Business Insights through Text
The BIT LAB

We explore, examine, and extract consumer behavior or market insights through abundantly available, yet severely untapped text data. Via a variety of methodologies including causal inference, generative models, deep learning, neural NLP, bayesian statistics, interpretable machine learning, etc spanning topics such as social media analytics, digital consumer management, persuasion, patents, and promotion, our studies are focused on providing empirical evidence and empirical generalization to develop or extend consumer behavior and market theories. 

Doctoral Students

Emaad Manzoor

Emaad Manzoor is a PhD student in Information Systems at the Heinz College, CMU. He works on machine learning and causal inference methodology for data with complex structure, such as networks and text. Substantively, he examines causal questions pertaining to persuasion and its linguistic determinants.

Update: Dr Manzoor has graduated and is a professor at U of Wisconsin-Madison

Zhaoqi Cheng

Zhaoqi Cheng is a PhD student in Business Technology at Tepper School of Business, CMU.
