Introduction
With the development of the tourism industry and the upgrading of the consumer concept of the Chinese people, consumers have begun to seek a deeper tourism experience and the quality of tourism has gradually improved. It no longer considers popular tourism as the first travel option and pays more attention to the personalization and uniqueness of tourism. Many professionals and investors are looking for new tourism models, customized tourism is in line with market growth trends, and its scale is expanding day by day, making it a significant force in the tourism industry. e intelligent age and the rapid popularization of the Internet and the combination of the travel industry and e-commerce have attracted many entrepreneurs to open up the online travel market. New business models, travel service platforms, and apps continue to emerge, such as Qunar, Ctrip, and Fliggy.
e tourism e-commerce platform occupies an important position in the tourism market, driving the rapid development of personalized tourism e-commerce.
Big data is a kind of development based on information and communication technology. It is based on heterogeneous multisource data sets, supported by advanced information storage, analysis, and processing technology, and takes big data thinking as an opportunity. With the exponential growth of data volume and the generation of unstructured data, the data information that needs to be processed has greatly exceeded the ability of traditional database tools and software to collect, store, manage, and analyze, and various new technologies for processing large amounts of data should be applied. e growth of data volume and the development of data technology have made it possible for big data to transform social life. Tourism, finance, medical care, and education have begun to use big data to analyze and solve problems and achieve better results than traditional ones. e e-commerce tourism chain relies on Internet technology to combine the resources accumulated by many carriers, hotels, and other suppliers into a huge database.
rough excavating and analyzing the unique needs of consumers, high-tech data matches response resources and is committed to providing consumers with customized tourism products and services.
Kumoro and Hasanah found that, due to the rapid development of mobile social networks, mobile big data plays an important role in providing mobile social users with various mobile services. However, due to the inherent properties of mobile big data, the current MSN faces the challenge of providing satisfactory big data services to mobile social users. erefore, Su proposed a novel framework for delivering mobile big data through content-centric mobile social networks. First, it studies the characteristics and challenges of mobile big data and then introduces a content-centric network architecture for transmitting mobile big data in MSN, where each data is composed of interest packets and data packets; next, by defining the priority of interest packets and data packets, how to choose a proxy node to forward interest packets and relay nodes to send data packets is given.
is research step is relatively cumbersome and is not conducive to popularization in practice [1]. Liu et al. found that the use of Internet technology has become a new way to provide tourism services, which is also a new direction for the development of China's tourism industry. With the continuous improvement of technology, management, brand, and other factors, the development of China's tourism e-commerce has gradually accelerated. is research is theoretically strong but lacks experimental data support [2]. Wang believes that, with the continuous development of Internet technology, e-tourism e-commerce sites have also achieved rapid growth, with great growth potential. However, China's e-tourism sector is still growing slowly and is facing many problems. erefore, Wang designed an e-commerce travel system based on service-oriented architecture (SOA) and B/S architecture in response to problems in the development of e-commerce tourism and based on the service-oriented design idea. Wang takes tourism companies as its main research object and relies on SQLService technology to conduct research. is method can be used for reference, but it is a bit one-sided [3]. e innovations of this paper are as follows: (1) proposing the use of Bayesian estimation algorithm for tourism big data analysis; (2) proposing the structure design of tourism big data mining; (3) carrying out the tourism e-commerce under the big data era custom travel design. In-depth analysis and impact summary will provide theoretical guidance for this study [4].

Field Trip Method.
In order to truly understand the development status of customized tourism in tourism e-commerce in the EBD, this paper went to relevant tourism e-commerce companies to conduct on-site inspections to learn about customized tourism related information on tourism websites, conduct research on major tourism e-commerce platforms, and collect relevant information onsite. And then after analysis and induction, the obtained data will be used for in-depth analysis of the research topic [5].

Interview Method.
Choose major e-commerce sites, conduct structured interviews with selected travel site managers and employees, collect and organize data, and provide realistic guidance and research base. Structured interviews, also called standard interviews or closed-ended interviews, mean that the researcher asks questions to the respondent in a consistent manner according to a predetermined outline and the respondent chooses from alternative answers, which is in fact a closed verbal questionnaire. e advantages are the high controllability of the research, the high response rate, the strong structure, and the easy quantification [6].

