This comprehensive and in-depth study on intelligent techniques in e-commerce offers a general introduction to case-based reasoning (CBR), e-commerce and intelligent agents. The task of using CBR is introduced by combining CBR with e-commerce and multiple agent simulation from both a mathematical, logical, and business, as well as an information-technology viewpoint. The book develops unified methods, models and architectures for multiagent e-commerce, in particular for multiagent brokerage. The final chapter, Integration of CBR and MAS in e-commerce, ties all the threads together. The material is covered in an easily-accessible way aiming at researchers and practitioners, lecturers and postgraduate students of e-commerce and e-business, information technology or artificial intelligence.
