  6. 6. Table Pool all the tags in the centre of the table, and read them all. Staple similar tags together, and choose one marker tag for the group. Example: create, creativity and creation
  7. 7. Individual Next, individually, make tagsets: write down marker tags that belong together according to you
  8. 8. One-to-one Match on similarity with everyone at the table A = total number of used cards = 5 + 4 = 9 B = number of piles which have both your colours = 1+1=2
  9. 9. One-to-One Match on dissimilarity with everyone at the table Ex: Overlapping tagsets, with overlap 2: [learning, writing, reading] [learning, network, writing, blog, wiki]

  11. 11. What did we do? Content Relevance Experience of Breakdown Desire to Connect Similarity matching or Dissimilarity matching?
  12. 12. Method: User profiles • Scoop.IT profiles as the starting point for tagsets • Selection on the basis of Scoop.IT posts with comments • Keyword extraction + stemming
  13. 13. Method:Matching • based on Similarity • based on Dissimilarity

Method: User Evaluation 1.Content Relevance: The Scoop.IT contains new and relevant content for me 2.Experience of Breakdown: This Scoop.IT feed makes me re-assess my thoughts about this topic 3.Desire to Connect: I would like to engage in a discussion with the curator of this Scoop.IT feed
  15. 15. Results 1.Experience of Breakdown strongly correlates with Desire to Connect If you feel you have learnt something from someone, you very likely want to connect 2.Matching on dissimilarity is better at predicting Experience of Breakdown
