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
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

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
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
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
Case 3: subcontracting Isolation limit
does not show nodes which do not have any relation to others
14
No relation with others
Case 4: Similar Task Association strength
enables comparison of relations between nodes
15
Future work Apply on more real log file in an accessible
organization Usefulness and Usability
Performed in workshop The data will be analyzed
