## 1. Introduction

The research on the adaptive recommendation technology of intelligent teaching resources under the school enterprise cooperation mode plays a vital role in the efficient presentation and accurate acquisition of teaching resources. At present, the representative technologies of how to improve the intelligence of resource acquisition at home and abroad mainly include automatic word segmentation, data mining, collaborative filtering, and genetic algorithm [1]. As a key technology and basic work in information processing such as text classification, information retrieval, and information filtering, automatic word segmentation has always been a research hotspot in the field of information retrieval. Relevant scholars have proposed many automatic word segmentation algorithms, which can be roughly summarized as dictionary word segmentation method, statistical word segmentation method, understanding word segmentation method, and combination word segmentation method [2]. Among them, the dictionary word segmentation method is more mature and easy to implement. Due to the complexity and flexibility of natural language and the difficulty of knowledge representation in information resource description, it is often necessary to combine with other technologies to improve the retrieval accuracy in practical application. In view of the low accuracy and personalized service of the query and feedback results of teaching resources, this paper designs an adaptive recommendation model of teaching resources based on the school enterprise cooperation mode, which makes the model more intelligent, provides personalized services for users, and dynamically adjusts and presents the retrieval content of teaching resources [3]. We investigate the use of artificial intelligence (AI) and Internet of Things (IoT) technologies in ideological and political classroom education and intelligent educational systems based on real-world educational conditions to improve the efficiency of ideology and to build an education in the political classroom.


## 2. Adaptive Recommendation of Online Ideological and Political Teaching Resources

### 2.1. Collection and Management of Online Ideological and Political Teaching Resources

During the time spent building recommendation strategies, assuming there is model direction, it will come by two times the outcome with around 50% of the work. Be that as it may, there is no framework model for customized recommendation of learning resources in the field of education [4]. The customized recommendation procedure for learning resources can be viewed as the particular utilization of the recommendation framework in the field of education and a versatile learning framework. Hence, the general model of the recommendation framework and the general model of the versatile learning framework can give a reference. In any case, the general model of recommendation framework is basically focused on the business field and cannot be completely pertinent to the customized recommendation of learning resources [5]. The general model of versatile learning framework covers a wide reach, is not explicitly for the recommendation framework, and cannot completely address the issues. Subsequently, after top to bottom investigation of the important speculations and innovations of customized education and recommendation framework, this paper proposes a customized learning resource assortment framework model in light of the general model of recommendation framework and the general model of versatile learning framework is shown in Figure 1.Figure 1
Model diagram of personalized acquisition system of learning resources.The model not only includes the basic modules and optional implementation innovations of the customized recommendation process for learning resources yet additionally incorporates the learning hypothesis that can be utilized as a help. It can give direction to the development of this point and even a customized recommendation procedure for learning resources for people in the future. Fluffy grouping is a strategy to order target objects by involving the similitude relationship in fluffy mathematics [6]. The center of the versatile recommendation model is reflected in the client fluffy bunching part; that is to say, the client customized model is laid out by working out the client’s advantage in teaching resources, and the grouping technology is used to cluster the users with similar preferences. Predict users’ preferences for unknown teaching resources according to the similarity of teaching resources in similar groups [7]. On this basis, complete the user-based collaborative filtering recommendation algorithm, rank their satisfaction according to groups, and generate the top-N teaching resource recommendation set [8]. The adaptive classification management model of teaching resources based on fuzzy clustering is as shown in Figure 2.Figure 2
Adaptive classification management model of teaching resources based on school enterprise cooperation.The purpose of adaptive recommendation is to provide personalized teaching resources for users with different retrieval intentions, and obtaining users’ retrieval intentions is a crucial prerequisite for the ultimate realization of this purpose [9]. In the conventional network resource system, the resource retrieval intention expressed by users is generally expressed by scoring data that can reflect their interest characteristics. For example, the recommendation system of various film and music resource websites adopts the user active scoring system. Through the classification of learning results and the proposal of a nine-stage teaching procedure, it has an important impact on teaching design [10]. In learning activities, teaching activities can be organized in the order of students’ learning activities. The specific teaching examples are designed as in Table 1.Table 1
Nine-stage ideological and political learning resource management procedure and learning activity design.

