Towards Semantic Trajectory Outlier Detection

چکیده
Volunteered Geographic Information (VGI) is a Web phenomenon known as “user-generated content”, which involves resources from Web 2.0 and geographic data. Geobrowsers are websites that collect and provide VGI. These systems, however, do not follow norms or standards for data collection or documentation, which makes it difficult to recover such data and limits the interoperability among VGI systems. In addition, the quality of the data collected by VGI systems has often been questioned. This paper proposes the DM4VGI, a template for creating dynamic metadata from volunteered geographic information provided by users through Geobrowsers or Virtual Globes. The DM4VGI is used to document and validate the quality of the VGI, as well as to facilitate data interoperability.

Discovering Semantic Spatial and Spatio-Temporal Outliers from Moving Object Trajectories
Several algorithms have been proposed for discovering patterns from trajectories of moving objects, but only a few have concentrated on outlier detection. Existing approaches, in general, discover spatial outliers, and do not provide any further analysis of the patterns. In this paper we introduce semantic spatial and spatio-temporal outliers and propose a new algorithm for trajectory outlier d...
متن کاملTrajectory Outlier Detection Algorithm Based on Structural Features
As the development of location based service, such as GPS and RFID, a great volume of trajectory data can be collected. As a result, mining knowledge from these data has become an attractive topic. The trajectory outlier detection algorithm, proposed in this paper, can be used to detect trajectory outliers by comparing the structure between each trajectory segment pairs. Firstly, a new concept ...
متن کاملOnline Detection of Anomalous Sub-trajectories: A Sliding Window Approach Based on Conformal Anomaly Detection and Local Outlier Factor
Automated detection of anomalous trajectories is an important problem in the surveillance domain. Various algorithms based on learning of normal trajectory patterns have been proposed for this problem. Yet, these algorithms suffer from one or more of the following limitations: First, they are essentially designed for offline anomaly detection in databases. Second, they are insensitive to local ...
متن کاملDiscovering Trajectory Outliers between Regions of Interest
Different algorithms have been proposed in the last few years for discovering different types of behaviors in trajectory data. Existing approaches, in general, deal only with the outliers, and do not consider the standards routes and regions of interest. In this paper we propose a new algorithm for trajectory outlier detection between regions of interest. We show with two experiments on real da...
متن کاملAutomated Entropy Value Frequency (AEVF) Algorithm for Outlier Detection in Categorical Data
Outlier detection has been a very important concept in data mining. The aim of outlier detection is to find those objects that are of not the norm. There are many applications of outlier detection from network security to detecting credit fraud. However most of the outlier detection algorithms are focused towards numerical data and do not perform well when applied to categorical data. In this p...
