No matter what your specific needs are, MPCA has the tools to help you get the job done.
In addition to its comprehensive analysis tools, MPCA also includes a variety of utilities for generating reports, file dumping, and more. But that's not all - this latest release of MPCA includes some exciting new features, including linkages to the ALVIS system to create topic models and annotate linguistically tagged content. Cleanups with the linkBags Perl utilities have also been moved out to CPAN.
