LingPipe Licenses

We offer LingPipe under a range of licenses which range from free to perpetual server licenses. Please see our download page for pricing and descriptions.

Third-Party Licenses for Optional Components

Required Libraries

No external libraries are required to compile LingPipe.

Optional Build and Testing Libraries

LingPipe employs the following libraries for build automation and testing. They are not required to compile or to use LingPipe.

• JUnit    [ Common Public License ]
  Junit is a unit-test framework used for testing LingPipe.
• Apache Ant    [ Apache License ]
  Ant is an XML-based build (make) tool.

Optional Demo Libraries

Some of our demos import external libraries. None of them are required to run LingPipe itself. Here's a listing of relevant libraries and licenses.

• NekoHTML    [ CyberNeko License ]
  Parses HTML documents producing SAX events. Depends on the Apache Xerces J libraries (see above).
• Apache Lucene    [ Apache License ]
  Full text indexing and search engine.
• Luke    [ Apache License ]
  Luke provides a GUI visualizer for Lucene indexes and search.
• International Components for Unicode    [ X License ]
  ICU provides a comprehensive package for unicode handling.
• MySQL    [ MySQL Open Source License ]
  We use MySQL for a database demo. Because the MySQL license is basically the Gnu General Public License (GPL) we do not distribute it with LingPipe.
