Meanwhile, tourism has attracted increasing attention as a high value-added service and a hot academic topic. However, the research on how to provide tour services based on context-aware services is in fact still at an early stage, limited to concept elaboration, service framework discussion, prototype system development etc. In this paper, we summarized the previous researches on context-aware services to establish the research foundation, put forward a way of analyzing a tour planning problem with a modified model of Traveling Salesman Problem （TSP） and Vehicle Routing Problem （VRP）, and we applied an innovated Resource Constrain Project Scheduling Problem （RCPSP） mathematical model to solve the tour planning problem based on context information. The simulation under branch and bound algoritban evaluated the validity of our solution.展开更多

The spread of the online word of mouth as a platform for the Interact highlights its great influence and importance. Especially in the online shopping, these reflect the user＇s point of view and attitude of the online comment has been an unprecedented attention. Online reviews have become an important medium for consumers to understand their products before they buy goods, making them an important channel for potential consumers to understand the quality of goods and services. There are many studies on online reviews, but the research on the brand awareness of cruise ship companies is almost negligible. This paper provides a reference for the construction of cruise ship brand awareness system, and combines Nvivo software to analyze the online commentary system, and provides a reference for further research on cruise brand, and prospects for future research.展开更多
