1. What is UIMA?

Unstructured Information Management applications are software systems that analyze large volumes of unstructured information in order to discover knowledge that is relevant to an end user. UIMA is a framework and SDK for developing such applications. An example UIM application might ingest plain text and identify entities, such as persons, places, organizations; or relations, such as works-for or located-at. UIMA enables such an application to be decomposed into components, for example "language identification" -> "language specific segmentation" -> "sentence boundary detection" -> "entity detection (person/place names etc.)". Each component must implement interfaces defined by the framework and must provide self-describing metadata via XML descriptor files. The framework manages these components and the data flow between them. Components are written in Java or C++; the data that flows between components is designed for efficient mapping between these languages. UIMA additionally provides capabilities to wrap components as network services, and can scale to very large volumes by replicating processing pipelines over a cluster of networked nodes.

Apache UIMA is an Apache-licensed open source implementation of the UIMA specification (that specification is, in turn, being developed concurrently by a technical committee within OASIS , a standards organization). We invite and encourage you to participate in both the implementation and specification efforts.

UIMA is a component framework for analysing unstructured content such as text, audio and video. It comprises an SDK and tooling for composing and running analytic components written in Java and C++, with some support for Perl, Python and TCL.

2. Major Changes in this Release

This section describes what has changed between version 2.2.2 and version 2.3.0 of UIMA C++.

2.1. Enhancements to C++ service wrapper for UIMA AS

• Separate JMS listener for getMeta requests (same as Java services)
• Automatic reconnect to AMQ broker when broker becomes available again
• Fixed bug with termination when deployed from Java as separate process
• Fixed bug with timing statistics reported to JMX when deployed from Java
• Fixed bug with capability specs returned in getMeta reply
• Fixed bug where elementType was not returned in getMeta
• Fixed bug with out-of-typesystem data sending back invalid XML strings
• Fixed bug where feature reference updates were not sent back

2.2. Enchancements to runAECpp application

• Added -lenient option to ignore out-of-typesystem data for Xmi format input files
• Options added to support multi-threaded stress testing of a C++ annotator
• Output CAS files written in XMI format

2.3. Parameter overrides supported for C++ annotators colocated with JVM

• Parameter overrides now supported for C++ annotators that are included in Java aggregates as colocated components, or from Java application instantiating C++ annotators directly

2.4. UIMA AS C++ deployment descriptor sample added

• UIMA C++ services can be deployed from Java as separate processes. A sample descriptor is included along with associated documentation.

3. How to Get Involved
