Abstract: This dissertation proposes a framework capable of capturing the dynamic and interactive nature of scholarly communication. This framework is applied to a scholarly data set of library and information science literature with the goal of addressing four essential topics in scholarly communication, regarding the conduct of scientific impact evaluation, the exploration of scientific collaboration, the identification of research specialties and topics, and the study of scientific knowledge flow patterns. Several types of scholarly networks are employed as the research instrument to address these four areas, including coauthorship networks, citation networks, co-citation networks, bibliographic coupling networks, topic modeling/networks, and heterogeneous networks. Conceptually, a well-defined framework for quantitative study of scholarly communication is developed; methodologically, the outcome is a set of systematic approaches to evaluate impact (i.e., topic-based PageRank), explore collaboration (i.e., a mix method incorporating community detect, linear regression, and link prediction), identify research topics and specialties (i.e., topic dynamic attributes), and study knowledge flow (i.e., scientific trading and knowledge paths); and empirically, a systematic investigation of scholarly communication (in the above mentioned aspects) in the field of library and information science is accomplished. |
