Background • Networking functionality of Twitter between users sometimes outweigh its informational use . • There is evidence that majority of users with tweets to articles believe Twitter is an important platform in creating opportunity of account following and developing network of connections .

Research Questions 1. How much users tweeting the articles are in each other’s network ? 2. How consistently did users follow the practice of tweeting field’s articles? 3

Dataset & Method: Sample Followers Following • All 7,323 articles with tweets of The User Astrophysical Journal in 2011 to 2015 • 5,283 unique Twitter users was searched in Twitter.com using API for only following users or friends’ data, finding 5,017,615 friendships. • API restriction! Friends data were Limitations not completely downloadable for 160 accounts (3%) with over 5000 friends. • 659 accounts (12%) had not No Following! networked with any friends. 4

How much users tweeting the articles are in each other’s network ? 5,283 User/Follower Tweet 29,650 Articles Users Tweet Following with tweets in Following field of Astronomy Tweet Tweet and Astrophysics Friend/Following 31,051 unique Twitter users Tweeting the same article Tweeting the same field 5

How much users tweeting the articles are in each other’s network ? Tweeting articles in Astronomy and Astrophysics User Tweet Articles in the field Following of Astronomy 80% of Twitter users and followed users tweeting Tweet Astrophysics articles in the same field Friend Followers with the highest number of friends with tweets in field were academic researchers and publishers. Popular friends were space organizations and projects and news feeds. @NASA @NASAKepler @SPACEdotcom 6

Friendship Patterns between Users Present In Tweeting the Same Article Unique Twitter Users Articles With at least one 65% in a friendship network Follower-Following (41%) 58% Followers -> 35% Followings Mutual Friendship (18%) 28% in Mutual Friendship

How consistently users follow the practice of tweeting field’s articles? 80% 11% 4% 1.8% 1.2% 0.8% 0.6% 8

Conclusions • Most Twitter users only have a limited contribution in Astronomy and Astrophysics research diffusion. • Friendship is a significant factor in the involvement of majority of users in the broader diffusion of minority of articles. • Most Users either favour retweeting articles from friends or non- friends. These two distinct behaviour of users can be interesting research topic for further speculation. • Other research fields might show different friendship impact due to disciplinary differences in Twitter uptake. 9
