In this section of the article, we conduct a comprehensive literature review, that features the 10 most cited papers globally within the field of Cybernetics. This section provides valuable information, including the number of authors involved in each paper, the publication source, the year of publication, the total number of citations (TC), and the total number of citations per year (TCY) for each paper. Additionally, an indicator referred to as the normalized number of citations (NTC) is included, calculated by dividing the total number of citations for an article by the average number of citations received by all papers published in the same year. This analysis offers insights into the impact and relevance of these influential papers within the Cybernetics domain.
3.4.2. Top 10 Most Cited Papers—Review
The most cited papers had a crucial role in the evolution of Cybernetics and in this section, papers will be analyzed separately, to observe the contribution of each one.
Among the scholarly works in the field of cybernetics, Rhodes [
60] stands out as the most cited article, offering profound insights into the concept of “governance”, which was previously shrouded in ambiguity. Rhodes’ discourse meticulously dissects the multifaceted applications of governance from diverse perspectives, including its integration within socio-cybernetic systems. Moreover, Rhodes expounds upon essential characteristics inherent to the cybernetic paradigm, such as self-organizing networks and coordination. Notably, Rhodes underscores the importance of mutual adjustment and trust, elucidated through a real-world case study within the British government.
The second most influential article, penned by Wright [
61], delves into the realm of Human Resource Management (HRM), a domain traditionally lacking in comprehensive theoretical underpinnings. Wright embarks on the development of a novel framework known as Strategic Human Resource Management (SHRM), providing a rigorous foundation for HR practices. SHRM is scrutinized from various angles, including a cybernetic perspective, which aids in identifying optimal strategic and non-strategic HR practices. Wright further introduces robust models for power and resource dependence, albeit with recognized limitations, underpinning the overarching success of SHRM and its potential for refinement.
In the year 2000, Rose [
64] directed attention toward the control of different dimensions of illegal activities, advocating for the creation of accessible political programs and emphasizing the contemporary necessity of rehabilitation. Integral to this process is the restoration of moral order and the reintegration of affected individuals. Employing the framework of cybernetics, Rose offers a multi-dimensional exploration of illegalities and proffers strategies for aiding individuals in their journey back into society. This sensitive domain necessitates rigorous regulatory frameworks and adherence to established laws to ensure the seamless reintegration of individuals into society, free from complications. A pivotal advantage of utilizing cybernetics in this context is its inherent capacity for continuous feedback and adaptive responsiveness.
Rhodes [
67] is the most cited article on Cybernetics and the paper explains what “governance” is, a term which was unclear at that point. It presents the uses of governance from different perspectives, one of them being socio-cybernetic systems. Rhodes describes other characteristics of cybernetics, such as self-organizing networks or coordination. In the end, based on a real example from the British government, the author presents the most important characteristics for optimum governability: mutual adjustment and trust.
In the second most relevant article, Wright [
68] describes Human Resource Management (HRM), which does not have enough theoretical foundations, and tries to develop a new one called Strategic Human Resource Management (SHRM). SHRM is then presented from different perspectives, including the cybernetics point of view, which helps in finding the best strategic and non-strategic practices of HR. At the same time, Wright presented the optimum power and resource dependence models, which have some limitations but are working well and can be improved.
In 2000, Rose [
71] focused on how to control different regimes of illegalities, by creating political programs and providing access to every patient, rehabilitation is necessary in present times. They must recover their moral order and readapt their ration. Using cybernetics, the author tried to provide different dimensions of illegalities and show how to help people become reintegrated into society. It is a sensible domain, which requires a lot of regulations and laws to be implemented and respected, in order to make people rejoin society, without any issues. The big advantage of using cybernetics is the feedback that comes continuously, and it can adapt based on that.
A structured concept of Management Control Systems (MCS) has been described by authors [
72], providing solutions for actual problems from different perspectives, one of them being cybernetics. This approach helps to discover a distinction between manager behavior toward the employees and how this can affect decisions. In the end, a solution has been provided.
