## 1. Introduction

With the development of electronic technology and mobile communication technology in China, most college students can easily use computers to access the Internet, and almost all of them use cell phones, and using cell phones to access the Internet is very common in colleges and universities [1]. The Internet brings college students into a wonderful virtual world, in which they can understand the culture of the world and grasp the current world events [2]. The means and methods are more modern and diversified, the form and content are more attractive, the effect is more obvious, and the ideological and political education workers can more easily understand the real college students’ ideological dynamics and psychological problems [3][4].Ideological and political education, as a discipline closely combining theory with practice, has always been the focus of academic attention and the forefront of research. At present, network technology is developing rapidly. By studying the development trend of network ideological and political education, this study aims to put forward some theoretical thinking on how to carry out ideological and political education, so as to guide practice more effectively [5].In recent years, location-based social networks have developed rapidly and attracted more and more users. Point of interest recommendation has been widely studied in location-based services and recommendation systems [6]. Among these methods, the collaborative filtering method based on user similarity is not only efficient but also has good recommendation performance, so it is often used by service providers. In the point of interest recommendation, the item set is the point of interest in the system. The user login record constitutes the user’s evaluation matrix for the item. The elements in the evaluation matrix represent the user’s access times or evaluation values for the corresponding point of interest [7].In the real society, time factor plays a very important role in people’s daily life. In lbsn, the time characteristics of user behavior are included in the time records of user access points of interest. Therefore, the time characteristics of user behavior can be found by analyzing user check-in records and using them to recommend points of interest to users [8]. For example, if many people go to the bar at midnight and only a small number of people go to the library at this time, the weight of the bar is greater than that of the library when recommending points of interest to users. In lbsn, in order to further analyze the importance of temporal features in user interest point recommendation, a temporal feature-oriented interest point recommendation algorithm is proposed.


## 2. Related Work

According to the author’s search, there is no monograph on online ideological [9]. For example, the approach and methods adopted are different from the explicit approach in China, which is the implicit education approach. The authors of [10] discuss the recent status of various aspects of educational research and development in the United States, with specific science as the main line, make a more in-depth review of the frontier hotspots, and present in detail the research development of educational theory in the United States as well as the challenges and development trends and main measures faced by ideological and political education in the United States in recent years.For the research related to the network and ideological and political education, the authors of [11] regard the network as a cyberspace corresponding to the physical space, a completely simulated environment, and a virtual real world, and the main research involves the influence of the network on people’s ideology, way of thinking, value orientation, psychological and behavioral styles, and social market. The authors of [12] argue that colleges and universities, because of the existence of the network, thus making ideological education with high cultural and technological content, can implicitly include the essence of ideological education content in various cultural knowledge and technological information knowledge, so that students can be inculcated and infected in a subtle way.The authors of [13] have conducted a more systematic research work on the online Internet, and people began to study network culture and its influence on ideological and political education from various different perspectives, such as communication, education, political science, and sociology. The authors of [14] focus on the relationship between network culture and college students from the perspective of communication science, and the theoretical research results are quite rich. The authors of [15] systematically expound the opportunities and challenges brought by the network culture to emphasize the necessity of combining “rule by law” and “rule by morality” [16, 17].Regarding the research on countermeasures to strengthen ideological and political education in the network environment, scholars have proposed response strategies from different perspectives to provide theoretical guidance. The authors of [18, 19] believe that under the influence of new media such as the Internet, the traditional indoctrination mode of ideological and political education has obviously failed to keep up with the development of the times, and it is necessary to innovate educational concepts, focus on ideological guidance, and build an interactive platform. In his doctoral dissertation, the authors of [20] proposed five methods in the context of globalization, such as combining indoctrination with two-way communication, explicit education with implicit education, differentiating levels and teaching according to the material, optimizing information and practicality, and spiritual communication and mutual feeling of ideas.


## 3. Opportunities in the Network Environment

### 3.1. Breakthrough of Ideological and Political Education in Time and Space

Traditional ideological and political education is often restricted by time, place, venue, and language and is a kind of “face-to-face” education. In contrast, online ideological and political education has broken the limitations of time and space, and students no longer have to be restricted by time and place to receive education. No matter teachers as educators or college students as educated people, as long as they have a connected network and a computer, they can go online 24/7 to publish and get all kinds of information; no matter where they are, they can learn about the political, economic, and cultural situations happening at home and abroad through the network; college students from different countries, different regions, and different universities can share resources through the network, and students from different countries, regions, and universities can share resources, consult on problems, and exchange study experience.


### 3.2. Enrichment of Ideological and Political Education Contents

The traditional ideological and political education contents are chosen by educators according to the established cultivation goals and programs, some of which are monotonous and old-fashioned; influenced by the limitation of the traditional media of accommodating little information and the insufficient knowledge reserve of ideological and political education workers themselves, the amount of information received by college students is relatively small and cannot meet the needs of college students’ growth and success.


### 3.3. Strengthening the Relevance

Because the network is virtual, equal, and anonymous, many college students can leave behind the constraints and worries of reality in the network world, open their hearts, and reveal their real inner world, and ideological and political education workers can understand students’ ideological dynamics and interests more realistically and accurately through students’ QQ space, microblog space, and WeChat messages, so as to carry out targeted individual ideological education or formulate targeted education policies. At the same time, through the network, it also shortens the psychological distance between teachers and students, and the things that college students cannot say in person can be boldly revealed to teachers online; teachers can also put down the “teacher” frame, and discuss with students in a more close to life, witty, and humorous language, and become friends with students, so the interaction greatly improves the effectiveness of education. This interaction greatly improves the effectiveness of education.

## 4. Recommendation Algorithms Combining Spatio-Temporal Features

### 4.1. User-Based Collaborative Filtering Method

In predicting the probability of a user’s visit to a certain point of interest, the user-based collaborative filtering method first calculates the similarity between the user and other users based on the sequence of the user’s point of interest visits, then selects a number of most similar users, and weights the sum of the visit record values of these similar users to the specified point of interest.LetU be the set of users, L be the set of interest points, and the user’s access matrix to interest points be c, where user cu,l=1 means that user u∈U has accessed interest point l∈L and cu,l=0 means that u has not accessed interest point l. Given user u, if the user has not accessed interest point l, then the probability that u will access l in the future is(1)c^u,l=∑twu,vcv,l∑rwu,v.In equation (1), the similarity weight between users can be derived by various methods, and in this paper, we apply cosine similarity to calculate the similarity of the check-in records between two users. For users v and u, the formula for calculating the cosine similarity is(2)wu,v=∑lcu,lcv,l∑lcu,l2∑lcv,l2.


### 4.2. Introducing Temporal Features

In this paper, time is divided into equal time segments, and each time segment is one hour. Therefore, the user’s behavior can be represented as the user’s visit to a specific interest point in a specific time slice, that is, the check-in information. In order to represent the temporal characteristics of the user’s check-in behavior, this paper introduces a temporal dimension to the traditional user-a-point-of-interest check-in matrix, that is, a three-dimensional cube composed of user ∼ time ∼ point-of-interest. In this three-dimensional cube, each elementcu,t,l represents the behavior of user u about interest point l at time segment t. cu,t,l=1 means that u has visited l at t, and cu,t,l=0 means that u has not visited l at t.To consider the role of temporal features in interest point recommendation, the collaborative filtering method of equation (1) is modified as follows: (a) includes temporal features in calculating the similarity between users; (b) applies the user’s check-in records on a time slice instead of all check-ins on the timeline in the recommendation process. Given a user u and a time segment t and an interest point l that has not been visited, the probability that the user visits the interest point l is as follows:(3)c^u,t,l=∑lwu,ttcv,t,l∑xwu,rt,where wu,tt is the temporal similarity of users u,v at time segment t. After considering the temporal characteristics, the cosine similarity shown in equation (2) is expressed as(4)wu,tt=∑t=1T∑l=1Lcu,t,l×ct,t,l∑t=1T∑l=1Lcu,t,l2∑t=1T∑l=1Lcr,t,l2.


