All Implemented Interfaces:

org.apache.uima.analysis_component.AnalysisComponent

public class WindowAnnotator
extends org.apache.uima.fit.component.JCasAnnotator_ImplBase

This component adds window annotations of type PARAM_TARGET_ANNOTATION over PARAM_WINDOW_SIZE base annotations. The last window might be shorter than the specified window size. By default, the component generates non-overlapping windows. If the parameter PARAM_OVERLAPS is set to true, overlapping windows will be annotated. This option also ensures that every window is exactly the right amount of sub annotations long.
