The research team, led by Le Pham Tan Quoc of the Industrial University of Ho Chi Minh City together with collaborators in Vietnam and Hungary, used RStudio with the Bibliometrix package and its Biblioshiny interface, complemented by VOSviewer for network visualization. Their search strategy combined the terms wild boar or Sus scrofa with meat quality, carcass traits, fatty acid, or nutritional composition, and after filtering to original research articles only, the team retained 423 publications for analysis. By applying performance indicators, co-authorship networks, keyword co-occurrence mapping, Multiple Correspondence Analysis, and thematic evolution analysis, the study addressed six core research questions covering publication growth, influential contributors, collaboration patterns, citation impact, dominant themes, and emerging trends.

The historical picture that emerges is striking. The first recorded publication appeared in 1959, but output remained sparse and sporadic through the 1960s and 1980s, when wild boar meat was treated largely as a side topic within wildlife and ecological research. From the mid-1990s, publication numbers began to climb as interest in alternative protein sources grew, and by 2003 the field recorded 18 papers in a single year, marking a transition toward systematic study. Advances in biochemical analytical methods, particularly for determining fatty acid composition, helped drive this shift, alongside rising consumer appetite for game meat as a natural, organic protein source and growing concerns about the environmental footprint of conventional livestock production.

Between 2006 and 2014, the field entered a phase of strong and relatively stable growth, with several years exceeding 20 publications. During this period, studies increasingly focused on the nutritional value, fatty acid profiles, and potential health benefits of wild boar meat compared with commercial pork. The expansion of wild boar populations across Europe also played a role, as wildlife managers sought productive uses for animals that increasingly required population control. From 2015 to 2024, output fluctuated but remained high, with research expanding into sensory quality evaluation, food safety, and the effects of hunting season, geographic region, and semi-wild production systems on meat characteristics.

Compared with intensively farmed pigs, wild boar meat generally shows lower fat content, firmer muscle structure, and higher protein levels. Its fatty acid profile contains higher proportions of polyunsaturated fatty acids, particularly omega-3 and omega-6 varieties, depending on natural feeding conditions and habitat. Quality assessment relies on indicators including pH, color, tenderness, water-holding capacity, fat-to-lean ratio, and sensory traits, while carcass characteristics such as weight, backfat thickness, and loin eye area reflect growth performance and processing potential. These parameters are significantly influenced by sex, age, hunting season, geographic location, and ecological conditions, which helps explain why the field spans so many disciplines and methodologies.

The author-level analysis revealed a highly specialized field shaped by a limited number of core research groups. Geldermann H leads productivity with 21 publications, followed by Bartenschlager H with 20 and Moser G with 16, and these three also top the citation rankings. Yet fractionalized counts, which reflect individual contribution within large collaborations, tell a subtler story: Razmaite V, with 15 publications, achieved the highest fractionalized value of 6.58, indicating a comparatively greater personal contribution, while Groenen M attained the highest average citations per article at 11.70. Journal of Animal Science and Meat Science dominate both productivity and citation impact, and the strong presence of Animal Genetics, Journal of Animal Breeding and Genetics, and Genetics Selection Evolution underscores how tightly meat quality research is bound to quantitative genetics.

Geographically, China leads in total publications, with most classified as single-country publications reflecting strong domestic research capacity, while Germany ranks second with a notably higher proportion of internationally co-authored work. Poland and Italy also contribute substantially, largely through domestic output, and the United States shows a balanced distribution that positions it as a connecting hub in the global network. The authors attribute the strong European presence to high wild boar population densities, long-term pig genetics programs, and policy pressures linked to wildlife management, whereas China’s dominance reflects substantial national investment in agricultural and animal science research.

Perhaps the most compelling finding is the field’s intellectual evolution. Thematic mapping across three periods shows that early research centered on intramuscular fat, carcass traits, and lipid metabolism in domestic pigs, with comparative studies between wild boar and commercial breeds. The middle period from 2011 to 2018 diversified into species identification, skeletal muscle biology, and performance evaluation, while the most recent phase from 2019 to 2026 consolidates around genomic characterization, with terms such as candidate genes, genome-wide association studies, and differentiation between wild and domestic populations taking prominence. Overlay visualization confirms that genetic and genome-mapping terms dominated early periods, while fatty acids, genome scan analysis, and meat quality traits have become increasingly prominent in recent years.

