Design and implementation of the UIMA common analysis system

The Common Analysis System (CAS) is the subsystem in the Unstructured Information Management Architecture (UIMA) that handles data exchanges between the various UIMA components, such as analysis engines and unstructured information management applications. CAS supports data modeling via a type system independent of programming language, provides data access through a powerful indexing mechanism, and provides support for creating annotations on text data. In this paper we cover the CAS design philosophy, discuss the major design decisions, and describe some of the implementation details.

PGM/F: A Framework for the Optimization of Data Processing in Business Processes

Workflow languages like BPEL are broadly adopted by industry to integrate the heterogeneous applications and data stores of an enterprise. Leading vendors provide extensions to BPEL that allow for a tight integration of data processing capabilities into the process logic. Business processes exploiting these capabilities show a remarkable potential for optimization. In this demonstration, we present PGM/F, a framework for the optimization of data processing in such business processes.
