  Social media play a significant role in shaping public opinion and
influencing ideological communities through information propagation. Our demo
InfoPattern centers on the interplay between language and human ideology. The
demo (Code: https://github.com/blender-nlp/InfoPattern ) is capable of: (1) red
teaming to simulate adversary responses from opposite ideology communities; (2)
stance detection to identify the underlying political sentiments in each
message; (3) information propagation graph discovery to reveal the evolution of
claims across various communities over time. (Live Demo:
