Knowledge audit output helps organizations to make recommendation of KM strategy which later can be used for better managing the knowledge. This paper reviews literature on knowledge audit process with the aim to understand the process, the data gathering techniques employed and the roles of knowledge audit. It aims to report the research gaps and propose directions for future research in this domain. A comprehensive three-stage method for extracting, analyzing and reporting the literaturebased findings was applied in analyzing the literature survey. The literature survey is based on a search for the keywords "knowledge audit", "knowledge audit process", "knowledge audit output" and "knowledge audit roles", first on the ISI Web of Knowledge online database, followed by Association of information Systems basket of top journals and other reputable literatures. The paper concludes with an understanding on how knowledge audit is conducted, the data gathering techniques used and its contributions to the organization. However no literature was found on knowledge audit practices for inter-organization. Future research on how knowledge audit could be extended for interorganization is suggested at the end of the paper. However, this paper only covers literature that discussed in depth the knowledge audit process published in certain journals. Never the less, it is believed that the findings provide a valuable understanding of the current situation in this research field.

The success of organizations today relies heavily on their intellectual capital, as knowledge is a key resource for value creation. Sharing and transferring knowledge enhances its value, embedding it within an organization’s processes and boosting competitiveness. This study focuses on the Yemen public telecommunication corporation (YPTC), which has adopted a knowledge-focused management approach. This study aims to explore challenges related to knowledge transfer in Yemen’s public sector, where such research is lacking. Using a descriptive and analytical method, data were collected via a questionnaire from 200 employees, yielding a response rate of 88%. The findings indicate a high level of knowledge transfer at YPTC, with individual, organizational, and technological factors identified as significant influences. The key barriers include trust, information technology support, motivation, and social networks. © 2024 IEEE.

Designing virtual environments to support cooperation in the real world

引用

Virtual Reality 2002年第2期6.0卷 63-74页

Much of the current research in the design of virtual environments is centred on laboratory prototypes and emphasis is placed on supporting cooperation within the virtual world itself. By way of contrast, this paper places an emphasis upon the development of virtual enivronments that support cooperation within the real world. This external research focus situates virtual environments within the bricolage of material artefacts that people use in coordinating and accomplishing ordinary jobs of work. We elaborate the shift to the external environment of ordinary human jobs and users through an ethnographic study of searching for information in the library, and the design and evaluation of a prototype supporting the real world cooperation involved in getting the job of searching done. © Springer-Verlag London Ltd.

Cloud computing is an emerging developed technology and the next natural step in the evolution of on-demand information technology services and products that uses concepts of virtualization, storage, processing power, and sharing. According to various researches, access control and user authentication are the most important security concerns and challenging issues in cloud-based environments. Accordingly, this paper offers an agent-based user authentication and access control algorithm based on discretionary and role-based access control model for increasing the reliability and rate of trust in cloud computing environments. The proposed model uses a cloud-based software-as-a-service application with four main agents and a client-based user authentication application. After describing the proposed model, it has been justified and evaluated for identifying the strengths and weaknesses according to defined parameters: Performance, Security, Compatibility, and Power of Intelligence. Moreover, according to the identified limitations, appropriate details have been recommended and further research has been introduced. In overall, the theoretical analysis of the proposed model shows that designing this user authentication and access control model will increase the reliability and rate of trust in cloud computing environments as an emerging and powerful technology in various industries. © 2013 IEEE.

According to estimates, by mid-2030, there will be 8.6 billion people on the planet. The human population has been growing exponentially. There will be a rise in food production and consumption due to the massive population growth. Crop disease is the primary danger to food security, which damages agricultural goods while growing. Due to the limited availability of infrastructure, it remains challenging to recognize crop-damaging diseases in various parts of the world. Deep learning methods and computer vision technologies are used in this work to help identify agricultural illnesses. The train set is used to train the model, and the data split is used for validation. The farmer can use the app (Identifying and Resolving Crop Diseases using Deep Learning) to take pictures of the crops and examine whether or not there are any infections, proving the solution's viability. © 2024 IEEE.

Multimodal attention-driven visual question answering for Malayalam

引用

Neural Computing and Applications 2024年第24期36卷 14691-14708页

Visual question answering is a challenging task that necessitates for sophisticated reasoning over the visual elements to provide an accurate answer to a question. Majority of the state-of-the-art VQA models are only applicable to English questions. However, applications such as visual assistance and tourism necessitate the incorporation of multilingual VQA systems. This paper presents an effective deep learning framework for Malayalam visual question answering (MVQA), which can answer a specific natural language question about an image in Malayalam. As there is no available dataset in English–Malayalam VQA, a MVQA dataset was created by translating English question–answer pairs from the visual genome dataset. The paper proposes an attention-driven MVQA model on the developed dataset. The proposed MVQA model uses a deep learning-based co-attention mechanism to jointly learn the attention for images and Malayalam questions. A second-order multimodal factorized high-order pooling is used for multi modal feature fusion. Different VQA models using combinations of classical CNNs and RNNs were experimented on the developed MVQA dataset, and the performance was compared against the proposed attention-driven model. Experimental results show that the proposed attention-driven MVQA model achieves state-of-the-art results as compared to other models for MVQA on the custom Malayalam VQA dataset. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.
