Computer systems help to improve human life in all sectors. One of the most important sectors that the recent systems support is the recruitment sector. Recruiters used to waste their valuable time, effort and money to reach the best candidates. The traditional recruitment process fulfills neither the recruiter needs nor the job seeker ambitions. Nowadays, companies use their website or social media to announce job vacancy whereas job seekers usually use job portal to market their abilities and skills. All these can be put on one recruitment website to improve the process for both parties. The proposed system will build an online E-recruitment system for recruiters (companies) and job seekers that will help them to interact with each other and to match their expectations. This system will be developed using Hyper Text pre-processor (PHP), Hyper Text Markup Language (HTML), Cascading Style Sheet (CSS), JQ, MySQL, and XMMAP. Moreover, the recent human computer interaction (HCI) concepts will apply to provide good user experience through simple, clear, and modern interfaces. Our E-recruitment system is directed to all graduated students from university in all programs. The system allows the recruiters (companies) to post announcement for job vacancy and to search for job seeker or about another company, and to view the applied job. For the job seeker it allows graduate student to search for job, apply for the available opportunities, upload CV, and setup his own profile. Finally, this study will help to improve the experience and break the difficulties that present in the recruitment process as well as support the human resource (HR) department in companies and other sectors. Finally, the results show the average score of 4.72 out of 5, indicating that the users are feeling enjoyable while using the application features and the system is easy to use.

Text Rank for Domain Specific Using Field Association Words

引用

Journal of Computer and Communications 2020年第11期8卷 69-79页

作者： Omnia G. El Barbary El Sayed atlam Mathematics Department Faculty of Science Tanta University Tanta Egypt College of Computer Science and Engineering Taibah University Yanbu KSA

Text Rank is a popular tool for obtaining words or phrases that are important for many Natural Language Processing (NLP) tasks. This paper presents a practical approach for Text Rank domain specific using Field Association (FA) words. We present the keyphrase separation technique not for a single document, although for a particular domain. The former builds a specific domain field. The second collects a list of ideal FA terms and compounds FA terms from the specific domain that are considered to be contender keyword phrases. Therefore, we combine two-word node weights and field tree relationships into a new approach to generate keyphrases from a particular domain. Studies using the changed approach to extract key phrases demonstrate that the latest techniques including FA terms are stronger than the others that use normal words and its precise words reach 90%.

Missing Data Imputation: A Comprehensive Review

引用

Journal of Computer and Communications 2024年第11期12卷 53-75页

作者： Majed Alwateer El-Sayed atlam Mahmoud Mohammed Abd El-Raouf Osama A. Ghoneim Ibrahim Gad Department of Computer Science College of Computer Science and Engineering Taibah University Yanbu Saudi Arabia Computer Science Department Faculty of Science Tanta University Tanta Egypt Basic and Applied Science Institute College of Engineering and Technology Arab Academy for Science and Technology (AAST) Alexandria Egypt Department of Computer Science Faculty of Computers and informatics Tanta University Tanta Egypt

Missing data presents a significant challenge in statistical analysis and machine learning, often resulting in biased outcomes and diminished efficiency. This comprehensive review investigates various imputation techniques, categorizing them into three primary approaches: deterministic methods, probabilistic models, and machine learning algorithms. Traditional techniques, including mean or mode imputation, regression imputation, and last observation carried forward, are evaluated alongside more contemporary methods such as multiple imputation, expectation-maximization, and deep learning strategies. The strengths and limitations of each approach are outlined. Key considerations for selecting appropriate methods, based on data characteristics and research objectives, are discussed. The importance of evaluating imputation’s impact on subsequent analyses is emphasized. This synthesis of recent advancements and best practices provides researchers with a robust framework for effectively handling missing data, thereby improving the reliability of empirical findings across diverse disciplines.

Spectroscopic Characterization, Molecular Modeling and DFT/TD-DFT/PCM Calculations of Novel Hydrogen-Bonded Charge Transfer Complex between Chloranilic Acid and 2-Amino-4,6-Dimethylpyridine

A charge transfer hydrogen bonded complex between the electron donor (proton acceptor) 2-amino-4,6-dimethylpyridine with the electron acceptor (proton donor) chloranilic acid has been synthesized and studied experimentally and theoretically. The stability constant recorded high values indicating the high stability of the formed complex. In chloroform, ethanol, methanol and acetonitrile were found the stoichiometric ratio 1:1. The solid complex was prepared and characterized by different spectroscopy techniques. FTIR, 1H and 13C NMR studies supported the presence of proton and charge transfers in the formed complex. Complemented with experimental results, molecular modelling using the density functional theory (DFT) calculations was carried out in the gas, chloroform and methanol phases where the existence of charge and hydrogen transfers. Finally, a good consistency between experimental and theoretical calculations was found confirming that the applied basis set is the suitable one for the system under investigation.

A New Approach of Time Series Variation Based on Power Links and Field Association Words

引用

Journal of Computer and Communications 2020年第3期8卷 72-85页

作者： Zohair S. Malki El-Sayed atlam Talal H. Noor Ahmad Reda Alzighaibi Ghada Elmarhomy Abdallah A. Mohamed College of Computer Science and Engineering Taibah University Yanbu KSA Faculty of Science Tanta University Tanta Egypt Mathematics and Computer Science Department Faculty of Science Menoufia University Menoufia Egypt Computer Engineering & Computer Science Unversity of Louisville Louisville USA

This paper has proposed a new methodology extracting stability classes of field association words depending on automatically power link analysis to enhance the precision of decision tree. In this paper, we have studied the effects of the time variation based on the frequencies of specific words called field association words that connected to documents using power link in a specific period. The stability classes have referred to the popularity of field association words based on the change of time in a given period. The new approach has evaluated by conducting experiments simulating results of 1575 files (about 5.16 MB). Based on these experiments, it has turned out that, the F-measure for ascending, stable and descending classes have achieved 93.6%, 99.8% and 75.7%, respectively. These results mean that F-measure was increasing by 12%, 4% and 34% than traditional methods because of the power link analysis.

Development and implementation of pilgrims (Hajj) Guide application to be used at Hajj season would facilitate follow-up of campaign supervisors on their campaign’s safety and location. The systems would also allow Hajj and Umrah administration to manage the crowd of the campaigns in an easy manner. In this paper, we propose Android/iPhone application that allows Hajj administration to monitor pilgrims using Quick Response Codes. Using quick response code application allows campaign supervisors and Hajj and Umrah employees to monitor pilgrims and guide them in case of getting lost. The application offers an easier and faster service than traditional approach used at Hajj season by human guidance. It is a very convenient service that would relief stresses of pilgrim’s relatives who worry about their relatives performing Hajj. The results show that the average score of our approach (QR) is 4.72 out of 5 comparing with traditional mobile applications indicating that the users are feeling enjoyable while using the new application features and the system is easy to use. Finally, the systems would assist in achieving the highest degree of pilgrims safety at Hajj season.
