Research Type Theoretical In this paper, we investigate temporal queryby-example by focusing on the basic but very useful case where data D is a set of timestamped atomic propositions. Our query languages are positive fragments of linear temporal logic LTL with the temporal operators (eventually), (next), and U (until) interpreted under the strict semantics [Demri et al., 2016].We take the first steps towards understanding the complexity and especially feasibility of the queryby-example problems QBE(L, Q) with L an ontology and Q a query language. We are particularly interested in whether there is a difference in complexity between path and branching queries and whether it can be reduced by bounding the number of positive or negative examples. Our results in the ontology-free case are summarised in Table 1Our proof techniques range from reductions to common subsequence existence problems [Maier, 1978; Fraser, 1996] and dynamic programming to mimicking separability by path and branching U-queries in terms of containment and simulation of transition systems [Kupferman and Vardi, 1996].
