Walmart’s New Search: Context Will Have To Wait

Written by Evan Schuman
September 5th, 2012

When Walmart.com announced its new search engine on August 30 and that it had already gone live, the retailer promised the ability to understand “the intent” of a shopper’s search. As a practical matter, though, the new engine simply didn’t. But “in the next couple of months,” version two of the engine will actually consider the shopper’s queries in context, according to the Walmart executive in charge of the program.

To test whether the initial engine was indeed able to factor in a shopper’s intent, we searched for Apple. Understandably, the results were about iPhones, iPads and other hardware from that company. But we then searched for Oranges, Bananas, Pears and then again asked it about Apple, hoping that it would now understand our desire for the Garden of Eden edible type of apple, which Walmart.com does indeed sell. Nope, it didn’t take the hint and continued to display mobile computers. (When we searched for “fruit,” the desired apples did materialize in the results.)

Sri Subramaniam, vice president at WalmartLabs, said that the new search engine—called Polaris—factors in many variables that the earlier engine had not. But for the type of inquiry context where the engine considers all the shopper’s questions and then changes its answers accordingly, that will have to wait for “the next couple of months.” That is when the engine will ramp up its personalization efforts, he said.

That’s understandable, but it’s not what Walmart bragged about in its announcement on August 30, which claimed that the new engine “uses semantic search technology to anticipate the intent of a shopper’s search to deliver highly relevant results for them” and that it “focuses on engagement understanding, which takes into account how a user is behaving with the site to surface the best results for them.”

Right now, the context Polaris uses is based on the fact that the shopper is visiting Walmart.com. Using the apple example, he said, Walmart sells far more iPhones and iPads than whole, sliced or canned apples. As such, it’s reasonable to assume that a Walmart.com visitor’s apple search is for purposes of mobile, not meal.

In short, Walmart instructs its engine to first look at sales reports and to then factor product popularity into its analysis of what answer the user probably is seeking.

Specifically, Polaris decides what results to display based on product popularity (“last seven days of sales and last one year of sales”), the number of shoppers who have clicked or purchased that product, product user-generated ratings, the number of Facebook likes, what searches are popular from specific IP address ranges (suggesting geography) and other factors, Subramaniam said. “There are about 100 signals we use, not just text,” he said. That click analysis is updated every few hours.

Why Did Gonzales Hackers Like European Cards So Much Better?

I am still unclear about the core point here-- why higher value of European cards. Supply and demand, yes, makes sense. But the fact that the cards were chip and pin (EMV) should make them less valuable because that demonstrably reduces the ability to use them fraudulently. Did the author mean that the chip and pin cards could be used in a country where EMV is not implemented--the US--and this mis-match make it easier to us them since the issuing banks may not have as robust anti-fraud controls as non-EMV banks because they assumed EMV would do the fraud prevention for them Read more...
Two possible reasons that I can think of and have seen in the past - 1) Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code. 2) Also, in offline chip countries the card determines whether or not a transaction is approved, not the issuer. In my experience, European issuers haven't developed the same checks on authorization requests as US issuers. So, these cards might be more valuable because they are more likely to get approved.

A smart card slot in terminals doesn't mean there is a reader or that the reader is activated. Then, activated reader or not, the U.S. processors don't have apps certified or ready to load into those terminals to accept and process smart card transactions just yet. Don't get your card(t) before the terminal (horse). Read more...
The marketplace does speak. More fraud capacity translates to higher value for the stolen data. Because nearly 100% of all US transactions are authorized online in real time, we have less fraud regardless of whether the card is Magstripe only or chip and PIn. Hence, $10 prices for US cards vs $25 for the European counterparts. Read more...
@David True. The European cards have both an EMV chip AND a mag stripe. Europeans may generally use the chip for their transactions, but the insecure stripe remains vulnerable to skimming, whether it be from a false front on an ATM or a dishonest waiter with a handheld skimmer. If their stripe is skimmed, the track data can still be cloned and used fraudulently in the United States. If European banks only detect fraud from 9-5 GMT, that might explain why American criminals prefer them over American bank issued cards, who have fraud detection in place 24x7. Read more...
