In this chapter, the authors aim to recontextualise the local picture of youth participation in Manchester in a wider European perspective. First, because the research framework was a comparative European research project and, second, because the relevance also of local research depends on the degree to which it provides general insight into a phenomenon. The authors share with the editors and the other authors of this book the aim of questioning dominant understandings that limit youth participation to institutionalised forms and to young people’s involvement in existing practices and processes predefined by others, in most cases adult professionals like educators, youth workers and policy-makers. Based on the identification and discussion of three aspects related to the recognition of young people’s practice as participation in formal, non-formal and informal settings, the current authors want to use their views from the outside to shed light on the tensions and ambivalences of youth participation that do not become obsolete by applying a wider notion of participation.

The purpose of this paper is to explore the research status and development trend of the field of event detection in social media (ED in SM) through a bibliometric analysis of academic publications.

First, publication distributions are analyzed including the trends of publications and citations, subject distribution, predominant journals, affiliations, authors, etc. Second, an indicator of collaboration degree is used to measure scientific connective relations from different perspectives. A network analysis method is then applied to reveal scientific collaboration relations. Furthermore, based on keyword co-occurrence analysis, major research themes and their evolutions throughout time span are discovered. Finally, a network analysis method is applied to visualize the analysis results.

The area of ED in SM has received increasing attention and interest in academia with Computer Science and Engineering as two major research subjects. The USA and China contribute the most to the area development. Affiliations and authors tend to collaborate more with those within the same country. Among the 14 identified research themes, newly emerged themes such as Pharmacovigilance event detection are discovered.

This study is the first to comprehensively illustrate the research status of ED in SM by conducting a bibliometric analysis. Up-to-date findings are reported, which can help relevant researchers understand the research trend, seek scientific collaborators and optimize research topic choices.
