MANDOLIN
Markov Logic Networks for the Discovery of Links.
Requirements
- Java 1.8+
- PostgreSQL 9.4.x
- Gurobi solver
- Maven
- Wget, Unzip
Quick start
- Download and decompress Mandolin v0.4.0-alpha
- Run
bash install.sh
Experiments
The following command will discover new links of any predicate (--aim) on the WordNet dataset (--input) with mining threshold 0.8 (--mining) and 1 million Gibbs sampling iterations (--sampling).
java -Xmx1g -jar target/Mandolin-0.4.0-jar-with-dependencies.jar plain --input data/benchmark/wn18/wordnet-mlj12-train.nt,data/benchmark/wn18/wordnet-mlj12-valid.nt --output eval/wn18 --mining 0.8 --sampling 1000000 --aim "*"
Discovered links can be found in the --output folder at ./eval/wn18/discovered_X.nt, where X is the output threshold, meaning that a file contains all links whose confidence is greater or equal than X.
An excerpt of the discovered rules and weights:
0.990517419 wn18:_part_of(b, a) => wn18:_has_part(a, b)
0.862068966 wn18:_instance_hypernym(a, c) AND wn18:_synset_domain_topic_of(f, b) => wn18:_synset_domain_topic_of(a, b)
An excerpt of the discovered links with confidence > 0.9:
wn18:08131530 wn18:_has_part wn18:08132046 .
wn18:09189411 wn18:_has_part wn18:08707917 .
wn18:10484858 wn18:_synset_domain_topic_of wn18:08441203 .

Basic documentation
Mandolin can be launched as follows.
java -Xmx1g -jar target/Mandolin-0.4.0-jar-with-dependencies.jar <GOAL> <PARAMETERS>
Goals
| Goal | Description |
|---|---|
plain | Launch a plain Mandolin execution. |
eval | Evaluate MRR and hits@k. |
Plain execution
Parameters for plain goal:
| Parameter | Description | Example value |
|---|---|---|
--input | Comma-separated N-Triple files. | data1.nt,data2.nt |
--output | Workspace and output folder. | eval/experiment1 |
--aim | Aim predicate. For all predicates use wildcard *. | http://www.w3.org/2002/07/owl#sameAs |
--mining | Rule mining threshold. | 0.9 (default: 0.0 support) |
--sampling | Gibbs sampling iterations. | 1000000 (default: 100 x evidence size) |
--rules | Maximum number of rules. | 1500 (default: none) |
--sim | Enable similarity among literals as min,step,max. | 0.8,0.1,0.9 (default: none) |
--onto | Enable ontology import. | true (default: false) |
--fwc | Enable forward-chain. | true (default: false) |
Evaluation
The eval goal takes two parameters: the N-Triples file of the test set and Mandolin's output directory.
Example run:
java -Xmx1g -jar target/Mandolin-0.4.0-jar-with-dependencies.jar eval data/benchmark/wn18/wordnet-mlj12-test.nt eval/wn18
Manual install
