## Abstract

Due to the narrow range of route search and the single choice of the optimal route during the peak period of tourists' tourism, resulting in a long walking time and relatively high route cost, an intelligent tourism information service model considering tourists' experience is proposed in the environment of Internet of things. Firstly, the overall architecture of the Internet of things environment is designed to obtain the characteristic data of the carrying capacity of scenic spots, including tourism resources, psychology, ecology, and economic carrying capacity, based on which the tourist perception experience model is constructed; different service functions such as in-depth mining of Web content, personalized information push, and data information conversion under the environment of Internet of things and the construction of intelligent tourism information service model are realized. The experimental results show that the passenger flow prediction error of the designed model is small and has a good prediction effect of tourist attraction selection demand.

## 1. Introduction

Driven by the rapid development of information technology and Internet technology, tourism has ushered in a golden period of rapid growth. With the gradual development of the national economy and the increase in leisure time and disposable income, tourism has become an important way of entertainment for residents [1]. Because ecotourism has the characteristics of objectivity, dynamics, and management, it is difficult to measure its environmental carrying capacity. There are still great disputes on the selection of indicators and influencing factors [2]. In the open Internet of things environment, the total amount of data information shows a geometric growth, which causes great resistance to the rapid retrieval service of data information [3]. In the Internet of things environment, it is impossible to quickly confirm the current location and return to the specified node. Secondly, due to the limited receiving and holding capacity of information users, it is difficult to correctly understand and apply information [4,5]. Although the emergence of various search engines has satisfied the basic needs of information users to a certain extent, the quality of information retrieved is poor due to the huge amount of Internet information and the existence of information overload [6, 7]. Considering the tourist experience, the intelligent tourism information service model is established, which not only has the function of fast retrieval and collection but also integrates the Internet of things retrieval functions such as personalized database, favorites, and hyperlinks, which significantly improves the information retrieval efficiency.Reference [8] presents an assessment of the comparative advantage shown by Ukraine's export of tourism services to the EU. For those countries where tourism is an important source of national income and a job-creating activity, the question of tourism and the revitalization of the tourism sector become urgent following the devastating consequences of the pandemic. Tourism stimulates the development of small- and medium-sized enterprises, has great potential for a creative economy, enables rapid recovery of costs, has a significant environmental impact, and enables a high degree of social inclusion, including the use of women and youth labour. Reference [9] proposed the impact of applied quality standards on improving environmental tourism services in nature reserves in southern Jordan. The study population included tourists from all nature reserves in southern Jordan. Descriptive analysis was used to conduct a field survey of 600 visitors to a nature reserve in southern Jordan, selected by a simple random method, through questionnaires. Using statistical analysis of social science statistical procedure according to the results, in the south of Jordan nature reserves, tourist service quality standards to improve the environment have a significant statistical effect, and the study suggested southern Jordan nature reserve management department to make a plan, through continuous application of quality standards, to ensure to improve its ecological tourism services.Although the above research has made some progress, there is less consideration of tourists' experience. Therefore, an intelligent tourism information service model considering tourists' experience in the Internet of things environment is proposed to adapt. The overall architecture of the Internet of things environment was designed to obtain the characteristic data of tourist attractions' carrying capacity, and based on this, the tourist perception experience model was constructed. Different service functions such as in-depth mining of Web content, personalized information push, and data information conversion can be realized in the Internet of things environment, to adapt and meet the personalized information retrieval and use needs of tourists in the Internet of things environment.

### 2.2. Obtain the Characteristic Data of Carrying Capacity of Scenic Spots

From the perspective of tourists' experience and keeping the tourism demand and tourism supply of the scenic spot in a relatively ideal state, the transportation carrying tools of tourists and the facilities or space occupied by them in a specific time are determined through the combination of quantitative and qualitative methods, to obtain the characteristic data of the carrying capacity of the scenic spot, including the carrying capacity data of tourism resources, tourism psychological carrying capacity data, tourism ecological carrying capacity data, and tourism economic carrying capacity data [12,13]. The specific contents of data acquisition are shown in Table 1.Table 1

