PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21330321 Final results: The network evaluation discovered a coreperiphery structure exactly where central countries focused on active constructive discussions pertaining to e-cigarettes, while isolated and peripheral countries posted negative topics without the need of numerous responses. A qualitative examination of message topics suggests that basic subjects elicit a lot more interactions than these which might be context distinct. Conclusions: E-cigarettes are a polarising subject that may be seen in how nations seem to go over related subjects with other people who share precisely the same opinions. A lot more perform is necessary to help communities keep informed of present study, and diffuse objective details. Network and sentiment analyses supply a powerful combination of methodologies that can help help such efforts.Strengths and limitations of this studyThe study of e-cigarettes has usually focused on awareness plus the potential for advantages or harm. This paper takes a various strategy, and examines an international community of tobacco handle advocates, at a time when e-cigarettes had been nonetheless fairly unknown. We apply contemporary network and sentiment analysis techniques to supply a wealthy understanding in the attitudes and relationships in how a diverse community faced the challenge of an unexpected development in their efforts to help international tobacco handle. Our findings can help identify– even within a group of like-minded advocates– where gaps in communication, or differences in opinions, might exist and how they might be resolved. A single concern in making use of a dictionary of predefined sentiment scores may be the problem of context. Common scores are generally derived from large corpuses, but topic-specific studies could be sensitive to how certain terms are made use of. Applying a much more customised dictionary with improved semantic algorithms could support create extra accurate sentiment scores.Department of Preventive Medicine, University of Southern California, Los Angeles, California, USA Correspondence to Dr Kar-Hai Chu; karhaichusc.eduINTRODUCTION Info and communication technologies have develop into part of our daily lives.
