NetgraphPlease note that Java Runtime Environment (JRE) from Sun Microsystems must be installed in order to run the Netgraph client. It is not a part of
Netgraph installation programs - it must be installed separately. At least version 1.5 is needed (the client was
compiled in Java 1.5.0_12).
The newest version of JRE for various platforms can be downloaded from http://java.sun.com/javase/downloads/.
Please note that the Netgraph client may not work with other-parties versions of Java Runtime Environment.
The most recent version of Netgraph is 1.95 (client still 1.94), issued on August 7th 2008 (see ChangeLog for changes).
For Linux and MS Windows, installation programs for the client and (optionally) the server are provided:
- Netgraph-1.95-PDT20Sample-Linux-x86-Install - for Linux
- Netgraph-1.95-PDT20Sample-Windows-Setup.exe - for MS Windows
In the installation program, the user can choose parts of the program to install. Either only the Netgraph client is installed (to access the Netgraph
public server), or also Netgraph server along with the Prague Dependency Treebank 2.0 sample data are installed (pcre library is needed to run the Netgraph server - see the system requirements for running the Netgraph server).
For other operating systems, a general java archive of the Netgraph client is provided: netgraph_client_application.jar.
It can be started with the command java -jar netgraph_client_application.jar.
The source code of the Netgraph client
and the source code of the Netgraph server are available as well. See the system requirements for compiling the Netgraph client and server. The PDT 2.0 sample data in FS format are available both on the analytical layer and the tectogrammatical layer.
Icons are available for the client, the server and the manual.
Netgraph is a free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 3 of the License, or (at your option) any later version.
If you have used one of the installation programs, an uninstallation script should also have been installed along with the client or the server.
If you have installed the client or the server manually, it is sufficient to delete the directory you have installed it to. For the server on MS Windows, directory C:\cygwin should be removed too, but only in case that you did not have cygwin installed before separately.
For details, see Netgraph Client User Manual and Netgraph Server User Manual.
The Netgraph server can only work with a treebank in FS Format. For converting the Prague Dependency Treebank 2.0 data to FS Format, a tree editor TrEd is used. The editor can export trees to FS Format and a command-line macro processor btred of the tree editor TrEd is used to automatize the conversion.
