SIGIR '13: Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrievalCurrent approaches for search result diversification have been categorized as either implicit or explicit. The implicit approach assumes each document represents its own topic, and promotes diversity by selecting documents for different topics based on ...
Modeling Intent Graph for Search Result Diversification
SIGIR '21: Proceedings of the 44th International ACM SIGIR Conference on Research and Development in Information RetrievalSearch result diversification aims to offer diverse documents that cover as many intents as possible. Most existing implicit diversification approaches model diversity through the similarity of document representation, which is indirect and unnatural. To ...
