Abstract: qta performs quantitative text analysis on ESG (Environmental, Social, and Governance) disclosure reports. The command analyzes text content to measure the extent and quality of ESG disclosure based on different text analysis methods and languages. The command generates multiple ESG disclosure metrics including dimension-specific scores, total disclosure score, disclosure quality index, diversity measure, and completeness indicator.
