CONTEXTUAL MOBILE APPLICATION ADVERTISEMENTS

摘要

Aspects of the subject disclosure are directed towards retrieving advertisements relevant to application content based upon keywords extracted from the application content. In one aspect, a client-side component scrapes application page content to obtain keywords and feature-based weights for those keywords. The keywords are sent to an advertisement server, which returns an advertisement based upon one or more of the keywords. Also described is the hashing of keywords before sending to the advertisement server to protect client privacy, and the use of a Bloom filter to avoid sending keywords to the advertisement server that do not correspond to (e.g., popular) advertisement keywords.