Simultaneously, the client interest offset of target resources cannot be gathered in time. Truth be told, clients’ web-based conduct frequently suggests their advantage in target teaching resources [11]. For instance, assuming the client peruses the brief teaching resource page in under one moment, it implies that the client is not happy with the ongoing teaching resources or has low interest. Assuming there are downloading, printing, gathering, or saving activities, it demonstrates that the client is happy with or keen on the ongoing teaching resources. The fundamental standard of fluffy grouping for clients of teaching resources is to bunch clients through client portrayal records or at least the level of clients’ advantage in the objective teaching resources [12]. The client’s advantage can be depicted by vector space model. Toward the start of grouping, a delegate client is chosen as the bunching focus of this sort of clients, and the bunching focus is progressively changed by the likeness between the ongoing client and the grouping place until the preset limit is met, and at long last, the fluffy grouping of the objective teaching resource clients is created. The estimation recipe of similarity is as follows:
(1)SAv,r′=γ∑k=1nμkw−λw¯∑ueUAu,i+A¯i−μk.Among them,μkw is the user μk interest preference value for the fuzzy cluster Au,i of teaching resources, and λw is the average interest preference value of users A¯i for all fuzzy clusters of teaching resources. User pnt,j representation of teaching resources is consistent with that of user nsi,nt. after the client’s fluffy grouping not set in stone, SAw clients in the bunch where the client to be suggested belongs and their nearest neighbors are selected according to the similarity, and the SAv¯ nearest neighbors’ interest in the objective teaching resources is utilized to foresee the objective teaching resources r of the client to be suggested. The computation recipe is as per the following:
(2)Sw,r=SAw¯+∑t=1knsi,nt⋅pnt,j∗SAv,r′−SAv¯∑v=1n1+μ.InterimAB addresses the closeness between client wi,d2 and its closest neighbor client wi,S2, κ represents the average interest of user σ, and E represents the interest of nearest neighbor user V in the target teaching resource R. According to this formula, the predicted values of all teaching resources RS in the teaching resource set R are calculated, and then, the top-N recommendation set is created by taking the principal n teaching resources from large to small according to the value of Sw,r. The main function of the Chinese text personalized recommendation module is to use the personalized recommendation algorithm to compare the text vector model of learning resources with the learner interest vector model and recommend the first eight learning resources with high similarity to the learner interest vector model to learners [13]. Because this paper chooses the vector space model to address the text resources and students’ inclinations, it is considered to utilize the cosine comparability recipe to compute the likeness between the text vector model and students’ advantage vector model. The customary cosine likeness computation equation is as per the following:
(3)Simd,S=κ−1Sw,r−1−Rσ∏AB+dE∑wi,d2∑wi,S2.The formula only matches the feature words of the text vector model with the keywords of the learner’s interest vector model to calculate the similarity between them and ignores the case that although the feature words in the text vector model do not appear in the learner’s interest vector model, the words whose semantic correlation is greater than a certain threshold may exist in the learner’s interest vector model [14]. This learning resource should also meet learners’ potential interests and should be recommended to learners. The customized recommendation procedure for learning resources in view of metaphysics is made out of student connection point and executive point of interaction. The student interface comprises of four modules: enlistment and login module, interest the board module, resource show module, and recommendation module [15]. The instructor manager interface comprises of three modules: learning resource the executive’s module, cosmology the board module, and framework the board module. The specific module diagram is as shown in Figure 3.Figure 3
Ideological and political teaching resource management function.Learning behavior is a sequence set of a series of abstract activities. In order to better evaluate members’ interest in resources and determine the weight values of different behaviors, the above data need to be quantified [3]. The commonly used quantization method is the binary function method. When the learning behavior has only two states d and tmaxv, it can be quickly quantified through the binary function method. For example, the download behavior has only two states: occurrence and nonoccurrence; that is, if the behavior occurs, set its score value to 1; otherwise, the score value is ti. However, this method also has some limitations. For example, different students may watch videos different times [16]. The binary function method ignores the different preferences of different members for the same resource in the scoring process, which reduces the accuracy of prediction scoring. To work on the proficiency of measurement and work on the precision of some learning behavior data prediction scores, this paper quantifies them in the following ways, as defined below:
(4)InterestTw=σ∑i=1dti−Simd,Sd∗tmaxv.From the perspective of the participants of the course learning platform, there are four types of main participants in the platform [17]. Among them, if students do not log on to the platform, they are tourists. Tourists can only browse resources, not comment on resources, nor participate in the discussion of the learning community and obtain resource recommendations: if students log on to the platform, they can enter their own learning home page, browse videos, and learn courses [18–21]. Participate in community discussions, obtain recommended resources, etc. Teachers are the managers of all resources. They upload and update resources to meet the needs of more learners: background management is mainly responsible for maintaining the platform. Their main business functions are as shown in Table 2.Table 2

In the learning community module, students can communicate with other members and obtain the recommended list of resources. However, these functions can only be used after students log in to the platform.


