cTAKES GUI
to build pipelines from cTAKES components and to run pipelines.
- select cTAKES components to include
- view descriptions of the components, and inputs, outputs, parameters, dependencies
- implemented using the new Pipe Bits
Dictionary Builder GUI
to build a custom dictionary from a local UMLS installation.
Temporal Module
multiple new annotators to discover meaningful events, temporal expressions, and their relations from clinical text and place them on a timeline.
Example Clinical Documents with Manual Annotations
hand-annotated clinical narratives (mock ups). The narratives were annotated using the Anafora annotation tool.
Sentence Detector Alternative
if the default sentence detector is not working well for you, you could try the new character-based sentence detector
Coreference Annotator Alternative
a new, second coreference annotator is now included
Pipe Bits
pipe bits are used to describe cTAKES modules for programs that help users create pipelines - see cTAKES GUI.
- document descriptions of components, and inputs, outputs, parameters, dependencies
- implemented as Java annotations
- simplifies pipeline builders
- indicates whether a component is a Collection Reader, Annotator, or a Cas Consumer (Writer)
Changes
if you've written code that directly uses classes within cTAKES, you could be affected by the following:
- Three older, lesser-used assertion-related classes were removed from cTAKES to remove a dependency on jars that are not in maven central:
- AssertionAnalysisEngine
- AssertionAnalysisEngineFit
- ConceptConverterAnalysisEngine
- Class IdentifiedAnnotationUtil was renamed to OntologyConceptUtil
