The Family History Knowledge Base (FHKB) was presented at OWLED in 2008. The FHKB uses a rich object property hierarchy, including many OWL 2 features, to derive many entailments on some 450 individuals representing the Stevens family. In the ABox, only par- ent relationships and some sibling relationships (either isSisterOf or isBrotherOf) are asserted. Using a sparse assertion of brother or sis- ter relationships, together with information about gender, other sibling relationships should be able to be inferred. The inability to do this in OWL has been described as the 'Man-Man' problem, and various work- arounds have been discussed. We describe a new solution to this issue, implemented in the reasoner FaCT++. This solution allows to capture axioms such as 'My male siblings are my brothers', and we have added them to the FHKB. The number of entailments about, for instance, sib- ling relationships increases significantly without increasing the number of asserted facts about members of the Stevens family. |
