- Title: Text and Causal Inference: A Review of Using Text to Remove Confounding
from Causal Estimates
- Authors: Katherine A. Keith, David Jensen, Brendan O'Connor
- Abstract summary: An individual's entire history of social media posts or the content of a news article could provide a rich measurement of confounders.
Despite increased attention on adjusting for confounding using text, there are still many open problems.

- Abstract: Many applications of computational social science aim to infer causal
conclusions from non-experimental data. Such observational data often contains
confounders, variables that influence both potential causes and potential
effects. Unmeasured or latent confounders can bias causal estimates, and this
has motivated interest in measuring potential confounders from observed text.
For example, an individual's entire history of social media posts or the
content of a news article could provide a rich measurement of multiple
confounders. Yet, methods and applications for this problem are scattered
across different communities and evaluation practices are inconsistent. This
review is the first to gather and categorize these examples and provide a guide
to data-processing and evaluation decisions. Despite increased attention on
adjusting for confounding using text, there are still many open problems, which
we highlight in this paper.

Susceptibility to misinformation describes the degree of belief in unverifiable claims that is not observable.
Existing susceptibility studies heavily rely on self-reported beliefs.
We propose a computational approach to model users' latent susceptibility levels.

We present a new task, Response Forecasting on Personas for News Media, to estimate the response a persona might have upon seeing a news message.
The proposed task not only introduces personalization in the modeling but also predicts the sentiment polarity and intensity of each response.
This enables more accurate and comprehensive inference on the mental state of the persona.

We propose D-BIAS, a visual interactive tool that embodies human-in-the-loop AI approach for auditing and mitigating social biases.
A user can detect the presence of bias against a group by identifying unfair causal relationships in the causal network.
For each interaction, say weakening/deleting a biased causal edge, the system uses a novel method to simulate a new (debiased) dataset.
