UIMA, short for Unstructured Information Management Architecture, is an OASIS standard for content analytics, originally developed at IBM. It provides a component software architecture for the development, discovery, composition, and deployment of multi-modal analytics for the analysis of unstructured information and integration with search technologies.


The UIMA architecture can be thought of in four dimensions:
  1. It specifies component interfaces in an analytics pipeline.
  2. It describes a set of Design patterns.
  3. It suggests two data representations: an in-memory representation of annotations for high-performance analytics and an XML representation of annotations for integration with remote web services.
  4. It suggests development roles allowing tools to be used by users with diverse skills.
