UIMA (/juˈiːmə/yoo-EE-mə),^[1] short forUnstructured Information Management Architecture, is anOASIS standard^[2] forcontent analytics, originally developed atIBM. It provides acomponent software architecture for the development, discovery, composition, and deployment ofmulti-modal analytics for the analysis ofunstructured information and integration withsearch technologies.

The UIMA architecture can be thought of in four dimensions:

1. It specifies component interfaces in an analyticspipeline.
2. It describes a set ofdesign patterns.
3. It suggests two data representations: an in-memory representation of annotations for high-performance analytics and anXML representation of annotations for integration with remote web services.
4. It suggests development roles allowing tools to be used by users with diverse skills.

UIMA is used in a number of software projects:

• IBM Research'sWatson uses UIMA for analyzingunstructured data.^[4]
• The Clinical Text Analysis and Knowledge Extraction System (Apache cTAKES) is a UIMA-based system for information extraction from medical records.
• DKPro Core is a collection of reusable UIMA components for general-purpose natural language processing.
