## Abstract

In order to improve the willingness of continuous use of mobile social network information services, this study combines user behavior perception to analyze the continuous use of mobile social network information services and proposes a data coverage optimization strategy based on service quality perception. Furthermore, this study measures participants’ regional preferences based on the duration of participants in the perceptual region and the number of historical perceptual tasks completed on the perceptual region. In addition, this study designs a perceptual data coverage optimization algorithm to optimize the perceptual data coverage and ensure the real-time validity of the perceptual data. Through algorithm research and systematic evaluation, it can be seen that the continuous use willingness system of mobile social network information service based on user behavior perception can basically meet the actual needs.

## 1. Introduction

There are many classification methods for mobile location services, including the method of dividing according to whether the positioning is required, the method of dividing according to the service request method, the method of dividing according to the current location positioning, etc. However, by far, the most common method is the classification of mobile location services according to service usage. According to the service usage, mobile location services can be divided into two categories: personal applications and industry applications. Mobile transaction service is based on positioning technology, and users conduct e-commerce transactions through mobile payment. The main mode of mobile location service in the field of industrial applications is to determine the specific location of the user through positioning technology, so as to realize monitoring or scheduling and other work applications. It mainly includes emergency rescue service, vehicle monitoring and dispatching, personnel dispatching, and other functions.LBSNS (location-based social networking service) is a service function project that integrates the two functions of “location” and “social networking.” It can be translated as “mobile location social network service” or “social network location service.” At present, there is no unified translation noun in academic research. The difference between LBSNS and browsing social networking sites anytime and anywhere through mobile clients such as mobile phones is that it highlights the win-win meaning of location and social networking. By determining their location in the software, users can actively publish and share them on social platforms. They can not only find nearby friends by location but also search for discount information of nearby businesses and inquire about the latest activities and services of various businesses that cooperate with social networking sites.This study analyzes the willingness to use mobile social network information services based on user behavior perception and combines the intelligent model to provide a theoretical reference for the follow-up research on the willingness to use mobile social network information services.


## 2. Related Work

In the research field of LBS application mode, scholars have discussed LBSNS from different perspectives: Du Liting analyzed the mode and function of mobile social network services, as well as the communication characteristics from the perspective of communication, to provide research on the development of the commercial value of LBSNS. It has a certain reference significance [1]. Literature [2] studies the development of LBS from the perspective of communication and believes that the integration of LBS and social media exists in two forms: one is a special LBS social networking site and the other is a kind of LBS technology formed by other social networking sites. Social Communication Mode. In the integration process of LBS and network media, the user privacy protection, information authenticity, and market demand still need to be adjusted and avoided [3]. Literature [4] made a detailed analysis of the advantages and disadvantages of LBS interpersonal communication and compared it with the real interpersonal relationship. It was proposed that the LBS interpersonal communication model would lead to prominent alienation, affect normal interpersonal relationships in reality, and reduce real-life interpersonal relationships. Interpersonal skills, increased trust crisis, degraded interpersonal responsibility, and even LBS social interactions will become criminal tools for criminals. Reference [5] puts forward corresponding improvement suggestions to promote the healthy development of LBS interpersonal communication and interpersonal relationships. Another research perspective is to explore LBS from the perspective of business services. Literature [6] proposes that location-based business information services have quietly emerged in China, and how to connect businesses with the needs of surrounding consumers is a solid foundation for the development of LBS. Reference [7] provides insights and predictions on the future development trend of LBSNS by studying the information acquisition, sharing, privacy protection of social network location services, and user identification and location recognition. Literature [8] analyzes the feasibility of applying LBS to the group buying industry and discusses the existing problems and suggestions for improvement of the group buying website based on LBS. Literature [9] summarizes and analyzes the mobile e-commerce marketing model based on LBS based on relevant cases in the field of mobile e-commerce and predicts the development trend of mobile e-commerce based on LBS. Literature [10] proposed the prospect of mobile development of LBS business and the strategy of LBS application innovation through the SWOT analysis model and carried out a simple LBS system planning and design for the industrial application of LBS personal products with practical needs. Reference [11] builds an LBS group buying business adoption model and verifies the hypothesis that perceived trust, perceived usefulness and ease of use, and network externalities are important factors that affect the willingness to use LBS group buying. Literature [12] uses theoretical analysis tools and data analysis reports of mobile operators and consulting companies to analyze and study the development status, influencing factors, profit models, and development trends of the LBS industry, promotes the development of the LBS industry, and provides suggestion on characteristics of electronic services.There are not many studies on user behavior in my country. Scholars have studied the development of LBS from the user’s perspective through different theoretical perspectives and discussed it in depth. Reference [13] evaluates the importance of specific quality elements from the perspective of user perception and proposes priority improvement directions for operators. Literature [14] put forward four hypotheses about the attitude and behavior of LBS information users and obtained relevant conclusions by sending out questionnaires to college students to collect data and analyze them. Literature [15] introduces the theory of self-construction, proposes a model of self-construction for users to accept mobile location services, and verifies it; Literature [16] uses social capital theory to analyze the impact of LBS’s interpersonal communication on individual network capital, information capital, credit capital, emotion, and influence of capital. Reference [17] introduces influencing factors such as individual conformity into the original model of TAM users, builds a new hypothesis model, verifies the hypothesis, and puts forward suggestions for the development of the mobile location service industry. Reference [18] combines information system success theory. Combined with the information system success theory, the influence of information quality and system quality on perceived usefulness and ease of use is proposed, and a new research model of influencing factors of mobile location service usage intention is constructed. Literature [19] researches and analyzes users’ consumption patterns from the perspective of location data and completes an intelligent system that integrates event detection, event prediction, and estimation of the number of customers. Reference [20] studies the user check-in data of LBSNS, analyzes and predicts the user behavior from the aspects of space, time, and social interaction, and establishes a location prediction model by using the main factors that affect the user’s mobile behavior obtained by the study.


