    Logical Markov Random Fields.

LoMRF is an open-source implementation of Markov Logic Networks (MLNs) written in Scala programming language.

1. Parallel grounding algorithm based on Akka Actors library.
2. Marginal (MC-SAT) and MAP (MaxWalkSAT and LP-relaxed Integer Linear Programming) inference (lomrf infer).
3. Batch and on-line Weight Learning (Max-Margin, AdaGrad and CDA) (lomrf wlearn).
4. On-line Structure Learning (OSL and OSLa) (lomrf slearn).
5. MLN knowledge base compilation (lomrf compile):

• Predicate completion.
• Clausal form transformation.
• Replacement of functions with utility predicates and vice versa.
• Reads and produces Alchemy compatible MLN files.

6. Can export ground MRF in various formats (lomrf export).
7. Can compare MLN theories (lomrf diff).
8. Online supervision completion on semi-supervised training sets [currently experimental] (lomrf supervision)
