We propose CHRONOS, a system for reasoning over temporal information in OWL ontologies. Representing both qualitative temporal (i.e., information whose temporal extents are unknown such as “before”, “after” for temporal relations) in addition to quantitative information (i.e., where temporal information is defined precisely e.g., using dates) is a(More)
We investigate on potential improvements to reasoning about qualitative temporal information in OWL. Building upon path consistency, the new reasoner design, referred to as CHRONOS, computes a minimal set of relation compositions at run-time (based on a tractable subset of Allen relations) while being sound and complete. The experimental results demonstrate(More)
