IntroductionandProblemStatementIwouldliketocontinueexploringRbyapplyingittomyresearchareaofknowledgediscoveryusingbibliometricanalysis.Ihaveadatasetof~75kWebofSciencerecordsthatIhadpreviouslydownloadedforuseinCiteSpace.IfoundandinstalledanRpackage,Bibliometrix,(Aria,Corrado)thatappearstodomanyofthebibliometricanalysesandevenvisualizationsthatbibliometricresearchersusuallycreate.Iamnotcertainthatthistoolwillassistwiththe"knowledgediscovery"partofmyresearch;butthatwillbesomethingIwilllookfor.

DataSourcesandDataPreparation

DataAcquisition

IdownloadedbibliographicrecordsfromThomsonReutersWebofScience(WoS)(https://webofknowledge.com/).IhadpreviouslydownloadedonlyplaintextformatasthatcanbeusedinbothBibliometrixandCiteSpace.AfterthedataloadwithplaintextfilesintoRbecameexcruciatinglylong,Ire-downloadedtherecordsinbothBibTeXandplaintextformats.MyWebofSciencesessionwasabruptlystoppedandrestartedtwiceduringtheplaintextformat,whichmayhavecontributedtosomeoftheinconsistenciesIexperiencedlateron.IeventuallydecidedtocompletethetutorialusingonlytheBibTeXfiles.

Visualizingbibliographicnetworks

Multithreadedprocessing

RStudiotips
