Left-sorted Bongard Problems have the keyword "neither" on the OEBP.
This keyword is for Bongard Problems for which some obviously relevant case, in the same class as the shown examples, clearly would not fit in with either of the two sides.
An example falling in the threshold between a less-than/greater-than comparison (keyword spectrum) is a special case; it is easy to view such an example as belonging on both sides (keyword both) as well as neither side.
NOTE: It might be nice to have a separate keyword for tracking these special-case spectrum-based ambiguities (because they don't quite suit the keywords "both" or "neither"). - Aaron David Fairbanks, Apr 16 2022 |

See also both.
The keywords "neither" and allsorted are mutually exclusive.
Usually, Bongard Problems with a case that fits neither side in a clear-cut way are precise.

Left-sorted Bongard Problems are tagged with the keyword "preciseworld" on the OEBP.
The keyword "preciseworld" basically means: if a new Bongard Problem were created to sort whether or not examples fit in the pool of examples in the original Bongard Problem, it would be tagged precise.
For a Bongard Problem fitting left, the intended class of examples sorted by the Bongard Problem is clear-cut.
For a Bongard Problem fitting right, there isn't any obvious boundary to take as delimiting the pool of potential examples. There is an imprecise fading of relevancy rather than a natural cutoff point.
Sometimes there are specific notable cases of potential examples for which there is ambiguity about whether they belong.
For example, the empty square (zero dots) has been left out of BP989. This is perhaps the only obvious example that is ambiguous as to whether it should be considered as belonging to the pool of examples shown in the Bongard Problem (or any similar dot-counting Bongard Problem).
(There would be no ambiguity if it were actually included in the Bongard Problem.)
(Whether or not zero seems like an obvious example also has a cultural component (see culture); someone who is not accustomed think of zero as a number might not see this as ambiguous at all.)
Larger pools of examples make the absence of notable border cases like this more conspicuous and intentional-seeming. (See also discussion at left-narrow.) But expanding the pool of examples cannot resolve certain border cases: if the rule of the Bongard Problem by nature leaves unsorted a potential example that is a border case for even fitting in with the rest of the examples, its absence doesn't communicate anything; whether it belongs with the pool of examples remains ambiguous.
It is tempting to make another another "allsortedworld" analogous to allsorted. But the pool of relevant examples fitting in a Bongard Problem is like a Bongard Problem with only one side: a collection satisfying some rule. Would there be any difference between precise and allsorted for a Bongard Problem with only one side? |

EXAMPLE
|
Bongard Problems featuring generic shapes ( https://oebp.org/search.php?q=world:fill_shape ) have not usually been labelled "preciseworld". (What counts as a "shape"? Can the shapes be fractally complicated, for example? What exactly are the criteria?) Nonetheless, these Bongard Problems are frequently precise. |
