DUCC stands for Distributed UIMA Cluster Computing. DUCC is a cluster
management system providing tooling, management, and scheduling
facilities to automate the scale-out of applications written to the UIMA
framework. Core UIMA provides a generalized framework for applications
that process unstructured information such as human language, but does 
not provide a
scale-out mechanism. UIMA-AS provides a scale-out mechanism to
distribute UIMA pipelines over a cluster of computing resources, but
does not provide job or cluster management of the resources.

DUCC defines a formal job model that closely maps to a standard UIMA
pipeline. Around this job model DUCC provides cluster management
services to automate the scale-out of UIMA pipelines over computing
clusters. It is primarily intended to be used for research and
development activities where multiple users need to efficiently share
cluster resources for a wide variety of computational activities.
Because DUCC is built for UIMA-based analytics from the ground up it
automatically makes available such details as what annotators are
currently initializing as well as the timing breakdown for each
primitive annotator in a pipeline.

The Unstructured Information Management Architecture (UIMA) is a
component framework supporting development, discovery, composition, and
deployment of multi-modal analytics tasked with the analysis of
unstructured information.