Clustering Algorithm.
e grid-based method quantifies the object space into a limited number of units, forming a grid structure [7,8]. All clustering operations are performed on this grid structure. e main advantage of this method is its fast processing speed, and its processing time is independent of the number of data objects and only related to the number of units in each dimension in the quantization space [9,10].
2 Complexity Each tree must be trained on different random data sets and a group of randomly selected split candidate parameters ϕ � (θ, c) (θ is the feature parameter; c is the threshold) [11].
Divide instance q � (I, x) { } into two left and right subsets q I (ϕ) and q r (ϕ): Calculate the maximum obtained information given by φ:

Support Vector Machine Classification Algorithm.
Assume that the two-dimensional linear discrete function is expressed as e normalized form of the equation of the optimal classification line L is We can express the classifier as follows: e Lagrangian function can be expressed as Finally, the optimization problem of the function is obtained: Get the optimal solution a ′ � (a 1 ′ , a 2 ′ , . . . , a i ′ ) h , and then the modulus of the optimal classifier w ′ has the following formula: e finally obtained tourism data classification function has the following expression:

Bayesian Estimation Algorithm.
Bayesian network is a probabilistic graph model. When learning the Bayesian network structure, it is impossible to evaluate the scores of all networks in the space. You can first use the search algorithm to search for a specific possible space based on the rating function for structure selection. Commonly used search algorithms include hill climbing algorithm, taboo search, and greedy search [12,13]. is paper uses the most commonly used hill climbing algorithm. e basic idea is to start from the initial model, get a series of candidate models through search patterns, and then calculate the results based on the candidate models. Compare the scores of the current model, select the model with the highest score as the initial model for the next search, continue the search or stop the search, and return to the current model [14]. e scoring function uses three functions (k2, BIC, and BDe) for comparison and analysis [15].
In the complete model learning of the data set, maximum likelihood estimation and Bayesian estimation are two commonly used parameter learning methods. e assumptions of these two methods are that the data sample set needs to be independent and identically distributed; that is, for a data set B containing n variables and containing x samples, it can be expressed as en each sample in data set B satisfies the following two conditions. One is that each sample in B is independent of each other after a given parameter α: e other is that each sample b i has the same conditional probability distribution p(b i | α) [16].
(1) Maximum Likelihood Estimation. Maximum likelihood estimation is based on parameter estimation based on the likelihood function of data samples and parameters [17].
ere is a formula: where L(α | B) is the likelihood function of the parameter α after the model is determined, and the logarithm of it can be obtained:

Complexity
(2) Bayesian Estimation. Regarding the question of uncertainty, Bayesian estimation and maximum likelihood estimation have different views. Bayesian estimation believes that parameters are also random variables and need to be assigned specifically. erefore, Bayesian is reasonable in terms of the estimated maximum probability. It is generally believed that the prior distribution of the parameter α is the Dirichlet distribution, and it can be known from the coupling that the posterior distribution of the parameter α is also the Dirichlet distribution [18,19]. For a given data set D, combined with the decomposability of the Bayesian network, the estimated value may appear: Considering that P(α | B) also obeys the Dirichlet distribution, the Bayesian estimate of parameter α can be obtained as e method part of this paper uses the above method to study the impact of tourism e-commerce on customized tourism in the EBD. e specific process is shown in Table 1.

Attractions Data Mining
3.1.1. Data Management System. In the recommendation system, the corresponding data needs to be retrieved from the database at each step, such as scenic spot information database, user registration database, and pattern database. e database management system is responsible for the operation, management, and maintenance of the data in the database [20,21]. e database management system is actually the middle layer between the online recommendation application and the database, and a certain database management system (DBMS) software can usually be used directly [22].

Data Preprocessing.
Data preprocessing is an indispensable stage in the data mining process, because most of the data in the real world are incomplete, noisy, and inconsistent, and the formats of these data are diverse. Data mining algorithms may only mine part of the data in the database. For this, we need to extract useful data. For semistructured data on the web, data preprocessing is even more important. e preprocessing of web usage data mainly includes data cleaning (Data Cleaning) and session identification (Session Identification). Due to the existence of client-side caching and proxy server-side caching, it is necessary to complete the path for the more demanding personalized recommendation service (Path Completion). If the website does not use cookie technology or embedded session identification technology, user identification (User Identification) is required; finally, sequence identification is required for the user's access sequence [23].

