Problem statement: Extensive research efforts in the area of Natural Language Processing (NLP) were focused on developing reading comprehension Question Answering systems (QA) for Latin based languages such as, English, French and German. Approach: However, little effort was directed towards the development of such systems for bidirectional languages such as Arabic, Urdu and Farsi. In general, QA systems are more sophisticated and more complex than Search Engines (SE) because they seek a specific and somewhat exact answer to the query. Results: Existing Arabic QA system including the most recent described excluded one or both types of questions (How and Why) from their work because of the difficulty of handling these questions. In this study, we present a new approach and a new questionanswering system (QArabPro) for reading comprehension texts in Arabic. The overall accuracy of our system is 84%. Conclusion/Recommendations: These results are promising compared to existing systems. Our system handles all types of questions including (How and why).
During the last years, blockchain has been getting interest by both academic and professional researchers. This is primarily due to the innovative techniques in which records are effectively stored in a distributed manner. Started as a value transfer mechanism, blockchain now has several applications in a vast array of fields including healthcare, banking, and Internet of Things (IoTs). Despite the considerable amount of interest given to these fields, little is known about the possible applications of blockchain in education. Because of COVID-19 outbreak and the rise in the need of online and automated solutions in academia, this paper proposes an overview of a blockchain solution in education. This technology relies on the unique features it offers, such as decentralization, data integrity, and security. The presented solution aims to reduce the paperwork needed to perform tasks, secure the stored data, increase transparency, as well as to offer new recruitment possibilities and statistics capabilities to the current educational system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
