Thereby, the study also analyses the reorientation effects away from other topics that receive less attention due to the high focus on the COVID-19 pandemic. The study aims to examine what can be learned from the (failing) interdisciplinarity of coronavirus research and its displacing effects for managing potential similar crises at the scientific level. To explore our research questions, we run several analyses by using the COVID-19++ dataset, which contains scholarly publications, preprints from the field of life sciences, and their referenced literature including publications from a broad scientific spectrum. Our results show the high impact and topic-wise adoption of research related to the COVID-19 crisis. Based on the similarity analysis of scientific topics, which is grounded on the concept embedding learning in the graph-structured bibliographic data, we measured the degree of interdisciplinarity of COVID-19 research in 2020. Our findings reveal a low degree of research interdisciplinarity. The publications’ reference analysis indicates the major role of clinical medicine, but also the growing importance of psychiatry and social sciences in COVID-19 research. A social network analysis shows that the authors’ high degree of centrality significantly increases her or his degree of interdisciplinarity.</p>","PeriodicalId":21755,"journal":{"name":"Scientometrics","volume":"44 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These measurements may be targeted at individuals, institutions, journals, countries etc. Institutional level assessment is one such area that has always been and will remain a key challenge to a multitude of stakeholders. Various international rankings as well as different bibliometric indicators have been explored in the context of institutional assessments, though each of them has certain criticisms associated. Most of the existing indicators, including <i>h</i>-type indicators, mainly focus on research output and/ or citations to the research output. They do not reveal the expertise of institutions in different subject areas, which is crucial to know the research portfolio of an institution. Recently, a set of expertise measures such as <i>x</i> and <i>x(g)</i> indices were introduced to determine the expertise of institutions with respect to a specific discipline/field considering strengths in different finer level thematic areas of that discipline/field. In this work, an adaptation of the <i>x</i>-index, namely the <span>(x_{d})</span>-index is proposed to determine the overall scholarly expertise of an institution considering its publication pattern and strength in different coarse thematic areas. This indicator helps to identify the core expertise areas and the diversity of the research portfolio of the institution. Further, two variants of the indicator, namely field normalized indicator or <span>(x_{d})</span> (FN)-index and fractional indicator <span>(x_{d} left( f right))</span>-index are also introduced to address the effect of field bias and collaborations on the computation of the expertise diversity. The framework can determine the most suitable version of the indicator to use for research portfolio management with the help of correlation analysis. These indicators and the associated framework are demonstrated on a dataset of 136 institutions. Upon rank correlation analysis, no significant difference is noticed between <span>(x_{d})</span> and its variants computed using different publication counting, in this particular dataset, making <span>(x_{d})</span> the most suitable indicator in this case. The possibilities offered by the framework for effective management of the research portfolio of an institution by expanding its diversity and its ability to aid national level policymakers for the effective management of scholarly ecosystem of the country is discussed.</p>","PeriodicalId":21755,"journal":{"name":"Scientometrics","volume":"31 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A particular focus is on the strategic analysis of Spanish universities within the international panorama. Data collected from the widely known and frequently consulted Academic Ranking of World Universities are used to which clustering techniques are applied. To do so, indicators are defined that are related with university presence (in both absolute and relative terms), university performance within a specialist field with respect to the rest of the world, and within each speciality with respect to the general level of the country. With all that information, strategic clusters of specialities were identified, and an analysis by scientific field at an aggregated level was completed. Among the results, it is worth highlighting the greater international presence of Spanish universities within the specialist clusters of Food Science &amp; Technology and Hospitality &amp; Tourism Management, and their performance below the general average with respect to all universities, except for Remote Sensing, Veterinary Science, and Civil Engineering. The research fields within which the Spanish universities showed greater competitiveness are Life Sciences and Natural Science, whereas the fields of Engineering and Social Science had the lowest presence and level of international competitiveness.

We show the exact relation between these three types, namely that each SWD network is also an SWA network and that each SWA network is also an SWMd network. Yet, having the small-world property is a phenomenon that can easily occur in the sense that most networks are small-world networks in one of the three ways.

Focusing on one specific discipline in one particular period and language area—Anglophone philosophy between 1890 and 1979—we describe a procedure to create a <i>mention index</i> by identifying, extracting, and disambiguating mentions in academic publications. Our mention index includes 1,095,765 mention links, extracted from 22,977 articles published in 12 journals. We successfully link 93% of these mentions to specific philosophers, with an estimated precision of 82% to 91%. Moreover, we integrate the mention index into a database named EDHIPHY, which includes data and metadata from multiple sources and enables multidimensional mention analyses.

Comparisons of disciplinary and diachronic changes of connectors were made in two-way multivariate analyses of variance (MANOVA), and follow-up analyses of variance (ANOVA). Major findings indicate that discipline, as compared to period, is the determinant of cohesion in HCRA titles, albeit in medium effect size. The use of Extension and Enhancement prevail HCRA titles, suggesting an exponential increase of sophistication and comprehensiveness of information in the curation and dissemination of scientific knowledge. Specifically, cohesion of HCRA titles is predominantly realized by additive, temporal, and causal connectors with sharp contrasts between soft and hard sciences, indicating longer titles with these connectors attract readers by harnessing their familiarity of disciplinary knowledge. Quantitative characterization of cohesion in HCRA titles shed light on how expert writers coherently organize titles to maximize informativeness and research impact, thereby contributing pedagogically to academic writing for English for Academic and Specific Purposes, and empirically for the research on the predictability of citation impacts.</p>","PeriodicalId":21755,"journal":{"name":"Scientometrics","volume":"45 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141865177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To efficiently gather the latest innovative concepts, it is essential to accurately recognize innovative sentences within academic articles. Although several supervised methods for classifying article sentences exist, such as citation function sentences, future work sentences, and formal citation sentences, most of these methods rely on manual annotations or rule-based matching to construct datasets, often neglecting an in-depth exploration of model performance enhancement. To address the limitations of existing research in this domain, this study introduces a semi-automatic annotation method for innovative sentences (IS) with the assistance of expert comments information and proposes a data augmentation method by SAO reconstruction to augment the training dataset. Within this paper, we compared and analyzed the effectiveness of multiple algorithms for recognizing IS within academic articles. This study utilized the full text of academic articles as the research subject and employed the semi-automatic method to annotate IS for creating the training dataset. Then, this study validated the effectiveness of the semi-automatic annotation method through manual inspection and compared it with rule-based annotation methods. Additionally, the impacts of different augmentation ratios on model performance were also explored. The empirical results reveal the following: (1) The semi-automatic annotation method proposed in this study achieves an accuracy rate of 0.87239, ensuring the validity of annotated data while reducing the manual annotation cost. (2) The SAO reconstruction for data augmentation method significantly improved the accuracy of machine learning and deep learning algorithms in the recognition of IS. (3) When the augmentation ratio in the training set was set to 50%, the trained GPT-2 model was superior to other algorithms, achieving an ACC of 0.97883 in the test set and an F1 score of 0.95505 in practical application.</p>","PeriodicalId":21755,"journal":{"name":"Scientometrics","volume":"150 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings reveal that recombinant reuse exerts a negative influence on urban digital economy development, whereas recombinant creation demonstrates a positive influence. Furthermore, this study observe that knowledge diversification plays a positive moderating role in the relationship between the two divergent types of knowledge recombination and urban digital economy development. The finding suggests that a higher degree of knowledge diversification may exacerbate the detrimental impact of recombinant reuse on urban digital economy development in cities where such activities are prevalent. Conversely, cities that prioritize recombinant creation may accrue additional benefits for digital economy growth by fostering a diverse knowledge base.
