Prior approaches to identifying disruptive technologies based on the accumulation of paper citations are characterized by their limited prospective and time-consuming nature. Moreover, the total citation count fails to capture the intricate network of citations associated with the focal papers. Consequently, we advocate for the utilization of the disruption index instead of depending on citation counts. Particularly, we devise a novel neural network, called Soft Prompt-aware Shared BERT (<strong>SPS-BERT</strong>), to predict the potential technological disruption index of immediately published papers. It incorporates separate soft prompts to enable BERT examining comparative details within a paper's abstract and its references. Additionally, a tailored attention mechanism is employed to intensify the semantic comparison. Based on the enhanced representation derived from BERT, we utilize a linear layer to estimate potential disruption index. Experimental results demonstrate that SPS-BERT outperforms existing state-of-the-art methods in predicting five-year disruption index across the DBLP and PubMed datasets. Additionally, we conduct an evaluation of our model to predict the ten-year disruption index and five-year citation increments, demonstrating its robustness and scalability. Notably, our model's predictions of disruptive technologies, based on papers published in 2022, align with the expert assessments released by MIT, highlighting its practical significance.

Previous studies have mainly concentrated on the academic impact of funded research, yet the exploration of how research funding affects the societal visibility of research has been significantly lacking. Thus, this study addresses this gap by examining papers published by Chinese scholars and compares the effects of funding on papers’ societal visibility (measured by Altmetric Attention Scores) with those for papers' academic impact (measured by citation counts). This study reveals several interesting findings: First, research supported by funding demonstrates a lower societal visibility, albeit a higher academic impact, compared to those without funding. Second, the societal visibility of research supported by small to moderate number of funding sources is still lower than those without research funding. In contrast, a paper's academic impact is higher if it has a higher number of research funding sources. Third, the effects of funding on papers’ academic impact and societal visibility differ by funding mechanisms—having industry funding significantly increases the societal visibility of research.

This paper introduces a novel framework for assessing temporal diversity in scholarly research. Analyzing 31 million articles from the past seven decades, I revealed an increasing trend in temporal diversity, reflecting the cumulative nature of scientific knowledge. Additionally, I found that temporal diversity is negatively associated with citation impact but positively associated with disruption. These patterns are robust and consistent across different contexts. Moreover, the findings suggest that higher temporal diversity leading to greater disruption may be primarily due to the use of older references. However, the disadvantages of temporal diversity in terms of citation impact cannot be entirely explained by other factors.

Previous studies measured impact of papers using external factors such as journals, time, and authors. However, these methods overlooks context of citations, leading to problem of treating papers with same citation counts equivalently. To overcome this issue, we designed a citation network by reflecting on the spatial context in which cited papers are cited in the citing paper and measured their impact. Spatial context is defined by the specific section of the citing paper (Introduction, Method, Result, Discussion, Conclusion) where the citation appears. We collected 818 citing papers and 13,257 cited papers from 2013–2022 from Journal of Informetrics and constructed a context-reflected citation network. Further, we utilized CRITIC method and weighted PageRank algorithm for measuring section-specific weights and impact. Results obtained in this study suggest that the impact of cited papers varies significantly depending on the section context in which they appear. We use Kendall <em>τ</em> coefficient for analyzing correlation between “times cited” rankings and contextual PageRank.
