Fuzzy-Rough Nearest Neighbour Approaches for Emotion Detection in Tweets

Code for the paper written by Olha Kaminska, Chris Cornelis, and Veronique Hoste and presented at IJCRS 2021 conference, organized jointly with IFSA-EUSFLAT 2021.

The task is based on SemEval-2018 Task 1: Affect in Tweets competition. We chose the ordinal classification Task EI-oc: Detecting Emotion Intensity.

Abstract

Social media are an essential source of meaningful data used in different tasks such as sentiment analysis and emotion recognition. Mostly, these tasks are solved with deep learning methods. Due to the fuzzy nature of textual data, we consider using classification methods based on fuzzy rough sets.

Specifically, we develop an approach for the SemEval-2018 emotion detection task, based on the fuzzy rough nearest neighbour (FRNN) classifier enhanced with ordered weighted average (OWA) operators. We use tuned ensembles of FRNN-OWA models based on different text embedding methods. Our results are competitive with the best SemEval solutions based on more complicated deep learning methods.
