Awarded plagiarism algorithm

  • The first place on the 3rd International Competition on Plagiarism Detection during conference CLEF 2011 Labs and Workshops, 19-22 September, Amsterdam, The Netherlands. Our algorithm was best in most evaluation parameters [1] [2].
  • Winner of the European Prize for Innovation in Public Administration 2013 [3].

Powerful, robust and multilingual

We offer a sophisticated text matching algorithm (full match, statistical similarity) with a sophisticated performance scaling mechanism. We support various deployment scenarios, large and small repositories, centralized and distributed solutions. The internal representation is also suitable for deploying language translators and analysis of document originally in different languages.

Are you looking for an inexpensive solution and are it enough if the results are within an hour? Do you need performance without compromise on a really large amount of data? Contact us.

Open, flexible and cost-effective

We support various types of installations. We offer the system primarily as a service (SaaS). Once the technical and safety conditions have been met, we are able to operate the system on customer's facilities as well. In this type of installation, however, the cost of the overtime is also important for the customer. How many documents can be indexed on one server? What are the costs for obtaining and running this server? For long-term cooperation and large installations, these costs are substantial.
