UIMA
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.
Structure
The UIMA architecture can be thought of in four dimensions:- It specifies component interfaces in an analytics pipeline.
- It describes a set of design patterns.
- 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.
- It suggests development roles allowing tools to be used by users with diverse skills.
Implementations and uses
Apache UIMA, a reference implementation of UIMA, is maintained by the Apache Software Foundation.UIMA is used in a number of software projects:
- IBM Research's Watson uses UIMA for analyzing unstructured data.
- The Clinical Text Analysis and Knowledge Extraction System 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.
