| |  | | Sequence Alignment as a Method for Human Activity Analysis in Space and Time read moreAbstract: Jun 2007. This article introduces the method of sequence alignment as a tool for analyzing the sequential aspects within the temporal and spatial dimensions of human activities. Sequence alignment was first developed during the 1980s and employed by biochemists to ... | 2007 |

| | | Jensen, Christian S. | A Conceptual Schema Language for the Management of Multiple Representations of Geographic Entities read moreAbstract: Multiple representation of geographic information occurs when a real-world entity is represented more than once in the same or different databases. This occurs frequently in practice, and it invariably results in the occurrence of inconsistencies among the different representations of the same entity. In this paper, we propose an approach to the modeling of multiple represented entities, which is based on the relationships among the entities and their representations. Central to our approach is the Multiple Representation Schema Language that, by intuitive and declarative means, is used to specify rules that match objects representing the same entity, maintain consistency among these representations, and restore consistency if necessary. The rules configure a Multiple Representation Management System, the aim of which is to manage multiple representations over a number of autonomous federated databases. We present a graphical and a lexical binding to the schema language. The graphical binding is built on an extension to the Unified Modeling Language and the Object Constraint Language. We demonstrate that it is possible to implement the constructs of the schema language in the object-relational model of a commercial RDBMS. | 2005 |

| | | Worboys, Michael | Event-oriented approaches to geographic phenomena read moreAbstract: This paper is about the information-theoretic foundations upon
which useful explanatory and predictive models of dynamic geographic
phenomena can be based. It traces the development over the last
decade or so of these foundations, from sequences of temporal snapshots,
through object life histories, to event chronicles. A crucial ontological
distinction is drawn between “things” and “happenings”, that is
between continuant and occurrent entities. Most of the work up to now
has focused on representing the evolution through time of geographic
things, whether objects or fields. This paper argues that happenings
should be upgraded to an equal status with things in dynamic geographic
representations, and suggests ways of doing this. The main
research focus of the paper is the application of an algebraic approach,
previously developed mainly in the context of computational processes,
to real-world happenings. It develops a pure process theory of space
and time, and demonstrates its applicability by providing an example
of the representation of motion of a vehicle through a region. The
paper concludes by noting some of the requirements for scaling this
approach to real-world dynamic scenarios, such as might be found, for
example, in the automation of coordination of disaster relief. | 2005 |

| | | Jacquez, Geoffrey M. | Design and Implementation of Space-Time Information Systems read moreAbstract: we discuss issues in designing data structures, indexing, and queries for spatiotemporal data. We describe a space-time object model that treats observations on objects as a chain, with each link consisting of one subobject at each time point/interval. Object morphing (change in shape) in urban settings is effective for modeling changes in geopolitical units through time and for representing urban growth or decline. Movement models for these objects are functions that may be simple (e.g. linear, using vector representation) or complex, involving non-linear dynamics. We derive spatial, temporal, and spatio-temporal queries emergent from the data model, and their implementation in a k-dimensional Hilbert R-tree. We demonstrate this approach in a representative application, a simulation of the spread of influenza in a hospital ward. This approach efficiently handles simulated spatio-temporal data, demonstrating the robustness of the query structure. | 2004 |

| | | Grenon, Pierre | SNAP and SPAN: Towards Dynamic Spatial Ontology read moreAbstract: We propose a modular ontology of the dynamic features of reality. This
amounts, on the one hand, to a purely spatial ontology supporting snapshot views of the world at successive instants of time and, on the other hand, to a purely spatiotemporal ontology of change and process. We argue that dynamic spatial ontology must combine these two distinct types of inventory of the entities and relationships in reality, and we provide characterizations of spatiotemporal reasoning in the light of the interconnections between them. | 2004 |

We integrated various kinds of works related to moving objects into one system, and newly proposed a data model for moving objects, a location query language, an indexing framework, and a method for storing moving objects. The system we proposed supports a diverse set of location acquisition policies, location indexes and location storages. | 2004 |

| | | altenis, Simonas | Indexing of Moving Objects for Location-Based Services read moreAbstract: This paper assumes an Internet-service scenario where objects that have not reported their position within a specified duration of time are expected to no longer be interested in, or of interest to, the service. Due to the possibility of many “expiring” objects, a highly dynamic database results. The paper presents an R-tree based technique for the indexing of the current positions of such objects. Different types of bounding regions are studied, and new algorithms are provided for maintaining the tree structure. Performance experiments indicate that, when compared to the approach where the objects are not assumed to expire, the new indexing technique can improve search performance by a factor of two or more without sacrificing update performance. | 2002 |
