Agenda

 3.2 PKM Tools


The most important contribution of management in the 20th
century was to increase manual worker productivity fifty-
fold.
The most important contribution of management in the 21st
century will be to increase knowledge worker productivity –
hopefully by the same percentage. […]
The methods, however, are totally different from those that
increased the productivity of manual workers.
Peter F. Drucker, 1958


Why Personal Knowledge Management?

Human long-term memory has giant capacity
huge amounts of information are stored
memory retrieval is the bottleneck

Working memory is very limited
Only 7±2 items can be held in working memory simultaneously
(G. A. Miller, 1956)
Dealing with complex subjects, this is a problem…


Complex Problem Solving

networked thinking
Frederic Vester “The Art of Networked Thinking”
Dietrich Dörner “The Logic of Failure”
Heinz v. Foerster (Cybernetik)
reducing complexity
clustering, modularisation
pattern recognition
abstraction
activating and relating to prior knowledge


Cognitive Adequacy

Evolution did not optimise our brains for the kinds and
amounts of knowledge we deal with nowadays.


Cognitive Adequacy

To support knowledge work, we need
methods and techniques
mnemonics (memory techniques)
meta cognition (thinking about thinking)
meditation (practicing the mind)

cognitive tools
“Gedankenstützen”, “Denkwerkzeug”

reduce cognitive load / cognitive overhead

Model by Max Völkel (http://xam.de/ ) based on: Marc E. Nissen, 2006, WM Potsdam


Re-Use Your Own Knowledge

Externalisation Internalisation

Note-taking is communication with yourself


Degrees of Formality

“Knowledge Cue” (Wissenshinweis)
undetailled, degree of structuredness/explictness/formality detailed,
raw, exact,
short, explicit,

Cost and Benefit of PKM

• Total costs C = CE + CR
• Benefit B = ?
 Personal KM is always gambling:
 Will I ever need this knowledge again? In what context?

 Is it cheaper to recreate the knowledge? CC < CE + CR
 What value will it have? How much effort to structure and
formalize is justified? B > CE + CR

Status of the Topic

By far less ....
understood
agreed
integrated
heavily researched on
... than other KM areas (groups, organizations, processes, ...)
Nevertheless, central to KM !
Differentiation from surrounding areas a bit fuzzy
eLearning, Skill Management
Personal information management (“PIM”)
Community knowledge management
Personal task and self management


Agenda

 3.2 PKM Tools


Cognitive Tools

Personal knowledge media
representing problems
supporting memory
knowledge modelling
organising resources
 “extracortical organizers of thought” (Vygotsky, 1978)
“We can‟t manage knowledge, only cues to knowledge.”
Knowledge cues are things (symbols, words, artefacts), that help us
reconstruct the original knowledge structures associated with them.
Pictures
Texts
Keywords


Conventional Tools

paper-based tools
calendars
notebooks
sketches
… are well-established
but have shortcomings

especially for complex contents,
computer-based tools have valuable possibilities
full text search / filtering
linking / browsing
zooming
interactive editing / refining
easy sharing / collaborating


PKM Pioneers

MEMEX (1963): (1992)
„enlarged intimate AUGMENT used Zettelkasten for
supplement first hypertext 26 years:
to his memory“ system
„Als Ergebnis längerer
Arbeit mit dieser Technik
[dem Zettelkasten]
entsteht eine Art
Zweitgedächtnis, ein
Alter ego, mit dem man
laufend kommunizieren
kann.“

Zettelkasten
 extensible
 no queries / text search
 no automation


PIM – Personal Information Management

Example of an Outliner (Gliederungseditor)


Example of an Outliner (Gliederungseditor)

OmniOutliner

Outliners can be used …

… as an aid for writing long / complex texts
… as a personal knowledge repository – like a Zettelkasten
… for task/project planning

Task Manager (OmniOutliner)


Personal Wiki Use

using standard (multi-user) wikis online as single user
pro: easy to set up
(Wiki-Farms e.g. pbworks.com, wikia.com, referata.com)
con: no offline use, limited control over personal data

using standard (multi-user) wikis locally
e.g. JSPWiki, (Semantic) MediaWiki
pro: stable, well-known environment, own your data
con: does not (automatically) sync with other devices (e.g. mobile)
con: requires additional software, e.g. a Web server, (L)AMP
personal editions of standard wikis


Personal Wiki Engines

additional features
tree views
drag and drop for external content (images, text, video, …)
OLE – wikis as relational superstructures for desktop documents
faster
con: usually no syncing to other places of use

Voodoo Pad screen shot shows dragged in images


Personal Wikis – Conclusion

Wikis can be used locally as “personal wikis”.
Have proven to be very efficient for PKM
interlinking information units (pages)
backlinks
categories, tags, keywords
full-text search
structured and unstructured contents
scalable (some people have several thousand pages)

But don‟t allow to see overall structure
 no overview


Visual PKM Tools – why?

Our sense of spatial orientation is highly efficient and
automated.
Automated actions do not interfere with conscious tasks.
(Schneider & Shiffrin, 1977)
Using our spatial sense to deal with knowledge helps
orientation in our “knowledge space” very efficiently.
Visual representations are easier turned into mental
models because they bare the structure of the content
matter (see next slide)

Mapping Techniques in Comparison

Mind-Mapping (see T. Buzan)
easy, fast
but vague

Concept Mapping (see J.D. Novak)
expressive, stresses structure
but need more effort

Spatial Hypertext (see F. M. Shipman)
constructive ambiguity
but no explicit relations


why not have maps of maps?
