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
Please see the README for this information.
3. Migrating from IBM UIMA to Apache UIMA
This section describes how to move from pre-Apache versions of UIMA to the
Apache version (starting with Apache UIMA 2.1).
Note: Before running the migration utility, be sure to back up your files, just
in case you encounter any problems, because the migration tool updates the
files in place in the directories where it finds them.
The migration utility is run by executing the script file
apache-uima/bin/ibmUimaToApacheUima.bat (Windows) or
apache-uima/bin/ibmUimaToApacheUima.sh (UNIX). You must pass one argument: the
directory containing the files that you want to be migrated. Subdirectories
will be processed recursively.
The script scans your files and applies the necessary updates, for example
replacing the com.ibm package names with the new org.apache package names.
The script will only attempt to modify files with the extensions: java, xml,
xmi, wsdd, properties, launch, bat, cmd, sh, ksh, or csh; and files with no
extension. Also, files with size greater than 1,000,000 bytes will be skipped.
(If you want the script to modify files with other extensions, you can edit
the script file and change the -ext argument appropriately.)
If the migration tool reports warnings, there may be a few additional steps to
take. The following two sections explain some simple manual changes that you
might need to make to your code.
3.1. JCas Cover Classes for DocumentAnnotation
If you have run JCasGen it is likely that you have the classes
com.ibm.uima.jcas.tcas.DocumentAnnotation and
com.ibm.uima.jcas.tcas.DocumentAnnotation_Type as part of your code. This
package name is no longer valid, and the migration utility does not move your
files between directories so it is unable to fix this.
If you have not made manual modifications to these classes, the best solution
is usually to just delete these two classes (and their containing package).
There is a default version in the uima-document-annotation.jar file that is
included in Apache UIMA. If you have made custom changes, then you should not
delete the file but instead move it to the correct package
org.apache.uima.jcas.tcas. For more information about JCas and
DocumentAnnotation please see Section 5.5.4,
"Adding Features to DocumentAnnotation" in the UIMA References manual
(docs/html/references/references.html).
3.2. JCas.getDocumentAnnotation
The deprecated method JCas.getDocumentAnnotation has been removed. Its use
must be replaced with JCas.getDocumentAnnotationFs. The method
JCas.getDocumentAnnotationFs() returns type TOP, so your code must cast this to
type DocumentAnnotation. The reasons for this are described in Section
5.5.4, "Adding Features to DocumentAnnotation" in the UIMA References manual
(docs/html/references/references.html).
3.3. Rare Cases Where Additional Manual Migration is Necessary
For most users there should not be any additional migration steps necessary.
However, if the migration tool reported an additional warning or if you are
having trouble getting your code to compile or run after running the migration,
please see Section 1.4.2. "Rare Cases Where Additional Manual Migration is
Necessary," in the Overview and Setup manual
(docs/html/overview_and_setup/overview_and_setup.html).
4. How to Get Involved
The Apache UIMA project really needs and appreciates any contributions,
including documentation help, source code and feedback. If you are interested
in contributing, please visit http://incubator.apache.org/uima/get-involved.html.
5. How to Report Issues
The Apache UIMA project uses JIRA for issue tracking. Please report any
issues you find at http://issues.apache.org/jira/browse/uima.
