Patent US 11,288,686

This invention teaches how one can identify user interests based upon portions of content i.e. at a finer level of granularity than known until now. Existing computer technology could identify that a user was interested in animals if he viewed a page about animals. The instant invention allows a user to select/generate/reference/isolate a portion of content, and s/he can do this without having to install additional software to his/her browser/device. Thus, we can now know if a specific user is interested in cats, and another in dogs based upon the content portions s/he chose to reference/interact with. A profile of a user's interests can be developed across a multitude of documents. This profile of the user's interests can then be leveraged for commerce such as: better, targeted, contextual advertising; developing analytics; and far superior insights into user interests can be obtained.
