Efore adopted: Retweets were excluded and Original tweets have been classified as becoming Science; Nonscience; Unclear; NonEnglish. Tweets within the NonEnglish category were not additional analysed; an evaluation by a native speaker could,of course,location them in any of your other categories. A typical example of a tweet classified as Science would be: “Margueron: Symmetry energy impacts T,s (but not density) post bounce,but incompressibility parameter does not change anything. #MICRA”. Nonscience tweets had been those referring to: basic conference management; announcements from publishers or exhibitors; EPZ031686 biological activity messages that focused on weather or the conference atmosphere; these that attempted humour; the (numerous) that mentioned meals and drink; and so on. A common instance of a tweet classified as Nonscience will be: “DSFD_Conference I heard a rumour of salmon. Rather excited! #DSFD”. A standard instance from the Unclear category could be: “Like The Devil ATLASexperiment #LeptonPhoton”. Table contains data on tweet kind for AstroParticle along with other conferences. In comparison with Other folks,a slightly reduced proportion of AstroParticle tweets are Original; PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/21666516 an alternative way of expressing this really is that a slightly higher proportion of AstroParticle tweets wereTable Variety of tweet AstroParticle of Original tweets Hyperlink Conversation .

This figure is in agreement with preceding studies (Honeycutt and Herring ; Boyd et alwhich recommended that about of tweets are conversational in nature. A rather greater proportion of Other tweets had been conversational: . . Similarly,a greater proportion of Other tweets than AstroParticle tweets contained hyperlinks vs Table includes information on the content material of Original tweets. As could be observed,the language of tweets is overwhelmingly English. Even though there is an inevitable element of subjectivity in classifying tweet content in this way,it appears clear that AstroParticle tweets are extra likely to focus on scientific problems than are tweets from Other conferences. Understanding the underlying supply of this distinction requires further investigation,but the observations talked about above motivate two tentative ideas that might be explored in extra detail in a qualitative study. First,delegates at Other conferences appear to use Twitter inside a additional conversational manner,and are probably as a result additional concerned in working with the service for social makes use of,than those at AstroParticle conferences. Second,as described in the “Twitter activity at conferences” section,AstroParticle conferences are extra most likely to include delegates which can be very active Twitter customers; in the event the motivation of these delegates is mostly to reside tweet concerning the science being discussed in conference presentations then this would assistance ex.
