During the last years, the analysis of spatio-temporal data extracted from Online Social Networks (OSNs) has become a prominent course of action within the human-mobility mining discipline. Due to the noisy and sparse nature of these data, ...
Query the trajectory based on the precise track: a Bloom filter-based approach [0.03%]
基于布隆过滤器的精准轨迹查询方法

Zengjie Wang et al.
Fast and precise querying in a given set of trajectory points is an important issue of trajectory query. Typically, there are massive trajectory data in the database, yet the query sets only have a few points, which is a challenge for the s...

Addresses are the most common georeferencing resource people use to communicate to others a location within a city. Urban GIS applications that receive data directly from citizens, or from legacy information systems, need to be able to quic...
Mining Boundary Effects in Areally Referenced Spatial Data Using the Bayesian Information Criterion [0.03%]

Statistical models for areal data are primarily used for smoothing maps revealing spatial trends. Subsequent interest often resides in the formal identification of 'boundaries' on the map. Here boundaries refer to 'difference boundaries', r...
