Recording, replaying and modifying an Unstructured Information Management Architecture (UIMA) pipeline

摘要

The technique herein substantially improves productivity of Annotator developers by providing methods and systems to develop and test Annotators without having to run a full pipeline every time changes are made to a particular Annotator. To this end, preferably a running pipeline is instrumented to enable automated recording of static configuration and dynamically-generated event data as the pipeline is executed. Based on these data, a reusable data model is generated that captures code and other dependencies in the pipeline (e.g., configuration parameters, intermediary CASes, program flow, annotations, and the like). The data model is then used to facilitate testing of Annotators without using the full pipeline (or even major sub-pipelines therein).

主权项

1. A method of testing elements of a pipeline software system, comprising:
as the pipeline software system executes, receiving information about a state of the pipeline software system; saving, according to a data model, the information as representative of conditions existing within the pipeline software system; and replaying execution of the pipeline software system using the data model and without requiring initialization and re-execution of the pipeline to perform a development action with respect to an element; wherein at least one of the receiving, saving and replaying steps is carried out in software executing in a hardware element.
