amr-ccg-alignment's Issues

Make JavaScript interface

The javascript interface should:

• handle html coloring based on span classes (l1, l2, ...; s1, s2, ...)
• allow users to click a button to switch between viewing lexical and structural alignments

Better workflow for updating prealignments

A minor annoyance is that currently, to adjust an alignment from preprocessing, I have to delete it and create a new one, which is placed last in the list. Then it takes time to go back and find the next prealignment to review. This could be improved by any of the following:

• A visual indication in the alignment buttons of which are from preprocessing and which I have added
• Keeping alignment buttons, including the newest ones, sorted by word position rather than newness
• An option to update an existing alignment directly, rather than removing an adding a new one

Show-All Button

Consider adding an option to show all alignments for an AMR at the same time. Overlapping alignments could have multiple shading: multi-shades css.

Add dependency tree support

Add dependencies (displayed over sentence) for each amr.

Undo Button

Add a way to remove an alignment.

Show relevant alignment numbers on hover

When hovering on a word or part of the AMR which is part of one or more existing alignments, it would be helpful if the alignment buttons for those alignments would be darkened. That way when I'm browsing the alignments for a sentence, it is easy to select one for a particular word or AMR node/edge.

Errors in Aligner should be more visible

For example, the border of the input box could turn red.

Colored html highlighting for AMR/UD lexical alignments

I should make a tool that reads an AMR/UD alignment file and outputs html with the (lexical) alignments colored.

Add CCG support: demo_v2

Users should be able to align AMR and CCG elements. For CCG visualization, see https://github.com/nschneid/ccg-cxns.

CCG categories with coindexed subparts

E.g. control verbs should coindex the subject NP of the complement with the subject of the matrix verb: something like (S\NP.1)/(S[inf]\NP.1) for "want" and (S[inf]\NP.1)/(S[b]\NP.1) for "to" in "I want to eat cake". Is it possible to obtain this information, perhaps using GraphParser?

If so, then we could tell annotators not to align anything coindexed with part of an outer argument: in the example, the semantic relation corresponding to expected subject of the embedded verb would account for the NP.1 argument, so "want" would not align to any of the semantic args of "eat".

Imperatives and vocatives

Today I suggested there could be type conversion rules to turn S[b]\NP into S[imp] for imperatives and NP into S[voc]/S[dcl] for vocatives. But this would make alignment to the AMR difficult, and in retrospect it violates the spirit of CCG which is to bake as much as possible into the lexicon.

What about lexical rules as follows:

• For every bare verb (including copula "be"), there should be not only an S[b]\NP... type category, but also S[imp]\NP[you]... and subjectless S[imp]...
• For every complete sentence-producing category (this may include all S except S[ng], S[b], and S[adj]), produce a variant that takes a vocative NP on the left or right: e.g. S[dcl]\NP

Thus:

• Be yourself! be : S[imp]/NP (subjectless)
• You be yourself! be : S[imp]\NP[you]/NP
• John, you be yourself! be : S[imp]\NP\NP[you]/NP
• Eat dung, Malfoy! eat : S[imp]/NP/NP
• John, he will not hurt you. will : (S[dcl]\NP\NP)/(S[b]\NP)
• John, are you crying? are : (S[q]\NP/(S[ng]\NP))/NP
• Boy, why are you crying? why : S[wq]\NP/S[q]

This all does feel like a hack, though.

Data Upload

Users should be able to upload AMRs and other data.
Planned support for:

• AMRs
• Sentences
• CCG
• UD

AMR/UD structural alignments

I should make a tool that reads an AMR/UD alignment file and outputs html with the (structural) alignments colored. Extends #1 for alignments between subgraphs.

Alignments Upload/Download

Users should be able to download text file of alignments. Consider supporting uploading partial alignments, for additions/corrections.
