Logical complement semantics is referred to as the meaning expressed by elements of negation, degree, tense and aspect, modality and mood that are attached to a basic predicate-centered proposition in a sentence. It is embodied as the semantic constraint relation between logical semantic operators and the predicate. Logical complement semantics as an effective supplement of semantic relations expressed by elements in a basic proposition is important for deep understanding of sentence semantics. This paper proposes a Chinese logical complement semantic annotation framework for deep semantic understanding. Specifically, classification systems and operator dictionaries are constructed for representing negation, degree, tense and aspect, and mood based on existing research results. Annotation rules are established to annotate logic complement semantics for the sentences which have been tagged for basic propositional arguments. Finally, the statistics of annotation results is presented, and the problems in annotation process are also analyzed.
