DKPro Statistics - Welcome

A collection of open-licensed statistical tools written in Java

DKPro Statistics is a collection of open-licensed statistical tools written in Java. The software library is divided into the following modules:

  • DKPro Agreement (dkpro-statistics-agreement) is a module for computing multiple inter-rater agreement measures using a shared interface and data model. Based on this model, the software allows for analyzing coding (i.e., assigning categories to fixed items) and unitizing setups (i.e., segmenting the data into codable units). The software has been described in our COLING 2014 demo paper.
  • DKPro Correlation (dkpro-statistics-correlation) is a module for computing correlation and association measures. It is currently under construction.
  • DKPro Significance (dkpro-statistics-significance) is a module for assessing statistical significance. It is currently under construction.

License and Availability

The latest version of DKPro Statistics is available via Maven Central. If you use Maven as your build tool, then you can add DKPro Statistics as a dependency in your pom.xml file:


In addition to that, you can add each of the modules described above separately (e.g., artifactId dkpro-statistics-agreement).

DKPro Statistics is available as open-source software under the Apache License 2.0 (ASL). The software thus comes “as is” without any warranty (see license text for more details).
