Abstract

The proliferation of Artificial Intelligence Generated Content (AIGC) poses significant challenges to user experience and information accuracy, especially on search engine websites(Guo et al., 2023). The current solution is to identify AIGC by machine learning algorithms or publicly available AI detection tools, whereas, machine learning(Wang & Wang, 2022) algorithms degrade in accuracy as more data is available and tools such as GPTZero perform poorly in the task of AIGC detection on social media. In this paper, we propose an EPCNN model to identify AIGC on search engine websites, which maintains good performance in large‐scale samples. The ERNIE model integrates cross‐domain knowledge and improves language understanding and generalization. We use ERNIE to extract text features, then use a feature pyramid network to capture semantic information at different levels, and finally use an end‐to‐end structure to connect ERNIE and the feature pyramid network to construct the EPCNN. Experimental results show that our proposed algorithm has high accuracy and the ability to handle large‐scale data compared with machine learning algorithms and AI detection tools.

36. Leader Narcissism and Employee Knowledge Management Behavior: The Roles of Employees' Trust in Management and Power Distance Orientation

Author

Zheng, Ruyi, Chen, Gary, and Li, Jie

Abstract

The current literature is becoming increasingly interested in employee management behavior. In this article, we focus on how leader narcissism affects employees' knowledge management behavior, including knowledge sharing, knowledge hiding, and knowledge manipulation. The questionnaire was administered to 260 employees in mainland China to test our hypothesis. Results showed that leader narcissism is significantly related to employee knowledge management behaviors. Specifically, leader narcissism is negatively related to employee knowledge sharing, and is positively related to employee knowledge hiding and manipulating. Employee trust in management mediates these relationships, and power distance orientation moderates the relationship between leader narcissism and employees' trust in management. Our study discusses theoretical and practical implications.
