eBay Research Lab

eBay's search engine is one of the largest and most complex information retrie

val machines in the world. In order for the marketplace to work properly, all

of the information flowing through the site needs to be updated and searchable

in real-time. This includes the millions of items that enter and exit the sit

e every day, along with every bid placed, every listing update made and every

item purchased. To give you some perspective, each of the items listed on eBay

is updated an average of five times during its lifetime.

No off-the-shelf product available today is capable of this job, so we had to

develop our own search engine. eBay Research Labs developed a real-time search

engine with the ability to scale indefinitely. It uses a flexible attribute s

tructure and has built-in histogram functionality, allowing it to sort through

the 105 million listings on the site at any given time - all in real-time.

eBay Research Labs is now working on the next generation of search technologie

s. Search quality and relevance are important areas of research. An initial ve

rsion of relevant search is currently in use on eBay with the sort by "Best Ma

tch" feature, and we will soon be rolling out other versions on eBay.com. Thro

ugh great strides we've made in applying machine learning to our search engine

, search results will continue to become more relevant with each use.

The labs is also working on related areas like web-wide content aggregation, s

pam detection, content classification, content segmentation, productization, a

nd high performance search.
