  6. 6. Representing Social Networks  Graphs  Nodes  Representing resources in a business process  Arcs  Representing relations between resources  Weighted version 6 a b c 3 2 1 2 2
  7. 7. Problem 7Increasing the level of abstraction
  8. 8. How they are represented 8 a b c 3 2 1 2 2 a b c a (outgoing)=2+3 = 5 total outgoing = 10 a outgoing contribution = 50% c (outgoing)=2+1 = 3 c->c = 2; 2/3 in total c->a=1; 1/3 in total no a->c
  9. 9. Dealing with the complexity  How to support?  Show/hide parts of the graph  Coloring nodes and edges  Labeling nodes under user control  supporting user interactions e.g. through mouse  Design choices:  Interactivity  Selective hints  Colors 9 a b c
  10. 10. Implementation 10
  11. 11. Evaluation  BPI Challenge 2015 log file  Compared with traditional visualization approach  Studied by four cases for four different metrics  Pros:  Resource Involvement  Association direction  Association contributions  Special nodes  Resource abstraction  Association strength  Cons:  Isolation limit 11
  12. 12. Case 1: working together  Resource Involvement  how much each resource is contributed  Association direction  the dominant direction in a relation between two nodes  Association contributions  to identify and compare the degree of contribution of each node in a relation  Special nodes  e.g. only initiate the work 12
  13. 13. Case 2: Handover of Works  Resource abstraction  facilitates identifications of resources with higher contribution degree in compare to those who has very small contributions to others 13
  14. 14. Case 3: subcontracting  Isolation limit  does not show nodes which do not have any relation to others 14 No relation with others
  15. 15. Case 4: Similar Task  Association strength  enables comparison of relations between nodes 15
  16. 16. Future work  Apply on more real log file in an accessible organization  Usefulness and Usability  Performed in workshop  The data will be analyzed 16
