Purpose – The automatic removal of suffixes from words in English is of particular interest in the field of information retrieval. This work was originally published in
Design/methodology/approach – An algorithm for suffix stripping is described, which has been implemented as a short, fast program in BCPL.
Findings – Although simple, it performs slightly better than a much more elaborate system with which it has been compared. It effectively works by treating complex suffixes as compounds made up of simple suffixes, and removing the simple suffixes in a number of steps. In each step the removal of the suffix is made to depend upon the form of the remaining stem, which usually involves a measure of its syllable length.
Originality/value – The piece provides a useful historical document on information retrieval.
