Subject [Incubator Wiki] Update of "OpenNLPProposal" by joern

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Incubator Wiki" for change notification.

The "OpenNLPProposal" page has been changed by joern.


New page:
= OpenNLP Proposal =
The following is a proposal for a new top-level project within the ASF.

== Abstract ==
OpenNLP is a Java machine learning toolkit for natural language processing (NLP).

== Proposal ==

OpenNLP is a machine learning based toolkit for the processing of natural language text. 
It supports the most common NLP tasks, such as tokenization, sentence segmentation, part-of-speech
tagging, named entity extraction, chunking, parsing, and coreference resolution.  These tasks
are usually required to build more advanced text processing services.

The goal of the OpenNLP project will be to create a mature toolkit for the abovementioned
tasks.  An additional goal is to provide a large number of pre-built models for a variety
of languages, as well as the annotated text resources that those models are derived from.

== Background ==

== Rationale ==

== Initial Goals ==

The initial goals of the proposed project are:
 * Bring the scattered community together and make the development process transparent for
 * Write user documentation about all major components
 * Automated build including train and evaluate regression tests
 * Create a new website

== Current Status ==

=== Meritocracy ===

Some of the initial committers are familiar with Apache's idea of meritocracy, others aren't.
 We will get everybody on the same level as part of the incubation process.

=== Community ===

OpenNLP already has a considerable user base, both in industry and academia.  
Core Developers

=== Alignment ===

OpenNLP has tie-ins with several existing Apache projects.  We have been distributing wrappers
for UIMA for some time now (two UIMA committers also contribute to OpenNLP).  We expect this
collaboration to strengthen further after our move to Apache.

Another obvious connection exists to some of the projects under the Lucene umbrella.  On the
one hand, projects like Solr may benefit from the OpenNLP analysis capabilities to create
specialized search for particular domains.  On the other, OpenNLP may benefit from the machine
learning code that is being developed in Mahout, and maybe get some people from that community
to lend a hand.

== Known Risks ==

=== Orphaned products ===

The project has been around for quite a number of years already, it has a well-established
user community and a diverse set of committers.  
Inexperience with Open Source

=== Homogenous Developers ===

The current group of developers is very diverse, no two developers work for the same organization.

=== Reliance on Salaried Developers ===

Most of the developers are not paid to work on OpenNLP, so there is little reliance on salaried
Relationships with Other Apache Products

=== A Excessive Fascination with the Apache Brand ===

== Documentation ==


== Initial Source ==

The source code is maintained in two CVS repositories on SourceForge.

OpenNLP Maxent:

OpenNLP Tools and OpenNLP UIMA:

== Source and Intellectual Property Submission Plan ==

The OpenNLP source code is already open source under the AL 2.0.

== External Dependencies ==
||JWNL||||BSD||||Java Wordnet Library||
||JUnit||||CPL||||Unit Testing Framework||
||UIMA||||AL 2.0||||Unstructured Information Management Architecture||

== Cryptography ==

OpenNLP neither provides nor uses any cryptography.

== Required Resources ==

=== Mailing lists ===

 * opennlp-dev
 * opennlp-private
 * opennlp-user
 * opennlp-commits

=== Subversion Directory ===

=== Issue Tracking ===