Multiple Correspondence Analysis crystallized this structure into three conceptual pillars that together explain more than 81 percent of the dataset’s variance across two dimensions. The first cluster encompasses genetic improvement and production traits such as growth, quantitative trait loci, and backfat thickness; the second captures molecular genetics, including gene expression, linkage, and candidate gene identification; and the third groups meat quality and lipid characteristics, including muscle composition, fatty acids, and physicochemical properties. The spatial proximity of these clusters in the analysis suggests growing integration between genetics and meat science, even as each direction maintains its own specialized identity.

The study’s authors conclude that wild boar meat research has progressed from foundational studies of carcass traits and lipid metabolism toward advanced genomic and association-based approaches, increasingly framed by nutritional evaluation and the prospect of wild game meat as a sustainable protein source. They note that collaboration networks remain concentrated within specific clusters, leaving room for broader interdisciplinary and international cooperation. Future work, they argue, should integrate multi-omics approaches with meat quality assessment, compare wild and domestic populations more systematically, and probe the nutritional implications of wild boar meat for human health. As global demand for sustainable, nutrient-rich protein intensifies, this mapping of the field’s intellectual architecture offers researchers a clear framework for where wild boar science is likely to head next.

The numbers tell a striking growth story. From a single indexed publication in 2017 and just two in 2018, annual output climbed to 17 papers in 2020, surged to 44 in 2021 and 51 in 2022, and peaked at 92 publications in 2024, the largest yearly figure in the dataset. The authors caution that the 13 records assigned to 2025 reflect only a partial year, since data retrieval ended on 23 January 2025. Overall, the corpus spans 204 sources and involves 878 authors with an average of 3.94 co-authors per paper, alongside 831 author keywords and 2,076 Keywords Plus terms. Average citation counts per document reached 11.52, with mean document age of just 2.46 years, hallmarks of a field that has grown so recently and so quickly that most of its literature has not yet reached citation maturity.

Why would anyone combine an evolutionary algorithm from the 1970s with a neural network architecture from 2014? The technical rationale, the review explains, lies in the notorious difficulty of training GANs. Adversarial models suffer from unstable convergence, hyperparameter sensitivity, generator–discriminator imbalance, and the chronic problem of mode collapse, where the generator produces only a narrow slice of possible outputs. GAs offer a gradient-free, population-based search that can explore many candidate configurations simultaneously, tolerate discontinuous and non-differentiable objective surfaces, and balance competing goals such as output quality, training stability, and computational efficiency. Where Bayesian optimization struggles with noisy, high-dimensional spaces and reinforcement-learning controllers add sequential training overhead, evolutionary search provides an alternative tuning strategy that has proved attractive for hyperparameter selection, architecture evolution, and multi-objective trade-offs.

The review’s literature synthesis identifies several landmark contributions that define the field’s methodological core. Alarsan and Younes’s GANGA framework applied genetic algorithms to GAN hyperparameter optimization and improved convergence on MNIST, while Wang and colleagues reframed adversarial training itself as an evolutionary process, mutating and selecting generator variants. On the reverse side of the convergence, He and colleagues introduced GMOEA, a GAN-driven multi-objective evolutionary algorithm that enhances convergence and diversity in high-dimensional search spaces, demonstrating that the pairing benefits optimizers as much as generators. In image translation, Xue and colleagues built AevoGAN, embedding evolutionary algorithms and channel attention into a CycleGAN architecture, and Konstantopoulou and colleagues developed GAGAN, using genetic operations to improve discriminator optimization and reduce mode collapse. Beyond imaging, Le Vine and colleagues combined conditional GANs with genetic algorithms to extract table structures from scanned documents, showing the hybrid’s utility in structured pattern recognition.

Geographically, the field is global but heavily concentrated. China dominates with 135 publications, followed by India with 47 and the United States with 30, while 47 countries contribute at least one paper. Cumulative curves show China’s steep climb from a single publication in 2018 to triple-digit totals, with India’s expansion accelerating sharply after 2021. Citation influence, however, tells a more nuanced story: China leads in total citations with 787, but Australia achieves the highest per-article average at 254 citations, and the corresponding-author analysis shows that multi-country collaboration remains modest, at roughly 5.4 percent of output. Tongji University tops institutional productivity with eight publications, ahead of MIT, Shanghai Jiao Tong University, and the University of Coimbra. Author productivity follows a classic Lotka-type distribution, with 87.24 percent of authors publishing only once, while a small recurring core sustains the field’s methodological continuity.

