Personal Knowledge Management

Personal Knowledge

Mind map: [http://yadi.sk/d/f1pfNItl2KXsR]

Knowledge

  • derived from information
  • distilled
  • extracted from sources
  • what one has learned

data/information is not knowledge until we dig the value out of it

Information Literacy

definition

  • ability to know when there’s a need for information
  • to be able to identify, locate, evaluate and effectively use that information
  • for the problem at hand

schemata (Big6)

  • locating
    • basic questions
      • what is known about the topic?
      • what information is needed?
      • where can it be found?
    • finding sources of information
  • selecting/analyzing
    • examining the resources
    • separating useful from not useful
  • organizing/synthesizing
    • selected information is organized
    • knowledge and solutions are developed
    • facts vs opinions
    • comparisons
    • organizing ideas logically
  • creating/presenting
    • presentation to an appropriate audience
    • a paper
  • evaluating
    • critical evaluation of completion
    • was it solved?
    • was the knowledge found?
    • could I do it differently?
    • what was well?

standards

  • information literacy
    • asses information effectively and efficiently
    • evaluate critically and completely
    • use information accurately and creatively
  • independent learner
    • information literate
    • peruses information related to personal interests
    • excellent in information seeking and knowledge generating
  • social responsibility
    • contribute to learning community
    • participates in groups to peruse information and generate knowledge

Knowledge management

KM - making the best use of knowledge

processes

  • acquiring
  • creating
  • sharing

KM

  • cognitive science
  • expert systems, AI
  • knowledge base management systems
  • groupware
  • document managing
  • etc

objectives

  • enhance collaboration
  • capture and store best practices
  • e-learning
  • web-publishing

goals

  • identify
  • create
  • represent
  • distribute
  • enable adoption of
  • insights and experiences
  • and transform it into knowledge

knowledge

  • tacit
    • internal
  • explicit
    • in form that can be communicated to others
  • KM converts knowledge from tacit to explicit

strategies

  • push
    • people publish their note into repository, for further access
  • pull
    • publish per request

Personal Information Management

goal: to ease the process of

  • acquire
  • organize
  • maintain
  • retrieve
  • use

sources

  • documents
  • web pages
  • emails

main idea

  • we always have needed information at hand

Personal Knowledge Management

  • bottom-up approach to Knowledge Management
  • PKM integrates KM and PIM (personal information management)
  • for expanding cognitive capabilities of individuals

process of

  • gather
  • classify
  • store
  • search
  • retrieve
  • share
  • information

Wright’s Model

  • analytical
    • interpretation
    • envisioning
    • application
    • creation
    • contextualization
  • information
    • sourcing
    • assessment
    • organization
    • aggregation
    • communication
  • social
    • collaboration with people
    • development networks
  • learning
    • pattern recognition
    • reflection
    • development of new knowledge

Skills

  • reflection
  • continuous improvement
  • manage learning
    • how to learn
  • informational literacy
    • what is important
    • how to find it
  • organizational
    • categorization
    • taxomonies
  • communication and interaction
  • creativity

Personal Knowledge Base

PKB

  • personal
    • for a particular individual, others should not care
  • knowledge
    • consists of knowledge, not information
  • base
    • consolidated knowledge store
    • easy to access

knowledge capture tools

  • mind mapping
    • diagrams to visually outline information
    • major categories radiate from central node
    • free form
    • spatial layout
    • a tree
    • guidelines - see @ wiki
    • uses
      • generate, visualize, classify ideas
      • aids for students
      • problem solving
      • summarizing
  • concept mapping
    • based on assimilation theory of knowledge
      • newly encountered knowledge must be related to prior knowledge
    • CM depicts these connections graphically
    • links are labeled
      • typically with a verb phrase
  • hyperlink systems
    • non-linear dynamic hyperdocument
    • piece of text linked together
  • note-taking

benefits

  • knowledge generation of formulation
  • knowledge capture
  • knowledge management and retrieval
  • integration heterogenous sources