## 3. Social Network Information Service Based on User Behavior Perception

The perceptual data coverage optimization process is shown in Figure1.Figure 1
Optimization process of data coverage.Participants collect perception data according to their own will. If the willingness of the participants is low, it means that the enthusiasm of the participants to perform the perception task is not high. Obviously, the service quality of the participants is low at this time, so it is necessary to measure the willingness of the participants. We assume that the set of participants isN=n1,n2,…,nr. Considering that MCS is often used in scenarios with strong real-time and high complexity, we assume that S=s1,s2,…,sj is the set of perception tasks divided by the platform according to factors such as time and geographic location. In addition, if we assume that participant ni performs perception task sj, then the start time of perception task sj is tsj, the end time is tej, and tej−tsj is the perception period of task sj. If ni starts to perform perception task sj at a time of tij, then obviously the value range of tij is tsj,tej, and the decision time hij of ni to perception task sj is tij−tsj. If the time tij at which ni starts to perform the perception task is closer to the start time tsj of the perception task, then ni is more motivated to perform the perception task, thus having a higher degree of willingness. In addition, there may be a one sidedness in measuring participants’ willingness by a single factor, so the remaining battery power of participants’ mobile devices is also considered here. If the remaining power value Vir of the mobile device of the participant ni is larger, then ni has more willingness to perform the perception task without affecting the use of the mobile device, and the higher is the willingness of ni at this time. Therefore, the willingness of the participants to perform the perception task sj can be measured according to the participant’s decision time hij for the perception task sj and the remaining power Vir of the mobile device. When the participant starts to perform the perception task at the same time as the start time of the task, the decision time hij of ni to sj at this time is 0, which means that the participant performs the task immediately when the task starts. Therefore, the willingness Wij of the participants can be judged to be 1. To sum up, the quantification method of participants’ willingness Wij is shown in formula (1):(1)Wij=minVirVia⋅hij∑i=1vhij/v,1hij≠0,1,hij=0.Among them,Via represents the total power of the mobile device, v represents the total number of participants performing the perception task sj, and hij/∑i=1vhij/v represents whether the decision time of participant ni for sj is lower than that of other participants.Considering the temporal and spatial characteristics of the participant’s movement trajectory, the participant’s regional preference is not only related to the number of times the participant performs the perceptual task at the same regional location but also to the duration of the participant’s perceptual task at the regional location. We assume that the region location of perceptual tasklj is sj. In the historical perception task list of participant ni, if ni performs perception tasks at regional location lj more times and the duration of the task is longer, then participant ni has a greater preference for regional location lj. Moreover, the next time the perception task of the regional location lj is performed, the more the real-time validity of the perception data can be guaranteed, and the higher the service quality of the participant ni at this time. If participant ni is performing the perception task for the first time, then the historical perception task list of ni is empty at this time, so the platform sets the regional preference of ni to 0, indicating that ni has no regional preference.If history-aware task list ofni is nonempty, then in the history-aware task, the more times lj performs the perception task, and there is the longer the duration of staying at the region location lj during the execution of the perception task. At this time, it means that the regional preference Rilj of the participant is larger. The participant’s regional preference Rilj is measured in terms of the number of times the participant performed the perceptual task at lj and the duration of the perceptual task performed. In addition, considering that the number of times ni performed perceptual tasks in lj, the duration of performing perceptual tasks has different degrees of influence on participant ni's regional preference Rilj, and the calculation method of Rilj is as follows:(2)f1ilj=OiljOi,f2ilj=∑oiljgilj−yilj∑oiljeilj−silj,Rilj=α1ljf1ilj+α2ljf2ilj.Among them,f1ili and f2ilj represent the number of times ni performs the perception task and the duration of the perception task at lj, respectively, and Oili is the number of times that ni performs the perception task at the regional location lj. Oi is the total number of times the participant performs the perceptual task, and yili and gilj are the time when ni starts and ends the perceptual task in the regional location lj, respectively. sili and eilj are the start time and end time of the perception task at region location lj, respectively. In addition, the weight α1lj represents the degree of influence of f1ilj on Rilj, α2lj represents the degree of influence of f2ili on Rilj, and α1lj+α2lj=1.In order to objectively reflect the influence off1ili and f2ili on Rilj, this section uses the entropy weight method to calculate αglj,g=1,2. At the same time, considering the difference in data dimension and order of magnitude between f1ili and f2ili, it may bring errors in the calculation of αglj. Therefore, we first normalize f1ili and f2ili, as shown in the following formula:(3)fgili˜=fgilj−μgljσglj,g=1,2,i=1,2,…,ϕ.Among them,ϕ is the number of participants who have performed perception tasks at regional location lj in historical perception activities, and ϕ⊆N. In addition, μglj and σglj represent the mean and standard deviation of fgilj,g=1,2, respectively, as shown in the following formula:(4)μglj=∑i=1ϕfgiljϕ,σglj=∑i=1ϕfgilj−μglg2ϕ−1,g=1,2.Second, in order to obtain the information entropy offgilj, first, according to formula (3), the proportion φsilj of fgili after normalization can be obtained, that is, φgili=fgil˜l˜/∑i=1ϕfgil˜. Then, the information entropy Hglj of