Consistent Queries over Cardinal Directions across Different Levels of Detail
Current models for cardinal directions, such as north and northeast, are either point-based or region-based, but no models exist that apply equally, independent of the geometric d...

An Algebraic Formulation of Temporal Knowledge for Reasoning about Recurring Events
We formulate an algebra of binary temporal relations between events the number of occurrences of which is unknown, but which are known to recur in time. Ontologically, we view the...
