ULD@NUIG at SemEval-2020 Task 9: Generative Morphemes with an Attention Model for Sentiment Analysis in Code-Mixed Text
This addresses sentiment analysis for multilingual social media users, but it is incremental as it builds on existing methods for code-mixed text.
The paper tackled sentiment analysis in English-Hindi code-mixed tweets by proposing the Generative Morphemes with Attention (GenMA) model, which automatically infers language tags without explicit word-level labels and outperformed baseline F1-scores on test and validation datasets.
Code mixing is a common phenomena in multilingual societies where people switch from one language to another for various reasons. Recent advances in public communication over different social media sites have led to an increase in the frequency of code-mixed usage in written language. In this paper, we present the Generative Morphemes with Attention (GenMA) Model sentiment analysis system contributed to SemEval 2020 Task 9 SentiMix. The system aims to predict the sentiments of the given English-Hindi code-mixed tweets without using word-level language tags instead inferring this automatically using a morphological model. The system is based on a novel deep neural network (DNN) architecture, which has outperformed the baseline F1-score on the test data-set as well as the validation data-set.
