Unveiling Research Trends in Semantic Modality: A Bibliometric Analysis (2005–2024)

Introduction

Semantic modality is a crucial concept in linguistics that defines how language conveys meanings associated with possibility, necessity, and capacity. This concept involves how speakers utilize language to convey varying degrees of certainty, duty, and intention, making it relevant to both theoretical and applied linguistics (Bodnaruk, 2019; Palmer, 2001; Zhang, 2019). Semantic modality is closely linked to grammatical and lexical categories such as tense and aspect, although it uniquely conveys the speaker’s perspective and attitude toward the stated proposition (Bybee, 1994; Costa & Pessotto, 2022). Thus, semantic modality is crucial not just in linguistic studies but also in several disciplines like logic, philosophy of language, sociolinguistics, and computational linguistics, with applications in sentiment analysis, machine translation, and natural language processing (NLP).

Over the past 2 decades, research on semantic modality has progressed markedly. Preliminary study focused on the discovery and analysis of modality markers in specific languages, emphasizing grammaticalization processes and their semantic distinctions (Jucker & Taavitsainen, 2010; Narrog, 2005; Pfau & Steinbach, 2006). Recent research trends have concentrated on cross-linguistic comparisons, diachronic evolution, and the cognitive underpinnings of modality expressions, enabled by technological advancements and computational approaches (Bayoudh et al., 2022; Dullieva, 2017; Tahmasebi et al., 2021). Corpus linguistics and extensive analytical techniques have enabled the delineation of modality markers’ distributions across various genres and contexts (Aarts & Meijs, 2022; Meyer, 2023; Perkins & Roe, 2024). These advancements offer new opportunities to understand broader and more dynamic patterns in modality use. Despite substantial research efforts, a comprehensive analysis of trends and patterns in this field is absent, leading to shortcomings in understanding the global landscape of semantic modality studies.

Research on semantic modality has attracted interest from other areas. In philosophy, modality pertains to epistemic and metaphysical logic, examining possibilities and requirements within the realms of reality and knowing (Elgin, 2023; Williamson, 2023). Modality analysis in education facilitates comprehension of how language influences teaching-learning processes and meaning construction in educational interactions (Lavoie & Pellerin, 2018; Von, 2024; Wan et al., 2020). In computational linguistics, the significance of semantic modality has increased due to improvements in machine learning technologies, including applications such as semantic role labelling, discourse analysis, and automated machine translation systems (Manning, 2015; Mitkov, 2022; Tsujii, 2021). Thus, enhanced understanding of semantic modality research can aid in the formulation of more effective techniques across these various domains.

Notwithstanding considerable research endeavors, a thorough examination of trends and patterns in semantic modality research from a bibliometric standpoint has yet to be undertaken. This research seeks to address this deficiency by utilizing bibliometric techniques to examine publications in this domain from 2005 to 2024. This analysis delineates research trends and advancements in semantic modality while identifying principal authors, prevailing topics, and emerging trends in worldwide literature. Despite this progress, existing reviews remain fragmented and largely descriptive, often limited to particular languages or contexts without providing a systematic global mapping. Furthermore, little attention has been paid to the interpretive dimension—how thematic clusters, author networks, and geographical patterns reflect broader theoretical or practical dynamics in the field. By integrating descriptive bibliometric evidence with interpretive analysis, this study seeks to uncover not only what the trends are, but also what they mean for the development of semantic modality research across disciplines.

