When it comes to common searches that repeat millions of times like “Britney Spears” or “Hybrid Cars,” returning the most appropriate results, or advertisements, is not difficult. But what about queries that are exceptionally rare and may never repeat more than a single time? Clearly, these queries are infinitely harder for the search engine to understand.

Andrei Broder, Yahoo! Research Fellow and Vice President of Search Technology and Computational Advertising, and a team of Yahoo! researchers set out to tackle this problem. Their work is outlined in a paper called Robust Classification of Rare Queries Using Web Knowledge, that appeared in SIGIR 2007.

To address the problem, the Yahoo! team proposed a methodology for using search results, as well as information available on the Web, as a source of external knowledge. To this end, they sent rare queries to a search engine and assumed that a majority of the highest-ranking search results were relevant to the query. Categorizing these results allowed the team to classify the original query with high accuracy.

The results definitively confirmed that using the Web as a repository of world knowledge contributes valuable information about the query, and aids in its correct classification. “We discovered the best source of information to understand what these rare queries are about is to look at the search results,” Broder explains. “If you look at each returned page as a vote on what the query is about, you find that the majority tends to be correct even though many individual pages are wrong.”

“Notably great experiences are punctuated by a moment of ‘wow,’ when the product or service delights, anticipates the needs of, or pleasantly surprises a customer. OXO’s Good Grips Angled Measuring Cup triggers such a moment of wow. A set of angled markings on the OXO cup lets you quickly measure liquids for recipes without having to stop cooking and bend over. Suddenly a little part of your life is easier, because OXO thought carefully about the way you cook. This delightful surprise resonates because it feels tailored to your needs.”

“In traditional marketing research, she says, if you ask what the main constraints on usage of communication services are, the obvious answer would probably be price and some personal attitudes towards tech. But what we find in our research, observing people closely, is that actually the real discriminants are time and social networks.

Time: we collect hundreds of timelines and logs, we ask people to reconstruct with us their previous day of communication: who they communicated with, how, etc. We ask them to describe their social environment. Let’s consider teenagers. The image adults have about teenagers online is lots of friends, connected all the time, etc. Swiss teenagers: all use instant messaging; e-mail is used only for communicating with adults and institutions; all of them have a mobile phone and send SMS daily; more than 50% have a profile page on social networking sites; they read blogs and use Youtube etc. BUT there is something very specific to the Swiss educational system. In Switzerland, there is a high proportion — 75% — of professional/vocational training (”apprentices”). Teenagers are in a professional setting; receive a salary; they are in constant contact with adults during the day; etc. If we compare the structure of the day of the teen apprentices and that of their parents, it’s often not that dissimilar, except for the evening hours. And their patterns of communication are also very similar: balancing between work and private life; have a rather limited set of contacts. Apart from instant messaging, in Switzerland from 13 to 50 year old the patterns of usage of communication channels are very similar.

The other factor that has an impact on communication behavior is social networks. The close circle of contacts is composed of about 20 people: 7 in the “intimate circle”, 13 in the “close circle”. A further 37 are “weaker ties”. This core of 20 is a number that’s consistent across countries in Europe and the US. Who’s in this core? About 60% are “given” contacts (family, schoolmates, work colleagues, neighbours), only 40% are “chosen”. If you look with whom people communicate, 3/4 of the contacts happen with the people within those 20 “core” contacts. What does this mean? It may look obvious, you only communicate with the people you know. But to me it means: those 20 people are our (telecom operator’s) playing field. When we think of services for our customers, we have to keep in mind that their space is 20 people wide.”

The conference LIFT08 will take place for the third time in Geneva, Switzerland, on 6-8 February 2008. The main structure of the programme has been presented tonight in a trendy bar downtown Geneva by organizer Laurent Haug and editorial producer Nicolas Nova.

And again, like last year, they seem to have got a knack of seeking out many new voices and speakers that haven’t made the rounds yet – but have interesting things to say. The programme is structured in thematic “tracks”, four per day on Thursday 7 and Friday 8. On Wednesday, a pre-conference will present a series of focused workshops. Thursday evening will feature the now-traditional fondue for 500+ people. Alongside the main conference there will be a “blogcamp”-like space for unplanned discussions and presentations, as well as an “off” space dedicated to design, art and games.

