Modeling Surface Hydrology Concepts with Endurance and Perdurance,The paper demonstrates the usefulness of applying the notions of endurance and perdurance to surface hydrology. The result is a set of primitive entities, aggregate entities, and relations between these entities that are necessary to cover surface hydrology concepts.

Project Lachesis: Parsing and Modeling Location Histories, a subject has spent some time at a single location, and . are clusters of stays. Using stays and destinations, we then propose two methods for modeling location histories probabilistically. Experiments show the value of these data structures, as well as the possible applications of probabilistic models of location histories.

Zusammenfassung der Ergebnisse,g such an approach is to ensure the right correspondence of data across databases. To reach this goal, it is necessary to develop a description of the surface hydrology concepts that is internally consistent and semantically rich. In this paper, we apply the notions of endurance and perdurance to mo

A simple comparison of task requirements and available data quality is supplemented with general, common-sense knowledge about effects of errors, lack of precision in the data and the dilution of quality over time.