### 2.2. Adaptive Management Evaluation Algorithm of Ideological and Political Teaching Resources

At present, although the recommendation framework has been broadly utilized in many fields and numerous analysts and designers are contemplating and utilizing customized recommendation innovation, there is no unmistakable meaning of the recommendation framework. The primary undertaking of the recommendation framework is to associate clients and data resources to assist clients with finding data resources valuable to them. Simultaneously, it additionally permits data resources to be introduced to clients keen on them [3, 22–24]. The general model of the recommendation framework is displayed in the figure. It is made out of three modules: client model, recommendation object model, and recommendation calculation. The recommendation calculation module contrasts the client model and the article model. Sort and suggest the items that clients are probably going to be keen on the clients. From the above presentation, it very well may be seen that the meaning of the recommendation framework and the general model of the recommendation framework are basically situated to the business field, and there is not a lot of thought on the use of the recommendation framework in the field of education. Nonetheless, it actually has a specific reference for an incentive. From the meaning of a broadly utilized recommendation framework, it very well may be expanded that a recommendation framework in the field of education ought to be a framework that utilizes web-based learning sites to give students learning resource data and ideas to assist students with concluding what content to realize. The primary assignment is to associate students and learning resources to assist students with tracking down important learning resources for them and likewise permit learning resources to be introduced to students keen on them. The general model of recommendation framework can likewise give a reference to the development of a customized recommendation framework model of learning resources as shown in Figure 4.Figure 4
General model of the recommendation system.In order to make better resource recommendation for nonmajors and avoid the defects of user-based and project-based collaborative filtering algorithm in practical applicationRi,k, this paper proposes the following algorithm, which combines user-based Ri¯ and project-based collaborative filtering algorithm Ru¯ and adopts hybrid recommendation and Pearson similarity algorithm Ru,k, and the similarity sim (U,I) between target user u and user I is

(6)Pu,j=Yq+∑n∈NαSimu,iλ−σn∑n∈NuSimu,i.Combined with the research object of this paper, model fusion refers to using a certain preference fusion strategy to obtain the score of the group on the learning resources based on the score data of the learning members of the learning local area on the learning resources and then utilizing the customary collaborative filtering recommendation method to predict the score, so as to realize the group-oriented learning resource recommendation. Recommendation fusion is to obtain the prediction score of each member of the learning community on learning resources through recommendation technology, then fuse the prediction score of members based on a certain fusion strategy, obtain the prediction score of the group, establish the preference model of the group, and then produce the recommendation results. This study adopts the recommendation fusion strategy to obtain the group recommendation list by fusing the recommendation list of members, so as to realize the group-oriented resource recommendation. The intelligent recommendation fusion method of teaching resources is as shown in Figure5.Figure 5
Intelligent recommendation fusion method of teaching resources.Through the hierarchical relationship of the five subcategories of school enterprise cooperation, it can be concluded that more complex skill learning is based on simple skill learning. Therefore, for the identification and concept learning in the primary stage, the content organization of the learning platform should focus on well-structured domain knowledge, and the content presentation should focus on words and pictures and increase the interaction between the platform and learners. For the advanced stage of learning using rules, the learning platform should focus on non-well-structured domain knowledge, such as problem solving, and increase the diversity of learning evaluation methods in learning navigation, which is helpful for the inside and out advancement of understudies. In order to respect the learning characteristics of learners, according to the different learning stages of school enterprise cooperation, the learning platform provides learners with adaptive learning services and customize personalized adaptive learning navigation for learners which is shown Table3.Table 3

