References from consequence tag "C" to another tag (in same sentence)

[arildm]

In this example, the C relates to the S-CON.

We cannot use numbers, like in anon, because referencing an edge is not enough. Reference needs to be to a specific label on an edge. (If att in the example were mispelled, there would also be an O tag, and we wouldn't know if C relates to S-CON or O.)

Related problem: "secondary edges", i.e. edges between edges.

(Using "labeling" to refer to a specific label on a specific edge.)

Referencing a specific labeling directly is difficult. Edges ids are "volatile" (they often change) so a reference like e-s23-t23/S-CON would have to be updated a lot, and it would be easy to fall behind.

Could we add indices to labels? A labeling would consist of a label and possibly an index, something like labels: ['S-CON:1', 'O'] and labels: ['C:1']. We would need a UI widget for adding and removing indices from labelings.

Should it be possible to add more than one index to a single labeling? labels: ['C:1:2']

Indices should probably be essay-wide, not sentence-wide. Otherwise, if one later decides to re-segment two sentences to one, indices might clash. Also better for searching in the future.

Lisa:

Tror att dessa referenser bör kunna göras även till element utanför meningen med C-markeringen. Det är till exempel tänkbart att man ändrar ett ord från singular till plural i en mening, och att det leder till att man behöver göra en konsekvensändring av en anafor i efterföljande mening.

Discussed with Elena.

• References should be possible on any label, not just C.
• Unclear whether it should be possible to reference 1) a labeling 2) an edge 3) a source token 4) a target token 4) some combination of these
