The analysis of mobility patterns from large-scale spatio-temporal datasets is key to personalised location-based applications. Datasets capturing user location are, however, often incomplete due to temporary failures of sensors, deliberate interruptions or because of data privacy restrictions. Effective location imputation is thus a critical processing step enabling mobility pattern mining from sparse data. To date, most studies in this area have focused on coarse location prediction at city scale. In this paper we aim to infer the missing location information of individuals tracked within structured, mostly confined spaces such as a university campus or a mall. Many indoor tracking dataset..View full abstract
