## Body

## 1. Introduction

The development and application of information technology have brought a great impact on traditional e-commerce, making it change. The high division of labor and cooperation based on information technology is becoming more and more popular and deepening. E-commerce has become the basic driving force for business reform, and e-commerce will become one of the main directions of Internet development in recent years. The mobile platform is different from the mobile development platform and the mobile application platform. It is a unified platform covering the whole life cycle of mobile application development, management, security, and integration. Business transactions are mainly carried out on the Internet, and the massive data it produces are isolated. However, in these isolated massive data, traditional methods cannot mine valuable knowledge. Therefore, it is necessary to obtain valuable knowledge by mining association rules of data.The network may give numerous types and amounts of commodities in the network virtual environment, but it is difficult for users to identify attractive commodities within a particular range. People today have a greater desire to obtain relevant information in a short period of time. As a result, individuals study and evaluate the huge data created by e-commerce at a higher level in order to get information. E-commerce data mining has been extensively employed to gather complete features of these data and estimate the growth trend. On the basis of connected data produced by data mining algorithms, people may mine valuable data and information.(1) Introducing theoretical knowledge of e-commerce and data mining, and using data mining to examine the value of large data mining techniques in e-commerce consumption patterns based on mobile platforms are the contributions of this study. (2) Examining the benefits of e-commerce is as seen by customers. Experiments have shown that e-commerce not only enables individuals to purchase what they need online, but it also saves them a lot of money.


## 2. Related Work

With the economic development in recent years, the development of e-commerce is also getting faster and faster. HuL found that Internet-based e-commerce has rapidly developed with its unique advantages. However, the openness of the Internet makes payment security and privacy protection an obstacle to the development of e-commerce. Based on this, he proposed a double encryption algorithm, which can reduce the complexity of data encryption and decryption, shorten the time of data encryption, and protect people's privacy and security. However, the scholar did not verify the reliability of the algorithm through specific experiments [1]. Nalepa GJ proposes a system for sharing a physical display screen among multiple applications on a mobile platform, including an Internet-connected client device and software that performs tasks on the client device. The software provided the first function of assigning dominance to one of several applications, which greatly facilitated the development of mobile platforms. But the scholar did not explain the construction principle of the system and its advantages [2]. The purpose of the Kwak S Y study is to determine the factors that influence the repurchase willingness of overseas direct purchases, which is one of the business models of college students' cross-border B2C e-commerce. He found that repurchase intention is influenced by consumer satisfaction, and factors that influence consumer satisfaction include price competitiveness, product attributes, reputation, and delivery services. He built a system that could handle various language support and refunds for product returns to eliminate consumer anxiety. Although the scholar saw the problems in e-commerce and established a system to increase people's repurchase rate, he did not verify whether the system was feasible [3]. Zhang B found that with the rise of emerging technologies and consumption patterns in the context of “big data,” e-commerce has become mainstream. He employs an ordinal logit regression model to reveal the key drivers of consumer choice for e-commerce. The results show that the factors that people choose to consume in the e-commerce mode are as follows: the convenience of buying things, the lower cost, the ability to buy the most suitable products through comparison, and so on. However, the scholar did not mention how to use the logit regression model to discover these factors [4]. Chen J found that C2M is a new type of Internet e-commerce model. He analyzed the online shopping mall as the representative platform of C2M. With the help of the PEST analysis method, he investigated the macrodevelopment environment of e-commerce, and the results show that e-commerce is basically conducive to the development of the social environment. However, the scholar did not describe the content and data of the entire experiment, making his view unreliable [5]. Kavakiotis I finds that remarkable advances in biotechnology and health sciences have led to the generation of massive amounts of data, such as large amounts of genetic data and clinical information generated from large electronic health records. Data mining plays the biggest role in prediction and diagnosis in medical care, and it can help improve the work efficiency of relevant personnel. But the scholar did not describe why the application of data mining in biological sciences is more important than ever [6]. The mining of household monthly electricity consumption patterns, according to Zhou K, is used to uncover various energy use patterns of homes over the course of a month using data from household daily power consumption. He improved a fuzzy clustering approach for mining residential monthly power use patterns in this study. He began by discussing the history of clustering, followed by a process model for mining residential power use patterns and an enhanced fuzzy clustering model. Although the researcher provided particular answers to specific difficulties, he did not discuss the model's benefits, making it harder to persuade [7]. Mero J discovered that offering outstanding customer service and reciprocal communication via the company's website is a key step to attract and keep clients in e-commerce retailing, where rivals may compare product pricing with only one click. He discovered that “live chat” has become a more popular way of engaging with customers, since it allows them to conduct online real-time chats with customer care agents, which may more quickly help them complete the transactions. Although the researcher discovered that real-time communication may speed up transaction completion, he could not provide any examples to back up his claim [8].


