Samr Gamal Zanaty
A question-answering system's objective (QAS) is to provide the best response possible in any human language to a user's question. It has emerged as the way that by crawling both structured and unorganized collections of content, answers will be found in the future of internet search. Factoid question answering has been extensively studied, while answering non-factoid questions is a challenging task that examines more modern techniques of fact-finding and analysis, it can be done with a high degree of accuracy. The survey outlines the problems that were encountered in each module, how the researchers were able to fix them, as well as any benefits or drawbacks and any modifications. The survey's goal is to aid researchers in comprehending the field, as well as the many methodologies that have been used and their effects on performance.
