  • Temporal data can be found in various sources from patient histories, purchase histories, employee histories, to web logs. [...] Key Method In this work, we use a numerical extension of Markov logic networks to provide formal syntax and semantics for uncertain temporal kgs. Moreover, we propose a set of datalog constraints with inequalities, that extend the underlying schema of the kgs and help in resolving conflicting facts. Finally, we characterize the complexity of two important queries, maximum a-posteriori…Expand Abstract
