WebDec 11, 2024 · This paper describes a new representation of monotone sequences based on partitioning the list into chunks and encoding both the chunks and their endpoints with Elias-Fano, hence forming a two-level data structure that offers significantly better compression and improves compression ratio/query time trade-off. 109 PDF WebAug 22, 2016 · Elias-Fano encoding is quasi succinct, which means it is almost as good as the best theoretical possible compression scheme for sorted integers. While it can be used to compress any sorted list of integers, we will use it for compressing posting lists of inverted indexes. While gap compression has been around for over 30 years, and some of the ...