### 4.3. Introducing Spatial Features

The literature [2] shows that the geographical location of interest points largely influences users’ check-in behavior. Based on the analysis of the relationship between users’ check-in behavior and distance, this paper concludes that users prefer to visit those interest points near the interest points they have visited before, and this tendency decreases with the increase of the distance of candidate interest points.In order to introduce spatial features in interest point recommendation, this paper uses power rate distribution to represent the relationship between users’ tendency to visit interest points and the distance between interest points and known interest points. Letdis be the distance of the interest point to be estimated, and a and k be the parameters of the power rate distribution, respectively, and then, the propensity of the user to visit the interest point can be calculated by the following equation:(5)widis=a⋅disk.In this paper, we apply the great likelihood estimation method to estimate the parametersa and k in equation (5). Taking logarithms of both sides of equation (5) yields the following equation:(6)lnwidis=lna+klndis.Let the user’s current interest point beli and the distance between the candidate interest point li,lj and lj be disli,lj, then the conditional probability plj|li that the user visits lj in the next time segment is the proportion of the user’s propensity to visit interest point lj to all interest points, which is defined as shown in the following equation:(7)plj|li=widisli,lj∑lk∈L,lk≠liwidisli,lk.Equation (5) shows that as the distance of the point of interest increases, the user’s propensity to visit the point of interest decreases; as the user’s propensity to visit the point of interest decreases, the conditional probability of the user visiting the point of interest shown in equation (7) also decreases. Thus, it can be assumed that the probability of a user visiting a distant interest point is small. Given a user u and its historical check-in records Lu, the conditional probability of that user visiting l in the next time segment can be obtained based on Bayes’ rule as Pl|Lu.(8)c^u,ls=Pl|Lu∝PlPLu|l=,Pl∏l′∈LuPl′|l.

Given user u, if the user has not accessed interest point l, then the probability that u will access l in the future is(1)c^u,l=∑twu,vcv,l∑rwu,v.In equation (1), the similarity weight between users can be derived by various methods, and in this paper, we apply cosine similarity to calculate the similarity of the check-in records between two users. For users v and u, the formula for calculating the cosine similarity is(2)wu,v=∑lcu,lcv,l∑lcu,l2∑lcv,l2.

The experiments compare the algorithm proposed in this paper with other related algorithms. The interest point recommendation algorithm for temporal features proposed in this paper is denoted as UTE + SE and user-based collaborative filtering algorithm considering spatial features (U + SB).


### 5.2. Experimental Results

We can see the scores of the subjects in the three dimensions of political socialization in Table1. By converting the average score percentage, we can better understand and compare them. We can see that the average score of the students’ political knowledge is 75.5, and the average correct answer to the political and current affairs questions is 81.5%; the average correct rate of answering questions about political system knowledge was 71.68%. This is closely related to China’s good and systematic education level.Table 1

The higher the frequency of Internet use, the greater the impact of network communication on them, and the more obvious the political socialization function of network media. According to the actual situation, college students are divided into three classes according to the frequency of surfing the Internet: low-frequency Internet users who surf the Internet less than or equal to 1 day a day, medium-frequency Internet users who surf the Internet 2–3 days a week, and high-frequency Internet users who surf the Internet more than 4 days a week. The percentage of college students with different surfing frequencies is shown in Figure1.Figure 1
The proportion of college students with different Internet access frequencies.According to statistics, among the 550 valid questionnaires collected, 20 (3.64% of the total) used low-frequency Internet, 91 (16.55% of the total) used medium frequency Internet, and 439 (79.81% of the total) used high-frequency Internet. It can be seen that the number of high-frequency Internet users accounts for the vast majority of college students, which indicates that this group has a high Internet utilization rate.In this survey, we studied the political socialization of college students in the network environment. Information exchange, communication, entertainment, and frequent Internet access are not necessarily for browsing political information. Therefore, it is not comprehensive to only consider the Internet access frequency in the analysis. In the questionnaire, two questions were added: “how often do you browse the political information on the Internet.” Only 17.7% of college students chose “never,” “4–5 days a week,” and “every day.” The number of people who choose “4–5 days a week” and “every day” is as high as 34.55%; the results of the question “how many times do you participate in online political discussions” show that more than 60% of the people have never participated in online political discussions, and 7.27% of the people have participated in online political discussions. 7.27% of college students have participated in it for 3–4 times, which indicates that college students often study political information online, but the proportion of real political participation is low, indicating that the high frequency of Internet access and the socialized function of the Internet have a certain impact on them.In the specific measurement of the impact of the Internet on various dimensions, the frequency of Internet access was used as a single factor, and the frequency of Internet access frequency as a single factor and the frequency of Internet access as the independent variable, the differences in political knowledge, political value tendency, and political participation tendency of Internet users with different frequency of Internet access were measured. The results are shown in Table2.(1)
The relationship between the frequency of Internet access and the level of political knowledge is shown in Figure2.Table 2

