Text file inversion: An evaluation

ABSTRACT

This paper compares inversion of text files with inversion of more structured records. The unique characteristics of textual data which restrict the utility of inversion are identified and discussed. Inversion is shown to be useful only for small, static data bases, and when full text search is not required.
