Abstract

ABSTRACT Measuring similarity of GPS trajectories has attracted a lot of attention in recent years. As a result, multiple trajectory similarity measures have been developed and are used in a wide set of applications which aim to extract meaningful information from large collections. In this paper, we focus on some of the most popular measures and study how they all can be adapted to use contextual information. We experiment using the buildings in an urban setting as the context and demonstrate how it impacts the similarity values. Experiments show that routes rank differently in terms of similarity in the presence of context which can have serious implications in applications such as trajectory search and clustering similar trajectories.

GPS轨迹的上下文感知相似性

摘要近年来，测量GPS轨迹的相似性引起了人们的广泛关注。因此，已经开发了多个轨迹相似性度量，并在一系列广泛的应用中使用，这些应用旨在从大型集合中提取有意义的信息。在这篇论文中，我们重点研究了一些最流行的测量方法，并研究了它们如何适应上下文信息的使用。我们使用城市环境中的建筑作为背景进行实验，并演示它如何影响相似性值。实验表明，在上下文存在的情况下，路线在相似性方面排名不同，这可能对轨迹搜索和聚类相似轨迹等应用产生严重影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
