[17]。無監(jiān)督的提取方法不需要對模型進行多次訓練與測試，并且不需要進行人工操作，就是講提取方法看做是一個排序方法，根據(jù)所選擇的算法，將文本中的關鍵詞提取出來，根據(jù)不同的權重來進行關鍵詞排序，選擇權重最高的幾個關鍵詞作文本的關鍵詞。實現(xiàn)較為方便快捷，也能較準確提出所需關鍵詞。參考文獻蘇超.基于多屬性融合的關鍵詞提取研究[D].中國民航大學,2020.常耀成,張宇翔,王紅,萬懷宇,肖春景.特征驅(qū)動的關鍵詞提取算法綜述[J].軟件學報,2018,29(07):2046-2070.PeterD.Turney.LearningAlgorithmsforKeyphraseExtraction[J].InformationRetrieval,2000,2(4).FrankE,PaynterGW,WittenIH,GutwinC,Nevill-ManningCG.Domain-Specifickeyphraseextraction.In:Proc.oftheIJCAI.SanFrancisco:MorganKaufmannPublishersInc.,1999.668–673.FeiXieandXindongWuandXingquanZhu.Efficientsequentialpatternminingwithwildcardsforkeyphraseextraction[J].Knowledge-BasedSystems,2017,115:27-39.GonencErcan,IlyasCicekli.Usinglexicalchainsforkeywordextraction[J].InformationProcessingandManagement,2007,43(6).AdebayoKolawoleJohn,LuigiDiCaro,GuidoBoella.ASupervisedKeyPhraseExtractionSystem[P].SemanticSystems,2016.JiabingWang,HongPeng.KeyphrasesExtractionfromWebDocumentbytheLeastSquaresSupportVectorMachine[P].WebIntelligence,2005.陳憶群,周如旗,朱蔚恒,李夢婷,印鑒.挖掘?qū)＠R實現(xiàn)關鍵詞自動抽取[J].計算機研究與發(fā)展,2016,53(08):1740-1752.MouniaHaddoud,Sa?dAbdedda?m.Accuratekeyphraseextractionbydiscriminatingoverlappingphrases[J].JournalofInformationScience,2014,40(4).SarkarK,NasipuriM,GhoseS.Machinelearningbasedkeyphraseextraction:Comparingdecisiontrees,Na?veBayes,andartificialneuralnetworks.JournalofInformationProcessingSystems,2012,8(4):693–712.[doi:10.3745/JIPS.2093]QiZhang,YangWang,YeyunGong,etal.KeyphraseExtractionUsingDeepRecurrentNeuralNetworksonTwitter[C]//Proceedingsofthe2016ConferenceonEmpiricalMethodsinNaturalLanguageProcessing.2016.C.Zhang，H.Wang，Y.Liu，D.Wu，B.Wang.AutomaticKeywordExtractionfromDocumentsUsingConditionalRandomFields[J].JournalofComputationalInformationSystems,2008,4.HofmannK,TsagkiasM,MeijE,DeRijkeM.Acomparativestudyoffeaturesforkeyphraseextractioninscientificliterature.趙林靜.結(jié)合語義相似度改進LDA的文本主題分析[J].計算機工程與設計,2019,40(12):3514-3519.MihalceaR,TarauP.TextRank:BringingOrderintoTexts[C]//ProcConferenceonEmpiricalMethodsinNaturalLanguageProcessing.2004.JavadRafiei-Asl,AhmadNickabadi.TSAKE:Atopicalandstructural