Thematically, keyword and co-occurrence analyses anchor the field in three intertwined strands: evolutionary optimization, adversarial generative modeling, and general deep-learning methodology. The most frequent descriptors are genetic algorithms (113 occurrences) and generative adversarial networks (111), trailed by deep learning (69), adversarial networks (48), and the recently emergent adversarial machine learning, which did not appear before 2024. Source analysis reveals moderate concentration consistent with Bradford’s law: IEEE Access leads with nine papers and Lecture Notes in Computer Science with eight, while a long tail of outlets contributes one or two documents each. The most globally cited record is a 2020 Renewable and Sustainable Energy Reviews paper on photovoltaic power forecasting with 759 citations, followed by influential works in de novo drug design, neuroscience, topology optimization, network intrusion detection, and urban design, evidence that the field’s visibility spans energy, security, biomedicine, and structural engineering alike.

The review is careful not to overstate the case for genetic algorithms. The authors emphasize that GA is not inherently superior to gradient-based tuning, Bayesian optimization, or reinforcement-learning controllers, and that its contribution is context-sensitive methodological support rather than a universal solution. Evolutionary gains often come at significant computational cost, and much of the supporting evidence rests on small-scale benchmarks, particularly classic 2D image datasets, limiting generalizability. Evaluation practice also remains inconsistent: studies variously report Fréchet Inception Distance, Learned Perceptual Image Patch Similarity, Inception Score, Peak Signal-to-Noise Ratio, and Structural Similarity Index depending on task and dataset, with no common framework for comparing quality, robustness, and efficiency across domains. This evaluation inconsistency, the authors argue, is one of the field’s most persistent structural weaknesses.

Looking forward, the scientometric evidence points to six priority directions. Scalability tops the list, since evolutionary enhancements frequently inflate computational load on already expensive models. Training stability and diversity preservation through adaptive evolutionary schemes remain unsettled. Standardized benchmarking frameworks are needed to substantiate cross-domain claims. The breadth of applications, from forecasting and cybersecurity to biomedical diagnosis and urban design, has grown faster than empirical maturity, demanding rigorous domain-specific validation with larger and more varied datasets. Interpretability and trustworthiness become critical as these systems enter healthcare and security contexts where outputs influence consequential decisions. Finally, the field’s low levels of international and interdisciplinary collaboration suggest that broader cooperation could accelerate progress where optimization, generative modeling, and domain science must intersect.

The larger significance of the study lies in its demonstration that scientometric mapping can discipline a fast-moving AI subfield. Rather than relying on anecdotal impressions of a hot topic, the review quantifies where GA–GAN research is concentrated, which themes are genuinely central, and where the literature is thin. Its portrait is one of a field with unambiguous methodological promise and genuine cross-domain reach, but one still held back by computational expense, optimization instability, uneven evaluation, and fragmented collaboration. Whether the GA–GAN convergence matures into a foundational hybrid methodology or remains a niche toolset, the new map gives researchers, funders, and practitioners a precise picture of the terrain they are entering, and a clear signal of where the next advances are most likely to come from.

The study employed two complementary computational tools to dissect this vast literature. VOSviewer, a bibliometric network software, was used to construct maps based on keyword co-occurrence, bibliographic coupling, and co-citation relationships, revealing the field’s most influential journals, authors, and countries. SciMAT, a science mapping program, was then applied to track the longitudinal evolution of the field’s thematic structure across four consecutive periods: 1996–2008, 2009–2015, 2016–2020, and 2021–2024. To validate this segmentation, the team ran an exploratory piecewise linear regression on annual publication counts, comparing candidate breakpoint models with the Akaike Information Criterion, the Bayesian Information Criterion, and goodness-of-fit statistics. The optimal model identified publication-growth transitions in 2009, 2016, and 2020, closely matching the chosen intervals and providing quantitative evidence that the periodization reflects genuine shifts in research intensity rather than arbitrary divisions.

