“…Finally, using networks based on which users follow each other does not necessarily capture all of the interactions that occur online. While some argue that interaction with content (liking or retweeting) is a better measure of impact than followers, 90 others have argued that many users on Twitter are passive and do not interact with the content, 91 and as such, followers may be a better indicator of impact. As this study examined follower networks, it would be helpful for future research to compare followers to different ways of interacting with content in order to better understand the impact of HPV vaccine tweets.…”

ObjectiveOpposition to human papillomavirus (HPV) vaccination is common on social media and has the potential to impact vaccine coverage. This study aims to conduct an international comparison of the proportions of tweets about HPV vaccines that express concerns, the types of concerns expressed and the social connections among users posting about HPV vaccines in Australia, Canada and the UK.DesignUsing a cross-sectional design, an international comparison of English language tweets about HPV vaccines and social connections among Twitter users posting about HPV vaccines between January 2014 and April 2016 was conducted. The Health Belief Model, one of the most widely used theories in health psychology, was used as the basis for coding the types of HPV vaccine concerns expressed on Twitter.SettingThe content of tweets and the social connections between users who posted tweets about HPV vaccines from Australia, Canada and the UK.Population16 789 Twitter users who posted 43 852 tweets about HPV vaccines.Main outcome measuresThe proportions of tweets expressing concern, the type of concern expressed and the proportions of local and international social connections between users.ResultsTweets expressing concerns about HPV vaccines made up 14.9% of tweets in Canada, 19.4% in Australia and 22.6% in the UK. The types of concerns expressed were similar across the three countries, with concerns related to ‘perceived barriers’ being the most common. Users expressing concerns about HPV vaccines in each of the three countries had a relatively high proportion of international followers also expressing concerns.ConclusionsThe proportions and types of HPV vaccine concerns expressed on Twitter were similar across the three countries. Twitter users who mostly expressed concerns about HPV vaccines were better connected to international users who shared their concerns compared with users who did not express concerns about HPV vaccines.

“…Starting from the above-mentioned position, for the purposes of this study, 7 client activities in SM were defined within the scope of the SM category of Visibility. Consequently, the hypothesis H1 (with the sub-hypotheses H1.1 -H1.7 shown in S1 Appendix) was defined to test the importance of SM visibility (and its associated activities) for KM in companies offering knowledge-based services: H1: The SM Visibility is important for KM Thanks to various client activities, SM generates content that can be used independently of the time of creation, most often as inherited knowledge [65]. Thus, Danis and Singer [66] recognize SM as an IT resource where users consciously leave information about current projects and competencies of those engaged in these projects, which can all serve as knowledge for future use.…”

The existing literature fails to identify to which extent the utilization of social media could be relevant for increasing the effectiveness of knowledge management, in respect to overall business operations. In order to shed some light on this area we define three goals. Firstly, we investigate to what extent the different activities of clients on social media (SM), are important to the processes of knowledge management (KM) in companies. Secondly, we examine to what extent KM functions can be relevant in attaining the quality of IT services. Thirdly, we analyze to what extent KM mediates between SM and the quality of IT services, that is, which client activities on SM should be formalised in the form of KM processes so as to influence the quality of IT services. In order to asses these goals, the decision tree method was used at the sample of B2B companies, more specifically at the sample of those companies offering Knowledge Intensive Business Services (KIBS). The study has shown that: (i) SM client activities have the largest importance for building efficient KM; (ii) KM functions are relevante to the overall quality of IT services, and (iii) those SM options and activities have been identified, whose importance for the assessment of the quality of IT services is indirectly transmitted through KM. This paper offers new empirical evidence which can lead to a better understanding of the role of KM in KIBS. Thanks to the obtained findings, managers will be able to define the goals of their companies in relation to the utilization of SM, more specifically: their presentation on SM, monitoring the outcomes of the SM, usage improving their KM practices and, thus, define strategies to increase the quality of the IT services they offer.

“…Twitter, as a free website, is a good platform for the enterprise to promote their products and services. The propagation of the message within Twitter is a hot topic for scientists to study on [13]. Qualitative analysis used in finding crucial users in Twitter is very meaningful for doing effective advertising for the company [14].…”

The analysis of influence in social network is drawing more and more attention. It can be applied in different areas such as political campaigns and marketing. In this work, the analysis of influence in Twitter, based on users" profile statistics in a real-time scale, was studied and discussed. Two methods of identifying influential users by given keyword in real-time are introduced. To understand the relationship between users" influence features and social states in real life, two influence measures were presented: Local Influence which the user has on his/her immediate set of contacts and global Influence which the user has on the entire social network. This study describes in details these two metrics and shows their implementation for a real social network. Our case study, using Twitter, showed that the proposed model can create clusters of users in 2D space corresponding to their social standing, and can further be used to classify previouslyunseen users into the correct classes with an f-measure of 0.82 which is significantly higher than benchmark algorithms. F-measure is often used for measuring the accuracy of the test for classification.
