UML metamodel, like other metamodel change through time as a result of changing needs and technical improvements during their life cycle. Adding new update or bug fixing can change UML metamodel, so potential inconsistencies with existing models that correspond to the previous version of the UML metamodel and may become non-compliant with the new version. In this approach, the refactoring facilitates a UML metamodel refactoring in well-defined steps from the basic features. The use of this refactoring allows extending the functionality of the existing UML metamodel. This research focuses on the methods and processes involved in adapting the UML metamodel to changing needs and technical improvements over time. The study highlights the potential for inconsistencies to arise from updates and bug fixing in the UML metamodel. The research methodology used is the refactoring of the UML metamodel through a well-defined process in well-defined steps. The study found that the refactoring process allows for the extension of the basic features of the UML metamodel and the introduction of new functionalities. The research concludes that the use of well-defined refactoring processes is essential in maintaining the evolution of the UML metamodel and ensuring its compliance with changing needs and technical improvements.
The ever-accelerating growth in scientific literature presents a formidable challenge for researchers and students aiming to stay abreast of the most recent findings. Previous solutions, which include content-based, collaborative-based, and graph-based filtering recommendation systems, have their own limitations, primarily their inability to efficiently manage time-consuming search engine queries, a frequent issue for students. To address these constraints, we introduce a novel tool-a multi-agent system with an intelligent filtering mechanism. This system automates the literature search and filtering process, generating search queries independently and conducting comprehensive online searches. The system comprises autonomous agents that collectively gather and analyze data from a myriad of sources. Utilizing sophisticated techniques, the intelligent filtering mechanism leverages user preferences, interests, and contextual information. Continuous learning from user feedback allows the system to iteratively refine its recommendations, providing a personalized user experience. A user-friendly interface has been developed to streamline the configuration of the search procedure, offering users an easy way to fine-tune their preferences. Evaluations indicate that our approach delivers superior performance, significantly improving the process of scientific literature recommendation. Our tool is designed to assist researchers and students by minimizing the manual effort required in literature search and filtering, thereby ensuring efficient access to pertinent information. By automating these labor-intensive tasks, our tool enables users to keep pace with the latest scientific discoveries with increased ease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
