[caption id="attachment_1992" align="alignleft" width="300"]Wordcloud of the #twitterstorians corpus[/caption]Last April, I started to collect tweets containing the hashtag #twitterstorians ((I also collect #digitalhumanities, #digitalhistory and #dighist)). The idea is to question whether it is possible to capture / understand in almost real time historiographies in the making. As you all know, this hashtag was created by Katrina Gulliver.After three months, I attempted to do a first text analysis of this #twitterstorians corpus - but it was still too tiny to be analysed. A few days ago, I attempted again to analyse it and it seemed to work, this time.I am using a software, iramuteq, developped by Pierre Ratinaud, assistant professor in Toulouse (South-Eastern France). Iramuteq is an interface to the statistical software R. Iramuteq allow to analyse raw texts, that are stored within a corpus that is very slightly encoded (FR). By the way, iramuteq is developped in several languages (including english) and can perform text analysis in French, English, German and more. So download it and try it!Corpus descriptionThe corpus was divided into 24613 texts and text units (between 13 and 14 words in each text units in average - in this case, as it is a corpus made of tweets, texts and text units are the same), with 33582 occurences and 19870 forms (the corpus is lemmatised). There are 2.39% of HAPAX (forms appearing only once) and they form around 40% of the occurrences.The analysesSimilitude[caption id="attachment_1990" align="aligncenter" width="300"]Result of the similitude analysis[/caption]ClassificationThe six classes    123456writeconferenceamrevoupacademicmilitaryirishhistorynewcallcw150profsocietyonthisdaywhatjournalcivilwarassociatesmh_historiansirelandhistorypostpaperworldhistorypageantannouncementbirthblogannuallizcovartbursarymilhistshkennaarchiveglobalallthingslibertymarkfreeman1974academicbornusihprogrammeklinecjahrcmembershipdublinknowonlineboston1775glasgowairmindedirishgreatsubmitgettysburgfundofficialdiethinkcasetodayinhistoryclosemilitaryhistoryinvinciblesteachduemorganahrcpresshistory1916risingloveworkshopedmundtudorfacebookmacneilllikeprogrampauluniofnottinghamhwarpoetresearchstudyrevolutionjandigestirelandbookproposalunderstandrakansaspatrickneedupdaterevolutionarystudentshipjundeathfindsymposiumearlyamhistcfpaprvaleragoodcfplincolnskill81stlimericktalkreleaserevwareconomichistoryddlnfoundlookimperialactsuccessionwestpoint_usmaleaderpodcastgeorgiangwbookslecturercheckexecutionlifecarnivalmyhnngrowmtgplunkettworkoctbostondeptfordmompstudentfrusegypttmrwpageeoinacwriseptemberliverpoolkclcanberrabrenmalonesocialhostconfederaterevealdatejamesbackpleasureapostlepaulosophdchatparnellwillparismaieremmalautmankeephungersurveyhistorycarnivalsuffragettesmokesemcasementreadfollowrevrebornhistorylabpluslinkcorkthoughtdeadlinepaulinerecordkeepingannthomastipeuropeloyalistangelabartielistexecuterobgreeneiinominationanimateformopportunitybelfastpastvisitabrahamsubmissioncrownkilmainhamsourcecollectioneconomicsreconstructresourceserieslibraryapplicationlandscapewcomehsseprisepublicremindermegankatenelsonphdwarleaguequestionrelevantmythimclunswstewarthashtagreportnationsuitfellowshiparchbishoptermmissfergusonfresherpreferhangffoxfordwomenshistoryagelaterossawebsiteregistrationspiritbritac_newsnetgaolthingjoincivilempirejobtreatythesisthe_oahgettysburg150londonersjulwynnsmaninternationaladdressryriebriancentenarynameshafrconferencepaintalecrapeunite19thcsexualityfrenchdurham_uninovpearsemeanseptforceprojectinterestruthhighereddancesoldieruniversitycityroscommonDendogram of the six classesConclusions: academic communication and Public HistoryThe #twitterstorians hashtag is firstly a communication channel, as the classification analysis is showing (classes 1 &#38; 2: books, articles, blogs for class 1 and CFPs, conferences for class 2) and also the similitude one. But looking at the four other classes, you remark that there are some domains that are more dynamic: Irish history, Military history, US history. In the details, notably in the similitude graph, you observe that those tweets are first concerning Public History (see the "onthisday" linked to "irishhistory" for instance). The similitude graph shows also some hashtags that are worth a harvest: #envhist, for instance.
