Handling of coordination+ellipsis

[nikitakit]

The following sentence appears to be a case of clause coordination with an elided verb in the latter two clauses, but the analysis doesn't seem to match with what I can find in the UD guidelines. Is this possibly an annotation error, or am I not understanding things right? (Disclaimer: I have no knowledge of Finnish)

After looking at this some more, it looks like the annotation is consistent in annotating coordination by connecting pairs of words that are "parallel" to each other.

It is still my impression, though, that the UD guidelines and some of the other Finnish treebanks follow a different convention.

At least the following sentences in the training data appear to be affected by this:

• xezs0-6140
• r7bh8-8531
• xox7g-9207
• v125q-11046
• ct5yn-11059
• wvlzx-11083.2
• tpx7s-11098
• fzvdh-11101
• xz0c3-15094.1
• z46wt-15347
• yujti-17090
• tyszx-6712 (maybe)

And at least the following sentences in the test set:

• c1ro6-13800
• saw28-14137
