Dividing and Conquering the Layered Land - Franceschet (Correct)
....and diagnosis can be formulated as temporal constraint satisfaction problems, often involving multiple time granularities. In a temporal constraint satisfaction problem, variables are used to represent event occurrences and constraints are used to represent their granular temporal relationships [6, 25, 38, 59, 82, 101, 105, 110]. Finally, shifts in the temporal perspective occur very often in natural language communication, and thus the ability of supporting and relating a variety of temporal models, at di#erent grain sizes, is a relevant feature for the task of natural language understanding [10, 47, 53] Any time ....

Modeling Moving Objects over Multiple Granularities - Hornsby, Egenhofer (Correct)
....the spatial aspects of objects at different Kathleen Hornsby and Max Egenhofer Annals of Mathematics and Artificial Intelligence granularities. The temporal aspects of a scenario of movement are also very relevant and efforts have been made to provide a formal framework for temporal granularity [18 20]. Typically, of course, movement involves both spatial and temporal elements and ideally, data models should provide support for both dimensions combined. At refined granularities, for example, a view of a person s movement may include the time and place of departure, mode(s) of transport, time ....

Temporal Generalization with Domain Generalization Graphs - Randall, Hamilton, Hilderman (Correct)
....These ideas form the basis for our granularity generalization technique, as given in Section 3. Bettini et al. define a convenient operator for upward changes in temporal granularity; e.g. dze month second gives the value in the month domain corresponding to the value z in the second domain [1, 2]. They also note that the set of all temporal types forms a lattice with respect to their finer than relation, although they do not develop this notion. Cukierman and Delgrande [4, 5] construct a calendar structure and calendar expressions that form the basis for our definition of a calendar DGG. ....

Managing Temporal Values on Top of OO DBMS - Canavaggio, Dumas (1998) (Correct)
....at the application level by adding specialized classes which include conversion methods. From a formal viewpoint, the notion of time granularity has been extensively studied in the domain of temporal databases [CR87, WJS95, GLOS97] and by the temporal reasoning community [Hob85a, Euz93a, BWJ96] In temporal databases, most studies adopt a discrete and linear model of time and define granularities as partitions over this structure [WJS95] In this respect, the works around TIGUKAT [GO93, GLOS97] are an exception : the temporal type lattice is structured so that it is possible to add ....
