Reproducibility Variable Result LLM Response
Research Type Experimental Using a prototype implementation, experiments were performed over a corpus of real world ontologies to investigate the practicality of both approaches across several settings.

Pseudocode Yes Figure 1: Int ALC rules utilised in our abduction method.
Open Source Code No A Java prototype was implemented using the OWLAPI1 and the forgetting tool LETHE which implements the Int ALC method.2
Open Datasets Yes The final corpus contains ontologies from the NCBO Bioportal and OBO repositories,34 and the LUBM (Guo, Pan, and Heflin 2005) and Semintec ontologies.5
Dataset Splits No The paper describes how '30 consistent, non-entailed observations were randomly generated' for experiments, but it does not specify explicit train/validation/test dataset splits or their percentages/counts.
Hardware Specification Yes The experiments were performed on a machine using a 4.00GHz Intel Core i7-6700K CPU and 16GB RAM.
Software Dependencies No The paper states 'A Java prototype was implemented using the OWLAPI1 and the forgetting tool LETHE which implements the Int ALC method.2', but it does not specify version numbers for Java, OWLAPI, or LETHE.
Experiment Setup Yes For each ontology, 30 consistent, non-entailed observations were randomly generated using any ALC concepts from the associated ontology, some of which were combined using ALC operators to encourage variety. ... For the first experiment, F was set to one random concept symbol from sig(ψ). ... For the filtering in Step (2), the preference relation used in these experiments was simply based on order of appearance of each disjunct. ... In all cases, LETHE was subject to a 300 second time limit.
