Concept Location based on System Dependency Graphs

Software maintenance can be seen as the act of correct errors in the software and/or the addiction of new features. This is one of the most difficult and frequent jobs of a software engineer and one of the most important and expensive parts of software development.Maintaining a software is very complex mainly because before making the change to the program, software engineers need to find the location, or locations, where the changes will be made; in other words, first they need to understand the program. Real applications are always huge and sometimes these programs are old or were written by other person and it is difficult to find the location where the change will be applied. There are various techniques to find these locations minimizing the time spent, but this phase of software development continues to be one of the most expensive and longer.The objective is to combine Program Comprehension techniques like comment analysis and SDG visualization, creating a tool easy to use, that can simplify and decrease the time spent understanding a program.
