Succinct Data Structures for NLP-at-Scale

no code implementations COLING 2016 Matthias Petri, Trevor Cohn

Succinct data structures involve the use of novel data structures, compression technologies, and other mechanisms to allow data to be stored in extremely small memory or disk footprints, while still allowing for efficient access to the underlying data.
