Weighted annual growth of CS publications compared to WoS total.
N = 1935. Search was conducted 2015-12-17 using the search string in S1 Appendix. Index value of 1 means that the same amount of articles was produced compared to previous year. Note: the 2015 numbers are incomplete because not all records have yet been added to the database at the time of search.

Conceptual structure of contemporary CS.
As described by a word co-occurrence network [32] based on keywords (original author keywords, delimited by article title) occurrence network for the search conducted on 2015-12-17 resulting in 1935 hits. To be included, each keyword needed to co-occur at least three times with the same keyword in the dataset. Proximity determined by the ForceAtlas2 algorithm [33] in the software package Gephi (version 0.8.2, http://gephi.org). The larger the node, the more frequently the keyword co-occurs (higher total degree). Colors are selected with the modularity filter for “community detection” [34]. Nodes have been moved slightly to make room for the textual labels.

Bibliographic coupling of sources.
Generated by VOSviewer [36]. Search conducted 2015-12-17 (S1 Appendix) in the Web of Science Core Collection resulting in 1935 hits. In these 165 sources were identified in cited references (minimum 3 documents of a source). Proximity is determined by bibliographic coupling [35].
