Abstract
We motivate how personal knowledge models can make knowledge workers more productive.
The external representation can help him to tackle typical cognitive limits.
They do so by allowing a knowledge worker to efficiently and effectively model her or his personal knowledge in a mix of informal and formal knowledge.
As a result, more knowledge can be re-used cheaper and hopefully more complex problems can be tackled.

More Productive Knowledge Workers
The knowledge-based organisation is no more effective than the sum of its knowledge workers' effectiveness. (Davenport)
Knowledge management is shifting from a focus on enterprise productivity to a focus on individual knowledge worker productivity (Gartner 2002)
Increasing the individual knowledge worker productivityincreases the productivity of the organisation

Basic unit: A Knowledge Cue, ``a note to self'‘
A knowledge cue is any kind of storable symbol, pattern or artefact, created with the intent to be used by its creator, to re-evoke a previously experienced mental state (activated
knowledge), when viewed or used otherwise. Does it contain knowledge?
Physical cues: Limited modifiability and scalability Digital knowledge cues

Knowledge cues can vary in size and ...
Degree of structure Heiko works for the FZI. (Plain text)
– Query: „Heiko“ (Full-text search) Heiko works for the <company>FZI</company> (XML)
– Query: „//company“ (XPath) Degree of formality
(Heiko, works-for, FZI), (FZI, is located in, Germany) (RDF)– Query: „?who, works-for, ?company.
?company, located-in, Germany“ (SPARQL)
More structure, more formality
more automatic processing (queries, transformations)

Personal Knowledge Model
A personal digital knowledge model is a digital artifact, which represents a set of knowledge cues.
The knowledge cues can vary in size, structuredness and degree of formality.
A knowledge cue is either (a) a piece of content, containing
– plain text, – semi-structured text, or– arbitrary binary content such as images or desktop objects, or
(b) a connection between other knowledge cues. Such connections can be
– unspecified relations, – directed hyperlinks and – formal statements.

Requirements
Unified Model Import from a number of existing formats
Step-wise Formalisation Text more and more structured text Links typed links semantically typed links
Knowledge Model Refactoring Note: Ignored in many approaches and research papers
Knowledge Model Maintenance System should help user in removing or updating old
knowledge

Summary. The idea is to• Amplify the abilities of the individual
to work better with knowledge
• by managing a set of knowledge cues
• in a unified knowledge model with
• step-wise formalisation
• to let the user find the sweet spot between effort and benefit.
