Computational Efficiency in Inferring Social Ties from Spatiotemporal Data.
MetadataShow full item record
The ability to infer social ties is useful for gaining insight into matters of social influence and the propagation of information. It is also useful in a variety of other fields, such as epidemiology, marketing, and criminology. With the increasing accessibility of GPS-enabled mobile devices and the growing popularity of location-based services, a new field of research regarding inferring real-world social ties from spatiotemporal data has emerged [1-4]. Proper attention to accuracy and efficiency in inferring social ties is essential for the technique to be useful in real-world scenarios. However, computational efficiency when computing co-occurrences based on massive amounts of spatiotemporal data, has been an often overlooked or understudied factor. This paper’s contribution is to survey prominent methods presented over the last two decades while analyzing how the method takes into account computational efficiency and, consequently, its usability with massive datasets. This survey then points the way towards fruitful areas for possible future research.
