For far too long computer science has directed the development of search systems. This is
problematic from an experience point of view because computer science measures success by
different standards than we do. It is no wonder then that search systems have developed with
minimal attention to the user experience beyond the assumed perfection of results relevance and
the appropriate ad-matching. The intent of this plenary is to inspire us all to engage on a deeper
level in designing search experiences that do more than sell products well.

Too much information
Hosted Websites
•July 1993: 1,776,000
•July 2005: 353,084,187
Individual Web pages
•1997: 200 million Web pages
•2005: 11.5 billion pages – now likely well over 12 billion
•2009: Google announces that its spiders have found 1 trillion URLs found and the Google index is at 100+billion pages
No Silver Bullet Solution
•Language and perception are different
•Some people think women put their stuff in a purse, others a pocketbook, and others a handbag.
•“Animal” is a form of mammal, a Sesame Street character, and an uncouth person
•Over 140 calculations are now used for PageRank valuation and still “gets it wrong a good percentage of the time
•Customers are looking because they don’t know
•Customers no longer know how to construct successful queries
•Search engine intent Is not always “finding the most relevant information”
Cost of finding information according to an IDC April 2006 report = $5.3 million for every 1000 workers

Woody Allen says that 80% of success is showing up. That is how it works with search engines
also; you have to show up in the index to show up in the results. Here are two screen captures
from my Agency’s website. The one in the upper left is what our customers see. The one in the
lower right is what the search engines “sees.” So, someone using a search engine to find my
agency will not do so because all the spider “sees” is a big black hole.
If you want your customers to find the websites that you design and the interactions and
experiences contained there using search technology, you must have text on the page.
A prophet is not taken seriously in “her” own land.

Michael Wesch, Kansas State University, has done a masterful job of looking at the many ways in
which digital text is different from print/spoken/filmed text. So, why do we keep treating it as if it
were the same?
If Tim Berners Lee knew where we would be now, he would not have used HTTP as a foundation
for the Web but he did and we’re stuck with it. Since then, we’ve been trying to design around
the limitations without success. Search systems are founded in text. Their capability to index
visual mediums is growing but is based on translation into text.
It is, and will remain so for the foreseeable future, all about text. The maturation of the Semantic
Web will further enhance the importance of content on the page and meaning off the page.

The search engines are like people who keep buying bigger clothes to hide their weight game.
Soon the client must come as it has somewhat with Google that starts with whether or not the
page is index-worthy.
Google Caffeine: new infrastructure opened to developer testing in public beta (August 2009):
Even cheap infrastructure has its cost limits and Google looks to reaching its limit with regard to
retention of what it is finding out there, likely a lot of “Web junk” doesn’t even make the cut.
Google Caffeine is:
•Faster
•More keyword string based relevance
•Real time indexing – breaking news
•Index volume
Currently, the determination is done by computational math. Who should decide what goes and
stays? Us! We can influence the search engine’s behavior by getting rid of the “set it and forget
it” method of Web publishing. Keep content fresh and current. Check every now and then.
Publish deep, rich context-rich content and tend to it. Not all of it, the most important pieces. Not
all content is created equal.

Here it is, the famous, to some infamous PageRank algorithm. This is its most stripped down
state. Rumor has it that the algorithm now has in excess of 27 components. We’ll look at some of
these extensions in a few moments.
Important to note: The PageRank algorithm is a pre-query calculation. It is a value that is assigned
as a result of the search engine’s indexing of the entire Web and the associated value has no
relationship to the user’s information need. There have been a number of additions and
enhancements to lend some contextual credence to the relevance ranking of the results.
When Google appears in 1998, it is the underdog to search giants like Alta Vista and Yahoo! Its
simplified relevance model with the foundation of human mediation through linking [each link
was at that time the product of direct human endeavor and so viewed as a “vote” for the page or
site relevance and information merit]. It is not so much the underdog now with 64.6% of all U.S.
searches (that would be 13.9 billion searches in August 2009- That would be nearly 420 million
searches per day in the U.S. alone)
There are only so many slots in the golden top 10 search results for any query. Am I the only one
who is concerned with the consolidation of so much power in a single entity and is it perceived
power, something we can do something about, or actual power, something that we must learn to
live with?

