Mobile app stores provide an extremely rich source of information on app descriptions, characteristics, and usage, and analyzing these data provides insights and a deeper understanding of the nature of apps. However, manual analysis of this vast amount of information on mobile apps is not a simple and straightforward task; it is costly in terms of human effort and time. Computational methods such as topic modeling can provide an efficient and satisfactory approach to mobile app information analysis. Topic modeling is (...) a type of statistical modeling technique for discovering abstract topics that occur in a set of documents. This study explores the relationship between features of Arabic apps and investigates how well the current predefined Google Play app categories represent the type and genre of Arabic mobile apps. Based on the textual app description analysis, we aim to design and develop a sustainable classification system using the Latent Dirichlet Allocation method of topic modeling in order to cover the Arabic apps classification in Google Play app store. Our study supports the hypothesis that the textual app descriptions are effective in suggesting new categories for Arabic mobile apps in Google Play app store. Also, the results indicated that the current classification on Google Play app store is not suitable for our case study “Arabic apps,” as well as it is not sustainable, as it can not cover the new app types including Arabic apps. This study offers an important contribution to Arabic app analysis and design, to improve app search and exploration in several domains such as business, marketing, and technical development. Furthermore, it provides insights for the future of Arabic app research and provides guidance for the development of an Arabic app dashboard that will support users on how to select an app based on their specific needs.

In recent years, more and more mines have been left idle, and the formed mine wasteland has become a visual pollution of the urban landscape, and the study of landscape design of mine parks has become a focal topic. To address this issue, the sample of this study was selected from Xuzhou Anran Mountain Quarry Abandoned Quarry, to enhance the ecological environment and landscape value of the site through the sample's naturalistic style design and performance. The goal of the study (...) is to explore the innovative design and performance of naturalistic style in the landscape of Xuzhou abandoned quarry park. Methods of this study: observation forms, questionnaires and interview forms, relevant cases and other research methods were used to analyse the overview of mine transformation in China, the landscape characteristics, ecological status and problems of Xuzhou mine wasteland. The design strategy of naturalistic style in the landscape of Xuzhou mine park is proposed.The results of the study show that (1) mine rehabilitation. China's big cities have more mine rehabilitation, and the proportion of cases in small cities is relatively small. (2) Characteristic aspects. Abandoned mines in Xuzhou are characterised by serious ecological damage and chaotic and dilapidated site landscapes. (3) Design strategy. It should be carried out from the ecological restoration and management of the site environment, the aesthetic expression of naturalistic landscape, and the use of natural elements and natural materials. In addition, through the in-depth analysis of the sample landscape design, the originally desolate abandoned mine was transformed into a naturalistic style landscape space, adopting ecological and cultural strategies. The results of the study contribute to the ecological and economic development of the region, and also provide theoretical and practical guidance for the rehabilitation of other mines in China.

This study reviewed how oil affected Iraq's internal and foreign policies throughout contemporary history, as it sought in its goal to identify the role of oil in Iraqi politics from independence until the beginning of the twenty-first century, and to achieve the goal of the study, the descriptive analytical approach was relied on, and the historical method, in order to identify the scene of Iraqi politics and the impact of oil and its role in the political practices of the Iraqi (...) state since independence until the beginning of the twenty-first century, and the importance of the study is due to the importance of oil The first is the importance of oil in Iraq, and it has two requirements, the first is a brief summary of the history of the importance of oil in Iraq The second demand focused on the status of oil in the period following the independence of the Iraqi state..and the second section was entitled Oil crises and their repercussions on Iraqi policy, and it has two requirements, the first dealt with the crisis The first oil and its repercussions on Iraqi politics, and the second requirement dealt with the second oil crisis and its repercussions on Iraqi politics, then came the third section entitled the role of oil in the political scene of the State of Iraq, and it has two requirements, the first talked about the political situation of the State of Iraq at the beginning of the 21st century and the role of Iraqi oil in the international scene, The second and final requirement of the study focused on Iraq's political and economic landscape in the aftermath of 2003; The study also explored the role of oil in the reconstruction of the Iraqi state. It uncovered several key findings, among which the most significant are: the management of oil in Iraq is synonymous with the management of all industrialized nations. The post-2003 period brought about transformative changes, as Iraq's oil market endured severe crises. Politically, the lack of democracy and the challenges of establishing a more democratic system in Iraq can only be fully understood by considering the economic dimensions, particularly the role of oil. The study highlighted that Iraq faced significant market risks and oil price fluctuations. Additionally, the invasion of Iraq in 2003 and the subsequent period up to 2011 confirmed that historical narratives about Iraq remain deeply influential. Although there are multiple political reasons for the invasion of Iraq, all reconstruction policies and projects after the invasion also relied on the oil sector, and the study justifies that the Iraqi state cannot withdraw from the economic scene, but will be forced to adopt economic policies, However, oil remains a political and strategic commodity over which no country can cede control to non-state actors.
