The snowball stemmers in
opennlp-tools/src/main/java/opennlp/tools/stemmer/snowball
were developed by Martin Porter and Richard Boulton.
The full snowball package is available from
http://snowball.tartarus.org/

The bundled stopword lists in
opennlp-core/opennlp-runtime/src/main/resources/opennlp/tools/stopword
are derived from Apache Lucene
(https://github.com/apache/lucene/tree/main/lucene/analysis/common/src/resources/org/apache/lucene/analysis),
which in turn distributes them under the BSD license from the Snowball project
(https://snowballstem.org/license.html). The Bulgarian list (bg.txt) is the
Lucene per-language Bulgarian stopwords file originally created by Jacques
Savoy (http://members.unine.ch/jacques.savoy/clef/index.html) and also
distributed under the BSD license. The original upstream license and
attribution headers are preserved verbatim at the top of each bundled file.

This product bundles data files from the Unicode Character Database (UCD)
and the Unicode Security Mechanisms, version 17.0.0, published by Unicode,
Inc. (https://www.unicode.org/Public/).

  * opennlp-core/opennlp-runtime/src/main/resources/opennlp/tools/tokenize/uax29/WordBreakProperty.txt
    is the upstream WordBreakProperty-17.0.0.txt, unmodified except for the
    file name.
  * opennlp-core/opennlp-runtime/src/test/resources/opennlp/tools/tokenize/uax29/WordBreakTest.txt
    is the upstream WordBreakTest-17.0.0.txt, unmodified except for the file
    name.
  * opennlp-core/opennlp-runtime/src/main/resources/opennlp/tools/util/normalizer/confusables.txt
    is the upstream confusables.txt from the Unicode Security Mechanisms
    (UTS #39), unmodified.
  * opennlp-core/opennlp-runtime/src/main/resources/opennlp/tools/util/normalizer/CaseFolding.txt
    is the upstream CaseFolding.txt (version 17.0.0) from the Unicode Character
    Database (UCD), unmodified.
  * opennlp-core/opennlp-runtime/src/main/resources/opennlp/tools/tokenize/uax29/ExtendedPictographic.txt
    is derived from the upstream emoji-data.txt (Emoji Data for UTS #51,
    version 17.0): it keeps only the lines that assign the
    Extended_Pictographic property and is renamed accordingly. It is a
    filtered subset; the upstream file additionally carries the Emoji,
    Emoji_Presentation, Emoji_Modifier, Emoji_Modifier_Base, and
    Emoji_Component properties, which are not retained.

The original Unicode copyright and license header is preserved verbatim at the
top of each bundled file. These files are distributed under the Unicode License
V3, the full text of which is reproduced in the LICENSE file accompanying this
distribution.

The project-authored annotation table
opennlp-core/opennlp-runtime/src/main/resources/opennlp/tools/util/normalizer/emoji-annotations.txt
is licensed under the Apache License 2.0, but its name values (the CLDR short
names) and its entity-type/category derivations are transcribed from the
upstream emoji-test.txt (Emoji Keyboard/Display Test Data for UTS #51,
version 17.0), distributed under the Unicode License V3 reproduced in the
LICENSE file. Its sentiment scores are original project judgments; no
third-party sentiment data set is included.