Comparison of mean scores of political knowledge among people with different frequencies of Internet access.College students learn rich political knowledge and accelerate the process of their own political socialization through the political information obtained and disseminated through the Internet. The above figure shows that people with different frequencies of Internet users have different effects on political knowledgeM1>M3>M2, and in terms of the total mean score of political knowledge, those with higher frequencies are 0.48 points higher than those with lower frequencies.The mean scores of the two subcategories of basic political institutional knowledge and current affairs are higher for those with high frequency of Internet access than those with low frequency of Internet access, 0.2 and 0.28 points higher, respectively. From the findings, we can see that the use of the Internet has improved the level of political knowledge of the subjects, but the difference is not significant.The above situation occurs for the following reasons, in my opinion.First, the Internet, because of its own characteristics, can quickly and conveniently provide rich political information and a wide range of political culture, and those who go online frequently have the opportunity to get more updated political knowledge.Second, due to the systematic ideological and political education system in China, college students have received a good education from childhood to adulthood. In addition, they have acquired certain political knowledge through communication with peer groups and reading traditional media; therefore, there is not much difference in the scores of political knowledge among different groups with different Internet access frequency in the Internet environment.(2)
The relationship between the frequency of Internet access and political value tendency is shown in Figure3.Figure 3
Comparison of the mean scores of political value tendency among people with different Internet access frequencies.From the above figure, it can be seen that there is a significant difference in the political value tendency of different Internet access frequency groups, and the score of high-frequency Internet users is only 38.3, which is lower than the scores of low and medium frequency Internet users, so it can be seen that the political values of high-frequency Internet users are more deviated from the mainstream direction of society. The scores of high-frequency Internet users are significantly lower than those of other Internet users in all five categories except for the subcategory of national identity. The use of the Internet tends to have a negative impact on the political values of high-frequency Internet users.I believe that the above situation occurs for the following reasons.First, the network information is mixed, and the network itself is confidential, open, and autonomous. Compared with the positive publicity of traditional media, netizens can evaluate the current government in various forms. If college students are exposed to this negative information for a long time and lack mature political judgment, it will inevitably lead to a reduction in their recognition of the government.Second, people with high Internet frequency are dependent on the use of the Internet and over-dependent on the Internet environment, their political thinking ability is weakened, they lack rational judgment on political events and are prone to impulse, and their political rationality scores are low, which shows this problem.Third, the sovereignty of Internet information is in the hands of western countries. Long-term access to Internet information is easy to be confused by some superficial things, resulting in ideological confusion. While Western values and concepts are widely spread, college students with high frequency of Internet access are easily affected by these values and concepts.Fourth, a healthy network culture is conducive to the improvement of college students’ ideological and political levels. Groups with different Internet access frequencies do not have the same problems as those studied by previous scholars: “in the Internet environment, diversified political culture and virtual political activities often lead to the expansion of individual liberalism and the weakening of national consciousness in the process of political socialization of young people,” while groups with high Internet access frequency score higher in the national identity subitem than those with low or medium Internet access frequency. It can be seen that the network environment does not affect the patriotic enthusiasm of college students, but it is easy to stimulate a stronger sense of patriotism and national consciousness.(3)
The relationship between the frequency of Internet access and the tendency of political participation is shown in Figure4.Figure 4
Comparison of the mean scores of political participation tendency among people with different frequencies of Internet access.The Internet not only provides an exchange platform for college students’ political participation but also brings diversified online information to college students. Whether the high frequency of surfing the Internet will affect the political participation tendency of college students? From the survey results, it can be seen that the total score of political participation tendency of college students with a high frequency of surfing the Internet is lower than that of other college students with a high frequency of surfing the Internet. In the subcategories of political participation tendency, such as political efficacy, participation attitude, civic awareness, and expression, the score is slightly lower than that of the low and middle Internet users. It can be seen that the use of the Internet has a negative impact on those who surf the Internet more frequently, while those who surf the Internet more frequently have a less positive attitude towards political participation, poor political efficiency, and poor understanding of civil rights and biased expression.

In the questionnaire, two questions were added: “how often do you browse the political information on the Internet.” Only 17.7% of college students chose “never,” “4–5 days a week,” and “every day.” The number of people who choose “4–5 days a week” and “every day” is as high as 34.55%; the results of the question “how many times do you participate in online political discussions” show that more than 60% of the people have never participated in online political discussions, and 7.27% of the people have participated in online political discussions. 7.27% of college students have participated in it for 3–4 times, which indicates that college students often study political information online, but the proportion of real political participation is low, indicating that the high frequency of Internet access and the socialized function of the Internet have a certain impact on them.In the specific measurement of the impact of the Internet on various dimensions, the frequency of Internet access was used as a single factor, and the frequency of Internet access frequency as a single factor and the frequency of Internet access as the independent variable, the differences in political knowledge, political value tendency, and political participation tendency of Internet users with different frequency of Internet access were measured. The results are shown in Table2.(1)
The relationship between the frequency of Internet access and the level of political knowledge is shown in Figure2.Table 2

