discoursegraphs 0.1.0

graph-based processing of multi-level annotated corpora

DiscourseGraphs

This library enables you to process linguistic corpora with multiple levels of annotations by:

1. converting the different annotation formats into separate graphs and

2. merging these graphs into a single multidigraph (based on the common tokenization of the annotation layers)

So far, the following formats can be imported and merged:

• TigerXML (a format for representing tree-like syntax graphs with secondary edges)

• RS3 (a format used by RSTTool to annotate documents with Rhetorical Structure Theory)

• an ad-hoc plain text format for annotating expletives (you’re probably not interested in)

Installation

git clone https://github.com/arne-cl/discoursegraphs.git
cd discoursegraphs
python setup.py install # prepend 'sudo' if needed

Requirements

• lxml

• networkx

If you’d like to visualize your graphs, you will also need:

• graphviz

• pygraphviz
