U-Compare is an integrated text mining/natural language processing system based on the UIMA Framework, which provides access to a large collection of ready-to-use interoperable natural language processing components, currently the world's largest UIMA component repository. U-Compare allows users to build complex NLP workflows via an easy drag-and-drop interface, and makes visualization and comparison of the outputs of these workflows simple.
