Supplemental Material for Symposium Bibliometric Analysis

<p>This site has raw data and results for bibliographic analysis of the INCOSE Symposium paper collection.</p>

<p class="Els-Abstract-text" style="text-align:justify"><span style="font-size:9pt"><span style="line-height:11pt"><span new="" roman="" style="font-family:" times="">To gain insights into the discipline of systems engineering, bibliometric analysis was performed on the text corpus of the abstracts from symposium papers of different eras of the INCOSE symposium and of the sources cited in symposium papers of different eras. The eras were decided based on cosine similarity analysis throughout 34 years of the symposium.</span></span></span></p>

<p class="Els-Abstract-text" style="text-align:justify"><span style="font-size:9pt"><span style="line-height:11pt"><span new="" roman="" style="font-family:" times="">Co-occurrence analysis was performed using VOSviewer, which is a software application that identifies pairs of terms from the abstracts of papers and connects them. This analysis found terms that occur together across multiple abstracts by applying a natural language processing algorithm that identified the terms and formed clusters of terms that are strongly related to each other. This process identified systems engineering trends in each era.</span></span></span></p>

<p class="Els-Abstract-text" style="text-align:justify"><span style="font-size:9pt"><span style="line-height:11pt"><span new="" roman="" style="font-family:" times="">Bibliographic coupling analysis and co-citation analysis were performed using VOSviewer. A bibliographic coupling link is a link between two papers that both cite the same source. A co-citation link is a link between two sources that are both cited by the same paper. The coupling analysis reflected prominent events and trends that appeared in systems engineering throughout the eras. The co-citation revealed information about the classification of authors contributing to symposium papers.</span></span></span></p>
