Evaluate a recent change

entry = next(repo.recentchanges(tag='new editor changing statement', total=1))
item = repo.get_entity_for_entity_id(entry['title'])
new_rev = get_revision_wrapper(item, entry['revid'])
base_rev = get_revision_wrapper(item, entry['old_revid'])

result = evaluator.evaluate_change(base_rev, new_rev)

Evaluate a sequence of changes

entry = next(repo.recentchanges(tag='new editor changing statement', total=1))
item = repo.get_entity_for_entity_id(entry['title'])
base_id, new_id = span_revisions(item, entry)
new_rev = get_revision_wrapper(item, new_id)
base_rev = get_revision_wrapper(item, base_id)

result = evaluator.evaluate_change(base_rev, new_rev)

Evaluate a revision difference

page = next(repo.randompages(namespaces=0, total=1, redirects=False))
item = repo.get_entity_for_entity_id(page.title())
entry = revision_to_entry(item.latest_revision)
new_rev = get_revision_wrapper(item, entry['revid'])
base_rev = get_revision_wrapper(item, entry['old_revid'])

result = evaluator.evaluate_change(base_rev, new_rev)

Evaluate an entity

entry = next(repo.recentchanges(changetype='new', namespaces=[0], total=1))
item = repo.get_entity_for_entity_id(entry['title'])

result = evaluator.evaluate_entity(item)
