Identifying Information Needs for Program Understanding: an Iterative Approach

Deciding which information is required to help performing a given Program Understanding task is a hard problem. An iterative construction of the solution is a convenient way to address the problem since it allows evaluation of each intermediate solution in order to refine it, and this as often as juged necessary, until a satisfying one is found. In this paper, we show how we iteratively refined and tuned views intended to help understanding the effect of function calls and discuss the effectiveness of the method.
