The ISI subject categories classify journals included in the Science Citation Index (SCI). The aggregated journal-journal citation matrix contained in the Journal Citation Reports can be aggregated on the basis of these categories. This leads to an asymmetrical transaction matrix (citing versus cited) which is much more densely populated than the underlying matrix at the journal level. Exploratory factor analysis leads us to opt for a fourteen-factor solution. This solution can easily be interpreted as the disciplinary structure of science. The nested maps of science (corresponding to 14 factors, 172 categories, and 6,164 journals) are brought online at

We offer two metrics that together help gauge how interdisciplinary a body of research is. Both draw upon Web of Knowledge Subject Categories (SCs) as key units of analysis. We have assembled two substantial Web of Knowledge samples from which to determine how closely individual SCs relate to each other. “Integration ” measures the extent to which a research article cites diverse SCs. “Specialization ” considers the spread of SCs in which the body of research (e.g., the work of a given author in a specified time period) is published. Pilot results for a sample of researchers show a surprising degree of interdisciplinarity. Background Research spirals inward; science cascades outward. This dual image supports a vital realization – scientific advance requires knowledge transfer among researchers who

A journal set in an interdisciplinary or newly developing area can be determined by including the journals classified under the most relevant ISI Subject Categories into a journal-journal citation matrix. Despite the fuzzy character of borders, factor analysis of the citation patterns enables us to delineate the specific set by discarding the noise. This methodology is illustrated using communication studies as a hybrid development between political science and social psychology. The development can be visualized using animations which support the claim that a specific journal set in communication studies is increasingly developing, notably in the “being cited ” patterns. The resulting set of 28 journals in communication studies is smaller and more focused than the 45 journals classified by the ISI Subject Categories as “Communication. ” The proposed method is tested for its robustness by extending the relevant environments to sets including many more journals.

Abstract—In the last two decades, there have been studies claiming that science is becoming ever more interdisciplinary. However, the evidence has been anecdotal or partial. Here for the first time, we investigate a large size citation network of computer science domain with the intention to develop an automated un-supervised classification model that can efficiently distinguish the core and the interdisciplinary research fields. For this purpose, we propose four indicative features; three of these are directly related to the topological structure of the citation network, while the fourth is an external indicator based on the attractiveness of a field for the in-coming researchers. The significance of each of these features in characterizing interdisciplinarity is measured independently and then systematically accumulated to build an unsupervised classification model. The result of the classification model shows two distinctive clusters that clearly distinguish core and interdisciplinary fields of computer science domain. Based on this classification, we further study the evolution dynamics at a microscopic level to show how interdisciplinarity emerges through cross-fertilization of ideas between the fields that otherwise have little overlap as they are mostly studied independently. Finally, to understand the overall impact of interdisciplinary research on the entire domain, we analyze selective citation-based measurements of core and interdisciplinary fields, paper submission and acceptance statistics at top-tier conferences and the core-periphery structure of citation network, and observe an increasing impact of the interdisciplinary fields along with their steady integration with the computer science core in recent times.
