Multimodal Wireless Situational Awareness‐Based Tourism Service Scene

Abstract

Community platforms featuring user sharing and self-expression in social media generate big data on tourism resources, which, if fully utilized in a smart tourism system driven by high-tech and new technologies, will bring new life to the field of smart tourism research and will play an important role in the development of Internet+ tourism. However, tourism data in social media has the following characteristics: diversity, redundancy, heterogeneity, and intelligence. To address the characteristics of tourism data in social media, this thesis focuses on the following challenges: it is difficult to efficiently obtain tourism visualization information (text and images) in social media; it is difficult to effectively utilize tourism multimodal heterogeneous information; it is difficult to properly retrieve multimedia entity information of tourism attractions; and it is difficult to reasonably construct tourism personalized recommendation models. In this paper, an image search reordering method based on a hybrid feature graph model is proposed to realize the rapid acquisition of high-quality Internet images from the web using hybrid visual features and graph models, thus providing data security for the analysis of social media-based tourism images. To address the shortcomings of current search engines for image retrieval, visual information is used to bridge the problem of semantic gap between text-based search and images. To address the limitation of single visual features, we use latent semantic analysis to fuse multiple visual features to obtain hybrid features, which not only combine multiple single features but also preserve the potential relationship between these features. To address the shortcomings of the reordering methods based on classification and clustering, a reordering framework based on the graph model is used to reorder the images and finally complete the image search reordering based on the hybrid feature graph model. This method can obtain image information in social media with high efficiency and quality and then prepare for the subsequent work of tourism image analysis mining and personalized recommendation.

Analysis of the path to enhance the quality development of rural tourism with the help of rural revitalization strategy in the context of the Internet

“…This study takes the first and second batch of national rural tourism key villages announced by the Ministry of Culture and Tourism in recent years as the research samples, although some provinces have also selected provincial rural tourism key villages according to the requirements of relevant policies [23][24][25]. However, the national key villages of rural tourism have more distinctive characteristics and more perfect development, so for the sake of data completeness and representativeness.…”

Three-dimensional Visualisation of Cultural Landscape under the Perspective of Culture and Tourism Integration

“…From the industry background, tourism revenue is an important part of local financial income, and the tourism industry is also an indispensable key to the development of the national economy of the whole society. In order to meet the challenges of global informatization and adapt to China's accession to the WTO after the need to make corresponding countermeasures, in the context of the "digital city" environment, the realization of the "digital tourist attractions" is more realistic and urgent [7][8][9].…”
