6. Representing Social Networks
 Graphs
 Nodes
 Representing resources in a
business process
 Arcs
 Representing relations
between resources
 Weighted version

7Increasing the level of abstraction

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. 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

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. 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. 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. Case 3: subcontracting
 Isolation limit
 does not show nodes which do not
have any relation to others
14
No relation with others

15. Case 4: Similar Task
 Association strength
 enables comparison of relations
between nodes
15

16. Future work
 Apply on more real log file in an accessible
organization
 Usefulness and Usability
 Performed in workshop
 The data will be analyzed
