Replication package: news corpus metadata and analysis code for mediatised Urban Air Mobility in China's low-altitude economy ```

Summary of the Replication PackageManuscript: “Mediatised Urban Air Mobility: discursive closure and the vertical imaginary in China's low‑altitude economy” This package supports the computational discourse analysis reported in the study. It includes: Corpus metadata – raw retrieval records (1,018 items) and the final analysed set (802 articles after relevance and length screening). Derived result tables – numerical outputs that correspond to Tables 1–3 in the paper. Analysis scripts – Python code for data collection, screening, and NMF topic modelling. Data collectionArticles were obtained via SerpApi Google News with 30 search queries (17 English, 13 Chinese), covering publications from 1 January 2018 to 1 May 2026. The retrieval was carried out on 7–8 May 2026. After exclusions, the final corpus spans from 25 December 2014 to 7 May 2026 and comes from 300 distinct outlets. What is not includedFull article texts are not redistributed due to copyright. The original content can be retrieved using the url field in the metadata. The reproduction workflow requires re‑running the collection step with a valid SerpApi key (the key is not supplied and must be set as an environment variable). ReproductionThe full three‑step workflow is documented in README.md. The environment uses Python 3.10.11; all required packages are listed in requirements.txt. LimitationText cleaning retains only ASCII characters, which may affect articles with non‑English scripts or special symbols. For any questions about accessing or reproducing the results, please refer to the metadata files and the README. The authors can provide further assistance on the screening and modelling steps upon request.
