Module providing the webservice interface based on the Jetty embedded webserver and the FreeMarker template engine. Defines a simple format for providing textual annotations and produced output in HTML or JSON. This module has no dependencies to the other SCIE modules (except for the PDF text extractor) or the UIMA framework and thus can be used in any context, where text is annotated by an algorithm and should be presented to an end user.

The newest version!
