Neural methods for SA have led to quantitative improvements over previous approaches, but
these advances are not always accompanied with a thorough analysis of the qualitative …

We present a neural end-to-end architecture for negation resolution based on a formulation
of the task as a graph parsing problem. Our approach allows for the straightforward inclusion …

In this paper, we evaluate the translation of negation both automatically and manually, in
English–German (EN–DE) and English–Chinese (EN–ZH). We show that the ability of …

Meaning banking--creating a semantically annotated corpus for the purpose of semantic
parsing or generation--is a challenging task. It is quite simple to come up with a complex …

Negation scope has been annotated in several English and Chinese corpora, and highly
accurate models for this task in these languages have been learned from these annotations …

Since the introduction of context-aware token representation techniques such as
Embeddings from Language Models (ELMo) and Bidirectional Encoder Representations …

Detecting instances of negation in text is crucially important for several applications, yet it is
often neglected. Several decades of research in automated negation detection have not yet …
