pepperModules-GraphAnnoModules

This project provides an exporter to to support a JSON based format which can be read by the GraphAnno Tool for the linguistic converter framework Pepper (see https://u.hu-berlin.de/saltnpepper). Attention this plugin was developed to test a single corpus comming from a simple text (the only module involved in that workflow next to the GraphExporter was the TextImporter). That means, this plugin is not well tested.

Pepper is a pluggable framework to convert a variety of linguistic formats (like TigerXML, the EXMARaLDA format, PAULA etc.) into each other. Furthermore Pepper uses Salt (see https://github.com/korpling/salt), the graph-based meta model for linguistic data, which acts as an intermediate model to reduce the number of mappings to be implemented. That means converting data from a format A to format B consists of two steps. First the data is mapped from format A to Salt and second from Salt to format B. This detour reduces the number of Pepper modules from n²-n (in the case of a direct mapping) to 2n to handle a number of n formats.

In Pepper there are three different types of modules:

• importers (to map a format A to a Salt model)
• manipulators (to map a Salt model to a Salt model, e.g. to add additional annotations, to rename things to merge data etc.)
• exporters (to map a Salt model to a format B).

For a simple Pepper workflow you need at least one importer and one exporter.

Requirements

Since the here provided module is a plugin for Pepper, you need an instance of the Pepper framework. If you do not already have a running Pepper instance, click on the link below and download the latest stable version (not a SNAPSHOT):

Note: Pepper is a Java based program, therefore you need to have at least Java 7 (JRE or JDK) on your system. You can download Java from https://www.oracle.com/java/index.html or http://openjdk.java.net/ .

Install module

If this Pepper module is not yet contained in your Pepper distribution, you can easily install it. Just open a command line and enter one of the following program calls:

Windows

pepperStart.bat 

Linux/Unix

bash pepperStart.sh 

Then type in command is and the path from where to install the module:

pepper> update de.hu_berlin.german.korpling.saltnpepper::pepperModules-pepperModules-GraphAnnoModules::https://korpling.german.hu-berlin.de/maven2/

Usage

To use this module in your Pepper workflow, put the following lines into the workflow description file. Note the fixed order of xml elements in the workflow description file: <importer/>, <manipulator/>, <exporter/>. The GraphAnnoExporter is an importer module, which can be addressed by one of the following alternatives. A detailed description of the Pepper workflow can be found on the Pepper project site.

a) Identify the module by name

<exporter name="GraphAnnoExporter" path="PATH_TO_CORPUS"/>

b) Identify the module by formats

<exporter formatName="json" formatVersion="1.0" path="PATH_TO_CORPUS"/>

c) Use properties

<exporter name="GraphAnnoExporter" path="PATH_TO_CORPUS">
  <property key="PROPERTY_NAME">PROPERTY_VALUE</property>
</exporter>
