Press Release of the Univ. of Konstanz: HTML | PDF

Human Bios is a Swiss company specializing in technologies that prevent tampering with physical objects. Specifically, the company has developed the concept of dynamic security, which makes use of time-dependent, unpredictable changes of physical security elements, such as specialized coatings, to develop authentication and authorization concepts. In the future, Human Bios seeks to leverage the potential of the blockchain to develop novel security concepts. Given the expertise of our group in the research area of blockchain applications, the company chose us as a partner to further advance their research efforts.

Norman Meuschke represents ACM SIGIR at the
50th Turing Award Celebration

January 18, 2017The Special Interest Group on Information Retrieval (SIGIR) within the Association for Computing Machinery (ACM) has selected our group member Norman Meuschke as one of ten students to represent SIGIR at the 50th ACM Turing Award Celebration in San Francisco, on June 23 - 24, 2017.


The ACM Turing Award, established in 1966 and often referred to as the “Nobel Prize of computing” - is the most prestigious technical award in the computer science community. ACM will celebrate the 50th anniversary of the award and the landmark contributions in computing that the award represents with a two-day conference in the heart of San Francisco. In addition to the award ceremony, the conference program includes a series of panels with Turing laureates and recipients of other distinguished information technology research awards.

Our research on

July 13, 2016 — The German magazine Spektrum der Wissenschaft covered our research on blockchain technologies (for instance used in the crypto currency Bitcoin).

Improved math rendering in Wikipedia

May 31, 2016 — Wikipedia is using a new approach for rendering mathematical formulae - as of May 31st. This approach was developed by our group member Moritz Schubotz.

Bitmap images representing formulae, were replaced with a combination of MathML (the web standard for mathematics on the web), in addition to a  fallback mechanism for browsers that do not support this web standard.

This approach makes formulae machine readable and accessible to users with limited vision, while also looking crisper on high resolution displays and in print.

New release of Docear

October 22, 2013 — Version 1.0 is out now. We’ve added several new features and made many improvements over the past few months. See for yourself:

Docear video available at:

New user manual   |   Download

What is Docear?

Docear is an open source software for literature management that is tailored to the needs of students, researchers, and academics. Docear bundles multiple tools for academic literature and knowledge management into a single interface. The software combines a mind-mapping tool with a recommender system for academic literature and a reference manager.

The mind maps allow users to organize their ideas and to import the annotations they made while reading PDFs, e.g., comments, highlights or bookmarks. Docear works with standard PDF annotations, thus can be used with different PDF viewers.

Docear helps researchers with:

  • Organizing thoughts and annotations (mind map)
  • Creating new documents (exporting outlines from mind map)
  • Finding new academic literature (recommender system)

Docear is free and open source and offers many additional features. Please visit for details.



CitePlag got a makeover

October 18, 2013 — CitePlag is the first prototype of a citation-based Plagiarism Detection (CbPD) System. The prototype was recently demonstrated at the SIGIR conference 2013.

What makes CitePlag novel?

In contrast to existing text-based approaches to plagiarism detection, CitePlag does not solely analyze literal text matches to determine document suspiciousness – but rather, CitePlag makes use of the unique citation placement in the full-text of documents to determine similarity and detect potential plagiarism.

In examining citation placement, position, and order, CitePlag forms a text-independent / and even language-barrier transcending “fingerprint” of the semantic content of documents, which can then be used to detect potential unoriginality and plagiarism.

CitePlag has come a long way from its humble beginnings in 2010, when we proposed the first citation-based approach to detect semantic similarity between documents for use in plagiarism detection. A year later, we developed the algorithms, and today we have a working prototype available for public use.

CitePlag now has a new user interface with improved functionality.

You can:

  1. upload your own files  (PDF/ text documents)
  2. examine recent plagiarism findings and examples of retracted plagiarism cases
  3. compare any two publications from the Open Access subset of PubMed’s database  (200,000+ medical publications)

Test the CitePlag prototype for yourself at its new home on the web:

If you’re curious about the project, see our related publications or the doctoral thesis of Bela Gipp, which narrows in on all aspects of Citation-based Plagiarism Detection.