## 3. E-Commerce Consumption Patterns and Basic Concepts of Data Mining

The rapid development of information makes the Internet produce distributed and dynamic large-scale massive data, and the Internet has become an open information service platform and provides people with a lot of information resources and convenient services [9]. The emergence of e-commerce has greatly changed people's lives, as shown in Figure 1:Figure 1
The application of e-commerce in life.As shown in Figure1, different from the traditional business model, the transaction behavior in the e-commerce platform takes the virtual shopping environment as the carrier, the computer and the Internet as the communication method, and the online banking and express service to complete the new business model of capital flow and logistics. This means that it must use information technology, data processing, etc., as shown in the main technical support [10].This study conducts a survey on the average weekly online time of people from 2012 to 2020, as shown in Figure2.Figure 2
Average weekly time spent online by people, 2012–2020.As shown in Figure2, from 2012 to 2020, people spend more and more online time per week on average, which shows that people more and more frequently use the Internet. In the explosive information age, people are in the Internet environment of large-scale data and diversified data sources [11].Simultaneously, as science and technology have progressed in recent years, data mining and other technologies have become more capable of processing massive amounts of data. Data mining [12] solves the issue of processing power and computational complexity in this manner. Finally, the advancement of different data mining techniques gives a theoretical basis for large-scale user data analysis, as seen in Figure 3.Figure 3
Data mining model in e-commerce.As shown in Figure3, this model can not only correlate the data in the field of e-commerce but also mine new knowledge through the associated data, which has important research value and practical significance for promoting the development of e-commerce [13]. This dissertation does some research on the linked data of e-commerce and the construction of the e-commerce knowledge mining model based on linked data.Judging from the development trend of e-commerce from 2015 to 2018, it is expected that the shopping mode will strongly support the overall development of e-commerce. The percentage of sales of each e-commerce website is shown in Table1.Table 1
Percentage of sales by e-commerce site.

In terms of commodities, apart from digital commodities, the first online shopping clients develop with time, influencing the purchase behavior of their peers and newcomers. Customers who shop online are progressively shifting their buy categories to domestic items and other everyday essentials, which will have an impact on the market's overall growth.The Internet shopping business is also seeing fast expansion in terms of penetration into cities. These users will represent a new force for the expansion of online purchasing consumers in the future as network penetration improves and grows [14]. Figure 4 depicts the structure of e-commerce.Figure 4
Structure of e-commerce.As shown in Figure4, the main consumption patterns of e-commerce are as follows.


### 3.1. E-Commerce between Enterprises and Consumers (Business to Consumer or B2C)

This model is mainly implemented between enterprises and consumers by enterprises that implement online sales activities such as Amazon bookstores, and the typical use of e-commerce is online shopping [15]. This type of e-commerce is rapidly growing in recent years with the opening of new transaction platforms for businesses and consumers and the increase in global Internet users.


### 3.2. Business to Business (B2B) between Enterprises

E-commerce has existed for many years, and B2B refers to business activities carried out by enterprises through private networks and value-added communication networks [16]. This is the mainstream of e-commerce, and it is also a new method for enterprises to innovate, improve their competitive conditions, and strengthen their competitiveness in the face of fierce market competition.


### 3.3. E-Commerce between Consumers (Consumer to Consumer or C2C)

By providing buyers and sellers with an online trading platform, the C2C business platform enables sellers to take the lead, provides online auctions of commodities, and enables buyers to choose bidders' commodities [17].


