autoLIB-psych 1.0.0

A Python package for automated detection of Linguistic Intergroup Bias (LIB) in text data using sentence-level sentiment and word-level abstraction analysis. Designed for research on language bias in news media and social discourse.

Automated Linguistic Intergroup Bias Detection in Text

autoLIB is a Python package for detecting linguistic intergroup bias (LIB) in natural language text. It combines rule-based abstraction coding (via the Linguistic Category Model) with sentence-level sentiment analysis to produce interpretable metrics of language bias. The package is designed to support social psychology, media studies, and computational linguistics research.

✨ Features

• 📄 Sentence-level valence classification using VADER or Stanza sentiment models.
• 🔤 Word-level abstraction scoring based on the Linguistic Category Model (LCM).
• 🧠 Bias index computation: compares abstraction in desirable vs. undesirable descriptions.
• 🔍 Keyword-driven sentence filtering to isolate relevant parts of text.
• 📊 Outputs sentence-level results and overall summary statistics.
• 🧪 Designed with transparency, replicability, and academic applications in mind.

	abstract = {Linguistic bias is the differential use of abstraction, or other linguistic mechanisms, for the same behavior by members of different groups. Abstraction is defined by the Linguistic Category Model (LCM), which defines a continuum of words from concrete to abstract. Linguistic Intergroup Bias (LIB) characterizes the tendency for people to use abstract words for undesirable outgroup and desirable ingroup behavior and concrete words for desirable outgroup and undesirable ingroup behavior. Thus, by examining abstraction in a text, we can understand the implicit attitudes of the author. Yet, research is currently stifled by the time-consuming and resource-intensive method of manual coding. In this study, we aim to develop an automated method to code for LIB. We compiled various techniques, including forms of sentence tokenization, sentiment analysis, and abstraction coding. All methods provided scores that were a good approximation of manually coded scores, which is promising and suggests that more complex methods for LIB coding may be unnecessary. We recommend automated approaches using CoreNLP sentiment analysis and LCM Dictionary abstraction coding.},
