"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I have already investigated this package but it says: The website or source code does not give an explicit license, it should therefore be considered copyrighted. The authors have stated that research use is acceptable but attribution is required. For commercial use, an explicit license is required

Where do you read that formula?

I'm reading much less restrictive words on their main page:
http://www.dbs.ifi.lmu.de/research/KDD/ELKI/:

With the development and publication of ELKI, we humbly hope to serve the data mining and database research community beneficially. The framework is free for scientific, non-commercial usage. In case of application of ELKI in scientific publications, it should be cited with the most recent publication below (see publications).

It does not look that they are selling this stuff, and unless you are going to have direct profit out of your application, I think it is legal to use even within the
industry.
