We have implemented two versions of this general strategy: (i) pattern-based installments that always avoid object names in their initial expression and dynamically extend this if necessary, (ii) contextdependent installments that condition the initial expression on the complexity of the scene and extend the initial expression accordingly, inspired by standard approaches to attribute selection in REG (Krahmer and Van Deemter, 2012).
we do not test initial or reformulated expressions in isolation, but the strategy as a whole, which is similar to (Fang et al., 2014).
