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

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:Original CE definitions from academic sourcesPublication year for temporal trend analysisReference information for citation trackingDetected R-strategies (R0–R9) based on predefined keyword listsExtracted themes beyond R-strategies (e.g., economic growth, social equity, eco-innovation)The dataset supports statistical, thematic, and trend analyses of CE definitions, providing insights into integrating sustainability dimensions over time.