### 2.3. Implementation of Adaptive Recommendation of Ideological and Political Teaching Resources

In rule-based recommendation, the system administrator formulates rules according to the static characteristics and dynamic attributes of users. Rules can be customized by users or discovered by data mining technology based on association rules. In the system of using rules for recommendation, the quality of recommendation depends on the quality and quantity of rules. A rule is essentially an if-then statement, which determines how to provide different services in different situations. The rule-based recommendation system generally includes three parts: keyword layer, description layer, and user interface layer as shown in Figure6.Figure 6
Characteristic information recommendation method of ideological and political teaching resources.The bottom layer in the figure provides the required keywords for the upper layer description and defines the dependencies between keywords. In this layer, you can also define the personalization rules of static attributes. The description layer above the keyword layer defines user and resource descriptions. This layer is specific to users and resources, so its personalization rules are dynamic. The user interface layer at the top layer recommends the resources meeting the rules to users according to the personalized rules defined in the following two layers. By comprehensively considering the learner’s characteristic information and matching the resource information described in the resource database (resource form, difficulty coefficient, content correlation, etc.), recommend the learning resources most suitable for learners’ learning, and in the personalized page design database, recommend the most suitable learning interface navigation. The recommendation mode of learning resources in ideological and political teaching is as shown in Figure7.Figure 7
Recommendation model of learning resources for ideological and political teaching.Database often assumes a vital part in the stage. The underlying model of data set will influence the productivity of use stage and the acknowledgment of learning impact. Client model is utilized to portray, store, and deal with clients’ inclinations and requirements. Since customized recommendation depends on the PC stage, in light of the fact that the client model is certainly not an overall portrayal of client interests, however, a calculation is situated, a formal depiction with explicit information structure. As the primary stage, client demonstrating is essentially to acquire information connected with keeping up with client interests, client needs, or propensities. The consequence of client displaying is to deliver a client model that represents the user’s unique background knowledge or interests and needs. In order to respect the learning characteristics of learners, according to the different learning stages of school enterprise cooperation, learning level provides learners with adaptive learning services and customized personalized adaptive learning navigation for learners as shown in Table4.Table 4
Personalized services based on learning objectives.

Through the statistics of behavior attributes and data, we can not only better grasp the information characteristics of learners but also help to select learning resources more suitable for learners’ needs. The specific network behavior attributes are as shown in Table5. Finally, the behavior attributes and data are stored in the learner behavior feature database to prepare for the recommendation of later learning resources.Table 5
Recommended behavior attributes of main teaching information.

In the recommendation output stage, these matching projects will be presented to users in the form of predicted value, top-N recommendation or other forms. Group teaching resources as per disciplines. For the objective clients, the resources they focus on are separated into two classifications: proficient resources and nonproficient resources. This division is straightforward and clear and makes the recommendation more designated and more proficient. These two sorts of resources can be isolated into the most recent resources, store resources, and resources important to clients. Explicit grouping structure graph. The ordered administration of ideological and political teaching resources is as shown in Figure 8.Figure 8
Classified management of ideological and political teaching resources.It tends to be seen that client displaying is the premise and center of customized recommendation and client model is the principal information wellspring of customized recommendation framework. Whether the client model can catch the genuine inclinations of the client’s furthest degree decides the progress of recommendation, and its quality is straightforwardly connected with the nature of customized administration. Thusly, just a precise understanding of clients’ inclinations and requirements can furnish clients with good recommendations. The demonstrating system of customized recommendation framework incorporates four errands: information assortment, model portrayal, model learning, and model update. The relationship is as shown in Figure9.Figure 9
Modeling process of personalized recommendation system.There are numerous sorts of teaching resources; however, the essential disciplines they have a place with are extremely clear. We can be aware from the “proficient code” quality in the teaching resource model to understand the sensible administration and characterization of various kinds of teaching resources. In light of the above research content, the versatile management and recommendation of teaching resources can better ensure the recommendation effect.


## 2.1. Collection and Management of Online Ideological and Political Teaching Resources

During the time spent building recommendation strategies, assuming there is model direction, it will come by two times the outcome with around 50% of the work. Be that as it may, there is no framework model for customized recommendation of learning resources in the field of education [4]. The customized recommendation procedure for learning resources can be viewed as the particular utilization of the recommendation framework in the field of education and a versatile learning framework. Hence, the general model of the recommendation framework and the general model of the versatile learning framework can give a reference. In any case, the general model of recommendation framework is basically focused on the business field and cannot be completely pertinent to the customized recommendation of learning resources [5]. The general model of versatile learning framework covers a wide reach, is not explicitly for the recommendation framework, and cannot completely address the issues. Subsequently, after top to bottom investigation of the important speculations and innovations of customized education and recommendation framework, this paper proposes a customized learning resource assortment framework model in light of the general model of recommendation framework and the general model of versatile learning framework is shown in Figure 1.Figure 1
Model diagram of personalized acquisition system of learning resources.The model not only includes the basic modules and optional implementation innovations of the customized recommendation process for learning resources yet additionally incorporates the learning hypothesis that can be utilized as a help. It can give direction to the development of this point and even a customized recommendation procedure for learning resources for people in the future. Fluffy grouping is a strategy to order target objects by involving the similitude relationship in fluffy mathematics [6]. The center of the versatile recommendation model is reflected in the client fluffy bunching part; that is to say, the client customized model is laid out by working out the client’s advantage in teaching resources, and the grouping technology is used to cluster the users with similar preferences. Predict users’ preferences for unknown teaching resources according to the similarity of teaching resources in similar groups [7]. On this basis, complete the user-based collaborative filtering recommendation algorithm, rank their satisfaction according to groups, and generate the top-N teaching resource recommendation set [8]. The adaptive classification management model of teaching resources based on fuzzy clustering is as shown in Figure 2.Figure 2
Adaptive classification management model of teaching resources based on school enterprise cooperation.The purpose of adaptive recommendation is to provide personalized teaching resources for users with different retrieval intentions, and obtaining users’ retrieval intentions is a crucial prerequisite for the ultimate realization of this purpose [9]. In the conventional network resource system, the resource retrieval intention expressed by users is generally expressed by scoring data that can reflect their interest characteristics. For example, the recommendation system of various film and music resource websites adopts the user active scoring system. Through the classification of learning results and the proposal of a nine-stage teaching procedure, it has an important impact on teaching design [10]. In learning activities, teaching activities can be organized in the order of students’ learning activities. The specific teaching examples are designed as in Table 1.Table 1

