Abstract

fetched live from OpenAlex

The emergence of social networking sites has paved the way for researchers to collect and analyze massive data volumes. Twitter, being one of the leading micro-blogging sites worldwide, provides an excellent opportunity for its users to express their states of mind via short text messages known as tweets. Much research focusing on identifying emotions and sentiments conveyed through tweets has been done. We propose a BERT model fine-tuned to the emotion recognition and sentiment classification tasks and show that it performs better than previous models on standard datasets. We also explore the effectiveness of data augmentation and data enrichment for these tasks.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