Here a quick rundown of the main tracks:

• Internet in society — With Jyri Engestrom (he just sold microblogging platform Jaiku to Google), Jonathan Cabiria (on virtual environments and social inclusions) and others
• User experience — With two tech anthropologists, Younghee Jung (Nokia, Tokyo) and Genevieve Bell (Intel, Seattle) and UC’s Paul Dourish.
• Stories — With serial entrepreneur Rafi Haladjian and others.
• A glimpse of Asia — With Marc Laperrouza, a specialist of new tech in China, Heewon Kim, a Korean researcher on teens and social networks, and others.
• New Frontiers — With “cyborg” Kevin Warwick, Henry Markram who’s trying to simulate the functioning of brain cells, and Holm Friebe talking about new forms of cooperation and collaborative work.
• Gaming — With Robin Hunicke (who worked on games for the Nintendo Wii) on gaming trends, and others.
• Web and entreprises — With David Sadigh and David Marcus on how the web is reshuffling work practices.
• Foresight — With future researchers Scott Smith (Changeist) and William Cockayne (Stanford) and Nokia designer Francesco Cara.

Haug also announced that LIFT is exporting itself to Asia: after a successful small launch event a few weeks ago in Seoul, South Korea, they’re now planning a full LIFTAsia in September 2008, again in Seoul.

I am very pleased to notice that Genevieve Bell, Paul Dourish and Francesco Cara are amongst the speakers.

“Of all the ways Apple’s iPhone is disrupting the mobile-phone industry, one of the most tangible is in how it’s shaking up the user experience. The release of the music-playing mobile phone brought many people a whole new way to call up services, navigate from one section to another—even dial a phone number. Apple may raise the bar further in January, when it’s expected to make it easier for outside developers to create tools and features for the iPhone.

Competing makers of smartphones—wireless handsets that double as mini computers—have gotten the message. And in the wake of the iPhone launch, many are taking pains to improve their own software and hardware to eliminate the often arduous or non-intuitive task of gaining access to even the most basic information.”

Unfortunately, the article confuses usability and user experience with “adding bells and whistles to cell phones” or feature richness, which they think will make the phone more expensive.

The selected sites also cover themes such as accessibility, web standards, and interfacing.

I am pleased to say that this blog is also included in the list.

As it is being tested, only some users get to see the new navigation and UI right now. However, Amazon have a “remodel” page (UK version) where they go through the changes and display a screenshot.

They seem to have done extensive usability testing based on a user-centred design approach:

We consulted the foremost experts in the field: our customers.

We traveled around the world, inviting customers like you to come and try out the new features and design. We listened to their feedback and made changes based on their opinions. Then we asked more customers for their advice, and we made more changes from their feedback. The design you see today reflects the input of many real-life customers of our U.S. and international websites.

We concentrated on shopping, searching, saving, and buying–the four activities that customers have repeatedly told us are the most important to them. They’re now prominently featured at the top of every page on the site.

“Only a few years ago, human factors was a discipline virtually ignored in the medical device world. Device design was a field dominated by engineers, and their main concern was whether the device functioned properly or not. How easy it was to use, how well it fit into a caregiver’s workflow, and whether the design contained the potential to prompt use errors were factors considered secondarily, if at all.

But that is changing. More device companies are incorporating principles of human factors and ergonomics into their designs. Some are hiring human factors experts for their staffs, while others are using consultants. More devices go through some form of usability testing before hitting the market. And FDA has begun refusing to accept “it was a user error, not a design problem” as an excuse for problems in the field. […]

What follows is a look at some of the trends that are forcing medical device manufacturers to change their design practices, and should force those who haven’t to reconsider.”

Paul Rouke has posted a long user experience review “looking at how persuasion architecture has been adopted, key browsing functionality provided and the overall shopping experience you can expect at this new luxury online store”. He calls it a “user experience triumph“.

Putting brands at what appears to be the forefront of their online strategy, the new House of Fraser website provides an almost immediate synergy between their online experience and the aspirations of the brand hungry visitor. On first view the site provides all the features and functionality you would expect from a site which has been developed using what I expect would have been a user centered design approach - high visibility of the search functionality and shopping basket (inc. summary of key info, a useful mini basket dropdown feature and the login/register links), clearly labeled and intuitive category navigation, a clear, best practice modeled checkout process and a strong focus on persuasion architecture.

He concludes:

Irrespective of the possible user experience improvements that could be introduced, House of Fraser have produced an excellent e-commerce website which perfectly suits its target audience and compliments its high street presence. With a degree of richer user experience functionality introduced, and a clear focus on branding and imagery, whilst adopting very much a user centered design approach and significant persuasion architecture techniques, House of Fraser’s first transactional web presence is destined to be a great success and very much a destination website for style and brand driven online shoppers.