Walker and Cooper [
73] developed an article based on resilience, which appeared initially in the USA in the 1970s. They tried to adopt the existing theory, which was developed during the Cold War, the second-order cybernetics and complex systems theory, describing what resilience is, and how complex systems theory can be applied combined with contemporary neoliberal doctrines. Complex systems interfere with external factors and convert them into endogenous features, which help the system to adapt and remove perturbations. They also presented the evolution of cybernetics, complex system theory and how important it is, the impact of resilience, and how to use resilience instead of natural resource management.
The possibility of creating bionic organs [
70] is one of the most revolutionary events in medicine. Using cybernetics, the design and implementation of bionic devices have been simplified a lot, creating different scenarios and predictions on the resistance of materials, the compatibility of the human body, and functional electronic component durability. Since cybernetics is a complex system, which is changing based on the input. Using cybernetics, 3D printing Computer-Aided Design (CAD) was tested and implemented, helping millions of patients, by simulating different scenarios, materials, techniques, and technologies. The results confirmed what cybernetics showed previously: a huge success in creating cyborg ears that receive electromagnetic signals. This is only a small step compared with what cybernetics and medicine can achieve together.
Craig [
74] in his paper, tried to explain the theory of Communication using many areas, such as Cybernetics, which is highly sensitive to noise. The author concluded that if there is a mismatch between the function and structure of the problem, information processing will become difficult and the message will not be correctly and fully understood. Cybernetics distinguishes between mind and matter only from one perspective. The author predicts the future, trying to explain how robots will communicate with people at some point, having a crucial role in creating an “interpersonal” discussion. This makes Cybernetics one of the most powerful domains, with huge applicability, not only for humans but also for Artificial Intelligence. The act of communicating is difficult even for humans, with unpredictable and hard-to-understand behaviors, that is why Cybernetics has been used because it has the power to create many scenarios, to cover all the possibilities, but it can also step ahead, focusing on robots.
Another study presented the importance of Industry 4.0, a complex system that is computed by many technologies and design principles [
75]. From a Cybernetic point of view, Industry 4.0 is an evolution, adapting to the latest requirements in design and technology, making people more interested in it. The focus group consisted of students, helping them to create strategic roadmaps much more easily and offering the possibility to create priorities, budgets, capabilities, or goals. Cybernetics helped in developing the system, trying to gain feedback from the clients at every moment and adapting to their requirements. It is also useful to large companies because it can transform the activity of the employees, making them much more productive and efficient; however, this depends on the industry. Operational and strategic management is also available in Industry 4.0, Cybernetics created the optimum solution using one of its main characteristics, automatic adaptation.
Brechbühler et al. [
69] showed a parametric representation for a worldwide technique, creating 3D objects. The purpose of the paper is to explain and show object surfaces at a scale as close as possible to reality, based on shape descriptors. Authors skipped traditional limitations using cybernetics, by creating systems, comparing their behavior, and keeping the most suitable one. It is crucial to have a big resistance, a specific geometry. Everything can be tested with parametrization techniques. In the end, a model that describes the ideal 3D object based on different parameters was created.
The focus of the authors was on the Cybernetic Big Five Theory (CB5T) [
76], which provides a clear idea about the personality hierarchy based on three levels. Many hypotheses were tested (biological and psychological), trying to define some traits. CB5T offers continuous evolution and adaptation, which are specific to Cybernetics. It took some time to predict the adaptation characteristics because they are more complex and the personality is different from person to person, but in the end, there was a scenario that also included personalities and the evolution of each one. The trend of CB5T is positive and the mechanism has a self-adaptive architecture, receiving continuous data. However, there are some limitations as it is very difficult to predict personalities and how they can modify.
Table 7 provides a brief summary of the top 10 most globally cited documents, highlighting information related to the data used in the studies and their main purpose.
3.4.3. Words Analysis
In the subsequent analysis, we delve into identifying the most commonly used words in the selected papers, with the aim of gaining insights into the research methods and the scope of the studies. To commence, we conducted a search for the most frequently occurring words in the keywords plus section. Notably, the word “model” emerged as the most frequently used term, appearing 147 times. This was followed by “systems”, which occurred 135 times; “design” with 81 occurrences; “performance” with 64 occurrences; “dynamics” appeared 60 times; “growth” with 57 occurrences; and “framework” with 52 occurrences.