Mode Decomposition.
e data analysis basis of the generated pattern is the user purchase database and web server log. e pattern analyzer uses data mining technology to analyze web server log data to obtain relevant information; from the analysis of the user's purchase database, it can find similar patterns of associations between scenic spots when they are selected [24,25]. (2) e Principle of Individualization. e most fundamental purpose of tourists to choose custom tours is to get rid of the travel methods that cut cookies and look for a unique travel form that fits their heart. erefore, when adapting tourism design, the uniqueness of custom design must be reflected to meet the individual needs of tourists.

Customized Tourism Design in
(3) e Principle of Precision. In order to reflect the advantages of customized tourism, it is necessary not only to accurately subdivide customized tourism objects and accurately analyze the needs of tourists but also to reflect the principle of precision in the design from time to time, so that the design can be highly tailored to customer needs and accurately design the plan to realize customized travel.
(4) e Principle of Tourist Participation. e design of customized tours should focus on customer participation throughout the entire process and strengthen customer communication. At the beginning of the design, it is necessary to determine the customized needs and travel details of the tourists through communication; in the design process, it is necessary to communicate with the tourists whether the initial plan meets the expectations of the tourists and find inappropriate places to modify and improve; after the end of the tour, it is also necessary to strengthen the participation of tourists encourages and guide tourists to evaluate this trip. Only when tourists participate in the whole process, can the customized travel plan be perfected and recognized by tourists.

e Realization of Customized Tourism in the EBD
(1) Optimize the Source of Customers. To optimize the source of customers, personalized travel companies must first provide excellent service and sophisticated products to retain tourists, that is, to improve the repurchase rate of old customers through good customer relationship management and on this basis through old customer friends circle to attract customers. Secondly, with the advent of the information age, new technologies such as the Internet, 5G, big data, and artificial intelligence must be fully utilized for the development of online businesses and the good use of the OTA platform. At the same time, as you grow online, do a good job combining online and offline articles. Finally, it actively develops business, develops its own resources, and accumulates customers by expanding service extensions, such as accumulating reputation through other member businesses, developing its own islands, and being a good supplier.

(2) Enhance the Application Ability of New Technical Means.
With the development of science and technology, it is necessary to increase the application of new technical means in terms of obtaining tourist needs and integrating resources, strengthen the extraction and analysis capabilities of big data, and make full use of big data to complete the collection, summary, and analysis of tourist travel choices. For example, use big data to collect information on tourists' flights, railway trips, hotel dining, and other pieces of information to make preliminary positioning of tourists. It is also possible to obtain tourist preferences for tourist destinations and various elements in tourist activities through tourist photos posted in the circle of friends by tourists. e application of new technology is also reflected in the integration of resources by tourism companies. rough big data technology, the integration of resources can be accelerated to provide customers with more and more tailored customized services. e method part of this paper uses the above method to study the impact of tourism e-commerce on customized tourism in the EBD. e specific process is shown in Table 2.

Scoring Function Comparison Result.
For the Bayesian estimation algorithm, the three scoring functions of k2, BIC, and BDe are tested for different standard nodes, the accuracy of all nodes is averaged and variance, and the relevant results are statistically sorted. e specific conditions are shown in Table 3 and Figure 1.
Comparing the overall accuracy rate of the graph and the accuracy rates of cases 1 and 2, the results of the BDe score correlation are better than k2 and k2 is better than BIC. In the case of 0, the accuracy rate is just the opposite, BIC is better than BDe, and BDe is better than k2. In terms of variability, BDe has the lowest variability, followed by BIC, and k2 has the highest variability. In fact, this is related to the sample size of the k2 rating function. When the number of nodes changes, the sample size will change, resulting in a change in prediction accuracy.

Development Status of Tourism E-Commerce Platform in the EBD.
e Internet has become the most important way for tourists to choose customized tourism. Table 4 shows the status of my country's major tourism e-commerce platforms. e downloads of China's major tourism e-commerce platforms that appeared in the search for the keyword "travel" on the mobile phone are shown in Figure 2 (take the Android system search results as an example).

