query-relevance with information-novelty in the context
of text retrieval and summarization. The Maximal
Marginal Relevance (MMR) criterion strives to reduce
redundancy while maintaining query relevance in
re-ranking retrieved documents and in selecting appropriate passages for text summarization. Preliminary results
indicate some benefits for MMR diversity ranking
in document retrieval and in single document summarization.
The latter are borne out by the recent results of the
SUMMAC conference in the evaluation of summarization
systems. However, the clearest advantage is demonstrated
in constructing non-redundant multi-document
summaries, where MMR results are clearly superior to
non-MMR passage selection.