fgili is obtained according to φgilj, as shown in the following formula:(5)Hglj=∑i=1ϕφgiljlnφgitj−lnϕ.Finally, the weight offgili is obtained according to the entropy weight βglj, corresponding to the information entropy Hglj of fgili, as shown in the following formula:(6)βglj=1−Hglj∑g=121−Hglj,αglj=βglj∑g=12βglj.The higher the willingnessWij of ni, the more actively ni participates in the perception task, and the more effectively the real-time perception data can be guaranteed. At this time, the service quality Mi of ni is larger, so the willingness degree Wij of ni is proportional to Mi, that is, dMi/dWij>0:(7)Mi=log2WijmaxWij+1,∀ni∈N.If participantni is not performing the perception task for the first time, then the service quality Mi of ni needs to be measured according to its willingness and regional preference, so the service quality of ni is as follows:(8)Mi=log2WijmaxWij⋅RiljmaxRili+1,∀ni∈N.We assume that in each perception task, participants need to submit dataQ=1,2,⋯,q times. Participants only need to go to the corresponding target points to collect perception data. In addition, in actual situations, the amount of perceptual information provided by the target points is not the same, so it is assumed that ωPj=ω1,ω2,…,ωp is the weight of Pj, and ω1+ω2+⋯+ωp=1. Obviously, when the participant ni has not yet started to perform the perception task sj, the value of Csjqni is 0 at this time. When ni starts to perform perceptual task sj, as the number of target points covered by ni's perceptual data increases, the perceptual coverage also increases. Therefore, the perceptual data coverage of participant ni’s q-th submission is shown in the following formula:(9)Csjqni=∑ωmimiPj.Among them,mi is the number of target points contained in the data perceived by participant ni, and ωmi⊆ωPj.We assume that the setλ,λ⊆N of participants f submits perceptual data about task sj for the q-th time. If the perception data submitted by participants ni and nj contain the same target points, then the same target points are considered only once when calculating the perception data coverage. Therefore, the coverage of the participant set λ is shown in the following formula:(10)Csjqλ=1Pj∑ωejej+∑ωyjyj,∀ωej,ωyj∈ωP,∀ej,yj∈Pj.Among them,ej represents the same target point in the participant set λ and yj represents different target points.We assumeUsjχ to be the platform’s satisfaction. If the difference between Csjχ and δsj is small, then the value of Usjχ is large. In addition, since Csjχ and δsj are represented in the form of matrices, this section uses the Frobenius norm to quantify the difference between Csjχ and δsj to evaluate the satisfaction Usjχ, as shown in the following formula:(11)Usjχ=1−δsj−CsjχFδsjF.Among them,⋅F represents the Frobenius norm.It can be seen from the above that the platform not only needs to optimize the coverage of perception data. It is assumed that the utility of participantni is ζsjni. If the utility value ζsjni of ni is high, then the participant ni not only guarantees the real-time validity of the perception data but also the coverage rate of the perception data when performing the perception task.(12)ζsjni=Mi⋅Usjχ+ni−Usjχ.Among them,Usjχ+ni−Usjχ represents the satisfaction of the participant ni with the platform. If the satisfaction is high, then the perceptual data coverage of ni is high.We assume that the platform selects the perception data of the participant setS=s1,s2,...,sj for the perception task set χ∗. In order to maximize the utility of the participant set χ∗, this section first defines the perceptual data coverage optimization problem, as shown in the following formula:(13)Maximize:ζχ∗=ζs1χ∗,ζs2χ∗,⋯,ζsjχ∗T,subject to:χ∗⊆N;∑i∈χ′fi≤J.When the utility ofζs,χ∗ increases, it needs to receive the perception data of more participants, so that formula (13) is converted into the following formula:(14)Maximize:ζχ∗=∑j=1jPj∑j=1jPjζsjχ∗,subject to:χ∗⊆N;∑i∈χ′fi≤J.Among them,Pj/∑j=1jPj is the proportion of perception task sj. It will obviously affect the platform to select the number of participants’ perception data, thus affecting the coverage of perception data. Therefore, according to the participant’s utility and reward, the platform selects the participant’s perception data with the highest reception efficiency in each iteration, and the efficiency ϑni,χ∗ of participant ni is shown in the following formula:(15)ϑni,χ∗=∑j=1jPj/∑j=1jPjζχ∗+ni−∑j=1jPj/∑j=1jPjζχ∗fi.It can be seen from the above formula that if the reward of the participantni is higher, it will obviously affect the growth of the efficiency ϑni,χ∗.The proposed DCSQ strategy is validated by MATLAB, and the DCSQ strategy is compared with the IMRA strategy and the CrowdTasker strategy under different number of participants and different budgets. At the same time, the coverage rate, total perception time, and participants’ total reward parameters under the three strategies are analyzed.Figure2 analyzes the effect of changes in perceived data coverage when the number of participants changes.Figure 2
Perceptual data coverage.In Figure3, it can be seen that with the increase in the number of participants, the total reward of participants changes according to the law of rapid growth at first and then almost stable. Compared with the CrowdTasker strategy, the DCSQ strategy also considers the real-time validity of the participants’ perception data, so the total reward of the participants in the DCSQ strategy is the smallest.Figure 3
Total rewards for participants.Figure4 compares the changes in the total perception time of the task for different numbers of participants.Figure 4
Total perception time.The total reward of participants and the total perception time under different platform budgets are shown in Figures5–7. Among them, Figure 5 reflects the changes in the perceived data coverage of the three strategies under different platform budgets. As the platform budget increases, the perception data coverage increases to a certain level and then remains stable.Figure 5
Coverage.Figure 6
Total rewards for participants.Figure 7
Total perception time.In Figure6, the total reward of participants increases first and then stabilizes as the platform budget increases. The reason is that as the platform budget increases, the platform chooses to receive more participant perception data. In Figure 7, as the platform budget increases, the total perception time first decreases and then slowly stabilizes.