Experimental Results
(1) In order to study the development of customized tourism in the EBD, this paper uses data mining and other related technologies to classify, collect, and organize user data in the tourism e-commerce platform and divide the data into the main goals of customized tourism. is classification standard is based on tourists' specific needs and preferences for customized tourism (such as preferences for tourism elements). e main target groups of customized tourism are shown in Table 5 and Figure 3. It can be seen from the chart that tourists have good satisfaction after experiencing customized travel products designed based on big data mining and analysis. A total of 87.13% of customers indicated that they were in line with their needs, and 79.84% of customers were willing to purchase related products again. In the sample of tourism e-commerce platform, tourists' demand for tourism elements when accepting customized tourism is shown in Table 6 and Figure 4. As can be seen from the chart, when customizing tourism consumption, tourists have the largest demand for food and tourist attractions,   Forecast accuracy (%)

Qunar provides consumers with real-time search of air tickets, hotels, venues, and holiday products, as well as group purchases of travel products and other travel information services, and provides online technology and mobile technology solutions.

Meituan 2010
In April 2018, Meituan travel and UnionPay International reached in-depth cooperation, which will deepen the exploration of technology, big data, and shopping experience to make travel and shopping more convenient. As China's leading e-commerce platform for life services, Meituan travel services cover more than 200 categories, such as catering, takeaway, fresh food retail, taxis, shared bicycles, hotel travel, movies, leisure, and entertainment. 6 Complexity accounting for 32.7% and 36.5%, respectively; accommodation 11.2%; shopping 7.9%; travel mode 7.1%; entertainment 4.6%, the least proportion of demand. e analysis shows that food, scenic spots, and accommodation are the most concerned issues for customers of customized tourism when choosing tourism elements. erefore, these elements need to be the first consideration when making customized design. It can be seen that the related technologies generated in the EBD are conducive to customized tourism to be closer to the needs of tourists, improve customer satisfaction, and promote the development of tourism e-commerce.
(2) e results of the comparison of the improved method applied to different tourism data sets are shown in Table 7 and Figure 5.
According to the data in the chart, it can be seen that when the support threshold is the same, the frequent set mining effects of different data sets are basically similar. (3) After using big data technology to design customized tourism products for tourists, conduct online surveys, return visits to customers, investigate and analyze customer satisfaction and feedback for the products, and organize relevant data, as shown in Table 8 and Figure 6. It can be seen from Figure 2 that the current downloads of major tourism e-commerce platforms are all over 100 million. e market for tourism e-commerce platforms is vast and the demand for tourists is large, which is conducive to the development of customized tourism products.  Fliggy provides online booking services for more than 200,000 domestic and overseas hotels, homestays, inns, and serviced apartments, provides multiple domestic and outbound tourist routes, and provides one-stop services such as phone cards, overseas Wi-Fi, car rental, and visas; full coverage tickets for many paid attractions at home and abroad can be booked online with one-click reservations; online bookings for domestic and most mainstream international routes and all domestic train tickets are provided.

Tongcheng 2004
Tongcheng tourism is a national high-tech enterprise and the first batch of e-commerce demonstration enterprises by the Ministry of Commerce. Tongcheng tourism has been selected as one of the "top 20 China tourism groups" for three consecutive years. It ranked 9th in 2014 and 8th in 2015. It is one of the three major enterprise groups in China's online travel industry. In the new ten years, the company takes "the first place in leisure tourism" as its strategic goal, uses scenic spot tickets as the entrance, and actively deploys peripheral tourism, long-term tourism, cruise tourism, and other business sectors.

Conclusions
With the rapid development of social networks, huge amounts of travel data have been created on the Internet, resulting in the emergence of information overload. It takes a lot of energy for users to get effective information from it, which makes users increasingly in demand for effective travel information search. e study of personalized search and customized service system for tourism e-commerce big data has important theoretical and application significance. e research work in this paper is mainly focused on the customized tourism of tourism e-commerce in the EBD. By using the various characteristics of tourism big data for data mining and classification, it provides users with personalized travel search services. At the same time, big data technology can provide basic technical support for customized tourism development, which shows that it can also provide customized services for users.
