Platform license

License Policy:

Please note that if you are going to contribute to the EXCITEMENT Open Platform (EOP) you should accept the license policy:

We reserve the right to redistribute the GPL release with modifications under the terms of another license (either Apache v2.0 or LGPL v3 or any other similar license agreement) at a later time without prior notification and permit from the contributors.

---

The first distribution of the EXCITEMENT Open Platform (EOP) is released under the terms of the General Public License (GPL) version 3.

However, from the license agreements point of view there exist two kind of additional resources (i.e. knowledge resources, parsers, etc.) which are needed for using the EOP as an end user:

• 1. GPL-v3-incompatible (the first table below)
• 2. GPL-v3-compatible (the second table below)

Lib=library, Resource=additional resources (knowledge resources, parsers, tools, etc.)

Table 1: GPL-v3-incompatible ones:

No.	Item	Lib/Resource	License	Usecase/Comments
1	GermaNet	Resource	It's own license	Similar to the English (Princeton) WordNet, provides entailment rules for German
2	TextPro	Resource	It's own license	NLP analysis for English and Italian
3	TreeTagger	Resource (tool)	It's own license (The copyright owner, Mr. Helmut Schmid, has permitted the EXCITEMENT project to redistribute the binaries with the EOP.)	German Processing
4	JWKTL	lib	http://www.ukp.tu-darmstadt.de/software/jwktl “t the moment, JWKTL is not GPL-compatible, as it is not available as open-source software. However, we plan to release the software soon (possibly in July/August?). So far, we planned to use the Apache License, which would (as far as I know) allow using JWKTL in your GPL software. Please also study the license of the Berkeley DB, which is being used by JWKTL and might imply transitive conditions. Should be no problem though, but still needs consideration” (Christian Meyer)	-
5	Lingpipe	lib	http://alias-i.com/lingpipe/web/licensing.html “It is not considered to be GPL-v3 compatible but we will very likely adopt the AGPL in the near future. If there is a good reason to move more quickly let me know. I expect within the next 60 days.” (Breck Baldwin)	-
6	JUnit	lib	Common Public License	-
7	jni-svmlight	lib	http://morphix-nlp.berlios.de/manual/node48.html “the code is not GPL. But it is free for research and teaching” (Thorsten Yoachim)"	-

It’s licensed under Creative Commons CC-BY, which to my understanding only requires users to grant credit where credit is due; it allows derivative works and commercial use at no charge. I think this fits with GPL, but, again, I’m not a lawyer. I will certainly not complain if you use JWI in your project, whatever it is, as long as you credit me for JWI.” (Mark Finlayson)	-
33	Biu-normalizer	lib	Free to use, no guarantee (code cleanup and bug fixes are required)	-

This license is based on the terms of the Expat and modified BSD licenses. It is a lax, permissive non-copyleft free software license, compatible with the GNU GPL. On the other hand, many of the libraries used by MorphAdorner have their own licenses as noted on that page as well: http://morphadorner.northwestern.edu/morphadorner/licenses/#thirdpartylicenses	-