This analysis reveals that the majority of the words listed in
Table 8 are closely associated with the field of Cybernetics, describing its core concepts and characteristics and providing valuable insights into the nature of research within this discipline.
In
Table 9, we can see the top 10 words most frequently used by authors in their papers. As anticipated, the term “cybernetics” is the most prevalent, with an impressive 2218 occurrences. Alongside this fundamental term, other keywords closely associated with the field of Cybernetics include “systems theory” (185 occurrences), “modeling” (123 occurrences), and “artificial intelligence” (98 occurrences). Additionally, within the context of Cybernetics, it is noteworthy to mention “optimization” (70 occurrences), “systems” (68 occurrences), “design” (67 occurrences), “complexity” (65 occurrences), and “information” (63 occurrences). The recurrent use of these words by authors underscores their significance in Cybernetics research, reflecting their essential roles in shaping the discourse and methodology within the field. An illustrative instance of the convergence between cybernetics and “artificial intelligence” lies in their mutual pursuit of comprehending and emulating specific behavioral phenomena.
Figure 15 provides two word clouds, each representing the top 50 most commonly used words in the selected papers. These word clouds are generated based on two different sources: on the left side, we have the cloud of words derived from keywords plus, and on the right side, we have the cloud of words extracted from authors’ keywords.
In the left word cloud, we can identify various concepts frequently associated with the field of Cybernetics, such as “modelling”, “systems”, “design”, “information”, “performance”, “management”, “behavior”, “algorithm”, “networks”, “optimization”, “convergence”, “classification”, “organizations”, “algorithms”, “impact”, “selection”, and “communication”.
Conversely, the right word cloud prominently features the word “cybernetics”, reflecting authors’ frequent use of this term in titles, abstracts, and content. Additionally, other terms preferred by authors in the field of Cybernetics are visible, including “systems theory”, “modeling”, “artificial intelligence”, “optimization”, “automation”, “learning”, “computers”, “neural networks”, “cognition”, “research”, “control”, “simulation”, “decision making”, and “control systems”. These word clouds offer a visual representation of the key concepts and focal points within the domain of Cybernetics research.
Table 10 provides insights into the 10 most frequently encountered groups of two words or bigrams within the abstracts and titles of the analyzed articles.
In the left portion of the table, we observe the word groups extracted from the abstracts. The most common group, “systems theory”, appears 232 times, underscoring its significance in the domain of Cybernetics. Other frequently occurring groups include “second-order cybernetics” (216 occurrences), “artificial intelligence” (195 occurrences), and “social systems” (136 occurrences), all of which reflect key themes and topics within Cybernetics research.
In the right portion of the table, we find bigrams extracted from the article titles. Compared to the occurrences in abstracts, title-based bigrams typically have lower frequencies due to the limited number of characters in titles. The most frequent title-based bigrams include “contemporary systems” (63 occurrences), “cybernetic model” (57 occurrences), “cybernetic approach” (51 occurrences), “second-order cybernetics” (34 occurrences), “viable system” (33 occurrences), and “system model” (30 occurrences). These title-based bigrams provide insights into the specific areas of focus and emphasis within Cybernetics research articles. The occurrence of the “viable system” bigram within the top bigrams was expected, as the Viable System Model (VSM) is a cybernetic core component that was conceptualized to elucidate the adaptability of enterprises in the face of dynamic environmental changes. VSM serves as a framework for depicting the organizational structure of viable or self-regulating systems, comprising five interdependent subsystems. Its utility extends across diverse domains, ranging from operations management to educational contexts [
77]. On the other hand, even the occurrence of the “neural network” bigram was expected due to its connection with cybernetics. A neural network represents a machine learning approach that empowers computers to acquire knowledge from observational data. Network structures consist of interconnected nodes that exchange information via weighted connections, the weighting being contingent upon their capacity to yield specific outcomes [
78].
