A Formal Model for Representing Point Trajectories in Two-Dimensional Spaces
Modelling moving points is a subject of interest that has attracted a wide range of spatio-temporal database research. Efforts...
A Logical Approach for Modeling Spatio-temporal Objects and Events
The formal specification of spatio-temporal information is essential to the definition of spatio-temporal database systems. The main contribution of...
Conceptual Neighbourhood Diagrams for Representing Moving Objects
The idea of Conceptual Neighbourhood Diagram (CND) has proved its relevance in the areas of qualitative reasoning about time...
A Refined Line-Line Spatial Relationship Model for Spatial Conflict Detection
In order to detect the spatial conflicts in the process of spatial database updating, a refined description of spatial...
Assessing Topological Consistency for Collapse Operation in Generalization of Spatial Databases
Generalization of spatial databases consists of complicated operations including not only geometric transformations but also topological changes. The changes...
Spatial Relations for Semantic Similarity Measurement
Measuring semantic similarity among concepts is the core method for assessing the degree of semantic interoperability within and between...
Approximate Continuous K Nearest Neighbor Queries for Continuous Moving Objects with Pre-defined Paths
Continuous K nearest neighbor queries (C-KNN) on moving objects retrieve the K nearest neighbors of all points along a...
Modeling Dynamic Engineering Design Processes in PSI
One way to make engineering design effective and efficient is to make its processes flexible – i.e. self-adjusting, self-configuring,...
Spatio-temporal Similarity Analysis Between Trajectories on Road Networks
In order to analyze the behavior of moving objects, a measure for determining the similarity of trajectories needs to...
Preliminary Basis for an Ontology-Based Methodological Approach for Multi-agent Systems
The influence of ontologies in Knowledge Based Systems (KBS) methodologies extends well beyond the initial analysis phase, leading in...
