On the Expressiveness of MTL Variants over Dense Time
The basic modal operator bounded until of Metric Temporal Logic (MTL) comes in several variants. In particular it can be strict (when it does not constrain the current instant) or...

A Fuzzy Model for Representing Uncertain, Subjective, and Vague Temporal Knowledge in Ontologies
Abstract. Time modeling is a crucial feature in many application domains. However, temporal information often is not crisp, but is uncertain, subjective and vague. This is particul...
