rst-converter-service

Docker hub: nlpbox/rst-converter-service

REST API to convert between different Rhetorical Structure Theory file formats. It is built on top of the discoursegraphs library.

Supported Input Formats

CODRA
dis (e.g. used by RST-DT corpus)
DPLP
Heilman/Sagae (2015)
rs3
HILDA (also used by Feng/Hirst 2014)
- Note: We don't use the original HILDA format, but a slightly adapted one based on the internal nltk.Tree representation.
- arne-cl/feng-hirst-rst-parser, nlpbox/feng-hirst-service and nlpbox/hilda-service can produce this format.

original HILDA format

(Contrast[S][N]
  _!Although they did n't like it ,!_
  _!they accepted the offer . <P>!_)

adapted HILDA format

ParseTree('Contrast[S][N]', ["Although they did n't like it ,", 'they accepted the offer .'])

Supported Output Formats

dis
rs3
rstlatex (for embedding RST trees into LaTeX documents)
tree.prettyprint (ASCII-style tree)
svgtree (SVG image of an nltk Tree)
svgtree-base64 (base64 encoded SVG image of an nltk Tree)

Installation

The simplest way to install the rst-converter-service is using Docker:

git clone https://github.com/nlpbox/rst-converter-service.git
cd rst-converter-service/
docker build -t rst-converter-service .

Usage

To run the web service, type:

docker run -p 5000:5000 -ti rst-converter-service

In another terminal, you can now convert RST files. To convert the file car-repair.rs3 from rs3 format to dis format, type:

curl -XPOST localhost:5000/convert/rs3/dis -F [email protected]
(Root
  (span 1 2)
  (Satellite
    (leaf 1)
    (rel2par background)
    (text
      _!I am having my car repaired in Santa Monica (1522 Lincoln Blvd.) this Thursday 19th._!))
  (Nucleus
    (leaf 2)
    (rel2par span)
    (text
      _!Would anyone be able to bring me to ISI from there by 5 pm please?_!)))

For "visualizing" the RST tree, you might try prettyprinted trees:

curl -XPOST localhost:5000/convert/rs3/tree.prettyprint -F [email protected]
                 background
        _____________|______________
       S                            N
       |                            |
I am having my               Would anyone be
car repaired in             able to bring me
 Santa Monica (                to ISI from
 1522 Lincoln                 there by 5 pm
  Blvd.) this                    please?
 Thursday 19th.

To see all supported input and output formats, type

curl localhost:5000/input-formats
["codra", "dis", "dplp", "hilda", "hs2015", "rs3"]

curl localhost:5000/output-formats
["dis", "rs3", "rstlatex", "svgtree", "svgtree-base64", "tree.prettyprint"]
