Intelligent question — Answering systems: Review of research

With the development of ICT the need for automated question-answering systems is becoming increasingly important. Question-answering systems are still under development and experimentation. This paper is an overview of the research area that deals with question-answering systems; it explains the concept of question-answering systems and points out the problems that occur during their development. It also refers to a complex assessment techniques that are necessary when designing such systems. The system described is a real system and so are the test results.
