The Use of MMR and Diversity-Based Reranking for Reodering Documents and Producing Summaries

Summarization: (1) Using MMR for Diversity- Based Reranking and (2) Evaluating Summaries

This paper 1 develops a method for combining queryrelevance 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 reranking retrieved documents and in selecting appropriate passages for text summarization. Preliminary results indicate some benefits for MMR dive...

UPMC at MediaEval 2013: Relevance by Text and Diversity by Visual Clustering

In the diversity task, our strategy was to, first, try to improve relevance, and then to cluster similar images to improve diversity. We propose a four step framework, based on AHC clustering and different reranking strategies. A large number of tests on devset showed that most of the best strategies include text based reranking for pertinence, and visual clustering for diversity even compared ...

Rank Fusion and Multimodal Per-topic Adaptiveness for Diverse Image Retrieval

This paper presents the MultiBrasil team experience in the Retrieving Diverse Social Images Task at MediaEval 2017. The teams were required to develop a diversification approach for social image retrieval, enhanced with visual summarization. Our proposal for relevance improvement relies on text and credibility-based reranking and rank aggregation. For diversification, we use diversity-oriented ...
