International Journal of Human-Computer Interaction 2026 Journal
Existing dissertation impact evaluation indexes have limitations, which make it difficult to comprehensively and accurately assess the contribution of research achievements, to solve this problem, this paper aims to construct a dissertation impact evaluation model that integrates academic and social dimensions This paper constructs an impact evaluation model from both academic and social dimensions. In the academic dimension, citation is weighted by integrating influential factors such as citation position, citation sentiment, citation relevance and temporal heterogeneity to construct the academic impact index. In the social dimension, the indicators are selected from five aspects: use, access, mention, social media and citation to construct the social impact evaluation framework The empirical analysis shows that the paper impact evaluation model constructed in this paper can more comprehensively and accurately assess the impact of papers and identify high-impact papers. The sensitivity analysis of the weights and the comparative analysis found that the model has good robustness and effectiveness. This paper proposes a new method for evaluating academic papers that integrates academic impact and social impact, which can reflect the dual impact of papers in the academic and social fields, thereby more effectively identifying high-impact papers.Tracking technology evolution paths is crucial for understanding innovation dynamics. However, current studies frequently only use text-based methods, which limit their capacity to capture the structural linkages found in technology knowledge. To address this gap, this study proposes an integrated framework that combines text embedding and network embedding to analyze technology evolution paths. Using a dataset of 35983 patents in the battery electric vehicle (BEV) domain, we extract high-dimensional semantic features from patent texts while simultaneously capturing structural relationships between patents by constructing a heterogeneous information network. By fusing these two embeddings, we construct technology evolution paths based on cosine similarity measures. The proposed method effectively reveals knowledge diffusion patterns and emerging technology trends. In addition, through pair sample t-test and topic coherence analysis, we found that the proposed method identifies more comprehensive technology evolution trajectories.

2025 Information Resource Management Annual Conference 2025 Conference
Generative artificial intelligence (GenAI) technology may pose significant security risks to academic research, including potential threats such as data privacy breaches, unfair evaluations caused by algorithmic bias, and fraudulent academic outputs. Building upon this risk prevention foundation, this study constructs an intelligent review mechanism centered on GenAI technology, aiming to effectively address the growing challenge of academic misconduct through dual pathways of standardization and efficiency enhancement, while achieving precise pre-assessment of academic quality. Based on the modular deconstruction principle of ‘Problem-Task-Technology’, this study designs an academic risk governance framework that covers the regulation and efficiency improvement path as well as the quality evaluation framework. The GenAI -driven academic risk governance framework, on one hand, addresses academic misconduct through normative verification, misconduct content screening, evaluation expert recommendation and review process feedback. On the other hand, it achieves academic quality evaluation by extracting content value, conducting multi-dimensional innovation evaluation, and locating contribution trends, thereby comprehensively enhancing governance efficiency. The governance of academic misconduct and process design aim to directly improve intelligent evaluation effectiveness, while academic quality evaluation provides a reference benchmark for expert review. The synergistic effect of them effectively promotes the practical implementation of the academic risk governance framework.

Detecting technology opportunities appropriate for enterprise R&D: The synthesis analysis of industrial technical windows and enterprise competition relations
Bo Xiang, Zhuoya Pan, Dejian Yu†, Wenjin Zuo(† corresponding author)
Technology in Society 2025 Journal
Technological opportunities (TOs) are the potential and set of possibilities for technology advances in a given industry. When enterprises are able to catch and adapt to them in a timely manner, they can grab market share from competitors who have failed to adapt to these challenges. However, when there exist large gaps between enterprises and their competitors, it should be carefully evaluated whether enterprise-specific TOs are worth exploring. Moreover, faced with diversified competitive relations, enterprises also need to formulate differentiated research and development (R&D) strategies for different TOs. To address these research gaps, this paper argues for the theoretical concepts of technical windows (TWs), emerging technologies (ETs), and TOs, and proposes a three-stage framework to detect enterprise-specific TOs.

Dejian Yu, Bo Xiang†(† corresponding author)
Electronic Markets 2025 Journal
The cross-border e-commerce (CBEC) industry plays a crucial role in the transformation of foreign trade and the upgrading of innovative development, driven by information technology and international trade policies. However, the distinctive operational pattern of CBEC enterprises necessitates the customization of the corporate credit evaluation framework to their specific features, which is absent in the existing studies. This paper proposes an integrated decision framework that incorporates multi-source features and machine learning algorithms to achieve customized credit evaluation for CBEC enterprises.

Journal of Information Resources Management 2025 Journal
It is the important issue to promote the value realization of data elements through clarifying the multiple stakeholders and multi-source heterogeneous data of scientific and technological knowledge, and their synergistic mechanism, as well as delineating the knowledge extraction paths empowered with big data and intelligent technology. Based on the process of data-to-wisdom derivation in the DIKW chain, a synergistic framework of scientific and technological knowledge involving multiple stakeholders, such as universities, research institutes, enterprises, government and the public, has been constructed, covering multi-source data such as papers, patents, products, policies and user-generated content. Then, the front-end and back-end structures of scientific and technological knowledge extraction paths are expanded, as well as the knowledge extraction outcomes and their diverse service scenarios under intelligent strategy combination patterns are explored.

Dejian Yu, Bo Xiang†(† corresponding author)
Journal of Informetrics 2024 Journal
Existing studies on the detection of emerging scientific topics (ESTs) overemphasize the newness and neglect content innovation of knowledge. Moreover, they also ignore the lag existing in knowledge diffusion. In this paper, we propose a four-stage detection framework for ESTs that maps emerging attributes from paper entities to scientific topics.

Expert Systems with Applications 2023 Journal
Artificial Intelligence (AI) has affected all aspects of social life in recent years. This study reviews 177,204 documents published in 25 journals and 16 conferences in the AI research from 1990 to 2021, and applies the Latent Dirichlet allocation (LDA) model to extract the 40 topics from the abstracts. This study aggregates the results of the LDA model from the perspectives of year, publication source, and country/region. The aggregated result is the topic distribution from different perspectives. Analysis of the aggregated results reveals the research characteristics of different publication sources (countries/regions) in the AI research, and which publication sources (countries/regions) have similar research content. These results provide help for scholars and research institutions to choose research directions, and new entrants to understand the dynamics of the field.