This study addresses several key questions:

Literature Review

Semantics, the study of meaning in language, is a fundamental part of linguistics that examines how words, phrases, and sentences communicate meaning (Hallman, 2017; Jabbar Alsaedi, 2018; Saeed, 2015; Szabó, 2009). Semantics serves as a fundamental pillar of the discipline, complementing phonology, which analyses sound systems, and grammar, which explores the structure of words and sentences (Saeed, 2015). The principal objective of semantics is to examine the correlation between language statements and their generated meanings, revealing patterns that allow speakers to comprehend unexpected sentences by deconstructing them into known elements (Hallman, 2017; Szabó, 2009). Fundamental elements of semantics encompass linguistic meaning, which investigates the relationship between language forms and their meanings, elucidating the processes by which meaning is formed and comprehended (Slabakova, 2018; Szabó, 2009). A crucial aspect is the recognition of consistent patterns connecting forms such as words or phrases to their meanings, providing insights into how speakers comprehend new sentences (Hallman, 2017). Moreover, semantics prioritizes an objective examination of meaning, concentrating on the conventional definitions of words while diminishing subjective or context-dependent interpretations (Jabbar Alsaedi, 2018).

Semantic modality, a branch of semantics, examines how language expresses meanings associated with possibility, necessity, capacity, and intention (Bybee, 1994; Palmer, 2001). This encompasses diverse verbal phrases that convey a speaker’s attitudes, views, or assessments regarding a proposition (Kratzer, 2012). Semantic modality investigates the interplay of grammatical, lexical, and contextual components in forming intricate meanings, rendering it important in both theoretical and applied linguistics (von Fintel & Iatridou, 2008). Formal semantic methodologies facilitate an exact examination of modality through the use of formal logic frameworks to elucidate the connections between linguistic expressions and their significations (Montague, 1970). Simultaneously, the Natural Semantic Metalanguage (NSM) approach enables cross-cultural examination of modality by recognizing universal semantic primes inherent in all languages (Wierzbicka, 1996). Utilizing these theories, semantic modality offers new perspectives on the relationship between language, cognition, and technology, enhancing our comprehension of how language reflects and influences human interaction (Nuyts, 2001). Although these approaches are well established, many studies remain language-specific or theory-bound, offering limited integration with broader global or interdisciplinary perspectives

Language modality can be classified into two main types: epistemic and deontic modality. Epistemic modality pertains to a speaker’s knowledge and views, indicating their evaluation of the veracity or probability of a proposition depending on the facts at hand. Modal verbs such as “might” and “must” convey varying degrees of possibility or certainty based on the speaker’s understanding (Furey, 2017; Nugraha, 2019; Zhang, 2019). Conversely, deontic modality pertains to necessity and permission, often reflecting rules, obligations, or permissions, typically expressed through modal verbs like “should” and “must” (Nugraha, 2019; Zhang, 2019). Beyond these modal types, languages provide various expressions to articulate these concepts. Modal verbs such as “can,”“must,”“should,” and “might” are primary tools for expressing modality. Their flexibility allows them to convey different modal meanings depending on context. Additionally, adjectives and adverbs significantly contribute to expressing modality. Words like “necessary,”“possible,”“certainly,” and “probably” modify sentence meanings, reflecting varying degrees of necessity and possibility (Portner, 2023; Ramón, 2009; Traugott, 2011). Together, these linguistic tools enable nuanced communication of attitudes, beliefs, and obligations in language. However, previous literature reviews often stop at outlining these categories without critically examining how modality research evolves across disciplines, technologies, or cultural contexts.

This gap highlights the importance of moving beyond descriptive accounts toward integrative and interpretive perspectives. While corpus linguistics and computational approaches have begun to link modality with NLP and cognitive processing, there remains a lack of systematic mapping that situates these developments within the global research landscape. A bibliometric analysis, therefore, provides a means to connect fragmented findings and reveal how theoretical traditions, technological applications, and interdisciplinary studies intersect in the study of semantic modality.