The numbers tell a dramatic story of scientific acceleration. During the formative 1996–2008 period, the field produced an average of just 3.23 publications per year, with erratic year-to-year fluctuations typical of an emerging discipline still defining its conceptual foundations. Output increased nearly twentyfold in 2009–2015, reaching 64.43 publications annually as geographic information systems, remote sensing, and spatial modelling entered the mainstream. The third period saw another surge to 307.60 publications per year, and the final interval peaked at an average of 697.50, topping out at 762 papers in 2022, which alone represented 15.8 percent of the entire dataset. This trajectory aligns temporally with landmark international initiatives, including the Millennium Ecosystem Assessment of 2005, The Economics of Ecosystems and Biodiversity in 2010, the creation of IPBES in 2012, and the adoption of the Sustainable Development Goals and the Paris Agreement in 2015, all of which elevated ecosystem services to a central position in global sustainability policy.

Keyword co-occurrence analysis, built on 88 retained author keywords connected by 1,295 links, partitioned the research landscape into seven thematic clusters. The largest, containing 32 terms, revolves around urban planning, green infrastructure, ecosystem services, and sustainability, with terms such as air pollution, urban heat island, and resilience frequently appearing together, reflecting a strong focus on how green infrastructure addresses urban environmental challenges. A second cluster of 21 terms centres on ecosystem service valuation, urbanization, and land-use change, where the prominence of China underscores that country’s outsized role in advancing valuation studies amid rapid land transformation. A third cluster is dominated by modelling frameworks, with the InVEST model emerging as the principal tool for quantifying and spatially mapping ecosystem services, while the PLUS model is primarily associated with land-use simulation and future scenario analysis. Remaining clusters cover remote sensing, geographic information systems, biodiversity conservation, ecological security patterns, and trade-off analysis, illustrating the methodological breadth of the discipline.

The co-citation structure of journals and publications reveals where the field’s intellectual roots lie. Ecological Indicators, Science of the Total Environment, and Landscape and Urban Planning stand out as the most influential sources, demonstrating that urban ecosystem service assessment is anchored at the intersection of ecological assessment, environmental sustainability, and urban planning. Among cited papers, three intellectual lineages emerge clearly: a red cluster of foundational conceptual and classification work by authors such as Rudolf de Groot, Benjamin Burkhard, and Gómez-Baggethun and Barton; a green cluster of valuation studies led by Robert Costanza and Gaodi Xie, including the landmark 1997 Nature paper valuing the world’s ecosystem services and natural capital; and a blue cluster examining urbanization, biodiversity, climate regulation, and modelling, with contributions from Jian Peng, Chunyang He, Foley, Grimm, Liu, and Nelson. Author co-citation analysis confirms three complementary research traditions, valuation and urban ecology, methodological development, and applied ecosystem management, with de Groot’s presence in two clusters highlighting his cross-cutting influence.

Geographically, the field remains strikingly concentrated. Bibliographic coupling at the country level, restricted to nations with at least 50 publications, identifies China, the United States, Germany, Italy, and England as the network’s centre of gravity, sharing overlapping cited literatures and conceptual foundations. Countries such as Brazil, India, Iran, and Mexico show substantial connections, indicating that research has expanded beyond traditionally dominant scientific communities, yet many countries, particularly across Africa, remain barely represented. The study’s authors flag this as a critical knowledge gap, noting that Africa is projected to experience the world’s fastest urban growth by 2050, precisely the regions where ecosystem service assessments are likely to become most essential for planning and policy.

The thematic evolution analysis is perhaps the study’s most revealing contribution. In the earliest period, conservation stood alone as the field’s motor theme, exhibiting high centrality and density and linking to nascent concepts like ecosystem services, resilience, land-use change, and sustainability. By 2009–2015, ecosystem services, their values, carbon storage and sequestration, urban planning, and landscape metrics had become motor themes, coinciding with the integration of GIS, LiDAR, and participatory planning. The 2016–2020 period brought diversification and operational maturity: land-use and land-cover change rose to prominence, blue-green infrastructure expanded from a conservation focus to a multifunctional approach addressing stormwater, economics, and spatial planning, and cultural ecosystem services entered the vocabulary. In the final period, ecosystem services itself surpassed land-use change as the most influential theme, absorbing earlier topics as sub-themes, while ecological risk evolved into a dominant focus treating whole ecosystems as integrated risk receptors, and valuation shifted from static assessments toward dynamic, coupled frameworks incorporating coupling-coordination models and bivariate spatial correlation.

