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
Theresultingimages(whichyoucanseeintheappendix)wereprettytolookatandatleastshowedthenode;buttheyareverypracticalwithoutthecorrespondingedges.Inmanyofthegraphs,thelinesbetweennodesarenotrendering.Isuspectitmaybeduetothenumberofnodesinmydatasetoverwhelmingtherenderer.Thisisdefinitelyanissuetoinvestigatefurther.IamdisappointedthatIcouldnotgenerateseveralofthenetworkgraphsthatgaveabetteroverviewofhowthedomainisconceptuallystructured.TheRStudiosessionwouldunexpectedlyabortwhilerunningthefunction.Ihavebeentweakingsomeoftheargumentsinthesefunctions;buthaven’tfoundthemagiccombinationsyet.(Admittedly,whenafunctionwouldtakeanhourormore,IshouldbelookingattheratherlargedatasetIloadedtotakesomeoftheblame.)

Multithreadedprocessing
