claimit.py is a script to mass add Wikidata claims to a lot of items based on pages on Wikipedia
A category or template on Wikipedia gives information about what kind of page it is. For example if it contains a person infobox, it's probably a person. Or as another example: If a page is in a certain taxonomic family category, it's probably in that family. Based on this information you can instruct the bot to add claims.
