This invention describes a computer program that builds a profile for a user by tracking the webpages they visit. It collects the web addresses, then downloads and examines the content on each page. The program analyzes different types of content, including using Natural Language Processing for text, to find important keywords and assign them an "affinity value" indicating the user's interest. These keywords and their affinity values then form the user's unique profile.
Why it matters: Filed before the widespread adoption of advanced large language models. The content analysis and keyword identification, which required significant custom algorithm development in 2020, can now leverage more powerful and accessible AI tools.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
