  5. Using Knowledge • What do we want when we look for information or knowledge? • answers, not documents! • current retrieval systems identify documents that may or may not contain the answer • irrelevant documents • partial answers • multiple answers • inconsistent, wrong context, …

  6. Current Usage of Retrieval Systems • tools to identify potentially relevant documents • formulation of questions as unnatural queries • either simplistic sets of keywords, or complex expressions • ranking of retrieved documents according to obscure criteria • re-formulation of queries to influence ranking • mostly batch processing • submit query • wait • view result

  7. Better Usage of Retrieval Systems • provide answers to questions • find the right information fast • analyze information, combine it into easily digestible formats • summarize longer documents, sets of related documents • relate it to decisions to be made

  10. Objectives

  11. Knowledge Usage in Context • terminology • dissemination, utilization, diffusion, technology transfer • knowledge dissemination and utilization • traditional model • conceptual and instrumental use • related terms • knowledge use as learning process • knowledge life span • usefulness and accessibility of knowledge • knowledge life cycle • activities dealing with knowledge throughout its useful life

  12. What is Knowledge Utilization? • no clear definition • often used interchangeably with • knowledge dissemination • knowledge transfer • knowledge usage • usually assume two aspects • distribution of knowledge, information, or products • incorporation of conceptual or instrumental use of knowledge into relevant activities

  13. Knowledge Dissemination and Utilization • due to a number of factors, existing knowledge is not used effectively • driven by the dissemination side (researchers), rather than the knowledge use side (practitioners) • finding practical applications of knowledge is often left to potential users • lack of coordinated knowledge utilization activities • ad hoc dissemination models, very few attempts at systematic approaches to utilization • cumbersome accessibility • finding and accessing knowledge has been the domain of specialists (librarians, consultants)

  14. Dissemination Types • spread • one-way diffusion or distribution of knowledge and information • choice • users actively seek and acquire knowledge from established or alternative sources • users learn about their options • exchange • interactions between people • multi-directional flow of knowledge and information • implementation • technical assistance, training, interpersonal activities [NCDDR 1996]

  15. Extension Model of Knowledge Use • rational, linear conception of the process of knowledge utilization • knowledge is packaged and moved from one place to another • based on the assumption that knowledge can be arranged into definable, useable units that can be transmitted easily • “getting the word out” • based on the hope that potential users will hear about it, and be willing and capable to utilize it • does not reflect the use of knowledge in many situations [NCDDR 1996]

  16. Complex Model of Knowledge Use • the process usually is not rational nor linear • complex • multiple sources, multiple media and paths of delivery • interdependencies between individual knowledge items • context may be critical • transactional • may involve transactions between source (expert) and user • dependent on the background of potential users • pre-existing knowledge, beliefs, experiences • the user is involved in the usage process • problem-solver • constructor of a personal knowledge base [NCDDR 1996]

  17. Knowledge Usage • conceptual use • changes in levels of knowledge, understanding, or attitude • instrumental use • changes in behavior and practice • strategic use • manipulation of knowledge to attain specific goals • power, profit, political gain [NCDDR 1996]

  18. Knowledge Usage Metaphors • “tabula rasa” • the learner’s mind is an empty slate upon which people “in the know” impress knowledge • learner as a sponge • soaking up knowledge, largely without filtering or processing • brain as a computer • processes information in a systematic fashion as it is received from outside sources

  19. Knowledge Use as Learning Process • role of knowledge • dynamic set of understandings influenced by its originators and its users • role of the learner • actively filters and shapes knowledge • integration into existing knowledge • constructs models of the the environment • explanations to make sense of the world • pre-existing (mis-)understandings may have to be changed • they result in discrepancies of the mental model [NCDDR 1996]

  20. Dimensions of Knowledge Utilization • dissemination source • originator of information • initiator of dissemination • content • new knowledge • supporting information • dissemination medium • packaging and transmission of knowledge • user • person or organization to receive and apply the knowledge [NCDDR 1996]

  21. Knowledge Life Span [Kaplan 1997]

  22. Knowledge Life Cycle [Kaplan 1997]

  23. Utilization of Knowledge Assets [Konno 2000]

  24. Knowledge Usage Issues • selection of knowledge • composition of knowledge • merging of knowledge items • modification of knowledge • modification of system aspects • preservation of consistency • user motivation
