The Contribution Quality filters are based on the ORES damaging test. By providing predictions about which edits are likely to "have problems" and which are likely to be "good," they enable reviewers better target their work. Based on the explorations in T146333, we've settled on four filters (for final names and description texts, see T149385).
In creating these four levels, we strove to balance users' desires for accuracy versus breadth of coverage. Below see the ORES Damaging score range for each filter (in square brackets, subject to discussion--see below); descriptive language for each filter is in quotes:
- **Very likely good** [55% __and below__] "Highly accurate at finding almost all problem-free edits."
- **May Have problems** [16% __and above__] "Finds most flawed or damaging edits but with lower accuracy."
- **Likely Have Problems** [75% __and above__] "Finds half of flawed or damaging edits with medium accuracy."
- **Very Likely Have Problems** [95% __and above__] "Highly accurate at finding the most obvious 30% of flawed or damaging edits."
**Notes about the Quality filters**
- These filter ranges will, at least initially, be identical with those built into the ReviewStream feed.
- Because the "Problem" filters overlap, they are subject to the behavior stated in T149391, under 'No-Effect Display States", and T149452, under "'Excluded Display States."
**About the functionality of all new RC page filters generally**
- Like all filters in the enhanced RC page filter UI, these filters conform to a set of rules that are, in some ways, very different from the existing RC page filters. The existing filters are designed primarily to EXCLUDE selected properties. The new filters are intended to INCLUDE those properties; logically, the filters within each new group constitute a set of OR filters (each group of ORs being connected to other groups by ANDS). So, the filters in this group follow these rules:
- To INCLUDE property A, users check the box for property A.
- To EXCLUDE property A, the user must uncheck A and check it's complements, properties B, C and D.
- If NONE of A, B, C or Dare checked, then ALL are included.
- If ALL of A, B, C and D are checked, then the result is the same: ALL are included.
