BoostSRL - v1.1

BoostSRL (Boosting for Statistical Relational Models) is a gradient-boosting based approach to learning different types of SRL models.

As with the standard gradient-boosting approach, our approach turns the model-learning problem to learning a sequence of regression models. The key difference to the standard approaches is that we learn relational regression models (i.e. regression models that operate on relational data). We assume the data to be in predicate-logic format and the output are essentially first-order regression trees where the inner nodes contain conjunctions of logical predicates.

Getting Started

Prerequisites:

• Java (tested with openjdk 1.8.0_144)

Installation:

• Download stable jar file.
• Download stable source with git.
  git clone -b master https://github.com/boost-starai/BoostSRL.git
• Nightly builds with git.
  git clone -b development https://github.com/boost-starai/BoostSRL.git

Basic Usage

BoostSRL assumes that data are contained in files with data structured in predicate-logic format.
