Vik Singh, a developer in the Yahoo! Search BOSS team, is the brains behind the BOSS Mashup Framework. Since last summer, he has built many sample apps using the framework. Most recently Vik released an informal mashup (not an official Yahoo! product) called TweetNews, which fuses Yahoo! News with the Twitter API to provide a new ranking model for breaking news queries. Vik took some time to answer our questions about his new application, creative uses of BOSS, and future innovations in search.
