The present disclosure relates to a method for a software development system, the software development system comprising a code repository storing source code. The method comprises: receiving at the code repository an additional code; receiving at one or more documentation repositories documentation information for documenting the source code; generating corpus-based semantic word embeddings for code and documentation words of the source code and the documentation information; using the word embeddings for mapping by the software development system the source code to corresponding documentation; storing the mapping of the source code to the corresponding documentation.