### 3.4. E-Commerce between Offline Business and the Internet (Online to Offline or O2O)

O2O refers to attracting clients by leveraging offline services online. The most significant purpose of this model is to validate the impact of promotions and trace each transaction [18]. Consumers may pick services and pay transactions online. Figure 5 depicts the e-commerce transaction model.Figure 5

## 4. Data Mining Method Based on Mobile Platform

Data mining is the technique of using algorithms to find information buried in a vast volume of data. Statistics, online analytical processing, intelligence retrieval, machine learning, expert systems, and pattern recognition are some of the approaches used in data mining, which are mainly connected to computer science. Cluster analysis, association rule approaches, and other data mining algorithms are often employed. The following are some of the most common knowledge mining algorithms.


### 4.1. Customer Consumption Cluster Analysis Method Data Mining-Based Data

The analytical method of grouping a collection of physical or abstract things into classes of related objects is known as cluster analysis. It is a crucial aspect of human conduct. Cluster analysis aims to gather data in order to categorize it based on similarity. People want to identify hidden laws in relevant data using data mining technologies in the massive database system in order to drive the industry's growth [19]. However, owing to a large amount of data in the database, raw data must be preprocessed to prevent wasting resources.The normalization of raw data is as follows:(1)Qij=Aij−aiSj.Among them,Aij is the jth attribute value of the ith index, Sj is the standard deviation of the jth index, and Qij is the standardized index. The specific equation for calculating the correlation coefficient matrix is as follows:(2)R=QijQiiQjjp×p.Among them,Qij is the covariance of ai and ai.In this study, the clustering algorithm is applied, which is regarded as the preprocessing step of the association rule prediction in the following data mining. The specific equation is as follows:(3)θi=λj∑j=1Pλj.Given a datasetλj, λj class must satisfy that each class must contain at least one data record, and each data can only belong to one class.Traditional clustering techniques have certain drawbacks when it comes to client segmentation. Because the K number is chosen at random, and finding a clear K value is typically difficult, it is hard to estimate how many classes the given dataset should be split into to be the most suited [20].The acquired initial cluster centers in this study have high stability, and the objective function's convergence time is quick [21], thanks to the use of a greedy approach and a distance balancing function across classes to solve the first cluster centers. The greedy algorithm refers to the greedy algorithm in general, and the greedy algorithm indicates that it always chooses the best decision in the present perspective while solving a problem. In other words, the method provides a local optimum solution in a sense without considering overall optimality.In this study, the validity function is selected to calculate the number of clusters K, which is defined as follows:(4)DBU=1C∑i=1cmaxΔAi+ΔAjδAi+Aj.Among them,ΔAi and ΔAj represent the intraclass distance, δAi+Aj is the interclass distance, and c is the number of clusters in the data space U [22]. When the value of DBU is the smallest, the corresponding K is the optimal number of clusters. In equation (4), this study uses the centroid distance instead of the interclass distance, and the coordinate value of each point needs to be used to find the interclass distance. Usually, the average value of each point in the class is selected as the representative. The specific equation is as shown in the following:(5)δAi+Aj=dvx,vy.Among them,d is the Euclidean distance represented by equation (5), and the average values of the coordinates are vx and vy, as shown in equations (6) and (7):(6)vx=1Ai∑a∈AiA,(7)vb=1Aj∑a∈AjA.Recalculating the average value∑a∈AjA of these K clusters, they are assigned to K clusters according to the principle of nearest distribution, and the iteration is stopped until the average value of the initial cluster center does not change.The objective function of the traditional K-means algorithm just overemphasizes that the intraclass distance is as small as possible, while ignoring the problem that the interclass distance is as large as possible. Therefore, when using the improved K-means algorithm to find the initial cluster center, the interclass distance is also included in the study. The objective function is redefined such as:(8)Hc,k=Xc×Xc+Yc×Yc.Among them,Xc represents the sum of the intraclass distances of K classes, and the specific calculation method is as follows:(9)Xc=∑i=1kXCi=∑i=1k∑ai∈cida,Ci.In equation (9), Ci represents the class, and ci and ci represent the coordinate mean, respectively. The value of the objective function is minimized, the intraclass distance is the smallest, and the interclass distance is the largest.Equation (9) is used to find the distance between sample a and the dataset and find the maximum distance dmaxa,S and minimum distance dmaxa,S, which are shown by equations (10) and (11), respectively:(10)dmaxa,S=maxdai,aj,aj∈S(11)dmina,S=mindbi,bj,bj∈S.When constructing the distance balance functionL, it is calculated based on the minimum distance dmina,S. The objective function is the form of the goal pursued by the design variables, so the objective function is the function of the design variables. According to the defined objective function, the distance balance function equation is constructed, and the equation is used as a standard to assign the data to the dataset dmaxa,s. The definition is shown as follows:(12)L=dmaxa,s+dmina,s×dmaxa,s−dmina,sK.In order to visually check the clustering execution time before and after the improvement, the comparison chart corresponding to the experimental results of the K-means algorithm before and after the improvement is shown in Figure6.Figure 6
Clustering effect of K-means algorithm before and after improvement. (a)The clustering effect of the K-means algorithm before the improvement. (b)The clustering effect of the improved K-means algorithm.
(a)(b)As shown in Figure6, the clustering effect of the K-means algorithm before the improvement increases with time, and the clustering effect drops from 60% to 10%, while the clustering effect of the improved K-means algorithm drops from 40% to 5% and then increased to 70%. The customer's consumption behavior is analyzed by the improved K-means algorithm, the optimal number of clusters K is obtained, and the stability of the obtained initial cluster centers is good. Using this method will improve the accuracy of clustering and reduce clustering time.


