Apache UIMA came out of the efforts from Ferrucci and others from TJ Watson Research Lab. "Watson's" secret sauce was the filtering and ranking, you get multiple results from the models, which ones do you pick? There was significant engineering effort put into reducing the latency of getting answers out of the pipeline as well, you had to optimize given the constraints of latency, accuracy and confidence from the pipeline.
