Any largescale studies have examined scientists’ motivation for reside tweeting at conferences. Having said that,simply from reading conference tweets,a single can posit a number of causes. There is usually a clearly scientific aspect to a tweet: a user could possibly link to a preprint,by way of example. There might be an outreach aspect to a tweet: a person can use Twitter to attain networks outside of academe. A conference participant could tweet so that you can provide information and facts,along with a flavour in the occasion,to colleagues who can not attend. An increasingly preferred activity at scientific and technical conferences is a style of visual notetaking called sketchnoting; some participants pick to share their notes using a #sketchnote hashtag. A tweet can be a signifies of raising points of contention; one example is,the hashtag #everydaysexism has been utilized 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 applied by conference organisers as a channel for news,and delegates can make use of the service to ask for facts. The platform could be utilised by sponsors and exhibitors to promote their presence,and by local authorities to extol the virtues on the region surrounding the conference venue. A qualitative study would certainly ascertain but far more reasons why reside tweeting takes place at scientific conferences. The etiquette surrounding the usage of Twitter at scientific conferences continues to be evolving. One example is,in the annual meeting on the Ecological Society of America held in August ,the conference organisers’ request for attendees to get consent from speakers before tweeting about presentations triggered confusion (Woolston. There remains debate about no matter if conference policy need to default to enable live tweeting unless a speaker explicitly asks attendees not to do so. However,lots of conference organisers explicitly encourage delegates to tweet making use of a certain hashtag.Harvesting tweets for analysisSearching historical Twitter data is doable,but is usually expensive if a single wishes to carry out something besides fundamental analytics. However,Twitter makes publicly obtainable APIs that permit 1 to access its network stream in two unique strategies. The first technique enables a user,in true time,to harvest tweets that meet offered conditions; therefore a tweet containing a BMS-3 price particular hashtag can be piped to a file for later evaluation. The second system permits a user to search for and store all tweets posted within a preceding day period that meet given situations. These APIs gave sufficient access for the service for the purposes described within this paper.MethodsIdentification and classification of conferencesDuring PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/28497198 summer season ,a register of forthcoming academic conferences relating to subject regions in physics,astronomy and cognate disciplines was ready from public listings onTable Toplevel headings of PACS Classification Branch of physics or astronomy Basic 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 areas of science and technolog.
