Reproducibility Variable Result LLM Response
Research Type Experimental To illustrate the potential of our approach for OMQ answering, we implement a rewriting into an extension of Datalog for OMQs comprising reachability queries, and provide some promising evaluation results.

Pseudocode Yes Algorithm 1: Retrieve types that reach C through r
Open Source Code Yes We have implemented our approach in a prototype reasoner Mod4Q3 for the DL ALCH. 3http://www.kr.tuwien.ac.at/research/systems/Mod4Q/
Open Datasets Yes We considered some large realworld data sets, including NPD, a petroleum ontology, IMDb, a film ontology, and My ITS, a transport ontology. The first two were obtained from [Glimm et al., 2017] while the latter from [Bajraktari et al., 2017]. ... We took the 87 ontologies from the Oxford ontology library4 that have both ABox assertions... 4http://www.cs.ox.ac.uk/isg/ontologies/
Dataset Splits No The paper mentions evaluating on large real-world datasets but does not specify any training, validation, or test splits for data partitioning.
Hardware Specification Yes Experiments were run on a PC with an i7 2.4 GHz CPU running 64bit Linux Mint 17, with a JAVA heap space of 12GB.
Software Dependencies No The paper mentions 'Java', 'Postgre SQL database', and 'Clingo [Gebser et al., 2011]', but does not provide specific version numbers for Java or PostgreSQL, nor a precise version for Clingo itself.
Experiment Setup No The paper describes the general experimental design, including types of queries and data sources, but does not provide specific hyperparameter values, training configurations, or detailed system-level settings for the experiments.
