Input File Format

Data graph file format is a text format to store a directed temporal data graph.

• The first line of the file should be "t # ID".
• Following lines of "v vertex-ID vertex-label" indicate the vertices in the graph.
  • The vertices should be written in the file in ascending order of their IDs, and a vertex ID should be in [0, #vertices - 1].
• Edges are represented as follows:
  • Following lines of "e source-ID destination-ID source-port destination-port edge-label sec msec" indicate the edges in the graph for Netflow.
  • Following lines of "e source-ID destination-ID edge-label sec" indicate the edges in the graph for Wikitalk and Superuser.

Query graph file format is a text format to store a directed temporal query graph.

• The first line of a graph should be "t # s ID".
• Following lines of "v vertex-ID vertex-label" indicate the vertices in the graph.
• Edges are represented as follows:
  • Following lines of "e source-ID destination-ID edge-label source-port destination-port" indicate the edges in the graph for Netflow.
  • Following lines of "e source-ID destination-ID edge-label" indicate the edges in the graph for Wikitalk and Superuser.
  • The ID of the $i$-th edge in the file is $i-1$.
• Following lines of "b edge-ID1 edge-ID2" indicate that the strict partial order edge-ID1 $\prec$ edge-ID2 holds.
