Study On Tourism Multimedia Active Service System

With the development of information service, the personalized active information service is obtaining increasing attentions as a new research focus and a novel information service pattern. The thesis studies the tourism multimedia active service system and the main work done of the thesis are as follows:(1)Complete the implementation scheme design of the multi-agent based system and the design of the main functional modules,including user interface agent, filtering and ordering agent, interest learning agent, monitoring agent and information searching agent, as well as the system database design.(2) Complete the establishment of user interest model,including the collection and process of user interest information, the application of K-nearest-neighbor algorithm based on vector angle (VA-KNN),the establishment and evaluation of user interest model,and the update and modification methods of user interest model.Improve the VA-KNN, and the results of comparative experiments indicate the increase of the improved VA-KNN on classifying speed and accuracy.(3)Implement the tourism multimedia active service prototype system based on JADE development platform, including the tourism multimedia active push service module, the tourism multimedia active pull service module and the tourism multimedia active advertising service module; implement system testing, and the results indicate that the system achieves good effects on the quality of active service and the accuracy of recommending and can meets the personalized requirements of tourists. The thesis implements the tourism multimedia active service system. By gathering a variety of tourism related multimedia sources and user interest information through both explicit and implicit methods,the system establishes user interest model, provides personalized tourism multimedia active service and satisfies the increasingly personalized tourism service requirements.
