Research On Curve-fitting And Characteristics Of Traveling Website Information Flows' Distance Decay

Late last century, under the promotion of information science and technology, information industry has developed rapidly. The widespread application of information technology leads the humanity from the industrial society to the information society. The Internet technology's wide range application and the popularization are its important symbol. Traveling website is Internet technology's one applications in traditional profession. More and more Internet users will check information on traveling websites before the tourism trip, so traveling websites have become indispensable information windows for users. This article selects the traveling website as the object of study, take sample traveling website's visitor quantity and distance between cities visitors from and cities traveling websites locate in as a breach to study characteristics of traveling websites'information distance decay.First, using"Baidu""Yahoo!"and other search engines, take"the number of traveling website visitors"and so on as the key words, find out 10 traveling websites which have statistical data about visitors and have made related reorganization to the statistical data. This article take reorganized statistical data as the foundation of research.Next, it applies a set of two methods EXCEL data analysis and SPSS curve- simulation to analyses websites'data and makes charts. It attempts to reveal the mathematical model and characteristics of traveling website information flow distance decay.The research discovers: (1) the sample traveling website information flow lines from distance decay law; (2) the sample traveling website information flow distance decay weakens has both similarity of the traditional entity class and its new characteristic-to conform to the inverse curve model; (3) type and position factors of traveling websites have certain influence function on the traveling website information flow's distance decay; (4) the sample traveling website information flow's distance decay presents characteristics of"the right angle","the volatility property","the long-tail property","the dissociation weaken property".This thesis is composed of five parts:The first part is the introduction of this thesis. Firstly, it describes the research backgrounds. Then it reviews and analyzes related literatures of domestic and foreign, mainly about website information flow and information flow's distance decay. Then it introduces the goal, significance, methods, and innovation points of the thesis; finally it establishes the contents and framework of this thesis.The second part is about the selection of research subjects and data processing which is the fundamental part of this research. Firstly, it introduces the process of selecting traveling websites and getting data about traveling websites'visitors; then, it is about how to process the research data, mainly using Excel to classify, summarize, and make charts. It makes a strong foundation for the thesis.The third part is about the curve-fitting of traveling websites information flow's distance decay, it is one of the main parts of the thesis. SPSS13.0 software is mainly used in this section. Firstly it examines the relationship between the number of traveling websites'visitors and distance; next it estimates and determines the curve model of traveling websites information flow distance decayThe fourth part is analysis about curve-fitting of traveling websites information flow distance decay; it is the other main part of the thesis. First, it compares and analyzes the curve models of traveling websites information flow distance decay based on the correlation coefficient R and the index of fitting goodness R2 about curve fitting. Second, it analyzes the effects of the type and location of traveling websites on the goodness of traveling websites information flow distance decay curve-fitting. Finally, it analyzes the characteristics of. the traveling websites information flow distance decay.The fifth part is the conclusion, which summarizes the research results and deficiencies of this thesis.
