machine indexing
Quick Summary
Machine indexing is a method used in information retrieval to analyze the subject of electronic text. It involves assigning subject descriptors, either from an unlimited vocabulary (free indexing) or a predefined list (controlled indexing). The result is an inverted index, which lists descriptors and their locations within documents. Full-text indexing uses every word in a document as an access point, though this can demand significant computer storage. This process is crucial for organizing and retrieving information efficiently from digital databases.12
