Match by Word Overlap

Finds matches between the STRING-columns in the inputs by calculating the Jaccard Index: count of word intersection divided by count of word union.

• A [OBJ,STRING]: a list of candidates, in which the STRING-column will be used for comparison and the OBJ-column will be the result
• B [OBJ,STRING]: a list of candidates, in which the STRING-column will be used for comparison and the OBJ-column will be the result

• 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

• Case-sensitive: if set to false, upper/lower case is ignored
• Consider term frequency: whether the number of occurrences of a term in a text should influence the score
• 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
