Introduction
Architecture, as both an academic discipline and a professional practice, is deeply rooted in the exploration of form and typology. These concepts are fundamental to the creation and critique of architectural space, offering a lens through which the physical and theoretical aspects of architecture can be understood and advanced. This research delves into the scholarly discourse surrounding architectural forms and typologies, employing a comprehensive bibliometric analysis to map the intellectual landscape of this field (Vergara-Perucich, 2021, 2023, 2024). Through meticulous examination of the existing literature, this study aims to uncover key trends, influential works, and emergent themes that define the discourse on architectural forms and typologies.
Bibliometric analyses play a crucial role in advancing knowledge across various fields. These research approaches provide insights into the evolution of scientific production, identifying trends and setting work priorities (Selva-Pareja 2022, Pinto 2019). These analyses also help in understanding the place of specific journals and their contribution to scientific literature (Adanir 2020, Erciyas 2022). Furthermore, bibliometric studies can be used to measure the depth of public awareness and the impact of social impact of scientific findings (Winardi 2022). The use of bibliometric methods is expected to grow, with the introduction of advanced technologies and new tools (Basile 2022).
The focus of this research is on the intricate dynamics of architectural knowledge as it pertains to form and typology. Researching architectural processes to generate form is crucial for several reasons. Firstly, it allows for the development of sustainable and technically sound solutions in vulnerable environments (Bernal, 2019). Secondly, it enhances the management of the design process, which is essential for the success of construction projects (Alkassabany, 2020). Thirdly, it can lead to the creation of innovative tools, such as a board game to support the design process (Deliberador, 2019). Fourthly, it can contribute to the understanding of the relationship between space, form, and process in architectural science (Hyde, 2017). Fifthly, it can drive practice and learning in architecture, leading to more diverse and iterative design research processes (Aydemir, 2022). Lastly, it can inform a research agenda that nurtures a more vibrant and sustainable built environment (Brause, 2020). In relation to typology, the literature also provides insights to value its importance in advancing knowledge. In this case, it allows for the identification and analysis of building types, which can inform architectural projects and stimulate design proposals (Pisani, 2011). Also, it can be used as a learning framework in design studios, guiding project decisions and encouraging ideation (Grover, 2018). By analyzing a vast corpus of scholarly works, this study seeks to identify the significant contributions, thematic focuses, and methodological approaches that have shaped the architectural discourse. The ultimate objective is to construct a detailed map of the intellectual terrain, highlighting both the historical evolution and contemporary developments in this area of study.
At the heart of this investigation lies the research question: How have form and typology been explored and researched within the architectural literature, and what are the prevailing trends and emergent themes that define this discourse?

Methodology
The methodological approach employed in this research was meticulous and comprehensive, designed to yield a robust dataset for a nuanced bibliometric analysis within the field of architecture. The initial phase involved the formulation of precise search criteria to navigate the expansive and multifaceted database of the Web of Science (WOS). The chosen search parameters were as follows:
wc=(“architecture”) and ts=(typology or form) NOT ts=(computer or programming) and Engineering Electrical Electronic or Computer Science Hardware Architecture or Computer Science Theory Methods or Telecommunications
The later code effectively excluded categories not pertinent to the architectural discourse. This exclusion was pivotal to ensure the relevance and specificity of the results, eliminating fields such as Geology, Computer Science Artificial Intelligence, Computer Science Information Systems, and Materials Science Paper Wood.
The rationale behind selecting WOS for this investigation was its distinct categorization for “architecture,” which significantly streamlined the search process. This categorization allowed for a more targeted retrieval of documents, ensuring that the corpus was predominantly centered around architectural studies and discourse. Many papers are wrongly indexed as architecture but in reality they refer to computers and hardware. The initial search query yielded a substantial corpus of 4726 documents. However, this dataset required rigorous refinement to ensure the integrity and utility of the data for subsequent bibliometric analysis.
The cleaning process was an essential step, addressing the issues of incomplete metadata, such as missing authors, keywords, or references. These deficiencies rendered a significant portion of the initial results unsuitable for a comprehensive bibliometric analysis, which relies heavily on the availability and accuracy of metadata to trace citation patterns, keyword co-occurrences, and authorial networks. Through this meticulous cleaning process, the dataset was refined to a more manageable and reliable sample of 3178 documents.
The cleaned dataset was then subjected to an in-depth bibliometric analysis using the bibliometrix package in R. This package was chosen for its robust capabilities in handling and analyzing large bibliometric datasets, providing a suite of tools for performing various types of analyses, including co-citation, co-authorship, and thematic mapping. The bibliometrix package facilitated a systematic examination of the architectural literature, enabling the identification of key trends, influential authors, and pivotal publications within the domain.
The analysis began with a descriptive examination of the dataset, capturing the temporal distribution of publications, the geographical dispersion of research output, and the core journals contributing to the field. This preliminary analysis provided a foundational understanding of the landscape of architectural research, highlighting the prolific periods of publication and the prominent regions and institutions driving the discourse.
Subsequently, the analysis delved into more complex bibliometric indicators, such as citation analysis and co-citation networks. Citation analysis enabled the identification of highly cited works, shedding light on seminal papers and influential authors that have shaped the architectural field. Co-citation analysis further elucidated the intellectual structure of the field by mapping the relationships between frequently co-cited papers, revealing clusters of related research and thematic concentrations.
Additionally, a keyword analysis was conducted to uncover prevalent themes and emerging topics within the architectural literature. This involved examining the frequency and co-occurrence of keywords, which provided insights into the evolving focus areas and research trends in architecture. The thematic mapping generated through this analysis highlighted the interplay between various subfields and the shifting priorities within architectural research.
The methodological rigor of this study was underscored by the comprehensive data cleaning and the sophisticated analytical techniques employed. The use of the bibliometrix package in R allowed for a detailed and multifaceted examination of the architectural literature, yielding insights that are both deep and broad. This methodological framework not only ensured the reliability and validity of the findings but also set a precedent for future bibliometric studies in architecture.
