We propose an approach called Bug report assignment with topic modeling and heterogeneous network analysis(BAHA) to automatically assign bug reports to developers. Existing studies adopt social network analysis to characterize the collaboration of developers. The networks used in these studies are all homogenous. In real practice of bug resolution, different developers collaborate on different bug reports that makes the homogenous network unable to capture this information. We use heterogeneous network to describe the relations between reporters,bug reports and developers to characterize developers’ collaboration. Experiments on Eclipse JDT pro ject show that BAHA outperforms the state of art methods on automatic bug report assignment.