Comparison of mean scores of political knowledge among people with different frequencies of Internet access.College students learn rich political knowledge and accelerate the process of their own political socialization through the political information obtained and disseminated through the Internet. The above figure shows that people with different frequencies of Internet users have different effects on political knowledgeM1>M3>M2, and in terms of the total mean score of political knowledge, those with higher frequencies are 0.48 points higher than those with lower frequencies.The mean scores of the two subcategories of basic political institutional knowledge and current affairs are higher for those with high frequency of Internet access than those with low frequency of Internet access, 0.2 and 0.28 points higher, respectively. From the findings, we can see that the use of the Internet has improved the level of political knowledge of the subjects, but the difference is not significant.The above situation occurs for the following reasons, in my opinion.First, the Internet, because of its own characteristics, can quickly and conveniently provide rich political information and a wide range of political culture, and those who go online frequently have the opportunity to get more updated political knowledge.Second, due to the systematic ideological and political education system in China, college students have received a good education from childhood to adulthood. In addition, they have acquired certain political knowledge through communication with peer groups and reading traditional media; therefore, there is not much difference in the scores of political knowledge among different groups with different Internet access frequency in the Internet environment.(2)
The relationship between the frequency of Internet access and political value tendency is shown in Figure3.Figure 3
Comparison of the mean scores of political value tendency among people with different Internet access frequencies.From the above figure, it can be seen that there is a significant difference in the political value tendency of different Internet access frequency groups, and the score of high-frequency Internet users is only 38.3, which is lower than the scores of low and medium frequency Internet users, so it can be seen that the political values of high-frequency Internet users are more deviated from the mainstream direction of society. The scores of high-frequency Internet users are significantly lower than those of other Internet users in all five categories except for the subcategory of national identity. The use of the Internet tends to have a negative impact on the political values of high-frequency Internet users.I believe that the above situation occurs for the following reasons.First, the network information is mixed, and the network itself is confidential, open, and autonomous. Compared with the positive publicity of traditional media, netizens can evaluate the current government in various forms. If college students are exposed to this negative information for a long time and lack mature political judgment, it will inevitably lead to a reduction in their recognition of the government.Second, people with high Internet frequency are dependent on the use of the Internet and over-dependent on the Internet environment, their political thinking ability is weakened, they lack rational judgment on political events and are prone to impulse, and their political rationality scores are low, which shows this problem.Third, the sovereignty of Internet information is in the hands of western countries. Long-term access to Internet information is easy to be confused by some superficial things, resulting in ideological confusion. While Western values and concepts are widely spread, college students with high frequency of Internet access are easily affected by these values and concepts.Fourth, a healthy network culture is conducive to the improvement of college students’ ideological and political levels. Groups with different Internet access frequencies do not have the same problems as those studied by previous scholars: “in the Internet environment, diversified political culture and virtual political activities often lead to the expansion of individual liberalism and the weakening of national consciousness in the process of political socialization of young people,” while groups with high Internet access frequency score higher in the national identity subitem than those with low or medium Internet access frequency. It can be seen that the network environment does not affect the patriotic enthusiasm of college students, but it is easy to stimulate a stronger sense of patriotism and national consciousness.(3)
The relationship between the frequency of Internet access and the tendency of political participation is shown in Figure4.Figure 4
Comparison of the mean scores of political participation tendency among people with different frequencies of Internet access.The Internet not only provides an exchange platform for college students’ political participation but also brings diversified online information to college students. Whether the high frequency of surfing the Internet will affect the political participation tendency of college students? From the survey results, it can be seen that the total score of political participation tendency of college students with a high frequency of surfing the Internet is lower than that of other college students with a high frequency of surfing the Internet. In the subcategories of political participation tendency, such as political efficacy, participation attitude, civic awareness, and expression, the score is slightly lower than that of the low and middle Internet users. It can be seen that the use of the Internet has a negative impact on those who surf the Internet more frequently, while those who surf the Internet more frequently have a less positive attitude towards political participation, poor political efficiency, and poor understanding of civil rights and biased expression.


## 6. Conclusion

In order to further improve the performance of the interest point recommendation algorithm, this paper proposes a temporal feature-oriented interest point recommendation algorithm and gives a basic user-based collaborative filtering method to fuse temporal and spatial features. Experiments show that the proposed algorithm has significantly higher accuracy and recall compared with other related algorithms and is therefore more suitable for interest point recommendation services.
