URL Sanitization

For URLs with query strings, the code aims to remove query parameters unrelated to content navigation. It does so by iteratively removing each query parameter and testing the resulting content for differences with original content. The code also remove query parameters often related to user PII by using simple string matching.

Requirement

The URL Sanitization requires Python 3, along with the pandas, numpy, urllib, difflib, pebble, BeautifulSoup, and phonenumbers modules.

How it works

The function process_urls() takes a list of URLs from url_training_data_path and for each domain, generates a rule that determines which query parameters will be removed. Then, it applies the rule to the data in url_full_data_path and removes URL parameters that do not meaningfully change page content. Then it saves cleaned URLs to the output_data_path.

The script requires tab-separated values (TSV) files and outputs the same (URLs may contains commas). The URLs to be processed must be called canonical_url in the input data url_training_data_path and output data url_full_data_path.

Examples

The file demo_run.py illustrate an example. The file demo_input.tsv illustrates how the prepare the to-be-cleaned URLs data (both the training data and the full data). The file demo_output.tsv illustrates the expected processed results.
