An efficient file structure for document retrieval in the automated office environment
Di Du, S. Ghanta, Karel Malý, S. M. Sharrock · IEEE Transactions on Knowledge and Data Engineering · 1989
A file system tailored to the general needs of the office environment is proposed. This system supports large numbers of a wide variety of documents and inexact fuzzy queries on the documents. The file system is based on a multilevel file structure that combines and extends multikey extendible hashing and signature files to create a document-retrieval system that is more time efficient than other previously proposed systems and is also space efficient.>
