Spatial-Temporal Cluster Relations -- A Foundation for Trajectory Cluster Lifetime Analysis
Ivens Portugal, Paulo Alencar, Donald Cowan
Spatial-temporal data, that is information about objects that exist at a particular location and time period, are rich in value and, as a consequence, the target of so many initiat…
Cluster Lifecycle Analysis: Challenges, Techniques, and Framework
Ivens Portugal, Paulo Alencar, Donald Cowan
Novel forms of data analysis methods have emerged as a significant research direction in the transportation domain. These methods can potentially help to improve our understanding…
Developing a Spatial-Temporal Contextual and Semantic Trajectory Clustering Framework
Ivens Portugal, Paulo Alencar, Donald Cowan
This paper reports on ongoing research investigating more expressive approaches to spatial-temporal trajectory clustering. Spatial-temporal data is increasingly becoming universal…
