Merging a first name genderedness table derived from Wikidata with Web of Science publication data, we develop a relative distributional framework that compares first name, article, and citation distributions by both disciplinary group and author role along a continuous genderedness spectrum. The lexical structure of the corpus proves stable across author roles, while productivity diverges substantially by disciplinary group: physical sciences show a consistent masculine lean, social sciences a feminine one, with amplitude remaining stable across groups despite these directional differences. Once productivity is controlled for, citation analyses net of publication volume reveal a pervasive deficit across disciplinary groups and author roles: only unambiguously masculine names accumulate citations in excess of their publication volume, while feminine, neutral, and moderately masculine names all fall short of it. This asymmetry is strongest in the life sciences and weakest in the physical sciences except among middle authors, where the pattern reflects the gender composition of large collaborative teams rather than evaluative bias in citing behavior. Taken together, these results are consistent with the hypothesis that first name genderedness shapes citation recognition through implicit bias operating in low-deliberation evaluative contexts.</p>","PeriodicalId":48810,"journal":{"name":"Journal of the Association for Information Science and Technology","volume":"77 11","pages":"1418-1437"},"PeriodicalIF":5.1,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/asi.70115","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper offers a methodological reflection on five pilot studies conducted in preparation for a questionnaire-based investigation of information behavior among older adults with type 2 diabetes. Across hospital outpatient clinics, rural households, senior learning institutions, residential care facilities, and social media platforms, recurring tensions emerged between survey design assumptions and real-world research conditions. Rather than treating these tensions as isolated feasibility issues, the study conceptualizes them as methodological “failures” that revealed how questionnaire research operates as a situated and socially structured practice. The findings demonstrate that survey completion is shaped by environmental constraints, relational dynamics, institutional mediation, and perceptions of legitimacy. They challenge the assumption of the autonomous respondent and show that participation is trust-mediated and institutionally structured. By documenting iterative redesign across contexts, the paper advances a process-oriented account of methodological reflexivity and argues for greater transparency in reporting pilot-stage challenges. The study contributes conceptual and operational guidance for designing questionnaire-based research with aging populations and highlights the value of treating methodological failure as a productive source of knowledge in information science.</p>","PeriodicalId":48810,"journal":{"name":"Journal of the Association for Information Science and Technology","volume":"77 11","pages":"1375-1393"},"PeriodicalIF":5.1,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149206216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Citations enable readers to trace prior work, assess evidence, and situate new contributions within the existing literature. However, concerns have emerged regarding the presence of references in published papers that cannot be resolved to any identifiable source, including citations that appear structurally complete yet correspond to non-existent publications. While such problems have long been recognized in the form of citation errors and fabricated references, recent developments in automated text generation using large language models have renewed attention on the reliability of bibliographic data in academic publishing. This study addresses two research questions: Can we develop an automated, auditable tool to detect non-existent or unverifiable references in scholarly manuscripts? What is the prevalence and distribution of such unverifiable references in peer-reviewed papers at the intersection of artificial intelligence and education published since 2023? To answer these questions, we develop a reference verification pipeline that combines reference extraction with DOI/URL checks and cross-database matching, and apply it to a corpus of 3201 peer-reviewed papers (published between 2023 and 2025). We flag 69 papers (2.16%) that contain at least one reference that remains unverifiable under our protocol; such unverifiable references can mislead readers and propagate through citation chains.

Drawing on the social construction theory of scientific knowledge, we propose a dynamic construction lifecycle comprising three stages—generation, external evaluation, and impact diffusion—shaped respectively by authors, reviewers, and citers. By classifying contribution types from several textual sources, we examined their consistency and evolution in terms of both type and strength across lifecycle stages. The results reveal that authors highlight experimental and application-oriented contributions; reviewers focus on conceptual dimensions and apply stricter criteria; citers emphasize experimental and methodological aspects. Furthermore, a cognitive gap emerges between reviewers and other actors, indicating that reviewers often rely on perceived significance rather than contribution typologies. In contrast, alignment between authors and citers suggests that citation-based indicators, despite limitations, capture meaningful dimensions of scholarly recognition.

While structural indicators track scholarly attention, they offer only an indirect proxy for the reorganization of meaning. We propose a semantic geometry based on the R–P–C (references, focal publication, and citing publications) framework to quantify how a publication positions itself relative to its knowledge base and diffusion. This geometry identifies three publication types: consolidating, exploratory, and balanced. Our results show that the semantic similarity and distance between a publication's knowledge base and diffusion serve as a semantic foundation for disruption, with novelty (atypical reference combinations) acting as an antecedent disturbance that triggers a semantic rupture. This is related to team size, where small teams preserve a higher potential for exploratory departures while large collaborations systematically align with paradigmatic consolidation. Crucially, this geometry explains why citation trajectories differ; consolidating research earns rapid recognition by lowering comprehension costs, while exploratory work faces high paradigm conversion costs that result in slower, more selective diffusion. Collectively, this R–P–C framework provides a robust instrument for monitoring the dynamics of scientific paradigms.</p>","PeriodicalId":48810,"journal":{"name":"Journal of the Association for Information Science and Technology","volume":"77 10","pages":"1354-1369"},"PeriodicalIF":5.1,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149014683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a hybrid method that incrementally refines rankings by combining probabilistic topic modeling (latent dirichlet allocation [LDA]) with citation-based pennant retrieval grounded in Relevance Theory (RT), optimizing for both relevance and diversity. A unified scoring function fuses topic and citation cues, while a tunable weight parameter makes the relevance–diversity trade-off explicit and transparent. Applying this RT-guided approach to the iSearch corpus (435,000 physics papers, 3.7 million citations) across 65 queries, we evaluate relevance and diversity via degree centrality, arXiv subject categories, and maximal marginal relevance (MMR). Unlike prior methods that apply LDA or pennant retrieval separately—or depend on post-hoc diversification such as MMR—this approach integrates them directly and efficiently: LDA runs on local multi-core CPUs, and pennant retrieval operates using sparse co-citation counts. The combined technique retrieves both central and peripheral works, producing a boundary-spanning effect that broadens conceptual coverage while improving normalized discounted cumulative gain (NDCG) performance. Interactive visualizations via LuminaCite depict how researchers can fine-tune results in real time to reveal latent or interdisciplinary connections.
