Learner’s perspective:Continuous personal DevelopmentRecognition and portabilityOf learning achievements
Socio-economic Systems :Market take-up
Social inclusion
The Six Prolearn Vision Statements
“Everyone should be able to learn anything at anytime at anyplace”
(personalization – adaptation)
“Learning as a means to support and enhance work performance”
“Promote innovation and creativity and entrepreneurship”
“Learning as a means to increase employability”
(flexibility and survivability of employees)
“Socio-economic systems – market take up”
“Access to professional learning for all – extending the knowledge based society”

Self-regulated Life-long Learning
Dynamic perspective on communities Defining disturbances (Troll) Analyzing communities Application of patterns(Troll) Reflecting models according
to the reality Adapting reflected

CoP Dimensions
Mutual engagement(ME) If you are aware of "what matters" in the scope of a community your engagement is enabled
Joint enterprises(JE) CoPs and theirs members can follow the situations happeningaround them and because of them
Shared repertoire(SR)Members represent community knowledge

Prolearn MediaBase – the Repository of Web-based E-Learning Resources
Data management: Database and crawlersMailWatcher refinement for Pattern Analysis thread identification script
– reply_to field– subject field22% of thread reduction
Data cleaning script for thread content– No HTML tags and technical data– No duplicates (Levenshtein, 1969)
Semantical monitoring32 word categories(4500 words)– psychological constructs– 7 personal concern– 3 paralinguistic dimensions

Hierarchical ClusteringResults
Question-answer community– dyadic and sequent communications– “insight” and “discrep” words – the query-
explanation nature
Disputative community– reply-sender– “explanation”, “disagreement” and “quarells” –
the discussion nature

Conclusions & Outlook
E-Learning communities as CoP Monitoring means (structure + semantics) Modelling hypotheses with Hierarchical Clustering and Factor
Analysis
Influence of the analysis on the learning process Application of linguistic techniques on the semantic analysis Methods of self-modelling of CoP Recommendations in Life-long Learning based on game-
