On the way to travel, the public expect to get a tourism experience with low cost, convenient travel, and high comfort. At the same time, they also have different tourism needs such as history and culture, natural landscape, and food shopping. To address the problem that traditional travel route recommendation algorithms have limited accuracy and only analyze text or pictures alone, we propose a personalized travel route recommendation algorithm that integrates text and photo information from travelogues and obtain the historical tourism footprint of tourists by analyzing travel notes. According to the frequency and cooccurrence of scenic spots in the travel notes and the number of photos taken by each scenic spot, the popularity of scenic spots and the interest preferences of various types of tourists are analyzed. Under the given starting and ending points or passing points, the optimal tourism route generation method is designed. Experiments on the real data set of Ctrip Travel website show that the recommendation accuracy of this algorithm is significantly improved compared with the traditional algorithm which only uses travel notes text or photos. Compared with the algorithm that only considers the popularity of interest points or tourists’ interest preferences, the accuracy of the route recommended by the algorithm is improved. Compared with the algorithm that only considers the cooccurrence of scenic spots or only considers the influence of photos, this algorithm can obtain a better popularity score of scenic spots. This method integrates the two kinds of information including picture and text, fully considering the interest of users with high practicability.
With the development of the times, the leading role of tourism in economic growth has become increasingly prominent. Tourism economic performance is an important standard to measure the development of its economy. However, there is no quantitative research on tourism economic performance within a single region. Therefore, on the basis of relevant research, this paper first constructs the tourism economic performance evaluation system from four aspects such as industrial scale, economic benefits, support power, and input and output. Then, based on the relevant data of tourism indicators in the Pearl River Delta in the past five years, the analytic hierarchy process was introduced to evaluate the economic performance of tourism in the Pearl River Delta. The results show that the tourism industry in the Pearl River Delta has good economic benefits and large industrial scale. However, the social motivation and input-output efficiency supporting the development of tourism are poor. Finally, according to the evaluation results, we put forward the methods and suggestions of tourism efficiency optimization in the Pearl River Delta region, so as to further promote the development of tourism in the Pearl River Delta region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
