Query Processing of Geosocial Data in Location-Based Social Networks

Arianna D’UliziaFernando Ferri e Patrizia Grifoni, hanno pubblicato sulla prestigiosa rivista MDPI – Academic Open Access Publishing, un articolo dal titolo: Query Processing of Geosocial Data in Location-Based Social Networks

“…The increasing use of social media and the recent advances in geo-positioning technologies have produced a great amount of geosocial data, consisting of spatial, textual, and social information, to be managed and queried. In this paper, we focus on the issue of query processing by providing a systematic literature review of geosocial data representations, query processing methods, and evaluation approaches published over the last two decades (2000–2020). The result of our analysis shows the categories of geosocial queries proposed by the surveyed studies, the query primitives and the kind of access method used to retrieve the result of the queries, the common evaluation metrics and datasets used to evaluate the performance of the query processing methods, and the main open challenges that should be faced in the near future. Due to the ongoing interest in this research topic, the results of this survey are valuable to many researchers and practitioners by gaining an in-depth understanding of the geosocial querying process and its applications and possible future perspectives…”
