Using Conceptual and Ontological Models for Tracking Changes of Spatio-Temporal Objects and Concepts over Time

چکیده
In this paper, we present a new approach that benefits from the advantages of both conceptual and ontological models in order to provide a powerful spatio-temporal data model for geographic information systems (GIS). We base our model on the MADS conceptual model that is transformed to a corresponding ontology model, using database to ontology mapping techniques and a set of transformation rules. The resulting ontology allows the system to be dynamic by adding or changing concepts. Our approach allows the tracking of historical changes of spatio-temporal objects and concepts over time by adding new explicit temporal relationships to the ontology.

Spatio-temporal analysis of the covid-19 impacts on the using Chicago urban shared bicycles by tensor-based approach
Cycling is a phenomenon in urban transportation that has the ability to allocate a specific location at any moment in time. Accordingly, spatial analysis of bicycle trips can be accompanied by temporal analysis. The use of a GIS environment is commonly recommended to display the extent of the phenomenon's spatial changes. However, in order to apply and display changes over time, it will requir...
متن کاملTowards An Ontology-Based Pivot Model for Spatio-Temporal Sources
The spectacular evolution of sensor networks and the proliferation of location-sensing devices in daily life activities are leading to an explosion of disparate spatio-temporal data. The collected data describes the movement of mobile objects used to construct what we call trajectory data. The diversity of these generated data has led to a variety of spatio-temporal models. In fact, the concept...

Considering the vast application of sea surface temperature in climatic and oceanic investigations, this parameter was studied in Oman Sea from 1986 to 2015. The SST was surveyed using trend analysis and Global and local Moran’s I spatial autocorrelation. In trend analysis, the Mann-Kendall test was used to determine the trend of SST changes and the Sen's Estimator method was used to examine th...

Objectives: The purpose of this study was to compare spatio-temporal gait parameters between elderly and young male subjects. Methods & Materials: 57 able-bodied elderly (72±5.5 years) and 57 healthy young (25±8.5 years) subjects participated in this study. A four segment model consist of trunk, hip, shank, and foot with 10 reflective markers were used to define lower limbs. Kinematic data c...
متن کاملMoving Objects Tracking Using Statistical Models
Object detection plays an important role in successfulness of a wide range of applications that involve images as input data. In this paper we have presented a new approach for background modeling by nonconsecutive frames differencing. Direction and velocity of moving objects have been extracted in order to get an appropriate sequence of frames to perform frame subtraction. Stationary parts of ...