## 4. Continuous Use Intention of Mobile Social Network Information Service Based on User Behavior Perception

Information quality, service quality, and system quality all have an impact on satisfaction. Therefore, in this study, the relationship between its two-dimensional variables and satisfaction is constructed. Because the information quality, system quality, and service quality are used as specific objective influencing variables to describe the user’s postuse expectation, the expectation confirmation variable is deleted. The constructed user continuation intention model is shown in Figure8(a).Figure 8
Continuous use intention of mobile social network information services based on user behavior perception (a) Continuous use intention model of user. (b) Personalized service continuous use intention model.
(a)(b)From the perspective of user behavior perception, based on the ECM-ISC model, this study combines hedonic theory and herd theory to take perceived pleasure, imitating others, and not fully believing in the information they have as model variables. Moreover, this study introduces habit as a moderating variable between continuous use intention and behavior and constructs a continuous use model of mobile Internet-personalized service based on user behavior perception (Figure8(b)). The model consists of two parts: the willingness model for continuous use of mobile Internet-personalized services and the model for continuous use behavior. In addition, it takes continuous use intention and continuous use behavior as dependent variables to study the effects of perceived pleasure and herding behavior on continuous use intention and the mechanism of user habits on continuous use intention and continuous use behavior.On the basis of the above research, the continuous use intention of mobile social network information service based on user behavior perception is studied, and the effectiveness of the model in this study is calculated. The results are shown in Table1. and Figure 9.Table 1
