SSI-Dijkstra-FirstSenses-P (hereinafter FSP) and SSI-Dijkstra-AllSenses-P (hereinafter ASP).
when a word is being disambiguated, these two versions consider the set I of already interpreted words of w and also the rest of words remaining in P. at each step, the algorithm selects the word sense which is closer to the set I of already disambiguated words and the remaining words of P all together.
