Media Bias Taxonomy: Literature-Review

In this repo, we detail all workflows accompanying our Media Bias Taxonomy. Also, we publish an easily usable literature crawler to execute literature reviews.

Introduction

This repository contains all resources from the paper "The Media Bias Taxonomy: A Systematic Literature Review on the Forms and Automated Detection of Media Bias." Our literature review summarizes the research on computational methods to detect media bias by systematically reviewing 3140 research papers published between 2019 and 2022. The link to the paper will be added in case of journal acceptance.

Get started with our crawler

To facilitate research of media bias we share the code of the scraping tool we used to retrieve the candidate documents for our literature review. The tool uses the REST APIs of Semantic Scholar and DBLP to retrieve literature from both platforms for a set of search terms. To search Semantic Scholar, you require a Semantic Scholar API Key.

How to use the crawler

We provide the tool as a documented Jupyter Notebook:

crawler_ses-dblp.ipynb

Follow these steps to use the tool:

1. Make sure that you have the modules requests, json, pandas, numpy, tqdm, and time installed and up-to-date.
2. In the "Search Parameters" section of the scraping tool, you can adjust setting to your search preferences:
   • search_semantic_scholar and search_dblp : Where to perform the search.
   • year_range_start and year_range_start : Settings for the publication period to search for.
   • SSkey : Insert your Semantic Scholar Key here.
   • max_ses : Number of Document per keyword to be retrieved from Semantic Scholar. Use multiples of 100 (e.g., 200, 700, 1500).
   • return_fieldes : Choose, which information the tool retrieves on each publication from Semantic Scholar.
   • publication_type : Types of publications to be searched for on Semantic Scholar.
   • fields_of_Study : Select from a range of fields of study to be searched for on Semantic Scholar.
3. Preparing Keywords. Provide a keyword file named "keywords_ses.txt" for Semantic Scholar and "keywords_ses.txt" for DBLP, in which each line contains a search query. The initial keywords files in this repo are empty, so please make sure to fill them before running.

The Jupyter Nootebook provides further instructions on how to use the tool In the comments and Markdowm segments.

2. The tables

As mentioned in the paper, we publish the accompanying tables. They can be found here on Zenodo.
