The electronic journalism industry became one of the most important achievements of technology in the two decades. Through online media platforms, information and instant news delivered easily and cheaper than before. In addition to that, e-journalism reduces the time and space needed in traditional journalism industry, and hence improve the information lifecycle beginning from collecting reaching to delivering the news to users in convenient ways. On the other hand, Semantic Web technologies enrich the meaning of web content by converting the unstructured data to structured format. So, our proposed works aims to build robust e-journalism system based on Semantic Web technologies to improve the quality of service for journalists and readers.

Satellite images provide continuous access to observations of the Earth, making environmental monitoring more convenient for certain applications, such as tracking changes in land use and land cover (LULC). This paper is aimed to develop a prediction model for mapping LULC using multi-spectral satellite images, which were captured at a spatial resolution of 3 m by a 4-band PlanetScope satellite. The dataset used in the study includes 105 geo-referenced images categorized into 8 LULC different classes. To train this model on both raster and vector data, various machine learning strategies such as Support Vector Machines (SVMs), Decision Trees (DTs), Random Forests (RFs), Normal Bayes (NB), and Artificial Neural Networks (ANNs) were employed. A set of metrics including precision, recall, F-score, and kappa index are utilized to measure the accuracy of the model. Empirical experiments were conducted, and the results show that the ANN achieved a classification accuracy of 97.1%. To the best of our knowledge, this study represents the first attempt to monitor land changes in Egypt that were conducted on high-resolution images with 3 m of spatial resolution. This study highlights the potential of this approach for promoting sustainable land use practices and contributing to the achievement of sustainable development goals. The proposed method can also provide a reliable source for improving geographical services, such as detecting land changes.
