TheSixthInternationalConferenceonImplementationandApplicationof- tomata(CIAA2001)-the?rstoneheldinthesouthernhemisphere-was heldattheUniversityofPretoriainPretoria,SouthAfrica,on23-25July2001. ThisvolumeofSpringer'sLectureNotesinComputerSciencecontainsall thepapers(includingtheinvitedtalkbyGregorv. Bochmann)thatwerep- sentedatCIAA2001,aswellasanexpandedversionofoneoftheposterpapers displayedduringtheconference. Theconferenceaddressedtheissuesinautomataapplicationandimplemen- tion. Thetopicsofthepaperspresentedinthisconferencerangedfromautomata applicationsinsoftwareengineering,naturallanguageandspeechrecognition, andimageprocessing,tonewrepresentationsandalgorithmsfore?cientimp- mentationofautomataandrelatedstructures. Automatatheoryisoneoftheoldestareasincomputerscience. Researchin automatatheoryhasbeenmotivatedbyitsapplicationssinceitsearlystagesof development. Inthe1960sand1970s,automataresearchwasmotivatedheavily byproblemsarisingfromcompilerconstruction,circuitdesign,stringmatching, etc. Inrecentyears,manynewapplicationsofautomatahavebeenfoundin variousareasofcomputerscienceaswellasinotherdisciplines. Examplesofthe newapplicationsincludestatechartsinobject-orientedmodeling,?nitetra- ducersinnaturallanguageprocessing,andnondeterministic?
nite-statemodels incommunicationprotocols. Manyofthenewapplicationscannotsimplyutilize theexistingmodelsandalgorithmsinautomatatheorytosolvetheirproblems. Newmodels,ormodi?cationsoftheexistingmodels,areneededtosatisfytheir requirements. Also,thesizesofthetypicalproblemsinmanyofthenewapp- cationsareastronomicallylargerthanthoseusedinthetraditionalapplications. Newalgorithmsandnewrepresentationsofautomataarerequiredtoreducethe timeandspacerequirementsofthecomputation. TheCIAAconferenceseriesprovidesaforumforthenewproblemsand challenges. Intheseconferences,boththeoreticalandpracticalresultsrelatedto theapplicationandimplementationofautomatawerepresentedanddiscussed, andsoftwarepackagesandtoolkitsweredemonstrated. Theparticipantsofthe conferenceserieswerefrombothresearchinstitutionsandindustry. Wethankalloftheprogramcommitteemembersandrefereesfortheire?orts inrefereeingandselectingpapers.
