This replication package constructs the results for the paper titled News-sharing as a measure of media alignment by Gabor Simonovits and Adam Vig, published in the Journal of Quantitative Description: Digital Media. A Makefile runs all of the code to clean and organize the data and generates the tables and figures in the paper. The replicator should expect the code to run for about 2-3 minutes.

• All data are publicly available.
• Some data cannot be made publicly available.
• No data can be made publicly available.

The data were collected by the authors, and are available under a Creative Commons Non-commercial license.

• Database of citations on 24.hu and origo.hu data/raw/newspaper_citations_data_raw.csv were collected using scraping code writen in Python by the authors. Scraper code is available at the code/scraper folder.

• Validation data on the slant of Hungarian news portals data/validation/hungarian_media_slant.csv is from Bátorfy (2020).

• Readership data for Hungarian domains There is a .csv or .xlsx file in the data/raw/gemius/ folder named as gemius_YEAR_MONTH for each consecutive month which contains the number of real user for Hungarian domains estimated by Gemius (2022).

The following versions of Python, R and GNU Make were used by the authors:

• Python 3.10.0
• R 4.1.2
• GNU Make 3.81

Package requirements are stored in the Pipfile.lock and renv.lock files. pipenv is used for Python, renv for R dependency management. CNU Make for execution.

Note: requirements for scraping the citations database is listed in requirements.txt in the code/scraper folder.

A few minutes needed to reproduce the analyses on a standard 2023 desktop machine. The authors would not recommend running the scraper code on a destop machine.

The analysis code were last run on a 8-core M1 Macbook Pro with 16 GB RAM and MacOS version 13.2.

The scraper code were last run on a 8-core AWS EC2 server with 32 GB of RAM.

• Scraper

There is no master script for the scraper code. The scripts scrape-24hu-sitemaps.py and scrape-origo-archive.py collect the urls for every published article at 24.hu or origo.hu respectively. 24hu_parser.py and origo_parser.py contain parser functions for the sites. The functions parse the html script of one article published on 24.hu or origo.hu respectively. The scraper codes were last executed on 2022.08.02.

Note: The parser functions might need modification to work properly, as the sites might change their HTML content since our last execution.

• Analysis

1. run make install in terminal to set up the environment and required folders for the analysis.
2. run make in terminal to clean and organize data and replicate the 7 figures and 3 tables used in the paper.

• Scripts in code/scraper can be used to replicate the raw data used by the analysis.
• code/activate_renv.R is run by make install and activates the virtual environment for R.
• Scripts in code/data-processing/
  • clean and reformat the scraped citation database data/raw/newspaper_citations_data_raw.csv.
  • clean and concatenate the montly datafiles of real usership in data/raw/gemius/.
• Scripts in code/figures generate all figures in the main body and the appendix of the article.
• Scripts in code/tables generate all tables in the appendix of the article.

The provided code reproduces:

• All numbers provided in text in the paper
• All tables and figures in the paper

The output files are named after their corresponding script and are in results/figures or results/tables.
