SÃ©bastien Billard sent me a heads up on an interview that he has conducted with Danica Brinton, who is the head of International Product Management and Localization for Ask.com – Interview avec Danica Brinton (Ask.com).
While the original is in French, SÃ©bastien has also translated it into English. There’s a link to the English version in pdf format in the first paragraph of the French version. There’s some great information here on how Ask’s blog search works. Here’s a snippet:
Because Bloglines is the largest and longest established major blog reading community online, Ask Blog & Feed Search also has the most robust index of content on the Web: articles are indexed from 2001 through five minutes ago (or less). New posts are added at a rate of four to six million per day, with a total index in excess of 1.5 billion articles, with 4 to 6 million added every day.
The interview also describes different ways that search results can be sorted, and provides some insight into the ExpertRank algorithm.
SÃ©bastien asks some great questions, and in a couple of places some tough questions, on topics such as the use of accents, the inclusion of Digg-like results in the blog search, and more. Highly recommended.
