Revisiting User Acceptance of Large Language Models: Discrepancies Between Literature-Derived Dimensions and Social Media User Perceptions
Revisiting User Acceptance of Large Language Models: Discrepancies Between Literature-Derived Dimensions and Social Media User Perceptions

Hongcheng Wei, Bo Xiang, Xihui Zheng, Jianlin Yang†(† corresponding author)

Association for Information Science and Technology 2026 Conference

With the widespread adoption of LLMs, understanding user usage behavior has become a critical issue. Existing studies, grounded in technology acceptance theory, rely on predefined surveys or experimental settings to identify influencing factors. They may fail to fully capture user concerns in real-world usage contexts, leading to discrepancies between theoretical dimensions and user perceptions. This study employs few-shot prompting to extract theoretical variables from research abstracts, identifying 25 variable clusters consolidated into five dimensions. In parallel, LLM-based text mining of Weibo user-generated content yields six dimensions (35 clusters). A systematic comparison between them is then conducted. The findings indicate that user perceptions of functional utility, performance, and cost or risk align with established variables, suggesting that technology acceptance frameworks retain explanatory power in the LLM context. However, users also emphasize interaction experience, emotional companionship, and technological ecosystem, which are underrepresented in existing models. Moreover, perceived usefulness is expressed in a context-specific manner. These results highlight the gap between theoretical dimensions and user perceptions and provide implications for extending acceptance frameworks and improving LLM system design.

SQ-DMVGNN: Decoupling asymmetric technological relationships and fusing semantic-quality representations for dynamic collaboration forecasting
SQ-DMVGNN: Decoupling asymmetric technological relationships and fusing semantic-quality representations for dynamic collaboration forecasting

Bo Xiang, Zhaoping Yan, Hongcheng Wei, Jin Shi†, Dejian Yu†(† corresponding author)

Information Processing and Management 2026 Journal

Technological collaboration has become an important means of sharing technological risks and advancing key technological breakthroughs. However, existing studies often overlook patent value heterogeneity in technology representation and insufficiently integrate multiple technological drivers of collaboration, while also lacking effective modeling of their dynamic evolution. This study proposes a Dynamic Multi-View Graph Neural Network model based on Semantic and Quality fusion (SQ-DMVGNN). A semantic-quality fusion module is designed to project applicants’ textual semantic features and multidimensional quality attributes into a unified high-dimensional vector space, thereby capturing both technological semantics and patent quality. Then, the proposed framework constructs a dynamic multi-view graph structures to systematically decouple and integrate technological similarity, complementarity, and strategic trend, while modeling their evolution across time slices. Through the proposed framework, SQ-DMVGNN more accurately captures the multidimensional technological relationships underlying collaborations driven by high-quality technological resources, thereby improving both the performance and interpretability of collaboration prediction in dynamic environments. This study selects the representative semiconductor industry as empirical data, obtaining a total of 668,790 non-duplicated invention patents. Experimental results demonstrate that integrating patent quality into technological portfolios enables a more precise differentiation of technological heterogeneity among organizations. Compared with baseline methods grounded in different principles, the proposed model generally achieves near-optimal performance across major evaluation metrics, particularly in AUC, AP, MRR, and Hits@K. Ablation studies not only validate the effectiveness of each auxiliary view, temporal module, and patent quality, but also investigate model substitutions. Moreover, our work conducts parameter sensitivity analyses across different modules, verifying the stability of technological knowledge extraction and collaboration prediction.

The technological and societal co-evolution landscape of AI medical conversational agents: An LLM-enhanced quantitative textual review
The technological and societal co-evolution landscape of AI medical conversational agents: An LLM-enhanced quantitative textual review

Bo Xiang, Zhaoping Yan, Hongcheng Wei, Jin Shi†(† corresponding author)

Expert Systems With Applications 2026 Journal

As an interdisciplinary product of artificial intelligence (AI), medical informatics, and human-computer interaction, AI medical conversational agents integrate cutting-edge technologies such as large language models (LLMs) and intelligent agents. Consequently, their application has given rise to numerous complex socio-ethical challenges. Grounded in sociotechnical system theory, this research constructs a mixed bibliometric framework integrating LLM, topic modeling, and social network analysis, which is used to explore the co-evolution landscape of technology and society in the field of AI medical conversational agents. In particular, a total of 4,649 domain-relevant bibliographic records are collected from the Web of Science and Engineering Village. Then, a hybrid architecture combining LLM-based agents and human verification is applied to data cleaning and alignment. Leveraging the language comprehension capabilities of LLMs, relevant literature is mapped into societal and technological dimensions, aligning with the sociotechnical system theory. The evaluation demonstrates that the few-shot approach yields better performance than the zero-shot approach across accuracy, precision, recall, and F1-score. Structural topic model is employed to construct a knowledge map comprising 5 main domains and 14 key research themes in the field of AI medical conversational agents. Based on the social and technical categorization of the literature, these topics are delineated into technological, societal, and neutral types. The topic correlation network reveals dense intra-category connections, whereas direct linkages between societal and technological topics are sparse, relying primarily on intermediate topics for bridging. Combining keyword-based analysis with the disciplinary classification of literature, this study unveils the intrinsic mechanism of the socio-technological co-evolution landscape. Notably, themes revolving around interactive experience and clinical utility serve as the primary bridges connecting social and technical subsystems. Overall, this study proposes a methodological framework integrating LLMs for bibliometric analysis, providing fresh insights into the critical domain of AI medical conversational agents.

Emotional comfort or technological delusion? An exploration of public perceptions and attitudes toward AI companions based on video social medias
Emotional comfort or technological delusion? An exploration of public perceptions and attitudes toward AI companions based on video social medias

Hongcheng Wei, Bo Xiang, Xihun Zheng, Jianlin Yang†(† corresponding author)

International Journal of Human-Computer Interaction 2026 Journal

AI companions, driven by artificial intelligence, are increasingly embedded in users’ daily lives via anthropomorphic and interactive conversational experiences. Although these systems can offer emotional support, they also raise concerns regarding algorithmic bias or data security. A comprehensive understanding of public perceptions is therefore essential for promoting healthy human-AI relationships. This paper investigates public perceptions of AI companions using 613 videos and 33,133 comments from two video platforms. Combining text mining and large language model-based sentiment analysis, it examines public topics and sentiment patterns regarding AI companions from multiple dimensions. Public attention surged after generative AI’s rise in 2023, with a pronounced “East-West divide” in user engagement. Discussions cover society (role substitution, family) and technology (companionship, anthropomorphism), with notable differences in the topics between men and women, and overall sentiment is positive. Moreover, personality traits also influence attitudes. By comparing these results with existing studies, it highlights how Chinese cultural contexts shape public perceptions. Drawing on diverse user-generated data from video platforms, the study offers valuable insights for the better design, marketing, and policymaking of AI companions.

A hybrid embedding method for identifying technology evolution paths of patents: The case on battery electric vehicle industry
A hybrid embedding method for identifying technology evolution paths of patents: The case on battery electric vehicle industry

Zhaoping Yan, Bo Xiang, Jin Shi†(† corresponding author)

IEEE Transactions on Engineering Management 2025 Journal

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.

Detecting technology opportunities appropriate for enterprise R&D: The synthesis analysis of industrial technical windows and enterprise competition relations
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.

An ESTs detection research based on paper entity mapping: Combining scientific text modeling and neural prophet

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.
