| <dt>Where can I download the models used in OpenNLP?</dt> |
| <dd>They are hosted <a href="http://opennlp.sourceforge.net/models-1.5/">at SourceForge</a>.</dd> |
| |
| <dt></dt> |

| |
| <dt>How to train a Named Entity Recognition (NER) model?</dt> |
| <dd>To train the name finder model you need training data that contains the entities you would |
| like to detect. |
| Have a look at our manual, in special the sections under the |
| <a href="/docs/2.1.1/manual/opennlp.html#tools.namefind.training">Name Finder Training API</a>. |
| At the beginning of that section you can see how the data has to be marked up. Please note you that you need many sentences to successfully train the name finder.</dd> |
| |
| <dt>How can I speed up my MaxEnt training time</dt> |
| <dd>Try tweaking the value of <a href="/docs/2.1.1/apidocs/opennlp-tools/opennlp/tools/util/TrainingParameters.html#THREADS_PARAM">TrainingParameters.THREADS_PARAM</a>.</dd> |
| |
| <dt>Will my models trained with a previous version of OpenNLP still work with a newer version?</dt> |
| <dd>You should expect it to work. The corpora used is normally the same. However, the behavior may |
| change when we fix bugs or add new features. The test results in the |
| <a href="https://cwiki.apache.org/confluence/display/OPENNLP/Test+Plans">project Wiki</a> may contain useful |
| information about model compatibility.</dd> |
| |
| <dt><strong>Is there a commercial license for OpenNLP?</strong></dt> |
| <dd>OpenNLP is licensed under the business-friendly Apache software license, |
| version 2.0. You can read the license |
| <a href="http://www.apache.org/licenses/LICENSE-2.0">here</a> |
| or <a href="https://en.wikipedia.org/wiki/Apache_License">its Wikipedia page</a> |
| for more information.</dd> |
| |
| <dt><strong>How can I start contributing to this project?</strong></dt> |
| <dd>Have a look at our <a href="/get-involved.html">Getting Involved</a> page. |
| We have a list of issues needing help there, as well as instructions to get started |
| contributing to OpenNLP. You may also consider making |
| <a href="https://www.apache.org/foundation/contributing.html">a donation to the Apache Software Foundation</a>.</dd> |
