Short CV

Said Fathalla is a Ph.D. Student at the University of Bonn. Said received an M.S. degree in Computer Science from Alexandria University, Alexandria, Egypt, in 2013. In 2007-2016 he was working as Assistant Lecturer at the Department of Mathematics and Computer Science, Faculty of Science, Alexandria University, Alexandria, Egypt. He is currently pursuing the Ph.D. degree in Computer Science at Smart Data Analytics (SDA), University of Bonn, Bonn, Germany. His research focuses on Semantic Web technologies, scholarly communication, knowledge graph construction, semantic reasoning, and natural language processing. He has several conference and journal publications in the semantic web, text classification, Bioinformatics, scholarly communication, and knowledge engineering. He participated in the program committee of several conferences, such as ACM SAC, and he is a reviewer in several journals, such as IJSWIS, MDPI Publications, KIS, and TKDE.
