WhyPreprocessEnglishAbbreviationsinNLP?

PreprocessingEnglishabbreviationsinNLPiscrucialbecauseabbreviationscanhavemultiplemeaningsdependingonthecontextinwhichtheyareused.Failuretohandleabbreviationscorrectlycanleadtoinaccurateresults,asNLPalgorithmsmayinterprettheabbreviationinawaythatisdifferentfromwhatisintended.Forexample,theabbreviation\"FDA\"couldstandfor\"FoodandDrugAdministration\"or\"FederalAviationAdministration.\"Withoutproperpreprocessing,analgorithmmayconfusethetwomeaningsandproduceincorrectresults.
