基于數(shù)據(jù)挖掘技術(shù)的印花稅“資金賬簿”品目欠稅分類研究的開題報(bào)告摘要：印花稅是我國固定資產(chǎn)投資項(xiàng)目的一項(xiàng)征收稅收，其征收方式主要是根據(jù)資金賬簿的內(nèi)容來計(jì)算征收稅額。在現(xiàn)實(shí)中，印花稅資金賬簿品目繁多、復(fù)雜，往往出現(xiàn)欠稅、誤稅等問題，嚴(yán)重影響到國家財(cái)政收入。因此，本文將運(yùn)用數(shù)據(jù)挖掘技術(shù)，對印花稅資金賬簿品目欠稅分類進(jìn)行研究，以期提高印花稅征收工作的效率和準(zhǔn)確率。本文將分析印花稅資金賬簿品目類別、欠稅原因、欠稅金額等多個(gè)方面的數(shù)據(jù)，運(yùn)用聚類分析、分類器、關(guān)聯(lián)規(guī)則挖掘等數(shù)據(jù)挖掘技術(shù)，對欠稅品目進(jìn)行分類研究。具體來說，本文將采用以下步驟：1.數(shù)據(jù)預(yù)處理：將印花稅資金賬簿數(shù)據(jù)進(jìn)行清洗和篩選，去除無關(guān)數(shù)據(jù)、缺失數(shù)據(jù)等，將數(shù)據(jù)轉(zhuǎn)化為可用的格式。2.特征選擇：根據(jù)對印花稅資金賬簿品目的了解，選擇合適的特征集，以便進(jìn)行欠稅品目分類研究。3.聚類分析：首先對印花稅資金賬簿品目進(jìn)行聚類分析，找出不同品目之間的相似性和差異性，從而為后續(xù)分析提供基礎(chǔ)。4.分類器：采用分類器對印花稅資金賬簿品目進(jìn)行分類，將欠稅品目與正常品目進(jìn)行分類。5.關(guān)聯(lián)規(guī)則挖掘：從欠稅品目的數(shù)據(jù)中挖掘出欠稅原因，欠稅金額的關(guān)聯(lián)規(guī)則，并根據(jù)規(guī)則進(jìn)行相應(yīng)的糾正和處理。6.結(jié)果分析：對以上步驟得出的結(jié)果進(jìn)行分析和驗(yàn)證，評估分類結(jié)果的準(zhǔn)確度和效率，并結(jié)合實(shí)際情況提出針對性的建議和措施。關(guān)鍵詞：數(shù)據(jù)挖掘；印花稅；資金賬簿；欠稅分類；聚類分析；分類器；關(guān)聯(lián)規(guī)則挖掘Abstract：StampdutyisataxonfixedassetsinvestmentprojectsinChina,anditscollectionmethodismainlybasedonthecontentsofthefundledgertocalculatetheamountoftaxtobecollected.Inreality,thevarietyandcomplexityofstampdutyfundledgeritemsoftenleadtotaxarrears,erroneoustaxesandotherproblems,whichseriouslyaffectthenationalfinancialrevenue.Therefore,thispaperwillusedataminingtechnologytostudytheclassificationoftaxarrearsinstampdutyfundledgeritems,inordertoimprovetheefficiencyandaccuracyofstampdutycollectionwork.Thispaperwillanalyzethedataofstampdutyfundledgeritems,suchasitemcategory,taxarrearsreasons,andtaxarrearsamounts.Dataminingtechniquessuchasclusteringanalysis,classifiers,andassociationruleminingwillbeusedtoclassifythetaxarrearsitems.Specifically,thispaperwilladoptthefollowingsteps:1.Datapre-processing:Cleanandselectstampdutyfundledgerdata,removeirrelevantdata,missingdata,etc.,andconvertthedataintousableformats.2.Featureselection:Selectasuitablefeaturesetbasedonanunderstandingofstampdutyfundledgeritemsfortaxarrearsclassificationresearch.3.Clusteringanalysis:First,carryoutclusteringanalysisonstampdutyfundledgeritemstofindsimilaritiesanddifferencesbetweendifferentitems,providingabasisforsubsequentanalysis.4.Classifier:Useaclassifiertoclassifystampdutyfundledgeritems,andclassifytaxarrearsitemsandnormalitems.5.Associationrulemining:Minetheassociationrulesoftaxarrearsreasonsandtaxarrearsamountsfromthedataoftaxarrearsitems,andcarryoutcorrespondingcorrectionsandprocessingaccordingtotherules.6.Resultanalysis:Analyzeandverifytheresultsobtainedfromtheabovesteps,evaluatetheaccuracyandefficiencyoftheclassificationresults,andproposetargetedrecommendationsandmeasuresbasedontheactualsi
