Semantic function labels for ardupilot

Hello,
I am using your dataset for my academic project. In this project, I have some queries like “finding functions that do X” (e.g calculates the position of the vehicle). I need labels to define if the Function Y does the task X? I looked if I can use function comments to define this label but it was not helpful. Can you please help what I can do? if there is any documentation that can help or if there is a way we can pay to get this information. Any help would be appreciated. Thanks
