"[Property A] vs. not so" BPs will be assigned keyword "allsorted" (left-BP509)--that is, they sort all relevant examples--unless there exist ambiguous border cases, unclear about whether they fit [Property A] or not.

Left-sorted BPs have the keyword "notso" on the OEBP.

The "not" side conventionally tends to be the right side.

When one property is "positive-seeming" property and its opposite is "negative-seeming", that usually means the negative property wouldn't be recognized without counter-examples (e.g. a collection of "non-triangle shapes" will just be interpreted as "shapes" unless triangles are shown opposite them), while the positive property would be recognized without counter-examples (e.g. a collection of triangles will be seen as such).

BP513 (keyword "left-narrow") is about Bongard Problems whose left side can be recognized without the right side. "Not so" Bongard Problems with a positive-seeming property on the left and a negative-seeming property are thus often "left-narrow" (left-BP513) and not "right-narrow"(BP514).

Note the solution may still be "___ vs. not so" when both sides are positive-seeming: particularly when the left and right side partition the whole example set into two groups (see the "allsorted" keyword left-BP509). Consider, for example, two equivalent definitions of a Bongard Problem: "shape has hole vs. does not" and "shape is not filled vs. is".

If a Bongard Problem's solution is "[Property A] vs. not so", the "not so" side is everything without [Property A] within some suitable context. A Bongard Problem "triangles vs. not so" might only include simple shapes as non-triangles; it need not include images of boats as non-triangles. It is not necessary for all the kitchen sink to be thrown on the "not so" side (but it is in this BP).
