Thanks for the feedback! Our "AST visitor" approach is currently not very different compared to existing methods. However, we store the whole AST (including earlier version of the code) in a graph for fast retrieval and add a lot of context information to each vertex in the code tree. Having the code patterns and faulty code in a database, we can make use of user-feedback to (semi-)automatically improve our code patterns for a given error using example-based learning. In that sense the algorithm is much more adaptable than existing technologies.