Methods

This study utilized a bibliometric method to examine and delineate research trends in semantic modality from 2005 to 2024. Bibliometric analysis is a quantitative approach that systematically assesses academic literature, utilizing publication data to reveal insights into writing patterns, citation trends, author partnerships, and prevailing themes within a study domain (Hood & Wilson, 2001; Sun et al., 2021). This study employed bibliometric tools, specifically Biblioshiny and VOSviewer. VOSviewer is a specialized application intended for visualizing bibliographic networks, encompassing author collaborations, co-citations, and keyword linkages (McAllister et al., 2022; Van Eck & Waltman, 2010). Biblioshiny is particularly effective for analyzing research patterns and topics because of its dynamic grouping and data visualization features (Aria & Cuccurullo, 2017). These tools were selected over alternatives such as CiteSpace because they provide stronger visualization capabilities and are widely validated in bibliometric studies, thereby enhancing replicability and transparency of results.

Data Collection

The primary data source for this analysis was the Scopus database, chosen for its extensive coverage of high-quality peer-reviewed academic publications. Scopus is among the largest and most reliable databases, providing comprehensive metadata on scholarly articles. Scopus was preferred to Web of Science (WoS) because it offers broader coverage in the humanities and social sciences, which are central to semantic modality research, while still maintaining rigorous indexing standards. The search was conducted on December 9, 2024, using the following query:

(TITLE-ABS-KEY ((semantic OR semantics) AND (modality OR modalities) AND (language OR linguistics)) AND PUBYEAR > 2004 AND PUBYEAR < 2025)

This query targeted articles published between 2005 and 2024, yielding a total of 3,025 articles. The metadata collected included titles, abstracts, keywords, publication years, journal names, authors, and citation counts. Irrelevant or duplicate articles were further filtered during the preprocessing stage. To ensure reliability, two independent researchers cross-checked the dataset at the filtering stage, and inclusion criteria were explicitly documented to enhance consistency.

Data Preprocessing

Subsequent to data collection, the initial phase involved preprocessing to guarantee the quality and pertinence of the information for analysis. At this stage, duplicate entries were eliminated, and irrelevant publications were excluded based on their titles and abstracts. Moreover, keyword standardization was executed to mitigate variability arising from the utilization of synonyms or varying word forms. To guarantee the inclusion of articles pertinent to semantic modality, those not centered on the primary subject were excluded through stringent inclusion criteria, encompassing articles authored in English or possessing English titles and abstracts, as well as those highlighting “semantic modality” as a principal theme.

Analysis Procedure

To enhance validity, the analysis was conducted in three phases: (1) descriptive mapping of general publication characteristics, (2) network analysis of authors, keywords, and countries, and (3) interpretive analysis linking bibliometric results to theoretical perspectives. Each phase was documented and archived to enable reproducibility.

General Characteristics Analysis

The initial phase of our investigation involved delineating overarching publication trends. This involved examining annual publication totals, prominent journals disseminating publications on semantic modality, and patterns of author collaboration. This sought to furnish a comprehensive summary of research dynamics in this domain over the last 20 years. Furthermore, the nations and organizations most engaged in semantic modality research were identified.

Co-Citation and Keyword Analysis

Using VOSviewer, co-citation networks were analyzed to identify the most influential authors in semantic modality research. This analysis enabled the mapping of relationships among authors contributing significantly to this field. Additionally, keyword association analysis was conducted to uncover recurring themes in semantic modality research. Keywords meeting specific frequency thresholds were retained, and this analysis aimed to reveal conceptual patterns defining this research area.

Identifying Research Themes

To understand the main topics in semantic modality research, frequently appearing keywords were grouped into thematic clusters. These clusters were created based on semantic relationships among keywords and their relevance to semantic modality. Trend topics helped identify dominant themes in the literature and how these themes evolved over time.

Visualization and Interpretation

Upon concluding the investigation, bibliometric maps illustrating keyword associations and theme clusters were generated utilizing Biblioshiny and VOSviewer. These maps were utilized to investigate emerging trends and delineate the progression of principal study domains in semantic modality. The visualizations provide insights into prospective study trajectories and avenues for additional investigation. Interpretive notes were added to highlight how observed bibliometric patterns (e.g., keyword shifts, author clusters, and country distributions) could be connected with theoretical developments in linguistics and computational research.

