Query: HeBERT & HebEMO: a Hebrew BERT Model and a Tool for Polarity Analysis
  and Emotion Recognition   This paper introduces HeBERT and HebEMO. HeBERT is a Transformer-based model
for modern Hebrew text, which relies on a BERT (Bidirectional Encoder
Representations for Transformers) architecture. BERT has been shown to
outperform alternative architectures in sentiment analysis, and is suggested to
be particularly appropriate for MRLs. Analyzing multiple BERT specifications,
we find that while model complexity correlates with high performance on
language tasks that aim to understand terms in a sentence, a more-parsimonious
model better captures the sentiment of entire sentence. Either way, out
BERT-based language model outperforms all existing Hebrew alternatives on all
common language tasks. HebEMO is a tool that uses HeBERT to detect polarity and
extract emotions from Hebrew UGC. HebEMO is trained on a unique
Covid-19-related UGC dataset that we collected and annotated for this study.
Data collection and annotation followed an active learning procedure that aimed
to maximize predictability. We show that HebEMO yields a high F1-score of 0.96
for polarity classification. Emotion detection reaches F1-scores of 0.78-0.97
for various target emotions, with the exception of surprise, which the model
failed to capture (F1 = 0.41). These results are better than the best-reported
performance, even among English-language models of emotion detection.
