2025 A Systematic Literature Review of Bitemporal Databases: Research Trends, Challenges, and Future Directions 234

Traditional databases support data in one dimension only and, consequently, can’t keep a complete history of changes made to the state of the data over time. In contrast, the bitemporal database automatically handles both dimensions such as transaction time and valid time simultaneously. This advanced approach offers greater integrity and traceability of data. This is important in decision-making, for instance, in areas such as fraud detection, compliance with law, digital forensics, and regulation compliance. This research assesses articles obtainable from IEEE, Scopus, ProQuest, PubMed, and Web of Science up to 2025 with a systematic literature review methodology. Through the PRISMA framework, 74 primary studies were acquired from 102 relevant articles, providing a comprehensive and transparent evidential basis. Next, we performed a scientometric analysis using bibliometric tools like VOSviewer to examine citation trends, keywords, leading authors, and prominent journals. This research analyzes the temporal aspect of existing models of bitemporal systems. Also, it summarizes the strengths and weaknesses of bitemporal databases from existing studies. It examines each use case that adopted bitemporality in its research and identifies the research gaps. Finally, it reveals the new research directions for upcoming technologies like Artificial Intelligence, cloud architecture, blockchain, and improvement of bitemporal databases to detect their probable use in various domains like supply chain, healthcare, and financial. The originality of this research contributes to the existing knowledge by offering a scientometric analysis alongside a systematic literature review while also identifying critical research gaps that need to be addressed in future studies.

2025 Prediction and Analysis of Refugee Crisis News using NLP

The refugee problem is one of the most important issues worldwide which has gained tremendous media attention that has influenced public opinion in relation to displaced populations. This study investigates the application of natural language processing (NLP) to predict and analyze news articles on the refugee crisis. The refugee crisis remains an urgent humanitarian issue with over 117 million forcibly displaced people by the end of 2024. This study aims to develop an automated system to predict and analyze news articles on the refugee crisis using NLP techniques to gain better insights into migration patterns and highlight key areas for consideration. Mass migration and asylum-seeking pose major challenges for host country authorities, non-governmental organizations (NGOs) and international humanitarian organizations trying to solve the problems associated with the refugee crisis. Using news datasets from sources such as The Guardian and Kaggle, the study refined over 55,000 general category news articles to extract 6344 refugee-related articles by fine-tuning a Large Language Model (LLM), “Mistral 7b v0.3”. This study addresses existing gaps in AI applications by employing LLM to predict key themes, detect bias, and analyze media narratives on the refugee crisis. The methodology follows the CRISP-DM framework and uses pre-processing, prediction and visualization techniques. The results of this study include highlighting key refugee issues such as health, shelter, nutrition, security and women’s issues. In addition, it identifies potential gaps in the treatment of disadvantaged groups such as LGBTQ+ and disabled people. The study shows that, LLM outperforms traditional keyword searches, as three times more relevant articles were extracted through LLM. The findings of this study give significant details to strategy makers and NGOs to make more informed decisions on these important issues. Limitations, such as resource compatibility and dataset availability, affect the overall results yet the study highlights the potential of Artificial Intelligence (AI) in addressing the complexity of global crises and provides a foundation for future work in multilingual and multimedia analysis.
