EVALD 3.0 – Evaluator of Discourse

=========
EVALD 3.0
=========

EVALD 3.0 is a software for automatic evaluation of surface coherence (cohesion) in Czech texts
written by native speakers of Czech. 
It is an update of the previous versions, EVALD 1.0 and EVALD 2.0.

The evaluation part (the server) is implemented in Treex (http://ufal.cz/treex), a highly modular
NLP framework written in the Perl programming language, and uses the Weka toolkit
(http://www.cs.waikato.ac.nz/ml/weka/) for the final prediction of a coherence mark.
It can be used directly from a command line or as a backend server for a client.
The client part is implemented as a web server, accessible with a web browser.

=================================================
There are three possible ways of using EVALD 3.0:
=================================================

1. interactively as a web demo and RESTful web service hosted at the LINDAT/CLARIN server,
2. interactively but locally, with both the server and the client running on the same machine (or two machines
   in the same network),
3. in a batch mode run on the local machine.

=================================================

Ad 1) No installation is needed in this case; in a web browser (such as Firefox or Chrome),
go to https://lindat.mff.cuni.cz/services/evald/.

=================================================

Ad 2) Both the backend server and the client components are distributed via the Docker software
(https://www.docker.com/), which needs to be installed first. Docker greatly simplifies
the installation process of the two components and allows them to be run on Linux-based
operating systems, Windows 10, as well as Mac OS X.

To download both the server and the client, run the following commands:

docker pull ufal/evald.treex-server:3.0
docker pull ufal/evald.php-server:3.0

See the EVALD 3.0 project web pages (http://ufal.mff.cuni.cz/evald/documentation) for further
instructions.
