| CoNLL 2019 Shared Task: Meaning Representation Parsing --- Sample Graphs | |
| Version 0.9; April 9, 2019 | |
| Overview | |
| ======== | |
| This directory contains a collection of 89 sample graphs in the five framworks | |
| represented in the task: AMR, DM, EDS, PSD, and UCCA. The sentences are drawn | |
| from Section 00 of (the Penn Treebank selection from) the venerable Wall Street | |
| Journal (WSJ) Corpus. We only include sentences for which all five graph banks | |
| provide annotations. | |
| The purpose of this sample data is twofold: (a) exemplify the uniform graph | |
| representation format (serialized in JSON) adopted for the task and (b) enable | |
| in-depth linguistic comparison across frameworks. | |
| For general information on the file format, please see: | |

| Contents | |
| ======== | |
| The main contents in this release are the JSON files: | |
| $ ls -l */*.mrp | |
| -rw-r--r--. 1 oe oe 145935 Apr 8 00:11 amr/wsj.mrp | |
| -rw-r--r--. 1 oe oe 290495 Apr 8 00:12 dm/wsj.mrp | |
| -rw-r--r--. 1 oe oe 334885 Apr 8 00:13 eds/wsj.mrp | |
| -rw-r--r--. 1 oe oe 225669 Apr 8 00:14 psd/wsj.mrp | |
| -rw-r--r--. 1 oe oe 254101 Apr 9 16:07 ucca/wsj.mrp | |
| Each file contains the 89 graphs in the intersection of all frameworks (87 in | |
| the case for UCCA, for the time being). These graph serializations are in what | |
| is called the JSON Lines format, effectively a stream of JSON objects with line | |
| breaks as the separator character between objects. | |
| To ease human inspection of these graphs, this package also provides graphical | |
| renderings of all graphs, as separate files (one per sentence) in the ‘dot/’ | |
| and ‘pdf/’ sub-directories for each framework. These visualizations have been | |
| created using the MRP graph toolkit, which will be released by mid-May 2019. | |
| Known Limitations | |
| ================= | |
| None, for the time being. | |
