Abstract:Real-time search requires to incrementally ingest content updates and almost immediately make them searchable while serving search queries at low latency. This is currently feasible for datasets of moderate size by fully maintaining the index in the main memory of multiple machines. Instead, disk-based methods for incremental index maintenance substantially increase search latency with the index fragmented across multiple disk locations. For the support of fast search over disk-based storage, we take a fresh l… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
