USPTO App: Content Based Advertising Using Collaborative Filtering (0070100813)
United States Patent Application: 0070100813
The first of three major inventions I made and patented while at Yahoo! Research. This was the original start of the series, and was trigger through discussions internally with Deepa Joshi.
All three are based on a form of collaborative filtering of search results, using modified search engine similarity metrics, and the same’s inverted index techniques for performance. This one deals with assigning keywords to new webpages, to provide content-based advertising. One way to assign meaning to a page is to count the search referral keywords. This is great, if the page is popular and in the index. If it isnt, this technique allows to assign keywords based on the keywords similar pages have created.
