| <h2><a id="what.is.uima">1. What is UIMA?</a></h2> |
| |
| <p> |
| 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. |
| </p> |
| <p> |
| 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 |
| <a href="http://www.oasis-open.org">OASIS</a>, |
| a standards organization). We invite and encourage you |
| to participate in both the implementation and |
| specification efforts. |
| </p> |
| <p> |
| 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. |
| </p> |
| |
| <h2><a id="major.changes">Major Changes in this Release</a></h2> |
| <p><ul> |
| <li>Update the Eclipse plugins to work with the latest Eclipse (4.6, Neon) version.</li> |
| <li>A new general purpose CAS serialization/deserialization class CasIOUtils, with support for |
| saving type system and index definition information along with the Feature Structures.</li> |
| <li>Sofa mapping support for flow controllers corrected.</li> |
| <li>Correct an stack overflow error in AnnotationViewer when switching Sofas.</li> |
| <li>Correct 2 JSON serialization issues: mishandling of arrays of FeatureStructures having null entries, |
| and mishandling of namespaces for uninstantiated types found as supertypes.</li> |
| <li>Added a new utility class, CasIOUtils, permitting standard saving and loading of CASs in all the |
| formats (except JSON), together (optionally) with the CAS's type system and index definition. |
| </ul> |
| </p> |
| |
| <h3>API changes</h3> |
| <p> |
| There were no User API changes that affect backward compatibility. |
| </p> |
| |
| <h3>Change in Binary Delta serialization</h3> |
| <p> |
| Versioning information is added to the binary serialization streams in a backward compatible manner. |
| In addition, this release includes a <a href="https://issues.apache.org/jira/browse/UIMA-4743">bug fix</a> |
| that changes the format of Binary Delta serialization slightly, but only for delta serialization, as used by |
| UIMA-AS. UIMA-AS next release will include support for this and |
| automatically select the old or new version when sending a delta CAS back to the client; so this change |
| should be invisible to users. |
