  • The first component includes three significant benefits related to information gathering (following other researchers' work, keeping up to date with topic, discovering new ideas or publications), and it explains 24% of the total variance. The second component includes significant benefits related to socializing and information dissemination (making new research contacts, promoting current work/research) and a negative relationship with “keeping up to date with topic”. It explains 16% of the total variance. By plotting the components in two dimensions, we discovered three clusters of related benefits, and not four as we initially anticipated (see Figure 1).

    13. 13. How to Make Sense of Social Big Data? Social Network Analysis (SNA) • Nodes = People • Edges /Ties (lines) = Relations/ “Who retweeted/ replied/ mentioned whom” Anatoliy Gruzd Twitter: @gruzd 14
    14. 14. Advantages of Social Network Analysis • Reduce the large quantity of data into a more concise representation • Makes it much easier to understand what is going on in a group Anatoliy Gruzd Once the network is discovered, we can find out: • How do people interact with each other, • Who are the most/least active members of a group, • Who is influential in a group, • Who is susceptible to being influenced, etc… Twitter: @gruzd 15
    15. 15. How Do We Collect Information About Online Social Networks? Common approach for collecting social network data: • Self-reported social network data may not be available/accurate • Surveys or interviews Problems with surveys or interviews • • • • • Time-consuming Questions can be too sensitive Answers are subjective or incomplete Participant can forget people and interactions Different people perceive events and relationships differently Anatoliy Gruzd Twitter: @gruzd 16
    16. 16. How Do We Collect Information About Social Networks? • Common approach: surveys or interviews • A sample question about students’ perceived social structures Please indicate on a scale from [1] to [5], YOUR FRIENDSHIP RELATIONSHIP WITH EACH STUDENT IN THE CLASS [1] - don’t know this person [2] - just another member of class [3] - a slight friendship [4] - a friend [5] - a close friend Alice D. [1] [2] [3] [4] [5] … Richard S. [1] [2] [3] [4] [5] Source: C. Haythornthwaite, 1999 Anatoliy Gruzd Twitter: @gruzd 17
    17. 17. How Do We Collect Information About Online Social Networks? Goal: Automated Networks Discovery Challenge: Figuring out what content-based features of online interactions can help to uncover nodes and ties between group members Anatoliy Gruzd Twitter: @gruzd 18
    18. 18. How to Make Sense of Social Media Data? Example: Twitter Network • Nodes = People @John • Ties = “Who retweeted/ replied/mentioned whom” • Tie strength = The number of retweets, replies or mentions @Peter @Paul Anatoliy Gruzd Twitter: @gruzd 19

    25. 25. Sample Project: Politics Social Media Use during the Canadian Federal Election • There are some pockets of political polarization on Twitter Conservative – homophily - when people in social networks tend to group around similar backgrounds and interests, including shared political views. Left Liberal • Twitter has potential for supporting open cross-ideological discourse Anatoliy Gruzd Unknown & Undecided Green Bloc – 43% of the accounts in the sample did not explicitly stated their support for any party or stated support to more than one party Spam NDP Other Manual Classification of Twitter Users based on their self-declared party affiliation Twitter: @gruzd 26

Sample Project: Health Health Care Social Media Canada Case Study: #hcsmca Twitter Community Background • #hcsmca is a vibrant community of people interested in exploring social innovation in health care. • #hcsmca hosts a tweet chat every Wednesday at 1 pm ET. The last Wednesday of the month is our monthly evening chat at 9 pm ET. Source: http://cyhealthcommunications.wordpress.com/hcsmca-2/ Anatoliy Gruzd Twitter: @gruzd 33
    33. 33. Sample Project: Health Health Care Social Media Canada Case Study: #hcsmca Twitter Community Research question: 1. What accounts for the relative longevity of this particular online community? – Is it because of the founder’s leadership and her continuing involvement in this community? – Or is there a core group of members who are also actively and persistently involved in this community? 2. What is the composition of this community? Does one’s professional role/title determine a person’s centrality within this community. Anatoliy Gruzd Twitter: @gruzd 34
