In this work, we revisit Shared Task 1 from the 2012 * SEM Conference: the au- tomated analysis of negation. Unlike the vast majority of participating systems in 2012, our approach works over explicit and formal representations of proposi- tional semantics, i.e. derives the notion of negation scope assumed in this task from the structure of logical-form meaning rep- resentations. We relate the task-specific interpretation of (negation) scope to the concept of (quantifier and operator) scope in mainstream underspecified semantics. With reference to an explicit encoding of semantic predicate-argument structure, we can operationalize the annotation deci- sions made for the 2012 * SEM task, and demonstrate how a comparatively simple system for negation scope resolution can be built from an off...
