Currently, if wbgetsuggestions is used on an item which have more than 15 different statements, it will not give any property suggestions. For instance, https://www.wikidata.org/w/api.php?action=wbsgetsuggestions&entity=Q42
I want to tweak wbgestsuggestions to give recommended properties even if they have existed in the item, so that I know which properties are most relevant to that item.
The information about relevant properties allows me to develop a feature for revscoring (https://www.mediawiki.org/wiki/ORES) which signals item completeness.
For developing the feature, we'll use a simple weighted sum based on the probability reported via the wbs_propertypairs table to get signal for completeness. Items with all high probability statements complete should be more likely to *be* complete than items that lack high probability statements.
Concerning to the result limit in the API, we plan to do "continuation" to workaround the limit that is imposed by the API.
