Real-time structural motif searching in proteins using an inverted index strategy. [PDF]
PLoS Computational Biology, 2020 Biochemical and biological functions of proteins are the product of both the overall fold of the polypeptide chain, and, typically, structural motifs made up of smaller numbers of amino acids constituting a catalytic center or a binding site that may be ...

3iCubing: An Interval Inverted Index Approach to Data Cubes
IEEE Access, 2022 The increase in the amounts of information used to analyze data is problematic since the memory necessary to store and process it is getting quite big. The interval inverted index representation was developed to reduce the required memory to store data ...

Techniques for Inverted Index Compression [PDF]
ACM Computing Surveys, 2020 The data structure at the core of large-scale search engines is the inverted index , which is essentially a collection of sorted integer sequences called inverted lists . Because of the many documents indexed by such engines and stringent performance requirements imposed by the heavy load of ...

Reconfigurable Inverted Index [PDF]
Proceedings of the 26th ACM international conference on Multimedia, 2018 Existing approximate nearest neighbor search systems suffer from two fundamental problems that are of practical importance but have not received sufficient attention from the research community. First, although existing systems perform well for the whole database, it is difficult to run a search over a subset of the database.
