Fine-Grained Analysis of Propaganda in News Articles 

@EMNLP'19

Our previous work on propaganda has addressed propaganda detection at the document level.

We propose a novel task: performing fine-grained analysis of texts by detecting all fragments that contain propaganda techniques as well as their type. In particular, we create a corpus of news articles manually annotated at the fragment level with eighteen propaganda techniques and we propose a suitable evaluation measure.  

We further design a novel multi-granularity neural network, and we show that it outperforms several strong BERT-based baselines.

Code and Data

 The code used in the experiments is available here. Since we are running a shared task using part of the test set, we temporarely removed it.

Demo
