NegesAPI: An API for Negation Cue Detection and Scope Identification in Spanish

Resumen

This paper presents NegesAPI, an API for negation detection in Spanish. This API receives as input a text, analyzes it and automatically annotated it with the negation cues present in the text and their respective scopes of influence for their subsequent incorporation in Natural Language Processing systems. For the development of it, the SFU Review SP-NEG corpus and the negation model of Jiménez-Zafra et al. (2020a) have been updated. Moreover, it has been created a web application with the API documentation, a tutorial and a user management system to monitor the API usage.