### 4.2. Association Rule Algorithm Based on E-Commerce Model

With the development of information technology and Internet technology, e-commerce has been popularized as a new and efficient business model. Users can complete complex commodity buying and selling actions just by clicking the mouse in front of the computer. Although fast, it also creates the problem of information overload. The association rules in e-commerce are shown in equation (7) as follows:Data mining technologies, as demonstrated in Figure7, may help to alleviate the issue of information overload. The internal link between the items offered and the products and consumers may be discovered by mining the association rules, which has a significant guiding relevance for the storage strategy.Figure 7
Application of association rules in e-commerce.Association guidelines are a significant step forward in data mining. Many researchers have investigated this rule in depth since it was introduced. The essential notions of association rules are initially introduced in this study.LettingA⊆I, M transaction set D contains the number of transactions of A, N is the number of all transactions in transaction set D, and the probability of M appearing in N is the support degree, as shown in the following:(13)SupportA=MN.Confidence: HypothesesA⇒B, A⇒I, A⇒I, and A∪B. The confidence is as shown in the following:(14)Confidencer=SupportA∪BSupportA.The support and trust of the rule are shown by equations (13) and (14). If the support degree is greater than the set minimum threshold support degree, and the trust degree is greater than the specified minimum threshold trust degree, the rule is a strong rule.


### 4.3. E-Commerce Model Based on Outlier Data Mining

Outlier data may hide some real and unexpected knowledge, which need to be taken seriously by researchers. A data stream consists of a series of ordered, infinite, and dynamic data arriving in an orderly manner. Outlier data mining on data stream is an emerging topic of data mining, which has a wide range of applications in daily work. The discrete model in two-dimensional space is shown in Figure8.Figure 8
Discrete model in 2D space.As shown in Figure8, the data objects and their connections to the three nearest data are marked with dotted lines in the figure and the arc size of the corresponding average nearest neighbor distance. Obviously, among the six data objects, the outlier objects have larger average neighbor distances, while the average neighbor distances of other nonoutlier objects are relatively small. In order to be able to numerically compare them, some further definitions are needed.The maximum distance between the useru and other users v in the user set is called the maximum reachable distance MRDv, as shown in the following:(15)MRDv=maxdistu,v|u∈U.In order to balance the scales of different users' ratings of purchased products, the ratings of N users in datasetDatasetn,m are standardized. The average rating of the user's rated purchased product is recorded as 1, as shown in the following:(16)Meanv=∑i∈IuruiIu.Among them,Iu presents the number of elements in set IuThe standard deviation of the ratings of the user's rated purchased products is recorded asStdv, as shown in (17)Stdv=∑i∈mrui−Meanv2Iv−1.Then, the user v's rating on the purchased producti is standardized as follows:(18)RuiV=Rui−Meanvstdv.