This bibliometric analysis sought to elucidate the evolution of semantic modality over the past 20 years. Furthermore, the findings of this investigation provided substantial insights for linguists and scholars across other fields interested in investigating modality in language and communication.

2. Topics with medium-term trends (2013–2021).

Medium-term topics reached peak popularity during the intermediate period from 2013 to 2021. For example, Processing (2013–2022), with a frequency of 1,068, became a focal point in studies of natural language processing and data processing. Terms like Words (2012–2021) and Word (2012–2022), with high frequencies, underscore the importance of research on individual and collective words in linguistic and textual analysis. Furthermore, core terms such as Semantic (2016–2023) and Semantics (2014–2023), with frequencies of 3,962 and 1,371 respectively, demonstrate that semantic modality remained a primary focus throughout this period.

3. Topics with modern trends (2017–2024).

Modern trends emerged alongside advancements in technology and new applications, particularly from 2017 to 2024. Terms such as Visual (2018–2023), Modalities (2017–2023), and Information (2017–2024) reflect a growing focus on integrating multimodalities in technological applications, including computer vision and multimedia analysis. Significant increases in frequency are observed for terms like Image (2021–2024) and Text (2021–2024), with frequencies of 1,264 and 1,249 respectively, indicating intensive research on text- and image-based data. Models (2021–2024), with a frequency of 1,233, underscores the dominance of machine learning models in modern applications. Emerging terms like Challenges, Enhance, and Clip (2022–2024) reflect the latest trends in cutting-edge technology, especially in transformer-based models like CLIP.

4. Dominance of general topics.

General topics remain dominant, as seen with terms like Language (2015–2023), which has the highest frequency of 3,978, highlighting that language remains central to all semantic modality research. Commonly used terms in academic contexts, such as Study (2014–2022), Paper (2015–2023), and Results (2015–2023), also show high frequencies, reflecting their frequent use in reporting study findings and analyses.

The analysis reveals a dominance of technological and multimodal themes, with terms like Image, Text, Models, and Visual highlighting research trends shifting toward technology-driven, cross-media applications. Additionally, there is a clear transition in research focus, where classical terms such as Priming and Springer-Verlag lost relevance after 2016, while modern terms like CLIP and Challenges gained prominence, reflecting adaptation to cutting-edge technological advancements. However, core terms like Semantic, Language, and Processing have remained relevant throughout, demonstrating that semantic modality research remains deeply rooted in linguistic and semantic foundations, even as it evolves with technological progress.

This shift from traditional to modern terminology illustrates how semantic modality research adapts to technological change while retaining its linguistic foundation, showing the field’s resilience and capacity for renewal. This evolution from classical terms such as “Priming” toward modern concepts like “CLIP” demonstrates how the field adapts to technological innovation while maintaining continuity with its linguistic origins. It indicates that semantic modality research is both resilient and responsive, capable of integrating new computational paradigms without losing sight of its foundational theoretical concerns.

Figure 3, The Thematic Map illustrates the relationships among various research themes based on two primary dimensions: Centrality and Density, which were analyzed to evaluate the relevance and development of themes within a specific field. Four main themes were identified in semantic modality research. The theme “Human” is the most relevant and mature in this research area, with high frequency, the highest centrality (.727), and the highest density (14.201), establishing it as the core and dominant theme. The theme “Multi-modal” is also significant, with a large cluster size and strong internal connections, reflecting a well-developed and important topic in research. The theme “Semantics” is highly relevant externally but remains in the stages of internal development, indicating that this is an emerging area with substantial potential. The theme “Computer Circuits” has low relevance to other themes but is well-developed within its own scope, indicating a very specific focus in certain research areas.

The thematic clustering reveals not only traditional concerns in linguistic theory (e.g., epistemic and deontic modality) but also the emergence of applied themes in computational linguistics. This transition suggests that semantic modality research is gradually broadening from purely theoretical frameworks toward data-driven and interdisciplinary applications, reflecting a dynamic evolution of the field.

