Abstract: Information retrieval (IR) is the science of searching for
documents. Composite retrieval is the study of methods for creating,
retrieving and ranking composite responses such as sequences, or more
generally, items connected with some relationship. Different
applications induce star-shaped or chain-shaped items. Such items can be found in online
shopping and trip itinerary planning. In this talk, I will describe concrete applications
motivating composite retrieval and discuss how stars and chains affect relevance and
efficiency in online recommendations.
This is joint work with Senjuti Basu Roy (UT Arlington), Ronny Lempel
(Yahoo! Labs, Haifa), Gautam Das (UT Arlington) and Cong Yu (Google Inc).
