Models and Measures for Novel And Diverse Search results (MONADS)

The aim of this project is to research methods for ranking and evaluating automatic information retrieval system results for novelty and diversity. We focus on three related challenges: (1) how to identify different subtopics of a query? (2) how to diversify search results based on the subtopics? (3) how to evaluate diversification strategies?

The name MONADS is meant to reflect the idea that the traditional notion of "relevance" can be decomposed into simpler units---subtopics, aspects, nuggets, or monads of information---and the best way to improve a user's experience with a search engine is to try to identify these smaller units rather than broadly relevant documents.
