Is it legal to make a software to "learn" from open-source datasets like Freebase or WordNet and use it to build an open-source knowledge-base system?
- Freebase license (CC-BY) - Require credit and indicate if changes were made.
- WordNet license - Require the same license for copies or modifications.
Both Freebase and WordNet are open-source licensed but require some kind of acknowledgment (or credit) for any change made to the dataset. My project will most likely learn from those projects and will represent the data in a very different way.
Do I have any restrictions on the data being generated by "learning"? Do I have to acknowledge those sources?
