An Approach to gecoding based on volunteered Spatial Data
The automated process of assigning geographic coordinates to textual descriptions of a place, generally referred to as geocoding, plays an important role in various fields of geographic information technologies, ranging from the analysis of healths records [28] or crime incidents [17] to location based services like route planning applications [20]. However, since the collection and maintenance...
متن کاملProtecting Location Privacy in Spatial Crowdsourcing using Encrypted Data
In spatial crowdsourcing, spatial tasks are outsourced to a set of workers in proximity of the task locations for efficient assignment. It usually requires workers to disclose their locations, which inevitably raises security concerns about the privacy of the workers’ locations. In this paper, we propose a secure SC framework based on encryption, which ensures that workers’ location information...
متن کاملPerform Three Data Mining Tasks with Crowdsourcing Process
For data mining studies, because of the complexity of doing feature selection process in tasks by hand, we need to send some of labeling to the workers with crowdsourcing activities. The process of outsourcing data mining tasks to users is often handled by software systems without enough knowledge of the age or geography of the users' residence. Uncertainty about the performance of virtual user...
متن کاملThe use of Volunteered Geographic Information and Crowdsourcing in Disaster Management: a Systematic Literature Review
The number of crisis events around the world has been increasing in the last years and suggests there is a real need to make communities more resilient to them. In addition to providing conventional authoritative data, ordinary citizens and residents in the affected areas are also voluntarily supplying information about the affected areas, in what has been called Crowdsourced or Volunteered Geo...
متن کاملConfronting the data-divide in a time of spatial turns and volunteered geographic information
Geography is enjoying a period of unparalleled visibility, driven by the growing use of geographic methods and concepts across the sciences and humanities—the so-called spatial turn—and the pervasive use of geospatial Web technologies and their concomitant influence on society, especially the phenomenon of volunteered geographic information (VGI). The field of public health is beginning to harn...
