Google’s Historical Data Ranking Factors Revisited, Plus Advertising Rankings

In March, 2005, Google published Information retrieval based on historical data and provided us with an incredible list of factors that might be used to rerank pages in search results.

It stirred a lot of discussion, and “time” became something people started thinking about in how Web pages are ranked by search engines.

Flowchart from patent application

A few domain hosting companies started recommending people register domain names for longer than one year since Google might see single year registrations as possible indications of a spammer’s site.

A “sandbox” effect, which appears to make new sites not rank well during an extended period of months, for competitive keywords rankings, was considered by some to be a result.

Google’s Presentation Patent Application (via Tonic Systems)

My friend Debra tagged me earlier today. I came up with five reasons I like to blog, last week, so I’m going to incorporate three more into this post.

I like keeping track of news regarding changes in the world of search, like the Official Google Blog reporting today that Google has acquired Tonic Systems, maker of software that can be used to create and convert presentations. The Tonic Systems Web page has a frequently asked questions section with more details.

I like conducting research, which led me to hunt down a patent application for Tonic Systems filed with the World Intellectual Property Organization, International Board – Systems, Methods and a Computer Program for Use in Manipulating Electronic Presentation Information (WO/2005/078602). The USPTO version hasn’t been published.

I like trying to understand what kinds of impacts changes like this might have. As Barry notes at Search Engine Land, this acquisition widens the scope of the online office suite that Google offers, though it won’t be a replacement for Microsoft’s offerings. It may have the potential to be as widely used – especially if the presentations can be easily shared and shown (and indexed) on the web.

Papers for Tagging and Metadata for Social Information Organization

One of the workshops at the 16th International World Wide Web Conference (WWW2007), to be held in Banff, Alberta, Canada on May 8, is a workshop on Tagging and Metadata for Social Information Organization.

As content grows on the web, generated from many different sources, annotations and tagging of that content is also happening at a tremendous rate of growth. Those tags can help people find and filter information on the web, and collaborative filtering can tell us something about the content found upon the web, and the ways that people use it.

I’ve included links to the papers here, as well as abstracts for the papers, and links to as many of the pages for the authors of those papers as I could find.

If you use digg, or or Flickr or other tagging and social networking type web sites, you may find a number of these papers interesting.

Future of Web Search Conference Videos

Last May, the Yahoo Future of Web Search Conference was held in Barcelona. Hat tip to Keri Morgret, it appears that videos of the presentations are online.

On Sunday, I posted over at Search Engine Land about the papers that have been published for AIRWeb 2007. The papers from the Third International Workshop on Adversarial Information Retrieval on the Web contain some interesting topics that are worth looking at if you are concerned about Web spam.

One of the Organizing Committee members of AIRWeb2007, Carlos Castillo of Yahoo Research, was one of the presenters at the Yahoo Future of Web Search Conference. His presentation is pretty interesting – Using Rank Propagation and Probabilistic Counting for Link-based Spam Detection.

It covers subjects such as:

Targeted Audio Advertising with Google Part 3 – Conclusion

Is Google becoming less of a search company, and more of an advertising company? These two patent applications (discussed in part 1 and part 2) cover an advertising system that include ads on television, radio, podcasts, audio and video streams, and telephones, and while most involve determining relevancy, few concern serving search results.

The Goog 411 service does provide local search on the phone, and a video search example provided also allows for search possibly along the lines of what podzinger offered. Google TV Ads and radio ads focus upon ease of advertising, determinations of relevancy, and the serving of ads, but are a move away from Google’s search background.

The patent applications do move on to cover such additional topics such as determinations of ad spots, how filters might work for ads, and revenue sharing between Google and publishers. Will this advertising model be the one that emerges from Google in serving audio ads on television, radio, internet, and the phone?

Targeted Audio Advertising with Google Part 2 – Relevancy

My last post was on examples from Google’s recent audio patent applications. Today, I’m going to take a closer look at the processes described in the patent filings. The two documents are:

Assumptions behind Google’s advertising

Interactive advertising lets advertisers target ads to a receptive audience, and the relevancy of targeted ads makes it more likely that the ads will be useful to end users. Query-based keyword targeting has been effective in delivering relevant ads, and AdSense has been an effective way of serving ads that are relevant to the content found on Web pages.
