Dataset Card for CrediBench 1.1

CrediBench 1.1 is a large-scale, temporal webgraph constituted of web data pulled from Common Crawl. A prior version of the paper is available here (NPGML workshop @ NeurIPS 2025), with the latest version still under review. CrediBench 1.0, presented in this prior work, constituted of a static webgraph with 1 month's data, while the current version contains 3 months of data (October to December 2024, surrounding the U.S Federal elections, a period of increased misinformation). We are actively constructing and uploading more monthly graphs as well.

Dataset Details

Dataset Description

This dataset is composed of monthly slices of large-scale web networks. These webgraphs contain 1+ billion edges, and 45+ million nodes per month. In these webgraphs, the nodes represent a website domain (e.g, google.com) and an edge represents a directed hyperlink relation (e.g, an edge from cbc.ca to reuters.com indicates that a page on cbc.ca's website contains a hyperlink to a reuters.com page). These webgraphs are supplemented with text attributes, partly from Common Crawl and from web scraping, as text features play an important role in misinformation detection. Additionally, we supplement them with credibility scores as made available by Lin et al., to enable supervised and semi-supervised learning as explained in our paper.

Resources

• Repository
• Paper
• Common Crawl is our primary data source, supplemented with web scraping and multiple datasets for credibility signals:
  • DQR for credibility scores for supervised learning, and
  • Yasin et al.'s phishing domains,
  • Potpelwar et al.'s malware domains, and
  • Aung et al.'s legitimate domains, for semi-supervised learning.

Uses

This dataset is intended as a data source for research efforts against misinformation online. Specifically, as the first large-scale, text-attributed webgraph that is also dynamic, CrediBench stands as an ideal data source for efforts to develop methods for unreliable domain detection based on spatio-temporal cues.

Out-of-Scope Use

This dataset is not intended for LLM training. Designed for the goal of misinformation detection at the domain level and web scale, this dataset contains numerous domains and content pages that contain innapropriate content which may be harmful if used for training conversational AI, or other types of generative AI outside the scope of our task.

Data Collection and Processing

The process of collection, processing and use is detailed in our team's paper. We collect data through our proposed CrediBench pipeline (available at our repository), which builds a month's worth of data by pulling from Common Crawl, builds the graph from it and processes it to discard isolated and low-degree nodes. Each edge has a timestamp, given as the date of the first day of week of the crawl, in format YYYYMMDD.
