Introduction
JAFexpert is a web-based Expert System (ES) to emulate functions of human experts in the domain of growing jute and allied fibre crops for obtaining fibre. It contains information on growing of jute (Corchorus olitorius L. and C. capsularis L.) and allied fibre crops such as mesta (Hibiscus cannabinus L. and H. sabdariffa L.= roselle), sunnhemp (Crotalaria juncea L.), ramie (Boehmeria nivea L.), sisal (Agave sisalana L.), and flax (Linum usitatissimum L.). It is an automated system to help farmers and extension workers to effectively manage these fibre crops. Knowledge, in the form of database containing information on fibre production, is obtained from experts, literature, e-resources, farmers and extension workers, which is then represented into a knowledge base.
