The precise and efficient identification of potential sleeping beauties from the massive literature can maximise their value in science and technology development. Therefore, in this study, a new time-series similarity method, called the dynamic time warping (DTW) algorithm, was designed to efficiently identify sleeping beauties. First, the top 1 % of highly cited publications (5423 publications) in the field of Artificial Intelligence (AI) between 1990 and 2010 were identified based on data collected from the Web of Science database. Then, the DTW algorithm was designed and implemented to identify potential sleeping beauties based on the benchmarking sleeping beauty citation curve. Subsequently, the DTW method was combined with three indicators defined by Van Raan (2004) to design the DTW* method. Finally, the newly designed DTW and DTW* methods were used alongside quadratic function fitting (QFF), beauty coefficient (B), and modified beauty coefficient (Bcp) to identify sleeping beauties and evaluate the effect of the DTW algorithm. Among the findings: (1) The DTW algorithm can quickly and effectively identify potential sleeping beauties with help from the citation trajectory of different benchmarking sleeping beauties. These benchmarking sleeping beauties are identified by Raan's criteria from physics, as well as the B and Bcp index from the AI field, indicating the robustness of the DTW method, which is less reliant on methods and disciplinary factors of selecting benchmarking sleeping beauties. The DTW algorithm can automatically and accurately identify different types of highly influential publications, including sleeping beauties and highly cited publications, based on publication citation trajectories, further indicating robustness and application prospects. (2) The DTW* method improves the DTW recognition accuracy using the sleeping time defined by Van Raan, to accurately identify standardised sleeping beauties conforming to the standardised citation curve of benchmarking sleeping beauty, thereby ensuring exclusion of false sleeping beauties with extremely short sleeping time. (3) Using the DTW* method, 39 sleeping beauties with sleeping time greater than five years were identified, among which, 38 met Raan's three criteria with an accuracy of 97 %. Of the 39 sleeping beauties, 62 % were conference publications, suggesting that conference publications have an extremely high probability of becoming a sleeping beauty in the AI field. In content analysis, the 39 sleeping beauties were associated with innovative algorithms, methods, and related applications. (4) The DTW algorithm can be extended to another significant different field as ‘Social Sciences, Interdisciplinary’ category for sleeping beauty identification, further verifying the effectiveness and robustness of the DTW approach.</div></div>","PeriodicalId":48662,"journal":{"name":"Journal of Informetrics","volume":"19 2","pages":"Article 101646"},"PeriodicalIF":3.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395913","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}

We present a new novelty-driven approach to measure the influence of science on patents. We overcome the weaknesses of previous methods based on either citations or semantic similarities, both representing direct linkages between documents. We combine patent novelty measurement with technology-specific, scientific dictionaries, which allow us to measure a patent's nearness to science by stable indirect linkages. We apply our indicator “science-driven novelty” to the testbed of RFID technology and confirm its validity by conducting an expert survey. Subsequently, we test how science impacts patent value, finding that scientific influence increases the average value of a patent. Our results suggest several implications. For academics, we recommend not relying solely on analyzing direct links between papers and patents to determine the influence of science on technology. For management, we provide a new tool to assess scientific influences in patents and thus the value of their company's own patent portfolio as well as the portfolios of third parties.

We tracked their patents from 2001 to 2013 and constructed a panel dataset for analysis. Using firm-location fixed effect models, we found that the average tie strength of a location's egocentric network has a negative effect on innovation radicalness, and this negative effect is stronger when the location's egocentric network is cohesive. This suggests that weak ties have informational advantages for radical innovation, which are more pronounced when there is network cohesion to mitigate the relational disadvantages of weak ties. We also found a negative effect of structural holes on innovation radicalness when tie strength is weak but a positive effect when tie strength is strong. This indicates that strong ties are needed for mobilizing the informational advantages associated with structural holes.</div></div>","PeriodicalId":48662,"journal":{"name":"Journal of Informetrics","volume":"19 1","pages":"Article 101636"},"PeriodicalIF":3.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165423","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}

In this paper, we examine the interdisciplinarity of research output driven by funding. Considering 36 major infectious diseases, we model interdisciplinarity through temporal correlation networks based on funded and unfunded research from 1995-2022. Using hierarchical clustering, we identify coherent periods of time or regimes characterised by important research topics like vaccinations or the Zika outbreak. We establish that funded research is less interdisciplinary than unfunded research, but the effect has decreased markedly over time. In terms of network growth, we find a tendency of funded research to focus on readily established connections leading to compartmentalisation and conservatism. In contrast, unfunded research tends to be exploratory and bridge distant knowledge leading to knowledge integration. Our results show that interdisciplinary research on prominent infectious diseases like HIV and tuberculosis tends to have strong bridging effects facilitating global knowledge integration in the network. At the periphery of the network, we observe the emergence of vaccination-related and Zika-related knowledge clusters, both with limited systemic impact. We further show that despite the surge in publications related to COVID-19, its systematic impact on the disease network remains relatively low. Overall, this research provides a generalisable framework to examine the impact of funding in interdisciplinary knowledge creation. It can assist in priority setting, for example with horizon scanning for new and emerging threats to health, such as pandemic planning. Policymakers, funding agencies, and research institutions should consider revamping evaluation systems to reward interdisciplinary work and implement mechanisms that promote and support intelligent risk-taking.</div></div>","PeriodicalId":48662,"journal":{"name":"Journal of Informetrics","volume":"19 1","pages":"Article 101634"},"PeriodicalIF":3.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165372","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}
