Negation and Speculation Scope resolution

Negation and Speculation Scope resolution is a critical task in natural language processing aimed at accurately identifying and resolving the scope of negation and speculation expressions in sentences. The goal of this task is to enhance the precision of text understanding, ensuring that machines can correctly grasp the semantics and avoid ambiguities caused by misreading negations and speculations. Its application value is extensive, particularly in fields such as medical record analysis, sentiment analysis, and information retrieval, where it can significantly improve the reliability and accuracy of systems.
