Social media is increasingly becoming a part of our daily life for communicating each other. There are various tools and applications for communication and therefore, identity theft is a common issue among users of such application. A new style of identity theft occurs when cybercriminals break into WhatsApp account, pretend as real friends and demand money or blackmail emotionally. In order to prevent from such issues, data mining can be used for text classification (TC) in analysis authorship attribution (AA) to recognize original sender of the message. Arabic is one of the most spoken languages around the world with different variants. In this research, we built a machine learning model for mining and analyzing the Arabic messages to identify the author of the messages in Saudi dialect. Many points would be addressed regarding authorship attribution mining and analysis: collect Arabic messages in the Saudi dialect, filtration of the messages' tokens. The classification would use a cross-validation technique and different machine-learning algorithms (Naïve Baye, Support Vector Machine). Results of average accuracy for Naïve Baye and Support Vector Machine have been presented and suggestions for future work have been presented.

This study aims to examine the role of social media marketing on the performance of micro-, small and medium-sized enterprises (MSMEs) during the COVID-19 pandemic. This research method uses a quantitative approach and the analytical tool used is Structural Equation Modeling (SEM) based on Partial Least Square. The sampling technique used purposive sampling and the sample in this study was MSMEs who use social media for marketing. The social media used are Facebook, Instagram, and Whatsapp. The number of samples in this study was 254 MSMEs. Data collection used online questionnaires. The research findings show that the use of social media marketing is influenced by compatibility, perceived usefulness, and perceived ease-of-use. The results of this study indicate that the use of social media for marketing has a positive effect on the performance of MSMEs, especially in increasing sales, customer relationships, productivity, and creativity. This means that the better the management of social media for marketing, the better the performance of MSMEs will be. The theoretical contribution to this research is built on the TAM and UTAUT theories and their impact on social media marketing on MSMEs in developing countries that are living through the COVID-19 pandemic.

This study examined the virtual methods of service delivery being deployed by librarians in private universities in Nigeria. The objective of the study was to analyse the virtual methods of service delivery among librarians and determine the predominant method used among the librarians. Survey research design was adopted for the study. Total enumeration technique was adopted for the study. A population of 181 librarians from 45 private universities in Southern Nigeria were involved. Data were gathered, analysed and presented using frequency counts, percentages, mean and standard deviation. The study found that librarians used different virtual methods of service delivery. Library website 157 (90%) and e-mail 132 (76.3%) were the prominent electronic media used by librarians while Facebook 59 (34%) and Whatsapp 57 (32.9%) were the predominant social media platforms applied for service delivery by librarians. Electronic media were more used for latest publications arrival, as well as library education and document delivery services while social media were more used for reference services and selective dissemination of information. In conclusion, virtual methods of service delivery were deployed by librarians in private universities for service delivery. In comparing the virtual methods, librarians used more of electronic media than social media to deliver services to their users. Therefore, electronic media were predominantly used than social media, many of the virtual methods were found to be underutilised while recommendations were proffered.

모바일 메신저는 모바일 기기를 통해 다른 사람들과 저렴한 비용으로 소통할 수 있는 장점 때문에 큰 인기를 누리고 있다. 카카오톡, 위톡, 라인, 왓츠앱 등 다양한 모바일 메신저 서비스들이 시장 주도권을 확보하고자 노력하고 있으며, 서비스 제공업체들은 사용자 충성도 향상을 통해 고객 유지율을 높이고 마케팅 비용을 줄이고자 하고 있다. 그래서 본 연구에서는 모바일 메신저 사용자들의 충성도에 영향을 미치는 선행 요인들을 살펴보고자 한다. 제공 업체들과 장기적 관계 유지를 위해, 사용자 충성도의 주요 요인으로 관계적 몰입과 사용자 만족을 고려하였다. 그리고 인지된 유용성, 인지된, 즐거움, 기업 이미지가 모바일 메신저 사용자들의 의사 결정 과정에 미치는 영향을 살펴보았다. 카카오톡 사용 경험이 있는 220명의 사용자를 대상으로 제안한 연구 모형을 PLS를 통해 검증하였다. 본 연구 분석 결과에서는 관계적 몰입과 사용자 만족은 사용자 충성도 형성의 핵심적인 역할을 하고 있음을 보였다. 또한, 기업 이미지도 사용자 만족을 통해 관계적 몰입과 사용자 충성도에 영향을 주는 것으로 밝혀졌다.