### 2.3. Tourist Perception Experience Model

Tourism activities involve many factors, not only taking tourists as the main participation but also taking the image of the scenic spot as the main behavior. Scenic spots attract tourists with specific resources and carry out relevant activities. Whether tourism resources have a certain tourism attraction depends not only on the tourism resources of the scenic spot but also on the comprehensive object environment of the scenic spot [14, 15]. The tourism environment is an important carrier of tourism activities. The tourism environment is one of the important factors for tourists to consider whether the scenic spot is worth traveling. For example, the quality of the natural environment often affects the experience of tourists in this process. If the scenic spot has good tourism resources, but it rains or earthquakes frequently all year round, then tourists will not come to visit. It can be seen that tourism environmental factors are very important.Tourists bring economic benefits, promote employment, promote the protection of ecological environment and traditional culture, and inevitably bring many negative effects caused by their own lifestyle and behavioral habits to the scenic spot. Therefore, it is of great practical significance to study tourism information services from the perspective of tourists [16].ACSI represents the core concept and architecture of tourism motivation, purchase policy, tourism, and tourism process when tourists play. As a dynamic and continuous experience process, the end of tourism can establish a tourist perception experience model through the dynamic process of tourists' comprehensive experience [17, 18]. The specific content is shown in Figure 2.Figure 2
Tourist perception experience model.As can be seen from Figure2, the tourist perception experience model is built on the basis of tourist resettlement experience. Tourist perception experience is a kind of social perception that tourists perceive the impact of tourism, including the perception of economy, social culture, environment, self, interpersonal relationship, and social role. Tourism experience is generated in every link of tourism product consumption, from landscape appreciation to the acquisition of various services, and the quality of service in each link will affect the quality of tourist experience [19,20]. The accuracy, safety, comfort, and reliability of information transmission determine the service quality of each element. Therefore, tourists can obtain more accurate comprehensive perception experience through the perception of tourism landscape quality, service quality, and environmental quality.Table 2

## 3. Realize the Design of Intelligent Tourism Information Service Model considering Tourist Experience

### 3.1. Design of Information Service Function Module

Consider intelligent tourism information service model of tourist experience, which is divided into four modules, respectively, as tourism information module, the network data retrieval module, push module, and database module, to realize the Internet environment, the depth of the Web content mining, data conversion and other personalized information push service function, the structure of the model, and the main function module design, as shown in Figure3.(1)
Visitor Module. The intelligent tourism information service model based on multimode takes tourists as the service center. The functions of the tourist module include basic information management and customized management of tourists' information needs. All personal information and account information of tourists are stored in the module. After authorization, you can enter the account and password to log in to the system. After entering the system, tourists can add, edit, and modify tourist information by themselves after being authorized by the system administrator; through this module, tourists can put forward specific tourism information retrieval needs, customize the database list, and select the retrieval and classification query methods of tourism information. The module has the function of automatic storage and retrieval, and the historical retrieval content can be queried through keywords.(2)
Network Data Retrieval Module. This module is the core module of the tourism information service model, through which tourists can retrieve and customize the content of interested weblogs [21]. To adapt to the compound multi-data transmission mode, a data retrieval network is designed. The network has good compatibility and supports different modes such as static data transmission and dynamic data transmission. The bus matrix can process 64 bit data input and output in parallel, with four I/O interfaces. The network data retrieval module can deeply mine and analyze the contents of the network log and actively switch the mode of tourism information retrieval according to the use habits and preferences of tourists, to obtain the retrieval habits of tourists and store keywords and characteristic words in the database, to facilitate the subsequent data call of tourists.(3)
Tourism Information Push Module. The tourism information push module includes the specific functions of pushing tourism information management, tourism information generation, and tourists' use feedback. The total amount of tourism information in the network is huge, and the total amount of data information collected according to tourists' habits and preferences is huge. Push management is to preprocess and classify this redundant and wrong tourism information first, retain useful tourism information, and eliminate interference information [22,23]; through the classified retrieval of customized tourism information for tourists, the most economical tourism information transmission mode is selected in the Internet of things environment, the tourism information categories required by tourists are generated, and directional and regular push is realized [24]. The tourism information push module has a two-way information interaction function; that is, on the one hand, it transmits basic tourism information to tourists, and on the other hand, it also receives tourists' feedback, to optimize each module of the system and continuously improve the database [25].(4)
Database Module. According to the above three modules, the list category of the database is divided into tourist basic tourism information data, tourist search tourism information table, and personalized data table, as shown in Tables 2–4, respectively.Figure 3
Structure diagram of main functional modules of intelligent tourism information service model.Other forms in the database are extended and expanded on the basis of the basic form and connected with the basic form through the primary key field, which is convenient for tourists' retrieval and query.


