Dataset of 500 circular economy definitions with extracted themes within and beyond R-strategies using rule-based NLP

DATASET MIGRATED FROM FIGSHARE: <p dir="ltr">This dataset comprises 500 peer-reviewed circular economy (CE) definitions, annotated with extracted themes within and beyond the R-strategies (R0–R9) using a rule-based Natural Language Processing (NLP) model. Each definition is accompanied by its publication year and reference source, enabling temporal analysis of CE conceptual evolution. The dataset includes:</p><p dir="ltr">Original CE definitions from academic sources<br>Publication year for temporal trend analysis</p><p dir="ltr">Reference information for citation tracking<br>Detected R-strategies (R0–R9) based on predefined keyword lists</p><p dir="ltr">Extracted themes beyond R-strategies (e.g., economic growth, social equity, eco-innovation)</p><p dir="ltr">The dataset supports statistical, thematic, and trend analyses of CE definitions, providing insights into integrating sustainability dimensions over time. </p><p><br></p>
