COVID-19 pandemic has created havoc around the globe and affected face-to-face teaching. Due to which universities have adopted online learning systems to facilitate students' learning. This study ...aims to assess the impact of internal and external factors that affect students' intention to use Web 3.0. Perceived enjoyment (PE), facilitating conditions (FC), and perceived compatibility (PC) have been integrated in the technology acceptance model (TAM) to predict students' intention to use Web 3.0 during COVID-19 pandemic. The data of 381 undergraduate and graduate students have been analysed with the PLS-SEM. Findings depict that PE and FC have direct and indirect effect on students' intention to use Web 3.0 while the PC has an indirect effect on intention to use Web 3.0. This study contributes to the literature of TAM and urges that the internal motivation of students is essentially related to the use of Web 3.0 technology during the COVID-19 pandemic.
Current internet research has been influenced by application developers and computer engineers who see the development of the Web as being divided into three different stages: Web 1.0, Web 2.0 and ...Web 3.0. This article will argue that this understanding – although important when analysing the political economy of the Web – can have serious limitations when applied to everyday contexts and the lived experience of technologies. Drawing from the context of the Italian student movement, we show that the division between Web 1.0, Web 2.0 and Web 3.0 is often deconstructed by activists’ media practices. Therefore, we highlight the importance of developing an approach that – by focusing on practice – draws attention to the interplay between Web platforms rather than their transition. This approach, we believe, is essential to the understanding of the complex relationship between Web developments, human negotiations and everyday social contexts.
What can happen if we combine the best ideas from the Social Web and Semantic Web? The Social Web is an ecosystem of participation, where value is created by the aggregation of many individual user ...contributions. The Semantic Web is an ecosystem of data, where value is created by the integration of structured data from many sources. What applications can best synthesize the strengths of these two approaches, to create a new level of value that is both rich with human participation and powered by well-structured information? This paper proposes a class of applications called collective knowledge systems, which unlock the “collective intelligence” of the Social Web with knowledge representation and reasoning techniques of the Semantic Web.
Bibliotheken stellen bereits seit einigen Jahren ihre bibliografischen Metadaten als Linked Open Data zur Verfügung. Die Idee dahinter ist, Daten aus verschiedenen Quellen und Formaten (Datensilos), ...die derzeit nicht oder nur schwer zugänglich sind, in möglichst einheitlicher Form miteinander zu verknüpfen. Dieser Artikel fasst die aktuellen Entwicklungen zusammen und es werden die vier grundlegenden Möglichkeiten, Linked Open Data zu veröffentlichen, miteinander verglichen. Abschließend werden die Initiativen der Österreichischen Nationalbibliothek auf diesem Gebiet vorgestellt.
Corruption and lack of transparency remain critical challenges in governance systems around the world. These issues are often perpetuated by centralized systems and their manipulation by system ...administrators. Furthermore, the lack of data ownership and the monetization of user data by tech companies further increase concerns about transparency. In light of these concerns, this study aims to review existing blockchain-based governance models and identify best-practice governance models focusing on corruption transparency, their characteristics, and components. The research will also examine the role of a token economy in addressing trusted third-party issues related to asset ownership management. Furthermore, we discuss the effect of smart contracts, blockchain, decentralized autonomous organizations (DAOs), Web 3.0, and multifactor challenge set self-sovereign identity authentication (MFSSIA) as modern technologies to combat corruption and achieve transparency in the public sector. To achieve this, we conducted a systematic literature review (SLR) comprising peer-reviewed journals, proceedings, and book chapters published between 2012 and 2023. Using the SLR methodology, 45 primary and supporting studies have been selected for result extraction and analysis. Finally, we discovered seven blockchain-based governance models with their characteristics and primary components.
Cigarette filters are one of the most littered objects in the world that damage the environment. Incorporation in construction bricks offers the prospect of limiting damage and solves the ...recyclability problem for a typical non-biodegradable waste. This paper aims to explore that prospect, by adding cigarette filters in the production of two samples of fired clay bricks with the cigarette filters comprising 5% and 10% of the volume. The mixing and molding processes were done manually which had an effect on the bricks when tested, The results of testing were corresponding with those of previous studies (outside Egypt), however, only one sample of 5% Cigarette butts volume bricks complied with the Egyptian standards for bricks used in non-load bearing uses. The industrial production of these bricks is highly recommended as it will surpass the required Egyptian standards, save a significant amount of natural resources and eliminate cigarette waste.
The emergence of social media platforms as the main representatives of Web 3.0 applications significantly impacts the co-creation activities among enterprises, customers, and other stakeholders, and ...has enabled firms to benefit from creativity and ideas of their users and customers for developing and rendering innovative services. This study aims to investigate how the co-creation activities of users on social media platforms have an effect on the enterprises’ innovative services. For this purpose, the authors surveyed customers of innovative services who used social media platforms to meet their needs from the enterprises that innovatively offer such services. An online questionnaire was designed and distributed among the sample of customers, and 505 completed questionnaires were analyzed following the PLS-SEM approach. The findings revealed that customer citizenship behavior and customer participation behavior on social media platforms positively affect the rendering of innovative services. Findings also highlighted that an increase in social co-creation activities, as moderator, positively affects customer citizenship behavior on service innovativeness, and negatively affects customer participation behavior on service innovativeness. The findings of this research could be useful for entrepreneurs and managers of the enterprises that offer innovative services to efficiently use social media tools to benefit from the customers’ co-creation activities and to perform more competitively and sustainably in a hostile business environment.
Web 3.0 is the highly anticipated new evolution of the World Wide Web that promises greater decentralization, intelligence, and security than its predecessors. Neural networks are a powerful tool ...that can be used to build more intelligent and personalized web. However, traditional centralized learning of neural networks is limited, and the emerging cooperative learning methods such as federated learning are often restricted to horizontally partitioned data. To enable vertical cooperative learning and tackle the associated privacy preservation issues, we propose SecureSL, a vertical cooperative learning scheme based on split learning. We present an edge-end cooperative learning framework that fits the decentralized feature of Web 3.0. We adopt multi-key homomorphic encryption (MKHE) to ensure the confidentiality of the data, the labels and the trained model, making SecureSL resistant to collusion attacks. Furthermore, we employ the single instruction, multiple data (SIMD) technique and optimize the training process to improve the computational efficiency of MKHE. Finally, we evaluate the privacy preservation performance and the model accuracy of SecureSL through extensive experiments. The results show that our proposed scheme provides a robust solution for vertical cooperative learning in Web 3.0 applications which can address the critical privacy concerns while maintaining the model accuracy.
Web 3.0 is a promising next-generation Internet paradigm that is driven by multiple technologies, e.g., semantic communications, besides blockchain to enable transparent and traceable data sharing. ...Specifically, semantic communication can provide Web 3.0 services with a promising and lightweight paradigm for semantic information transmission. However, a unified integration framework has not been studied. Moreover, how to achieve efficient semantic sharing and pricing challenges the traditional centralized communication paradigm. Therefore, this paper integrates blockchain and semantic communication to share valuable semantic information for Web 3.0 services. The Proof of Semantic mechanism is designed to reduce the garbage-in garbage-out challenge of Web 3.0 services. Moreover, we utilize the state channel and the information bottleneck to construct a task-relevant semantic sharing mechanism to exchange information efficiently in Web 3.0 services. To maximize semantic information's utility, we propose a semantic pricing mechanism based multi-leader multi-follower Stackelberg game to circulate information in Web 3.0 services. Simulation results indicate that the proposed mechanisms are both verifiable and efficient, achieving reduced communication overheads while maintaining test accuracy comparable to benchmark methods.
