Arash Joorabchi AS, BSc (Hons), PhD

I am a postdoctoral researcher with Dr. Hussain Mahdi in the Department of Electronic & Computer Engineering, University of Limerick, Ireland. The main focus of my current research is on developing and deploying text mining\analytics algorithms and techniques to automate the process of metadata generation in digital libraries and repositories. My major areas of interest include: Data Mining, Knowledge Organization, Text Analytics, Digital Libraries, and Linked Data.
