So, You Want to Compare Squiggly Lines? A Guide to Not Getting Lost in the Maze of Trajectory Similarity
The study found that the choice of similarity measure can significantly impact the results of trajectory analysis. Spatial differences between trajectories were found to be more influential than temporal differences in determining similarity. The paper provides recommendations for selecting and using trajectory similarity measures in practice.
Possible Conflicts of Interest
None identified
Identified Weaknesses
Limited number of trajectories
The experiments rely on a limited number of trajectories, which may not be representative of the broader population of trajectories. This limits the generalizability of the findings.
Arbitrary threshold selection
The choice of threshold values for LCSS and EDR is somewhat arbitrary and may influence the results. A more systematic approach to threshold selection would strengthen the findings.
Limited practical applications
The paper focuses primarily on the comparison of similarity measures and does not delve deeply into the specific applications or implications of the findings.
Rating Explanation
This paper provides a comprehensive and systematic analysis of trajectory similarity measures, covering conceptual, theoretical, and empirical perspectives. The experiments are well-designed and the findings are clearly presented. While there are some limitations, such as the limited number of trajectories used in the experiments and the arbitrary threshold selection, the overall quality of the research is high.
