Long Tail of learning [BrAd08]: many niches- What are properties of communities?- Can a community self-reflect in the Long Tail? - How the community express purposes and goals?- What happens if goals of the community are fulfilled?
Motivation
Niches are: learning partners, documents, media, communities

Community intentions -> community mission (Joint Enterprises (JE))
Community information -> knowledge repository (Shared Repertoire (SR))
Interactions between CoP and Learner -> Mutual Engagement (ME)
[ROLE Deliverable 7.1-7.2]
Combination of Community of Practice and Activity Theory shows common aspects

TeLLNet Use Cases1. eTwinning Database: collaborative social networks2. ROLE Test-beds: activity-based social networks
exploring of learning activities utilizing widgets performed by 5 test bed partners from different areas
3. Wikipedias: author/article networks with small world phenomenon– 10x106 contributors, 8,5x107 pages and 2,1x108 revisions collected over 7 years– Correlations between immigration flow and Wikipedia contributors– Similar behavior of editing / revising contributor activities different Wikipedias
4. Mediabase 2.0: media networks gathered by Community Information Systems Group
– 563,130 actors gathered starting from Oct. 10th, 2005 until today – Social network measures and patterns in the course of time– Named entity recognition using Linked Data Initiative

Simulation 65 Teacher profiles including:
– type of a school (secondary, primary) – location (German speaking countries)– language family– themes of teaching (Math, Physics)– tools used (Skype, Matlab, Photoshop)..
Two teachers are connected if their profiles match each other – until a Nash Equilibrium is reached
TeLLNeteTwinning Database: collaborative social networks
– 135,351 teachers and 36,099 connections (projects,twin, comments)– game-based simulation of network formations– competence management of learners using Social Network Analysis

TeLLNet Future Work Consolidation for theoretical framework Modeling:
– how does the Self-modeling phase contribute to Self-analysis phase and vice versa
– assessment and utilizing of learners‘ competences in modeling phase
Experiments: – compare different approaches of analysis of community actors – detection of communities, their properties and components
