# Match by word overlap

### Description
Finds matches between the `STRING`-columns in the inputs by calculating the [Jaccard Index](https://en.wikipedia.org/wiki/Jaccard_index): count of word intersection divided by count of word union.

### Input
- `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

### 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
- `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
