Computational Assessment of Partisanship in News Titles

Hanjia Lyu*, Jinsheng Pan*, Zichen Wang*, Jiebo Luo

AAAI International Conference on Web and Social Media (ICWSM), 2024

We first adopt a human-guided machine learning framework to construct a new dataset for hyperpartisan news title detection with 2,200 manually labeled and 1.8 million machine-labeled titles that were posted from 2014 to 2022 by nine representative media organizations across three media bias groups - Left, Central, and Right. The fine-tuned transformer-based language model achieves an overall accuracy of 0.84 and an F1 score of 0.78 on the validation set. Next, we conduct a computational analysis to quantify the extent and dynamics of partisanship in news titles. While some aspects are as expected, our study reveals new or nuanced differences between the three media groups.

Understanding Divergent Framing of the Supreme Court Controversies: Social Media vs. News Outlets

Jinsheng Pan, Zichen Wang, Weihong Qi, Hanjia Lyu, Jiebo Luo

IEEE International Conference on Big Data (BigData), 2023

Understanding the framing of political issues is of paramount importance as it significantly shapes how individuals perceive, interpret, and engage with these matters. While prior research has independently explored framing within news media and by social media users, there remains a notable gap in our comprehension of the disparities in framing political issues between these two distinct groups. To address this gap, we conduct a comprehensive investigation, focusing on the nuanced distinctions both qualitatively and quantitatively in the framing of social media and traditional media outlets concerning a series of American Supreme Court rulings on affirmative action, student loans, and abortion rights.

Bias or Diversity? Unraveling Semantic Discrepancy in U.S. News Headlines

Jinsheng Pan*, Weihong Qi*, Zichen Wang, Hanjia Lyu, Jiebo Luo

Workshop on News Media and Computational Journalism (MEDIATE), AAAI International Conference on Web and Social Media (ICWSM), 2023

In this study, we analyzed 1.8 million news headlines from major U.S. media outlets between 2014 and 2022 to examine the semantic discrepancy. Multiple correspondence analysis (MCA) was applied, quantifying the semantic discrepancy in domestic politics, economic issues, social issues, and foreign affairs. Additionally, we compare the most frequent n-grams in media headlines to provide further qualitative insights.