### 4.4. Artificial Neural Network Model Based on Data Mining

An artificial neural network is a research hotspot in the field of artificial intelligence since the 1980s. It abstracts the human brain neuron network from the perspective of information processing, establishes a simple model, and forms different networks according to different connection methods. In engineering and academia, it is often simply referred to as a neural network or neural-like network. The neural network is an operation model, which consists of a large number of interconnected nodes. The strength of connections between neurons of an artificial neural network is varied and can be adjusted. Therefore, based on this characteristic, the human brain has the function of processing and saving information. Similarly, using multiple basic electronic components to simulate the neurons of the human brain can reflect the basic characteristics of the human brain and abstract the learning ability of the human brain.The input of the neuron can be expressed asa1,a2,…,an, and the output of the neuron can be expressed as follows:(19)hw,ba=fwt,a.The functionf is called the activation function, and the sigmoid function or the tanh function is usually selected. Assuming that there are m training samples in the output layer of the neural network, the cost function for a single training sample is as follows:(20)JW,a,b=12hw,ba−b2.There is a huge amount of data in e-commerce that needs to be addressed so that neural networks can really do their job. The more data the neural network takes, the better the performance. Conversely, if traditional machine learning algorithms reach a certain level, performance will not improve even with more data.

It abstracts the human brain neuron network from the perspective of information processing, establishes a simple model, and forms different networks according to different connection methods. In engineering and academia, it is often simply referred to as a neural network or neural-like network. The neural network is an operation model, which consists of a large number of interconnected nodes. The strength of connections between neurons of an artificial neural network is varied and can be adjusted. Therefore, based on this characteristic, the human brain has the function of processing and saving information. Similarly, using multiple basic electronic components to simulate the neurons of the human brain can reflect the basic characteristics of the human brain and abstract the learning ability of the human brain.The input of the neuron can be expressed asa1,a2,…,an, and the output of the neuron can be expressed as follows:(19)hw,ba=fwt,a.The functionf is called the activation function, and the sigmoid function or the tanh function is usually selected. Assuming that there are m training samples in the output layer of the neural network, the cost function for a single training sample is as follows:(20)JW,a,b=12hw,ba−b2.There is a huge amount of data in e-commerce that needs to be addressed so that neural networks can really do their job. The more data the neural network takes, the better the performance. Conversely, if traditional machine learning algorithms reach a certain level, performance will not improve even with more data.


## 5. Experiment and Analysis of E-Commerce Consumption Patterns

### 5.1. Experiment and Analysis of the Development Trend of E-Commerce

Promotion is a kind of marketing approach that many businesses use. E-commerce advertising activities come in a variety of shapes and sizes. Consumers' buying behavior is synchronized with the enjoyment of preferred advantages via methods such as discounts, complete discounts, and gifts. Many other types of promotions do not deliver rewards to customers right after they make a purchase; instead, they must wait a set amount of time thereafter or satisfy particular criteria before they may enjoy them. These kinds of promotions are known as delayed profit promotions.This study conducted a survey on 50 consumers and made statistics on their own situation, as shown in Table2:Table 2
Fifty consumers' own situation.

Among the 50 consumers, 10 are 15–25 years old, accounting for 20%; 20 are 25–35 years old, accounting for 40%; 15 are 35–45 years old; the proportion is 30%; and there are 5 people aged 45–55 years, accounting for 10%. It can be seen that the desire of women to consume is higher than that of men, and the level of income will also affect shopping behavior. The higher the consumption, the more the shopping times.This study further investigates the consumption behaviors and selects promotional methods of these 50 consumers, as shown in Tables3 and 4:Table 3