Table 11 provides insights into the top 10 trigrams or groups of three words with the highest frequencies of usage, both in the abstracts and titles of the analyzed articles.
In the left portion of the table, we observe the trigrams extracted from the abstracts. The most common trigram, “viable system model”, appears 103 times, indicating its significance in Cybernetics research. Other frequently occurring trigrams include “heinz von foerster” (49 occurrences), “system model vsm” (47 occurrences), “selected current research” (36 occurrences), “systemic yoyo model” (36 occurrences), “valuable periodic review” (33 occurrences), “adomian decomposition method” (32 occurrences), “beers viable system” (30 occurrences), “applied practical implications” (24 occurrences), and “artificial intelligence ai” (24 occurrences). These trigrams provide insights into specific topics and areas of focus within the field of Cybernetics.
On the right portion of the table, we find trigrams extracted from the article titles. The most frequent title-based trigram is “viable system model” (28 occurrences), followed by “heinz von foerster” (13 occurrences), “abstract neural automata” (7 occurrences), and “systems unitary science” (6 occurrences). Several trigrams registered 4 appearances each, including “air-force logistics command”, “contemporary cybernetics systems”, “cybernetic coping scale”, “cybernetic transportation system”, “cybernetics deviation-amplifying mutual”, and “cybernetics past achievements”. These title-based trigrams shed light on specific themes and topics emphasized in the titles of Cybernetics research articles. The occurrence of the trigram represented by the name of Heinz von Foerster was also expected due to his connection with the cybernetic field. More specifically, in 1974, Heinz von Foerster distinguished between first-order cybernetics and second-order cybernetics, emphasizing the absence of the observer’s role in first-order cybernetics. This variant underscores the significance of negative feedback and conceives the system as an independent entity. Conversely, second-order cybernetics introduces the quandary of impoverished closed-system dynamics. Furthermore, it adopts a reflective and philosophical stance, with a diminished emphasis on control mechanisms [
79].
In the following, we present some figures, made for the unigrams found in the titles, illustrating the thematic evolution (
Figure 16) and a thematic map (
Figure 17,
Figure 18 and
Figure 19) for the three periods of significant disturbances in the annual publication trends. Since some words represent specialized terms specific to cybernetics, we decided to eliminate some of them: “cybernetic”, “model”, “models”, “system”, “systems”, “theory”, and “approach”.
Figure 16 helps us to observe which words were the most frequent in the three identified time periods and how they were combined to form new terms. In the initial period, 1975–1987, the word “control” showed a merger with “contemporary”, “prediction”, and “science” into “information”. In turn, the word identified in the second period became the basis for the formation of other terms such as “development”, “analysis”, and “design”.
Most of the high-frequency words from the 1988–2016 period are combined and, in turn, form new terms describing cybernetics.
Figure 17 shows the highest frequency of certain unigrams at title level for the period 1975–1987. We can see that during this period, the emphasis was on “control” in the “Motor Therm” box and on “prediction”, but the orange bulb of this term is much smaller compared to the blue one. The term “control” is very important in cybernetics because it occurs when a closed system adjusts itself using a feedback loop. A high number of articles can also be seen in the “Basic Themes” quadrant, where most of them contain the word “modeling”.
Compared to the previous period (
Figure 17), in
Figure 18 (years 1988–2016) we can observe a higher number of articles in the “Basic Themes” quadrant, where the word “information” predominates in the titles, as opposed to the “Motor Themes” quadrant, where the bubble indicates the unigram “method”. During this period, most authors started to develop and use cybernetic methods for modeling. “Control” has now moved into the “Niche Themes” category, representing a sector that has already been explored.
In the most current period 2017–2022 (
Figure 19), the focus has shifted toward learning-related work. Cybernetics is a science that is constantly changing, and able to adapt and co-evolve. That is why learning in this field cannot end, making research extremely important. Compared to
Figure 18, the articles with the theme “analysis” have reached the border between the “Emerging of Declining Themes” and “Basic Themes” quadrant, previously being fully in the “Emerging of Declining Themes” and also having a smaller number of articles in its composition.
