This manuscript explores the research topics and collaborative behaviour of authors in the field of the Prisoner’s Dilemma using topic modeling and a graph theoretic analysis of the co-authorship network. The analysis identified five research topics in the Prisoner’s Dilemma which have been relevant over the course of time. These are human subject research, biological studies, strategies, evolutionary dynamics on networks and modeling problems as a Prisoner’s Dilemma game. Moreover, the results demonstrated the Prisoner’s Dilemma is a field of continued interest, and that it is a collaborative field compared to other game theoretic fields. The co-authorship network suggests that authors are focused on their communities and that not many connections across the communities are made. The most central authors of the network are the authors connected to the main cluster. Through examining the networks of topics, it was uncovered that the main cluster is characterised by the collaboration of authors in a single topic. These findings add to the bibliometrics study in another field and present new questions and avenues of research to understand the reasons for the measured behaviours.

该手稿使用主题建模和共同作者网络的图论分析来探讨囚徒困境领域的研究主题和作者的协作行为。分析确定了“囚徒困境”中的五个研究主题，这些主题随着时间的流逝一直很重要。这些是人类主题研究，生物学研究，策略，网络演化动力学以及作为囚徒困境游戏的建模问题。而且，结果表明《囚徒困境》是一个持续引起人们关注的领域，并且与其他博弈论领域相比，它是一个协作领域。共同作者网络建议作者专注于他们的社区，并且社区之间没有多少联系。网络中最主要的作者是连接到主群集的作者。通过研究主题网络，我们发现主集群的特点是单个主题中作者的协作。这些发现增加了另一个领域的文献计量学研究，并提出了新的问题和研究途径，以了解测量行为的原因。