Figure 4 illustrates the Author Co-Citation Map. The co-citation map depicts the interconnectedness of writers through mutual citations in scholarly works. Two groups were found from this research. Cluster 1 has authors including Chen X., He K., and Wang X., who constitute a substantial and intricately linked collective. This cluster predominantly encompasses technological research subjects, including computer vision and machine learning. Wang X. has accumulated 23,575 citations and possesses a total link strength of 962, signifying considerable significance and impact within this network. Cluster 2 is predominantly comprised of authors like Caramazza A., Lambon Ralph M. A., and Pulvermuller F. This cluster emphasizes linguistic and neuroscience research, specifically examining the connection between the brain and language. Lambon Ralph, M. A. possesses a total link strength of 6,502 and 546 citations, underscoring their significant influence in this domain.

The collaboration maps indicate that semantic modality research is characterized by regional clustering, with limited cross-regional bridges. This suggests that while research communities are productive locally, global integration of findings remains relatively modest, pointing to opportunities for stronger international collaboration.

Discussion

The results of this bibliometric analysis reveal significant dynamics in semantic modality research over the past 2 decades. Trends indicate a surge in attention to this field, particularly after 2016, marked by advancements in computational technologies such as Natural Language Processing (NLP), deep learning, and multimodality applications. The peak in publications in 2024, totaling 511 articles, reflects the high relevance of this topic across disciplines. This pattern aligns with broader shifts in corpus-based linguistics and the proliferation of AI-driven methodologies, suggesting that growth in semantic modality research is not isolated but embedded within global transformations in linguistic inquiry.

Conclusion

Research on semantic modality has significantly progressed over the last 20 years, resulting in a remarkable increase in publications peaking in 2024. This trend highlights the growing importance of semantic modality as a crucial interdisciplinary topic, driven by advancements in computing technologies such as deep learning, natural language processing, and multimodal integration. By mapping research output, author networks, and thematic clusters, this bibliometric study provides the first comprehensive overview of how the field has evolved globally, revealing both the continuity of linguistic foundations and the expansion into technological and cognitive domains.

The bibliometric analysis emphasizes phrases like Semantics, Human, and Computational Linguistics, signifying a strong basis in language and cognitive principles. Thematic maps highlight the importance of themes such as “Human” and “Semantics” for research progress, while themes like “Computer Circuits,” which show diminished relevance, suggest potential avenues for further exploration, particularly in advanced technologies like artificial intelligence and edge computing. The prominence of “Human” as a central theme underscores the inseparability of modality from human meaning-making, bridging theoretical linguistics with embodied cognition and applied AI.

This study also underscores the dominance of research in countries like China and the United States, while highlighting the discrepancy between national productivity and individual author influence. These findings point to the structural role of institutional collaboration and funding systems in shaping research visibility, while also identifying gaps in global integration. Expanding participation from regions such as Southeast Asia and Africa would not only diversify datasets but also enrich the conceptual landscape of modality studies.

This study acknowledges its limitations, including linguistic bias toward English, dataset bias, and inconsistencies between theoretical frameworks and actual applications. The challenges in model validation and multimodal integration highlight the need for further methodological breakthroughs to address the complexities of cross-modal data. Future research should therefore prioritize (1) enhancing cross-linguistic and cross-cultural representation, (2) strengthening theoretical integration between linguistic semantics and computational models, and (3) fostering international collaboration to connect currently fragmented regional hubs.

Semantic modality has become a field at the intersection of linguistics, cognition, and artificial intelligence. This study contributes by offering a global bibliometric perspective that not only documents trends but also interprets their significance. By doing so, it provides a foundation for future interdisciplinary research and practical applications that will deepen our understanding of meaning, language, and human communication in an increasingly digital world.
