Bill Slawski on Google patents for ratings and raters
I've been following Bill Slawski's SEO by the Sea for a few years. I enjoy the presentation of search related patents and trends and the exposition of technology used by the big names in the search industry: Google, Yahoo! and Microsoft. Due to my recent intereset in recommendation systems (I now work at Outbrain) I searched back for Bill's posts on recommendation systems, ratings and raters. I came up with quite a lot:
- Google Approach to Making Online Ratings Easier... (on October 2, 2009)
- Innovating Product Reviews at Google (on June 16, 2006)
- The Growing Power of Online Reviews (on September 6, 2006)
- Google Reviews: Reputation + Quality + Snippets + Clustering (on April 6, 2007)
- Google's New Review Search Option and Sentiment Analysis (on June 12, 2009)
- How Google May Rate Raters (on June 15, 2009)
I wrote two comments on that post:

I wonder why not just use the actualaccess to a page through Google as a way to measure popularity — in a way, a Click Through Rate measure — number of actual clicks on the proposed page (link) by google on screen divided by the number of times it was shown

Apparently, if a user actually clicks the link of a search result, then it means that there’s some sort of agreement with it. In cases where google can “see” (cookie of a google domain or of an affiliate) the page view timing or other clue of user satisfaction from the actual “landing” on the page, then it is an additional indication of satisfaction. So, perhaps raters are not so good and they are biased and not representative?!
- Opinion Summaries in Google Maps Reviews (on August 4, 2009)
While Google is in the search business and advertisements, Outbrain attempts to make its living from promoting content. The readers that get the recommendations come first -- they are offered with the highest quality recommendations, the revenue comes next. It makes sense as in the long run, the more satisfied the readers are the more they click on the recommendations. So, as long as the recommendations are of high quality, the traffic will drive profit, instead of doing it backwards (by attempting to influence and to control traffic with short term revenues as motivation).

לעז -- מילות שירים לועזיים בתרגום חופשי לעברית

יוצאי הדופן והכללים בגזירה ובנטייה

The teacher claimed it was so plain,
I only had to use my brain
She said the past of throw was threw.
The past of grow -of course- was grew,
So flew must be the past of fly,
And now, my boy, your turn to try.
But when I trew,
I had no clue, if mow was mew -
Like know and knew
Or was it knowed
Like snow and snowed
The teacher frowned at me and said
The past of feed was – plainly – fed.
Fed up, I knew then what I ned:
I took a break, and out I snoke.
She shook and quook (or quaked or quoke?)
With raging anger out she broke:
"Your ignorance you want to hide?
Tell me the past form of collide!"
But how on earth should I decide
If it's collid (Like hide and hid)
Or else – from all that I surmose,
The past of rise was simple rose,
And that of ride was surely rode
So of collide must be collode?
Oh damn these English verbs, I thought
The whole thing absolutely stought !
Of English I have had enough.
These verbs of yours are far too tough.
Bolt upright in my chair I sat,
And said to her "That's that. I quat!".
כשיש עננים אומרים – היום מעונן.
וכשיורד גשם אומרים – היום מגושם?
-מה פתאום?!
כשיורד גשם אומרים – היום גשום.
למה?
-ככה זה בעברית.
מי שמתלבש הוא לבוש.
ומי שמתפשט הוא פשוט?
-מה פתאום?!
מי שמתפשט הוא ערום.
למה?
-ככה זה בעברית.
מי שמתרחץ הוא רחוץ.
ומי שמתנגב הוא נגוב?
-מה פתאום?!
מי שמתנגב הוא מנוגב.
-למה?
-ככה זה בעברית.
אם אומרים – הרבה חורים וחור אחר,
למה לא אומרים – הרבה הורים והור אחד?
ואם אומרים – חור אחר והרבה חורים,
למה לא אומרים – אור אחד והרבה אורים?
-למה? ככה זה בעברית.

הקנון המדעי מאת נטלי אנג'יר

"חלל פנימי, חלל חיצוני, קנה מידה גלקטי, קנה מידה אטומי
-- היינו הך, אין ואפס. אנחנו חיים ביקום נטול חומר רובו ככולו. ובכל זאת שביל החלב
זוהר, ובכל זאת ההמוגלובין זורם בדמנו, וכשאנו מחבקים את אהובי נפשנו, אצבעותינו
אינן שוקעות בריק הממלא את כל האטומים. אם הנגיעה בעורם היא נגיעה באין, מדוע
התחושה כל כך מלאה?"
A view of Outbrain's algorithms' focus

There's a post at the Outbrain blog, What do readers really want?, which reasons why contextual relations among documents is not necessarily the most interesting content for readers when being recommended for additional content. Apparently, the related contextual related content is less appealying to readers than the behavioral related content.
* Popularity: recommending content that is trending up in popularity on the site
* Contextual: recommending content related to the page the person is currently on
* Behavioral: recommending content based on audience dynamics. For instance, finding content that people with similar reading habits have been consuming, that is not mainstream popular, and that the person has not read before
* Personal: recommending content within broad categories that the person frequents but not necessarily related to the page they are on at present
When evaluating success, we look at a couple of metrics.
1. How frequently do people click on links based on the algorithmic approach (CTR, or “click through rate”)
2. How many more pieces of content does the person consume on the site *after* clicking on the link (what we call PVAC, or “pageviews after the click”)
Check out that post: What do readers really want? by David Sasson.
