===Sense inventory and algorithms' task-dependency===
A task-independent sense inventory is not a coherent concept:{{sfn|Palmer|Babko-Malaya|Dang|2004|pp=49–56}} each task requires its own division of word meaning into senses relevant to the task. Additionally, completely different algorithms might be required by different applications. In machine translation, the problem takes the form of target word selection. The "senses" are words in the target language, which often correspond to significant meaning distinctions in the source language ("bank" could translate to the French {{Lang|fr|banque}} – that is, 'financial bank' or {{Lang|fr|rive}} – that is, 'edge of river'). In information retrieval, a sense inventory is not necessarily required, because it is enough to know that a word is used in the same sense in the query and a retrieved document; what sense that is, is unimportant.
