Any largescale research have examined scientists’ motivation for reside tweeting at conferences. Nonetheless,just from reading conference tweets,one can posit a number of causes. There is certainly often a clearly scientific aspect to a tweet: a user may possibly link to a preprint,by way of 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 possibly tweet in an effort to deliver data,in addition to a flavour with the occasion,to colleagues who can not attend. An increasingly preferred activity at scientific and technical conferences is a style of visual notetaking referred to as sketchnoting; some participants opt for to share their notes applying a #sketchnote hashtag. A tweet is usually a means of raising points of contention; as an example,the hashtag #everydaysexism has been employed to flag conference speakers’ language or attitudes. A tweet can have a purely social aspect. Twitter can be applied for networking: employers can tweet the availability of jobs and postgraduates can enquire about possibleScientometrics :postdoctoral positions. Twitter is often utilized by conference organisers as a channel for news,and delegates can use the service to ask for information. The platform is often utilised by sponsors and exhibitors to promote their presence,and by neighborhood authorities to extol the virtues with the region surrounding the conference venue. A qualitative study would certainly ascertain yet far more causes why reside tweeting requires spot at scientific conferences. The etiquette surrounding the usage of Twitter at scientific conferences is still evolving. As an example,at the annual meeting of the Ecological Society of America held in August ,the conference organisers’ request for attendees to achieve consent from speakers just before tweeting about presentations triggered confusion (Woolston. There remains debate about no matter if conference policy need to default to let live tweeting unless a speaker explicitly asks attendees to not do so. Alternatively,several conference organisers explicitly encourage delegates to tweet making use of a certain hashtag.Harvesting tweets for analysisSearching historical Twitter data is achievable,but is usually costly if one particular wishes to carry out something besides simple analytics. On the other hand,Twitter tends to make publicly out there APIs that let 1 to access its network stream in two distinctive ways. The first technique enables a user,in true time,to harvest tweets that meet provided conditions; thus a tweet containing a specific hashtag is usually piped to a file for later evaluation. The second method permits a user to search for and store all tweets posted in a preceding day period that meet offered circumstances. These APIs gave adequate access to the service for the purposes described within this paper.MethodsIdentification and GNE-3511 web Classification of conferencesDuring PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/28497198 summer season ,a register of forthcoming academic conferences relating to topic areas in physics,astronomy and cognate disciplines was ready from public listings onTable Toplevel headings of PACS Classification Branch of physics or astronomy Common 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 locations of science and technolog.
