List of items for which a good MRS could not be reached

[suarezallegue]

In some cases, treebanking results in a correct-looking tree, but the MRS has some sort of problem: the top handle may be unexpected (e. g., tbdb12 ID8649) some constituents are isolated from the rest of the sentence; others have more arguments than expected; others have handles which lead to dead ends in the MRS etc. This may happen with sentences for which the SRG has reached a gold tree and for those which we trebank manually.

Some examples of such items from tbdb12 are the following: ID8604, ID8649, ID9020, ID9246.
