An algorithm to remove suffixes from words and reduce them to their stem, also taking into account the context. (Loterre)

All documents and the 6 financial sentiment word lists are stemmed by the Porter stemmer (Porter 1980) and some stop words are also removed. (Tsai & Wang, 2014)

The Porter stemmer (M.F. Porter 1980) developed the stemmer on the truncation of suffixes by means of list of suffixes and some restrictions/conditions are placed to recognize the suffix to be detached and generating a valid stem. (Khan, Anwar, Bajwa & Wang, 2012)
The second measure involves stemming which is reducing words into their base forms using the Porter stemmer (Porter 1980). (Alharbi & Gotoh, 2016)
When computing n-gram counts we applied Porter's stemmer to all tokens. (Paul & Dredze, 2013)
