Data, information, knowledge and wisdom According to Russell Ackof , the content of the human mind can be classified into five categories: Data : is a raw fact (symbols) Information : data that are processed to be useful(giving meaning to data) Knowledge : application of data and information; answers "how“ Understanding : appreciation of "why“ Wisdom : evaluated understanding Data it simply exists and has no significance beyond its existence It can exist in any form , usable or not It does not have meaning by itself A spreadsheet generally starts out by holding data 07/04/2019 AI/CSE 3206 3

Data…..contd 07/04/2019 Information Is data that has been given meaning by way of relational connection This " meaning " can be useful, but does not have to be A relational database makes information from the data stored within it AI/CSE 3206 4

Data…..contd Knowledge It is the appropriate collection of information , such that it's intent is to be useful. Knowledge is a deterministic process. Most of the applications we use (modeling, simulation, etc.) exercise some type of stored knowledge . Understanding is a true cognitive and analytical ability Understanding is an interpolative and probabilistic process Synthesize new knowledge from the previously held knowledge 07/04/2019 AI/CSE 3206 8

Data…..contd Wisdom Is an extrapolative and non-deterministic, non probabilistic process It calls upon all the previous levels of consciousness, and specifically upon special types of human programming (moral, ethical codes, etc.). Most people believe that computers do not have , and will never have the ability to posses wisdom. The following diagram represents the transitions from data , to information , to knowledge , and finally to wisdom. It is called as knowledge hierarchy 07/04/2019 AI/CSE 3206 9

Data…..contd The first four categories relate to the past . Only the fifth category, wisdom , deals with the future because it incorporates vision and design . With wisdom, people can create the future rather than just grasp the present and past . But achieving wisdom isn't easy . People must move successively through the other categories . The most important is, it is very hard to represent wisdom with a computer system 07/04/2019 AI/CSE 3206 11
