SPIRAL’s Autoindexing and Searching Algorithms

  • Leslie E. West


SPIRAL (Sandia Program for Information Retrieval) is a system for storage and retrieval of natural language text. This presentation reviews the data compression, indexing, and retrieval features of the system and gives a detailed explanation of the algorithms used in autoencoding, phrase searching, and vocabulary-pattern searching.
