#123456789#3.1 Visualization of the Organization’s Research Capacity and Degree of Interdisciplinary IntegrationTable 1 Classification of Research Fields─ 11 ─Related studies on “joint research between different organizations” can be found in Mizukami et al. (2016)8), who proposed a method for measuring these collaborations based on paper co-authorship, assuming that joint research within and outside the organization plays an important role in generating innovation to enhance its research capability. This method extends the concept of mediation centrality index of network theory to apply to organization theory, which allows for an aggregation of the connections within, outside, and inside the firm separately and the management of ease of information flow within and outside the organization, aiming at firms that innovate easily. This is an analytical framework for the “boundary spanner” presented by Leifer and Delbecq (1978)9) and Ancona and Caldwell (1992)10), and elaborated by Friedman and Podolny (1992)11) using social network theory.Table 1 shows how the research areas in this study are classified based on the Essential Science Indicators Subject Areas (Clarivate Analytics, n.d.) in the Web of Science (WoS) Core Collection.Mizukami et al. (2018) proposed deriving the field of expertise from authorship information for an objective definition3). Fig. 1(a) shows researcher A’s field of expertise and its applications.

Essential Science Indicators Subject Areas in the Web of Science Core Collectionmathematics (12), one in clinical medicine (4), one in economics and business (6), and one in general fields (15), his/her field of specialization is mathematics, with a 40% degree of concentration. If the degree of concentration is high, a researcher is considered to focus on research in his/her specialization field. Conversely, if the degree of concentration is low, a researcher is considered to apply research results in the specialized field to other fields.However, the information of each researcher shown in Fig. 1(a) does not show the connection between each research field unless it passes through the researcher located at the center of the Fig., and the linkage is unclear. Therefore, in this method, we used a simplified indication method for reconstructing the information about each researcher into the information between the fields. Fig. 1(b) shows an example of the simplified indication methods and the connection between each field is clarified.Fig. 1(b) shows the simplified field display method for researcher A. For example, clinical medicine (4) and mathematics (12) are connected through researcher A, and knowledge is shared. Thus, Fig. 1(b) shows how each field is linked through researcher A.Next, Fig. 1(d) superimposes researcher A in Fig. 1(b) and researcher B in Fig. 1(c) to show the organization’s research capabilities and cross-disciplinary integration. The thick line between business (6) and mathematics (12) in Fig. 1(d) represents the link between researchers A and B, while the thin line between the other fields are links through either researcher A or researcher B.
