Building MaltParser

MaltParser is distributed both in binary form and with all source code and documentation. If you only want to use MaltParser as a parser you only need to install the distribution (follow the installation guidelines above), but if you need to build the system you should follow these guidelines. To be able to build MaltParser you need Java SE Development Kit (JDK) 6 or later version of JDK and Apache Ant 1.7.0. If you don't have these tools please download and install them by following the instructions on their web sites.

To build the MaltParser distribution:

prompt> cd <path to maltparser-1.9.2 directory>
prompt> ant dist

<path to maltparser-1.9.2 directory> should be replaced by the actual path to the directory where malt-1.9.2 is installed.
