Any largescale studies have examined scientists’ motivation for reside tweeting at conferences. Even so,just from reading conference tweets,one can posit several causes. There is certainly typically a clearly scientific aspect to a tweet: a user may link to a preprint,for example. There can be an outreach aspect to a tweet: an individual can use Twitter to attain networks outside of academe. A conference participant may tweet in an effort to provide information,as well as a flavour of the event,to colleagues who cannot attend. An increasingly common activity at scientific and technical conferences is a style of visual notetaking called sketchnoting; some participants decide on to share their notes utilizing a #sketchnote hashtag. A tweet can be a implies of raising points of contention; for instance,the hashtag #everydaysexism has been used to flag conference speakers’ language or attitudes. A tweet can have a purely social aspect. Twitter might be utilized for networking: employers can tweet the availability of jobs and postgraduates can enquire about possibleScientometrics :postdoctoral positions. Twitter may be made use of by conference organisers as a channel for news,and delegates can make use of the service to ask for data. The platform is often made use of by sponsors and exhibitors to advertise their presence,and by regional authorities to extol the virtues in the location surrounding the conference venue. A qualitative study would surely decide yet much more reasons why live tweeting takes spot at scientific conferences. The etiquette surrounding the usage of Twitter at scientific conferences continues to be evolving. One purchase NAMI-A example is,in the annual meeting of your Ecological Society of America held in August ,the conference organisers’ request for attendees to acquire consent from speakers prior to tweeting about presentations triggered confusion (Woolston. There remains debate about no matter if conference policy should really default to permit live tweeting unless a speaker explicitly asks attendees to not do so. Alternatively,a lot of conference organisers explicitly encourage delegates to tweet employing a particular hashtag.Harvesting tweets for analysisSearching historical Twitter data is probable,but might be pricey if a single wishes to carry out something apart from basic analytics. Nevertheless,Twitter tends to make publicly obtainable APIs that allow 1 to access its network stream in two distinct techniques. The very first process enables a user,in real time,to harvest tweets that meet provided circumstances; therefore a tweet containing a certain hashtag might be piped to a file for later analysis. The second system permits a user to look for and shop all tweets posted inside a preceding day period that meet given conditions. These APIs gave adequate access to the service for the purposes described in this paper.MethodsIdentification and classification of conferencesDuring PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/28497198 summer time ,a register of forthcoming academic conferences relating to subject locations in physics,astronomy and cognate disciplines was prepared from public listings onTable Toplevel headings of PACS Classification Branch of physics or astronomy General The physics of elementary particles and fields Nuclear physics Atomic and molecular physics Electromagnetism,optics,acoustics,heat transfer,classical mechanics,and fluid dynamics Physics of gases,plasmas,and electric discharges Condensed matter: structural,mechanical,and thermal properties Condensed matter: electronic structure,electrical,magnetic,and optical properties Interdisciplinary physics and connected places of science and technolog.
