Hyperlinks Dataset

This dataset contains subpage links, their features, and corresponding search engine rankings from Google and Bing. The data was collected as part of the research project: "Accessible Hyperlinks and Search Engine Rankings: An Empirical Investigation".

Dataset Description

This dataset is designed to facilitate research on the relationship between website accessibility, specifically hyperlink accessibility, and search engine rankings. It consists of subpage links extracted from various websites, along with their associated features and ranking positions on Google and Bing SERPs.

Data Sources

The dataset was constructed using the following sources and processes:

  1. Trending Keywords: Initial keywords were obtained from Google Trends ("Shopping" category) over a 7-day period. These keywords are provided in raw/keywords/trending_US_7d_20141203-1845.csv.
  2. Google SERPs: The top 5 Search Engine Results Pages (SERPs) for each trending keyword were collected from Google.
  3. Website Extraction: Unique websites were extracted from the collected Google SERPs, forming the basis for further data collection.
  4. Website Scraping: Each website from processed/websites.csv was scraped to collect all of its subpage links and their features. These are stored in processed/links.csv.
  5. Subpage Link Collection from Search Engines: The site: operator was used on both Google and Bing to collect subpages associated with each website. Results are in processed/google.csv and processed/bing.csv.
  6. Matching and Labeling: Subpage links from the website scraping step were matched with the search engine results and labeled with their corresponding ranking positions (Google and Bing). This labeled data is stored in processed/labeled_links.csv.
  7. Dataset Balancing: Balanced datasets were created based on position numbers (grouped into pages) and the presence or absence of position numbers. These are in the datasets/ directory.
  8. Feature Extraction: Accessibility and other relevant features were extracted from the labeled datasets. The extracted features are stored in the extracted/ directory.

processed/labeled_links.csv:

  • This file contains the same features as links.csv plus:
  • google_position: The ranking position of the link on Google SERPs.
  • bing_position: The ranking position of the link on Bing SERPs.

datasets/ (Balanced datasets with raw features):

  • The balanced datasets in this folder contain a subset of the raw features from labeled_links.csv. The exact features included may vary depending on the specific balancing criteria used. Refer to the Data Collection and Processing repository for details.

extracted/ (Extracted Accessibility Features):

  • label: The class label derived from the search engine ranking position. (e.g., page number of the link on SERPs).
  • has_text: Whether the link has innerText, title, ariaLabeledText.
  • has_html: Whether the link has innerHTML.
  • is_visual: Whether the link is visually rendered (same as in links.csv).
  • is_bold: Whether the link text is bold.
  • is_underlined: Whether the link text is underlined (same as in links.csv).
