KReator
A Toolbox for Relational Probabilistic Knowledge Representation, Reasoning and Learning

KReator is an integrated development environment (IDE) for relational probabilistic knowledge representation languages. At the moment, KReator supports Bayesian Logic Programs (BLPs), Markov Logic Networks (MLNs), Relational Maximum Entropy (RME), Relational Bayesian Networks (RBN), and Probabilistic Prolog (ProbLog).

KReator is still in development and more features will be added in the near future.

Installation

For universal Jar files:

Just unzip "KReator_vXXX.zip" (on Mac OS X: unpack "KReator_vXXX.dmg") and start KReator by either double-clicking "KReator.jar" directly or using the Shell scripts "StartKReator(Win).bat" (under Windows) or "StartKReator(X)" (under X). In order to use MLN functionalities you have to reference the path to "Alchemy" (license note) in the KReator Settings dialogs. Alchemy builds for Windows, Linux, and Mac OS X are included in the KReator bundle. In order to use the "Export and Open in Spirit" function from within KReator you have to reference "SPIRIT" in the KReator settings dialog. An older version of "SPIRIT" that is distributed under GPL is included in the KReator bundle.

For some information on first steps see README.

Contribute
Researchers and developers of models for statistical relational learning are encouraged to provide a KReator plugin for their specific model type. Please follow the instructions provided in "Plugin Development for KReator". If you want other developers to benefit from your implementation please consider to e-mail your plugin to the KReator team. We will publish your plugin on this page.

Examples
A set of benchmark examples for relational probabilistic models can be found in our model repository.
