SemanText is a semantic network application
which uses topic maps to represent its knowledge base.
SemanText is also capable of extracting topic map
information from XML sources and of using rules-based
inference to enrich a topic map.
A collection of Perl modules for parsing and
manipulating topic map data. Topic maps can be loaded
from an XML based resource (local or remote via an URL)
as prescribed by the XTM standard. There is also a way
to tie a map to any persistent medium. The latter is
especially interesting when running this module along
with a (web) server.