Statistical itemsNumber of samplesProportion (%)Discount promotion2244Flash sale1836Quantity discount1326Gift vouchers1020As shown in Table3, among the 50 consumers, only 2 consumers have less than 5 online purchases per month, accounting for 4%; 25 consumers have 5–10 online purchases, accounting for 50%; and 10 times, 23 people, accounting for 46%. So it can be known that with the development of e-commerce, more and more people tend to shop online.As shown in Table4, in terms of e-commerce consumption behavior, promotion methods include a discount promotion, limited-time snap-up, large-volume discounts, gift vouchers, and so on. There are 22 people who choose discount promotion, accounting for 44%, and 18 people who choose time-limited grabbing, accounting for 36%. From the data in the table, it can be seen that the number of consumers who choose discount promotion is the largest, indicating that discount promotion is the most popular consumption mode.This study surveys 10 consumers about their views on the advantages of e-commerce, as shown in Figure9.Figure 9
Ten consumer perspectives on the advantages of e-commerce.As shown in Figure9, e-commerce has three characteristics: convenience, low cost, and competitiveness. It is precisely because of these advantages that the current e-commerce market is very active, and the future e-commerce still has broad prospects for development.


#### 5.1.1. Convenience

First and foremost, e-commerce transcends time and geography. Users of online shopping may peruse items at any time of day or night as long as they switch on their phones and click to visit the store without leaving their homes. Second, without using too much time and energy, all components of the e-commerce operating process are smoothly integrated, with one-click ordering and one-stop service. Furthermore, e-commerce allows for a number of payment methods, numerous shipping services, visibility of the transaction process, and the provision of a variety of high-quality services to customers.


#### 5.1.2. Cheap Price

E-commerce is a method of trade that utilizes a computer network infrastructure. This method not only avoids a lot of intermediary connections, compressing the profit area of layers of intermediaries, but also exempts rent, décor, water and energy, and other expenditures. It may help customers save a lot of money on purchases, and it can help e-commerce businesses enhance their pricing competitiveness.


#### 5.1.3. Competitiveness

Using e-commerce means to sell, each enterprise will publish its own products and related information on the Internet, and any other competitor can easily understand the competitor's commodity price, advertising form, marketing mode, and so on. It can be seen that this operating environment determines the characteristics of perfect competition in e-commerce.


### 5.2. Four Consumption Patterns of E-Commerce and Their Development Measures

The concept part of this study mentioned that the consumption patterns of e-commerce mainly include B2C, B2B, C2C, and O2O. This study investigates and analyzes the development trends of these patterns, as shown in Figure10:Figure 10
Development trends of e-commerce consumption models.As can be seen from Figure10, (e)-commerce has very rapidly developed in recent years, bringing great convenience to people's lives, so it is also very important to promote the development of e-commerce consumption patterns.The main measures to promote the development of e-commerce consumption patterns are as follows.


#### 5.2.1. Adherence to Market Orientation, Supplemented by Government Supervision

Market restrictions play a leading role in the market economy, and this principle also needs to be followed in the development of e-commerce. Defective products do not guarantee quality in e-commerce, which is also the reason for the spontaneity of market restrictions. Therefore, when improving the online shopping environment, it is still necessary to pay attention to the market rules.


#### 5.2.2. Strengthen Research on E-Commerce and Learn from Experience

The development of e-commerce in China cannot be stagnant. This requires e-commerce affiliates to actively participate in international surveys and discussions on e-commerce and learn from relevant experiences in other countries in the discussions. Learning from experience can develop an e-commerce system with Chinese characteristics and lay a foundation for the better development of China's e-commerce.

However, the task of data processing in e-commerce is becoming more and more difficult, so it is necessary to solve this problem through data mining.


## 7. Conclusions

This study mainly discusses how to research the big data mining method of e-commerce consumption pattern based on the mobile platform. This study introduces the importance of studying data mining to the development of e-commerce and then leads to the full text, which fully describes the theoretical knowledge of e-commerce and data mining. In the method part, the association rules and cluster analysis algorithms of data mining are introduced in detail, and the functions of association rules and cluster analysis in e-commerce are analyzed. In the experimental part, this paper first investigates and analyzes the development trend of e-commerce in recent years and also analyzes the trend of consumers' choice. It is found that the promotion activities in e-commerce are welcomed by consumers. Through the survey of consumers, it is found that the advantages of e-commerce mainly include low cost, high convenience, and so on. Finally, the investigation and analysis of the four modes of e-commerce development are carried out, and it is found that the four modes play a great role in e-commerce. Finally, corresponding measures are put forward to promote the development of the four consumption modes. The importance of e-commerce is obvious, so the research on the consumption pattern of e-commerce is quite meaningful.
