is focused on partial knowledge. It states that in most of realistic cases, it is not possible to have an exhaustive understanding of an information domain, but that we have to live with the fact that our knowledge is always not complete, that is, partial. Most of real problems have to be solved by taking advantage of a partial understanding of the problem context and problem data. That is very different from the typical simple math problems that we solve at school, where all data are given and we have a perfect understanding of formulas necessary to solve them.

[edit] Sociology of knowledge

Aspects of knowledge exhibit a social character. For instance, knowledge is a form of social capital. Sociology of knowledge examines the way in which Society and knowledge interact. Through experience, observation, and inference, individuals and cultures gain knowledge. The spread of this knowledge is examined by diffusion. Diffusion of innovations theory explores the factors that lead people to become aware, try, and adopt new ideas and practices -- this can help to explain development of knowledge.

[edit] Quotes

  • Knowledge is "information combined with experience, context, 
 interpretation, and reflection. It is a high-value form of information
 that is ready to apply to decisions and actions." T. Davenport et al.,
 1998
  • "Explicit or codified knowledge refers to knowledge that is transmittable 
 in formal, systematic language. On the other hand, tacit knowledge has a
 personal quality, which makes it hard to formalize and communicate." I.
 Nonaka, 1994.
  • "Knowledge as the human expertise stored in a person?s mind, gained 
 through experience, and interaction with the person?s environment."
 Sunasee and Sewery, 2002.
  • "Knowledge is a physical, mental or electronic record of relationships 
 believed to exist between real or imaginary entities, forces and
 phenomena." Worthington, 2005.
  • "the insights, understandings, and practical know-how that we all possess 
 ? is a fundamental resource that allows us to function intelligently."
 Wiig, 1996.
  • "knowledge is information evaluated and organized by the human mind so 
 that it can be used purposefully, e.g., conclusions or explanations."
 Rousa, 2002.
  • "Knowledge is... a mental grasp of a fact(s) of reality, reached either by 
 perceptual observation or by a process of reason based on perceptual
 observation." Rand, 1967.

There are numerous type of knowledge divided according to its functions and its carrier systems (for example, management knowledge, manager knowledge).
