Researchers propose BERT-based system to detect Patronizing language
A new paper from arXiv introduces a system for automatically detecting patronizing and condescending language (PCL) in English and Mandarin. The authors note that PCL is a form of harmful speech that belittles vulnerable groups and reinforces stereotypes, making it difficult to identify even for human judges because it lacks the overt nature of hate speech.
Key points
- Researchers propose a system to detect patronizing and condescending language in English and Mandarin.
- The study compares static word embeddings with a convolutional neural network against fine-tuned BERT.
- The BERT-based approach achieved an F1 score of 0.528 on the development set.
The study evaluates two machine learning approaches. The first uses static word embeddings combined with a convolutional neural network. The second approach fine-tunes pre-trained BERT embeddings specifically for the PCL task. The researchers report that the BERT-based method was considerably more successful than the convolutional approach.
According to the abstract, the BERT model achieved an F1 score of 0.528 on the development set. This work contributes to the broader field of natural language processing by addressing a subtle but significant type of harmful language that current detection systems often miss.
