Match by Obj & date-range

Description

Finds matches using the provided object pairs.

The match is performed on:

• the object on the right columns of the inputs

• the date ranges extracted from the objects in the left column of the inputs.

For each match, the objects on the left columns are returned.

Input

• A [OBJ,OBJ]: a list of candidates in the first column, and object to match on in the second column

• B [OBJ,OBJ]: a list of candidates in the first column, and object to match on in the second column

Output

• RESULT [OBJ,OBJ]: the matched objects from A and B

• NOTA [OBJ]: the objects from A that did not match with an item from B

• NOTB [OBJ]: the objects from B that did not match with an item from A

Parameters

• Comparison: Comparison function to use (overlaps, contains)

• Range length means data uncertainty: If true, range lengths are interpreted as the level of uncertainty over otherwise point data. This means that fully overlapping longer ranges get lower scores than fully overlapping shorter ranges.

• Exclude self-matches: whether to emit the match if the objects in A and B are the same. Mostly useful when A and B come from the same source
