In this section, we present our empirical evaluation on the accuracy
and usefulness of GraPacc.We implemented GraPacc as an Eclipse's
plug-in supporting code completion for Java programs. We do evaluation
on both accuracy and usefulness of Grapacc.
The evaluation results show that, GraPacc can achieve up to 95%
precision, 92% recall, and 93% f-score in code completion for automatic
The result also shows that, with GraPacc, human subjects were more
productive because GraPacc can help completing more code during
programming. Their resulting code with GraPacc had higher quality and
was less buggy.
