Data involving spatial and/or temporal attributes are often represented at different levels of granularity in different source schemata. In this work, a model of such multigranular data is developed, which supports not only the usual order structure on granules, but also lattice-like join and disjointness operators for relating such granules in much more complex ways. In addition, a model for m...

When data from several source schemata are to be integrated, it is essential that the resulting data in the global schema be consistent. This problem has been studied extensively for the monogranular case, in which all domains are flat. However, data involving spatial and/or temporal attributes are often represented at different levels of granularity in different source schemata. In this work, ...

Structure-mapping theory asserts that analogical comparison involves a process of structural alignment based on finding common relational structure (Gentner, 1983). During this process, correspondences are established between the aligned components of the analogs—both relations and objects. In the present experiment, we show that this alignment process is strikingly more efficient when the "cor...
