EVALD 4.0 for Beginners – Evaluator of Discourse

EVALD 4.0 for Beginners
=======================

EVALD 4.0 for Beginners is a software that serves for automatic evaluation of Czech texts
written by non-native speakers of Czech – language beginners.

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 4.0 for Beginners:
===============================================================

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-begin/.

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

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:4.0
docker pull ufal/evald.php-server:4.0

See the EVALD 4.0 for Beginners project web pages
(http://ufal.mff.cuni.cz/evald/documentation) for further instructions.
