[proposals] Interest Based Advertising with the Topics API (#4)

jkarlin has just created a new issue for https://github.com/patcg/proposals:

== Interest Based Advertising with the Topics API ==
**Problem** 
With the upcoming removal of third-party cookies on the web, key use cases that browsers want to support will need to be addressed with new APIs. One of those use cases is interest-based advertising.

Interest-based advertising (IBA) is a form of personalized advertising in which an ad is selected for the user based on interests derived from the sites that they’ve visited in the past. This is different from contextual advertising, which is based solely on the interests derived from the current site being viewed (and advertised on). One of IBA’s benefits is that it allows sites that are useful to the user, but perhaps could not be easily monetized via contextual advertising, to display more relevant ads to the user than they otherwise could, helping to fund the sites that the user visits.

**Proposal Summary**
The intent of the [Topics API](https://github.com/jkarlin/topics) is to provide callers (including third-party ad-tech or advertising providers on the page that run script) with coarse-grained advertising topics that the page visitor might currently be interested in. These topics will supplement the contextual signals from the current page and can be combined to help find an appropriate advertisement for the visitor.

The topics are selected from an advertising taxonomy. The initial taxonomy (proposed for experimentation) will include somewhere between a few hundred and a few thousand topics and will attempt to exclude sensitive topics. The eventual goal is for the taxonomy to be sourced from an external party that incorporates feedback and ideas from across the industry.

The topics will be inferred by the browser. The browser will leverage a classifier model to map site hostnames to topics. The classifier weights will be public, perhaps built by an external partner, and will improve over time. The browser will share up to 1 frequently visited topic (by the user) from each of the past 3 weeks to share with callers on a given site.
