rio: Reasoner for Input/Output Logics

rio provides a TPTP-aligned [3] automated reasoning system for unconstrained and constrained I/O logics basid on the outi operators, 1 ≤ i ≤ 4. It is implemented as a Scala application and based on the scala-tptp-parser [4].

In short, the system allows you to specify a set of conditional norms and a number of inputs (each of which describing aspects of the current situational context), and provides automated means for inferring whether given obligations (also encoded as formulas) can be derived. rio can also be used to infer the set of detached obligations instead of checking detachment of given ones.
