Research On Negotiation Support System For Electronic Commerce

In recent years, the important breakthroughs of technology of computer, network and communication increase the application and popularization of Internet in many fields, and promote the rapid development of the electronic commerce of B2B and B2C. The development of electronic commerce breaks region boundary, accelerates the commerce globalization process and increases the frequency of international commerce negotiation. However, because of factors of manpower, cost, workload, time and distance, adopting the traditional face-to-face way of negotiation becomes unrealistic, so Ec-NSS (Negotiation Support System for Electronic Commerce) becomes a very important new research field. These problems such as how to realize the long-distance commerce negotiation and how to provide the effective and immediate support to both sides have become the urgent problems that need to be solved in improving the function of electronic commerce and promoting the development of electronic commerce.At the basis of domestic and international research, this paper takes the whole process of commerce negotiation in electronic commerce as the main line, and comprehensively analyses and establishes the Ec-NSS. This paper deeply analyses and discusses the Web information collection, negotiation case retrieval and negotiation model construction these three problems. The main research contents are as the follows:Firstly, this paper introduces the research focus point----concept and scope definition of the Ec-NSS, and illustrates the solution of three problems of Web information collection, negotiation case retrieval and negotiation model construction.Secondly, this paper presents the outline of the Ec-NSS, and deeply studies the business process, architecture and function modules. At the basis of that, this paper constructs the Ec-NSS for supporting the electronic commerce negotiation to realize the comprehensive management of negotiation information, negotiation case and negotiation model etc. in electronic commerce negotiation. Thirdly, according to feature of commerce negotiation of information collection and the relative technology of information search and mining, this paper presents the useful information collection in commerce negotiation from information-sea by negotiation-subject-oriented information collection system. With seed-websites and appropriate extraction rules, this paper realizes the negotiation information collection, finally verifies it. The results prove that this method has a high recall and precision. With a less time resource consumption and a high extraction speed, this system meets the needs of a high rapidity in Web information extraction.Fourthly, according to the feature of the complex of commerce negotiation case and the combination of the qualitative and quantitative attribute, this paper presents case retrieval and matching mechanism based on improved AHP and NN algorithm. This paper adopts the improved AHP to gain case attribute weight and the semantic distance to gain similarity among attributes, then adopts NN (Nearest-Neighbor) retrieval algorithm to gain similarity between the question case and the old case. The experiment proved that this method is of higher adaptability and accuracy and is the effective way for case retrieval and matching.Fifthly, this paper constructs commerce negotiation model based on Improved Genetic Algorithm. According to the real situation in negotiation, this paper adds the influencing factors such as the negotiator's preference for the product attribute and negotiation strategy to the model to make the results of negotiation model become more consistent with the actual condition. Based on that, this paper designs the Agent-Agent communication model to solve the problem that both sides of negotiation cannot be on-line at the same time because of the differences of space and time. Finally, this model is testified to prove that it is highly accurate and effective and time-saving.At last, this paper designs a system named Usteel-EcNSS. According to the needs of the steel market in the northern part of Hangzhou, this Usteel-EcNSS applies the information collection of network negotiation and negotiation model to system and does useful researches to implication of Ec-NSS, and powerfully support the quality improvement of information collection for enterprise negotiation and across-time-and-space commerce negotiation.
