Interactive Shiny Application for Quallmer Validation

Overview

quallmer.app provides an interactive Shiny application for working with qualitative data coded using the quallmer package. The app supports:

• Manual coding: Code qualitative data directly in an intuitive interface
• Review LLM-generated coding: Examine and validate AI-produced annotations
• Compute agreement metrics: Calculate inter-rater reliability and validate against gold standards

pak::pak("quallmer/quallmer.app")

Usage

library(quallmer.app)

# Launch the quallmer app

# Get the path to the sample data file
sample_file <- system.file("extdata", "sample_data.rds", package = "quallmer.app")

# Launch the app
qlm_app()

# In the app, upload the file at the path shown by:
print(sample_file)

The sample dataset contains 20 movie reviews coded by three coders with a gold standard, perfect for testing inter-rater reliability and gold-standard validation features.
