Community-Specific Slang and Entity Detection via Semantic Shift in Fine-Tuned Language Models

This research proposes an unsupervised method to identify community-specific slang and unique entities by analyzing the magnitude of semantic shift. Semantic shift is defined as the evolution of a word's encoded representation after fine-tuning a pre-trained Large Language Model (LLM) on a community-specific text corpus.

Cognitive-Linguistic Indicators of Depression in Online Communities: Analysed by DistilBERT and Holographic Reduced Representation

This paper investigates whether combining cognitively grounded linguistic features with transformer-based embeddings improves automated detection of depression in online text. The study compares a TF-IDF baseline model with a hybrid DistilBERT HRR model, showing the latter achieves a significantly higher macro F1 score of 0.94.