Hilltop was one of the first to introduce the concept of machine-mediated “authority” to combat
the human manipulation of results for commercial gain (using link blast services, viral distribution
of misleading links. It is used by all of the search engines in some way, shape or form.
Hilltop is:
•Performed on a small subset of the corpus that best represents nature of the whole
•Pages are ranked according to the number of non-affiliated “experts” point to it – i.e. not in the
same site or directory
•Affiliation is transitive [if A=B and B=C then A=C]
The beauty of Hilltop is that unlike PageRank, it is query-specific and reinforces the relationship
between the authority and the user’s query. You don’t have to be big or have a thousand links
from auto parts sites to be an “authority.” Google’s 2003 Florida update, rumored to contain
Hilltop reasoning, resulted in a lot of sites with extraneous links fall from their previously lofty
placements as a result.
Google artificially inflates the placement of results from Wikipedia because it perceives Wikipedia
as an authoritative resources due to social mediation and commercial agnosticism. Wikipedia is
not infallible. However, someone finding it in the “most relevant” top results will certainly see it
as so.

Most SEOs hate keywords. I say that they are like Jessica Rabbit in “Who Framed Roger
Rabbit”…not bad, just drawn that way.
Keywords were the object of much abuse in the early part of the Web and almost totally
discounted by the search engines. With the emerging Semantic Web that strengthens the topic-
sensitive nature of relevance calculation combined with the technology’s ability to successfully
compare two content items for context, keywords might make more sense. In any event, they do
more good than harm. So, I advise my clients to have 2-4 key concepts from the page represented
here. The caveat is that it be from the page.
Topic-Sensitive PageRank
Computes PR based on a set of representational topics [augments PR with content analysis]
Topic derived from the Open Source directory
Uses a set of ranking vectors: Pre-query selection of topics + at-query comparison of the similarity
of query to topics

Search 2.0 is the “wisdom of crowds”
Now we help each other find things. Online this takes the form of online bookmarking and community
sites like Technorati (social sharing)
Delicious (social bookmarking) and Twitter (micro-blogging) among others. Search engines are now
leveraging these forums as well as their own extensive data collection to calculate relevance. Some
believe that social media will replace search. How can your friends and followers beat a 100 billion
page index? What if they don’t know?
11

If machines are methodical, as we’ve seen, and people are emotional, as we experience, where is the
middle ground? Are we working harder to really find what we need or just taking what we get and
calling it what we wanted in the first place?

Developed by a computer science student, this algorithm was the subject of an intense bidding
war between Google and Microsoft that Google one. The student, Ori Alon, went to work for
Google in April 2006 and has not been heard from since. There is no contemporary information
on the algorithm or it’s developer.

There is no such thing as “advanced search” longer. We’re all lulled into the false sense that the
search engine is smarter than us. Now the search engines present a mesmerizing array of choices
distracting from the original intent of the search.

No one really reads the terms of use agreements that they sign and certainly don’t keep up with
changes in this agreement over time.

Some observers claim that Google is now running on as many as a million Linux servers. At the very least, it is
running on hundreds of thousands. When you consider that the application Google delivers is instant access to
documents and services available from, by last count, more than 81 million independent web servers, we're
starting to understand how true it is, as Sun Microsystems co-founder John Gage famously said back in 1984,
that "the network is the computer." It took over 20 years for the rest of the industry to realize that vision, but
we're finally there. ...
First, privacy. Collective intelligence requires the storage of enormous amounts of data. And while this data
can be used to deliver innovative applications, it can also be used to invade our privacy. The recent news
disclosures about phone records being turned over to the NSA is one example. Yahoo's recent disclosure of the
identity of a Chinese dissident to Chinese authorities is another.
The internet has enormous power to increase our freedom. It also has enormous power to limit our freedom,
to track our every move and monitor our every conversation. We must make sure that we don't trade off
freedom for convenience or security. Dave Farber, one of the fathers of the Internet, is fond of repeating the
words of Ben Franklin: "Those who give up essential liberty to purchase a little temporary safety deserve
neither, and will lose both."
Second, concentration of power. While it's easy to see the user empowerment and democratization implicit in
web 2.0, it's also easy to overlook the enormous power that is being accrued by those who've successfully
become the repository for our collective intelligence. Who owns that data? Is it ours, or does it belong to the
vendor?
If history is any guide, the democratization promised by Web 2.0 will eventually be succeeded by new
monopolies, just as the democratization promised by the personal computer led to an industry dominated by
only a few companies. Those companies will have enormous power over our lives -- and may use it for good or
ill. Already we're seeing companies claiming that Google has the ability to make or break their business by how
it adjusts its search rankings. That's just a small taste of what is to come as new power brokers rule the
information pathways that will shape our future world.

Bowman leaves Google

“Yes, it’s true that a team at Google couldn’t decide between two blues, so they’re testing 41
shades between each blue to see which one performs better. I had a recent debate over whether
a border should be 3, 4 or 5 pixels wide, and was asked to prove my case. I can’t operate in an
environment like that. I’ve grown tired of debating such minuscule design decisions. There are
more exciting design problems in this world to tackle.”
