摘要:

本文介绍了我们的系统(MIC-CIS)的细节和参与细粒度宣传检测共享任务2019的结果。为了解决句子(SLC)和片段级(FLC)宣传检测的任务,我们探索了不同的神经架构(例如,CNN、LSTM-CRF和BERT)并提取语言(例如,词性、命名实体、可读性、情感、情绪等),布局和专题功能。具体来说,我们设计了多粒度和多任务神经架构,以联合执行句子和片段级别的宣传检测。此外,我们研究了不同的集成方案,如多数表决,松弛表决等,以提高整体系统的性能。与其他参与系统相比,我们的提交在FLC和SLC任务中分别排名第三和第四。

英文摘要:

This paper describes our system (MIC-CIS) details and results of participation in the fine-grained propaganda detection shared task 2019. To address the tasks of sentence (SLC) and fragment level (FLC) propaganda detection, we explore different neural architectures (e.g., CNN, LSTM-CRF and BERT) and extract linguistic (e.g., part-of-speech, named entity, readability, sentiment, emotion, etc.), layout and topical features. Specifically, we have designed multi-granularity and multi-tasking neural architectures to jointly perform both the sentence and fragment level propaganda detection. Additionally, we investigate different ensemble schemes such as majority-voting, relax-voting, etc. to boost overall system performance. Compared to the other participating systems, our submissions are ranked 3rd and 4th in FLC and SLC tasks, respectively.