An overlay analysis of keyword stability across periods shows a stability index climbing from 0.21 to 0.86, demonstrating that an increasing share of the field’s vocabulary persists across successive eras even as new terms continually appear. Rather than fragmenting, the field has consolidated while diversifying, with themes branching and recombining rather than replacing one another. Concepts have evolved in recognisable lineages: urban heat island research matured into ecosystem-based cooling service assessment, carbon storage studies expanded into blue-green infrastructure and nature-based solutions, and cultural ecosystem services progressed from descriptive valuation toward planning-oriented decision support. Yet the authors caution that diversification has been driven primarily by methodological innovation rather than fundamentally new conceptual domains, and that biophysical and environmental themes remain disproportionately dominant across all four periods.

This imbalance defines the field’s most pressing frontier. Socio-economic inequalities, governance dynamics, institutional frameworks, stakeholder behaviour, and environmental justice remain comparatively underexplored, even as themes like public participation and decision-making have gained some traction in recent years. The study also acknowledges its own limitations: the analysis covered only English-language articles in a single database, relied on author keywords rather than full text, and produced bibliometric linkages that represent scholarly association rather than causal relationships. The authors argue that future progress will depend on integrating grey literature from municipalities and planning agencies, expanding research in the rapidly urbanizing Global South, and embedding ecological, social, economic, and governance dimensions within holistic frameworks. For a discipline that has grown from three papers a year to more than 700, the next challenge is not measuring what nature gives cities, but ensuring that those measurements serve everyone who lives in them.

The research, conducted by Steve Jankowski of the Media Studies Department at the University of Amsterdam and published in the journal AI & Society, takes an unusual methodological approach to this problem. Rather than conducting a conventional systematic literature review, Jankowski performed a bibliometric science mapping of the most popularly cited research about Wikipedia and other Wikimedia projects between 2005 and 2025. Starting from 524 documents collected through Google Scholar, the study purposively sampled 70 of the most heavily cited works and subjected them to a reflexive thematic analysis, a qualitative technique in which themes are defined by conceptual coherence rather than statistical clustering. The goal was to excavate the intellectual lineages that have shaped how scholars understand Wikimedia projects and to identify the epistemic boundaries that keep the field divided.

The analysis surfaced seven recurring matters of concern that have animated two decades of Wikimedia scholarship. These include the status of Wikipedia as digital property or commons, the development of corporate AI software from Wikipedia content, the social and cultural consequences of social media platforms, the optimization of human-computer interaction systems, the shifting cultural significance of the encyclopedia, Wikipedia’s reliability as an information source, and the sociotechnical governance of distributed authority. Jankowski organizes these concerns into three magnitudes of citation impact, described as major, minor, and diminished, and traces how each cluster rose, plateaued, or declined across the twenty-year window.

The most heavily cited concern centers on the political economy of digital property and commons, a debate launched in the mid-2000s by Yochai Benkler’s concept of commons-based peer production in The Wealth of Networks and Don Tapscott’s market-oriented vision in Wikinomics. These foundational texts, alongside work by Clay Shirky, Lawrence Lessig, and Axel Bruns, refashioned Wikipedia from an online curiosity into a serious research object of economic innovation. Their citation curve follows what Jankowski calls a marathon pattern, peaking around 2015 but never falling below 1,500 annual citations, largely sustained by the enduring influence of Benkler’s book. Notably, these works relied on evaluative and theory-building methods, using eclectic case comparisons rather than statistical analysis to make claims about the social value of collaborative production.

