For many users and especially for beginners it is hard to quickly find appropriate categories for files. To support the user i suggest to develop an algorithm that is suggesting such categories by checking the filename, the description and location of the file against already available files, categories and galleries in Commons. Even Wikidata and Wikipedia could be included. Having such an algorithm the UploadWizard could be enhanced to suggest categories for uploaded files. Furthermore, we could generate a maintenance list or even a game to enrich already uploaded but uncategorized files.