### 3.2. Realize Intelligent Tourism Information Service Model

The Internet of things is taken as the goal of tourists' experience perception, an intelligent tourism information service model is established through intelligent perception, a large number of tourism-related real-time information are mined through the Internet of things, such as scenic spot tickets, accommodation places, weather, and meteorology, this information is gathered and analyzed, and the tourism information available for service is summarized [26,27].To establish an intelligent tourism information service model, we need to take the big data of the Internet of things as the goal and use multi-agent technology to divide the establishment of the model into multiple modules, namely data acquisition, data perception, data decomposition, data storage, data integration, central control, and data display modules. Among them, data acquisition is responsible for the input of the model, collecting the tourism big data of the Internet of things through the compiled crawler program, making preliminary selection and filtering, and submitting the data to the data decomposition module after completing the preliminary processing; the data decomposition module decomposes the collected data into multiple parts through extraction, filtering, decomposition, and other operations and submits them to the perception module [28]; after sensing the tourism information, the perception module in the platform selects the tourism data with service value in a unified format through weighted calculation and normalization processing and then integrates this data information with service value into independent data through the data integration module, which is stored in the data storage module, managed storage, and provided to the data display module, and the data are displayed in front of tourists.The central control module is responsible for connecting each module in the perception model, controlling the information exchange of each module, and the processed request link queue established by the manager in the process of obtaining the tourism data of the Internet of things, so that the whole platform can effectively process the tourism big data and communicate information [29].In the above, the data collection is mainly realized through the Web page analysis algorithm, which is not simply judged according to whether all the text of the Web page is related to the given subject. This judgment method lacks certain reliability. In the process of establishing the intelligent tourism information service model [30], the data collection is mainly based on the theme relevance of the parent Web page of the Internet of things. The correlation between the current Web page and the theme and the location of the Web page link is comprehensively determined. The final result may be a continuous value between 0 and 1. The closer the value is, the higher the correlation between the collected data and tourism service information, which proves that the collected data are the target data of the platform [31,32].Assuming that the 0/1 mode is used to represent whether tourists have been to the scenic spot, the check-in times of tourists correspond to the degree of interest of tourists in the scenic spot. Therefore, the similarity between tourist interest points is solved using the check-in times of tourists in the scenic spot, and the expression is as follows:(5)Xqd=∑yi,j×yk,j∑yi,j.In formula (5), yi,j represents the check-in frequency of a tourist yi,j in scenic spot j and yk,j represents the check-in frequency of another tourist in scenic spot j.The firstN′ tourists with the greatest similarity are selected according to the similarity between tourists. These tourists are used to form a set U′, and the possibility that tourists will go to the scenic spot without checking in is solved according to the collaborative filtering model based on tourists. Then, the formula is as follows:(6)Yqd=∑Xqd×yk,j∑Xqd.Assuming that a tourist has been tom cities, the expression of the number of interest points that can be mined is obtained according to the sign-in times and stay time of his activity track:(7)Zqd=∑lcm×Xqd×Yqd.In formula (7), lc represents the vector set represented by the points of interest. To ensure that the mining of interest points is comprehensive enough, it is necessary to use the characteristics of tourist similarity, social relations, and geographical location information to realize the mining [33,34]. Because the probability values of interest points are different, the standardized weighting method should be used for processing during integration, and the processing results should be substituted into the model of mining interest points. The construction of intelligent tourism information service model can be realized [35,36], and its expression is as follows:(8)Sab=Pab×Zqd×λ.In formula (8), Pab represents the collection of users check-in interest points, and λ represents the training parameters. Intelligent tourism is a highly complex and dynamic field. Intelligent tourism information service providers often need to rely on models to predict the marketing objectives of the tourism market and explore the potential market. Users also need tourism information to assist decision-making. These need to be realized through the organization and integration of intelligent tourism information service models. There is an urgent need for an Internet of things processing technology to organize them in depth. In the Internet of things environment, various network information technologies are used as a structured data application specification, to realize the construction of intelligent tourism information service model considering tourist experience in the Internet of things environment.

Users also need tourism information to assist decision-making. These need to be realized through the organization and integration of intelligent tourism information service models. There is an urgent need for an Internet of things processing technology to organize them in depth. In the Internet of things environment, various network information technologies are used as a structured data application specification, to realize the construction of intelligent tourism information service model considering tourist experience in the Internet of things environment.