The second major concern is the one with the most consequential implications for Wikipedia’s present troubles: the extraction of semantic knowledge from Wikimedia content to build corporate artificial intelligence. Jankowski traces two waves of this research. The first, exemplified by work from Yahoo! Research scientists on deriving semantic relatedness from Wikipedia, plateaued between 2013 and 2017. The second wave arrived with the 2012 launch of Wikidata, a project that converted Wikimedia content into structured knowledge graphs and received substantial funding from Microsoft co-founder Paul Allen’s Institute for Artificial Intelligence, Google, and the Gordon and Betty Moore Foundation. The study documents tight corporate entanglement throughout this research lineage, including co-authors from Facebook AI Research and Wikidata’s lead developer working as an ontologist at Google. Citation counts for this concern climbed steadily to a peak in 2021 and 2022, then dropped sharply following the release of OpenAI’s chatbot, the moment the study identifies as the beginning of Wikipedia’s AI extraction crisis.

This crisis is not merely academic. The Wikimedia Foundation has warned that large language models are trained on Wikipedia content, often weighing it more heavily than any other dataset, while answer-based interfaces reduce direct human visits to the encyclopedia. If knowledge seekers obtain Wikipedia content through chatbots and search results rather than the site itself, both readers and potential contributors become disintermediated from the community, severing the feedback loop that sustains peer production. Jankowski notes that these warnings echo concerns raised more than fifteen years ago, when scholars of peer production cautioned that packaging and distributing collaborative content disconnects it from the norms, protocols, and community structures that created it. Yet the fragmented nature of Wikimedia research has prevented these warnings from circulating as a unified debate within the field.

That fragmentation, the study argues, is rooted in deep methodological divisions. Drawing on Hans-Georg Gadamer’s philosophy of the human sciences and on science and technology studies concepts such as trading zones and boundary objects, Jankowski characterizes Wikimedia research as a fractionated trading zone: a meeting place of communities with incommensurable epistemic traditions who nonetheless organize their work around a shared object. Mapping the seven concerns by methodological composition reveals stark contrasts. Research on optimizing Wikipedia and on corporate AI software is overwhelmingly quantitative, grounded in statistical analysis and computational modeling. Research on Wikipedia’s cultural significance is almost entirely evaluative, consisting of ethnographies, histories, and cultural critiques that seek to understand how the encyclopedia came to be what it is, in line with Gadamer’s insistence that human science aims at historical understanding rather than predictive regularity.

Between these poles, the study identifies a methodological inter-language that could mediate across the divide. Three concerns, those addressing social media platforms, distributed authority, and Wikipedia as a reliable source, employ nearly equal mixtures of quantitative, qualitative, and evaluative methods. Jankowski describes these as an inter-language translation network, positions from which insights can be converted and communicated across otherwise distant research communities. For example, the gulf between scholars studying Wikipedia’s cultural meaning and engineers building AI from its content could be bridged through conversations about social media platforms and information reliability, concerns that both camps can recognize. The study also finds, through co-citation analysis, that the two most influential concerns are ironically the least cited within Wikimedia research itself: only 40 percent of citations to the digital property literature and just 24 percent of citations to the social media platforms literature come from papers with Wikipedia as a keyword, suggesting these insights circulate mainly outside the field’s core.

The historical arc that emerges from the citation curves tells a story in four waves. A first wave from 2005 to 2007 established Wikipedia as a valid research object, driven by researchers drawn to both its accessible data and its utopian promise of peer production. A second wave, beginning in 2007, theorized ownership and generated the vocabulary of commons-based peer production, wikinomics, and produsage, giving the wider world a language for a medium it did not yet know how to discuss. A third wave broke out in 2011, when machine learning and knowledge base research departed from the peer production frame and pursued semantic extraction as an end in itself. A final wave, arriving late with the mid-2010s epistemic crisis of networked propaganda, mapped the sociotechnics of social media platforms and continues to rise, now standing nearly equal in citations to the AI extraction literature.

Jankowski concludes that fragmentation need not arrest collaboration, pointing out that decentralized, contested conditions are part and parcel of Wikimedia itself. The remedy he proposes is neither another literature review nor a forced unification, but deliberate cross-disciplinary citation practices that put AI researchers and cultural scholars into direct conversation, building on a recent manifesto calling to unite and reignite critical Wikimedia research. The deeper lesson of the bibliometric history is a recursive one: the methodological choices of researchers have not merely described Wikipedia but have changed its cultural meaning and sociotechnical function, from commons to commodity to training corpus. As the encyclopedia confronts an answer-based web increasingly mediated by the very AI systems its content helped build, the study argues that understanding how we came to know Wikipedia may be the first step toward deciding what it should become.
