Discovering Program's Behavioral Patterns by Inferring Graph-Grammars from Execution Traces

Chunying Zhao, Keven Ates, Jun Kong, Kang Zhang
2008 2008 20th IEEE International Conference on Tools with Artificial Intelligence  
Taking advantage of graphs' expressiveness and intuitiveness for human cognition, we present a graph-grammar induction approach to discovering program's behavioral patterns by analyzing execution traces  ...  These patterns can be used to reveal the hidden structures of a program, and ease the comprehension of legacy systems.  ...  We adapt SubdueGL's substructure matching algorithm by annotating graphs with temporal attributes since data describing program executions naturally have temporal attributes.  ...
