piedomains: predict the kind of content hosted by a domain based on domain name and content

The package infers the kind of content hosted by a domain using the domain name, the textual content, and the screenshot of the homepage.

We use domain category labels from Shallalist and build our own training dataset by scraping and taking screenshots of the homepage. The final dataset used to train the model is posted on the Harvard Dataverse. Python notebooks used to build the models can be found here and the model files can be found here

Installation

We strongly recommend installing piedomains inside a Python virtual environment (see venv documentation)

pip install piedomains

General API

1. domain.pred_shalla_cat_with_text(input)

• What it does:

• Predicts the kind of content hosted by a domain based on the domain name and the HTML of the homepage.
• The function can use locally stored HTML files or fetch fresh HTML files.
• If you specify a local folder, the function will look for HTML files corresponding to the domain.
• The HTML files must be stored as domainname.html.
• The function returns a pandas dataframe with predicted labels and corresponding probabilities.

• Inputs:

• `input`: list of domains. Either input or html_path must be specified.
• `html_path`: path to the folder where the HTMLs are stored. Either input or html_path must be specified.
• `latest`: use the latest model. The default is True.
• Note: The function will by default look for a html folder on the same level as model files.

• Output:

• Returns a pandas dataframe with the predicted labels and probabilities

• Sample usage: :

  from piedomains import domain
  domains = [
      "forbes.com",
      "xvideos.com",
      "last.fm",
      "facebook.com",
      "bellesa.co",
      "marketwatch.com"
  ]
  # with only domains
  result = domain.pred_shalla_cat_with_text(domains)
  # with html path where htmls are stored (offline mode)
  result = domain.pred_shalla_cat_with_text(html_path="path/to/htmls")
  # with domains and html path, html_path will be used to store htmls
  result = domain.pred_shalla_cat_with_text(domains, html_path="path/to/htmls")
  print(result)

• Sample output: :

  domain  text_label  text_prob  \

2. domain.pred_shalla_cat_with_images(input)

• What it does:

• Predicts the kind of content hosted by a domain based on screenshot of the homepage.
• The function can use locally stored screenshots files or fetch fresh screenshots of the homepage.
• If you specify a local folder, the function will look for jpegs corresponding to the domain.
• The screenshots must be stored as domainname.jpg.
• The function returns a pandas dataframe with label and corresponding probabilities.

• Inputs:

• `input`: list of domains. Either input or image_path must be specified.
• `image_path`: path to the folder where the screenshots are stored. Either input or image_path must be specified.
• `latest`: use the latest model. Default is True.
• Note: The function will by default look for a images` folder on the same level as model files.

• Output:

• Returns panda dataframe with label and probabilities

• Sample usage: :

  from piedomains import domain
  domains = [
      "forbes.com",
      "xvideos.com",
      "last.fm",
      "facebook.com",
      "bellesa.co",
      "marketwatch.com"
  ]
  # with only domains
  result = domain.pred_shalla_cat_with_images(domains)
  # with image path where images are stored (offline mode)
  result = domain.pred_shalla_cat_with_images(image_path="path/to/images")
  # with domains and image path, image_path will be used to store images
  result = domain.pred_shalla_cat_with_images(domains, image_path="path/to/images")
  print(result)

• Sample output: :
