EAI Endorsed Transactions on Context-aware Systems and Applications https://publications.eai.eu/index.php/casa <p>EAI Endorsed Transactions on Context-aware Systems and Applications (CASA) is a place for highly original ideas about how context-aware systems are going to shape networked computing systems of the future. Hence, it focuses on rigorous approaches and cutting-edge solutions which break new ground in dealing with the properties of context-awareness.</p> <p><strong>INDEXING</strong>: DOAJ, CrossRef, Google Scholar, ProQuest, EBSCO, CNKI, Dimensions</p> <p> </p> en-US <p>This is an open-access article distributed under the terms of the Creative Commons Attribution <a href="https://creativecommons.org/licenses/by/3.0/" target="_blank" rel="noopener">CC BY 3.0</a> license, which permits unlimited use, distribution, and reproduction in any medium so long as the original work is properly cited.</p> publications@eai.eu (EAI Publications Department) publications@eai.eu (EAI Support) Fri, 12 Jan 2024 00:00:00 +0000 OJS http://blogs.law.harvard.edu/tech/rss 60 Elevating User-Centered Design with AI: A Comprehensive Exploration using the AI-UCD Algorithm Framework https://publications.eai.eu/index.php/casa/article/view/4211 <div><p class="ICST-abstracttext"><span lang="EN-GB">This paper presents a comprehensive exploration of the synergistic relationship between User-Centered Design (UCD) and Artificial Intelligence (AI) within the context of the AI-UCD </span><span lang="EN-US">Algorithm </span><span lang="EN-GB">Framework. With the growing influence of AI in digital interfaces, the need to prioritize user needs and preferences has become paramount. The AI-UCD Framework, consisting of nine pivotal steps, acts as a structured guide for integrating AI into user interfaces while ensuring a user-centric, data-driven, and ethical approach.</span> <span lang="EN-GB">The exploration begins by highlighting the importance of understanding user needs and context through robust user research and contextual inquiry. It then delves into the process of defining AI integration objectives and brainstorming AI-enhanced solutions, emphasizing the creative aspects of UCD in tandem with AI capabilities. Subsequently, the paper discusses the critical role of designing AI-driven interfaces, from information architecture to user flow design, ensuring seamless integration of AI features.Implementation and testing of AI features are addressed, highlighting the collaboration between UI/UX designers and AI developers. The paper emphasizes the iterative nature of the framework, relying on usability testing and user feedback to drive continuous improvements. Moreover, it considers user training and assistance, a vital aspect of introducing users to AI features.The framework's data-driven aspect is covered by discussing data collection, analysis, and performance monitoring to ensure AI features are meeting objectives and KPIs. Additionally, the exploration addresses AI's role in personalization, adapting to user behavior and preferences. It recognizes the ethical dimensions of AI, promoting transparency, fairness, and accessibility.The paper then presents a five-step AI-UCD Validation Model, designed to verify the framework's effectiveness in real-world applications. These validation steps encompass user testing and feedback, data analysis, ethical audits, iterative improvements, and compliance with industry standards. Examples of how these steps work in practice are provided.</span></p></div> Waralak Vongdoiwang Siricharoien Copyright (c) 2023 EAI Endorsed Transactions on Context-aware Systems and Applications https://creativecommons.org/licenses/by/3.0/ https://publications.eai.eu/index.php/casa/article/view/4211 Fri, 15 Mar 2024 00:00:00 +0000 Integration and Recommendation System of Profiles based on Professional Social Networks https://publications.eai.eu/index.php/casa/article/view/4500 <p>The aim of our investigation is to personalize bilateral recommendation of job-related proposals based on existing professional social networks. In a context where the points of view of job seekers and employers can be contradictory, our approach consists in trying to bring the both in a best possible matching. To this end, we propose an integration system that gives a minimum of credit to the users’ data in order to facilitate the discovery of relevant proposals based on the users’ behaviors, on the characteristics of the proposals and on possible relationships. The main contribution is the proposal of an architecture for the recommendation of profiles and job offers including social and administrative factors. The particularity of our approach lies in the freedom from the recommendation problem by using metrics proven in the literature for the estimation of similarity rates. We have used these metrics as default values to appropriate data dimensions. It emerges that, the user’s behavior is exclusively responsible for the recommendations. However, the cross-analysis of randomly generated behaviors on real profiles collected on Cameroonian sites dedicated to job offers, shows the influence of the most active users. But, for requests via the search bar (interface with the script respecting the path of our architecture) the central subject remains the user. Our current work is limited by a data set that is not very representative of changing socio-economic conditions.</p> Paul Dayang, Ulriche Mbouche Bomda Copyright (c) 2023 EAI Endorsed Transactions on Context-aware Systems and Applications https://creativecommons.org/licenses/by/3.0/ https://publications.eai.eu/index.php/casa/article/view/4500 Mon, 15 Jan 2024 00:00:00 +0000 UGGNet: Bridging U-Net and VGG for Advanced Breast Cancer Diagnosis https://publications.eai.eu/index.php/casa/article/view/4681 <p>In the field of medical imaging, breast ultrasound has emerged as a crucial diagnostic tool for early detection of breast cancer. However, the accuracy of diagnosing the location of the affected area and the extent of the disease depends on the experience of the physician. In this paper, we propose a novel model called UGGNet, combining the power of the U-Net and VGG architectures to enhance the performance of breast ultrasound image analysis. The U-Net component of the model helps accurately segment the lesions, while the VGG component utilizes deep convolutional layers to extract features. The fusion of these two architectures in UGGNet aims to optimize both segmentation and feature representation, providing a comprehensive solution for accurate diagnosis in breast ultrasound images. Experimental results have demonstrated that the UGGNet model achieves a notable accuracy of 78.2\% on the "Breast Ultrasound Images Dataset."</p> Tran Cao Minh, Nguyen Kim Quoc, Phan Cong Vinh, Dang Nhu Phu, Vuong Xuan Chi, Ha Minh Tan Copyright (c) 2024 EAI Endorsed Transactions on Context-aware Systems and Applications https://creativecommons.org/licenses/by/3.0/ https://publications.eai.eu/index.php/casa/article/view/4681 Fri, 12 Jan 2024 00:00:00 +0000