Simultaneously, the client interest offset of target resources cannot be gathered in time. Truth be told, clients’ web-based conduct frequently suggests their advantage in target teaching resources [11]. For instance, assuming the client peruses the brief teaching resource page in under one moment, it implies that the client is not happy with the ongoing teaching resources or has low interest. Assuming there are downloading, printing, gathering, or saving activities, it demonstrates that the client is happy with or keen on the ongoing teaching resources. The fundamental standard of fluffy grouping for clients of teaching resources is to bunch clients through client portrayal records or at least the level of clients’ advantage in the objective teaching resources [12]. The client’s advantage can be depicted by vector space model. Toward the start of grouping, a delegate client is chosen as the bunching focus of this sort of clients, and the bunching focus is progressively changed by the likeness between the ongoing client and the grouping place until the preset limit is met, and at long last, the fluffy grouping of the objective teaching resource clients is created. The estimation recipe of similarity is as follows:
(1)SAv,r′=γ∑k=1nμkw−λw¯∑ueUAu,i+A¯i−μk.Among them,μkw is the user μk interest preference value for the fuzzy cluster Au,i of teaching resources, and λw is the average interest preference value of users A¯i for all fuzzy clusters of teaching resources. User pnt,j representation of teaching resources is consistent with that of user nsi,nt. after the client’s fluffy grouping not set in stone, SAw clients in the bunch where the client to be suggested belongs and their nearest neighbors are selected according to the similarity, and the SAv¯ nearest neighbors’ interest in the objective teaching resources is utilized to foresee the objective teaching resources r of the client to be suggested. The computation recipe is as per the following:
(2)Sw,r=SAw¯+∑t=1knsi,nt⋅pnt,j∗SAv,r′−SAv¯∑v=1n1+μ.InterimAB addresses the closeness between client wi,d2 and its closest neighbor client wi,S2, κ represents the average interest of user σ, and E represents the interest of nearest neighbor user V in the target teaching resource R. According to this formula, the predicted values of all teaching resources RS in the teaching resource set R are calculated, and then, the top-N recommendation set is created by taking the principal n teaching resources from large to small according to the value of Sw,r. The main function of the Chinese text personalized recommendation module is to use the personalized recommendation algorithm to compare the text vector model of learning resources with the learner interest vector model and recommend the first eight learning resources with high similarity to the learner interest vector model to learners [13]. Because this paper chooses the vector space model to address the text resources and students’ inclinations, it is considered to utilize the cosine comparability recipe to compute the likeness between the text vector model and students’ advantage vector model. The customary cosine likeness computation equation is as per the following:
(3)Simd,S=κ−1Sw,r−1−Rσ∏AB+dE∑wi,d2∑wi,S2.The formula only matches the feature words of the text vector model with the keywords of the learner’s interest vector model to calculate the similarity between them and ignores the case that although the feature words in the text vector model do not appear in the learner’s interest vector model, the words whose semantic correlation is greater than a certain threshold may exist in the learner’s interest vector model [14]. This learning resource should also meet learners’ potential interests and should be recommended to learners. The customized recommendation procedure for learning resources in view of metaphysics is made out of student connection point and executive point of interaction. The student interface comprises of four modules: enlistment and login module, interest the board module, resource show module, and recommendation module [15]. The instructor manager interface comprises of three modules: learning resource the executive’s module, cosmology the board module, and framework the board module. The specific module diagram is as shown in Figure 3.Figure 3
Ideological and political teaching resource management function.Learning behavior is a sequence set of a series of abstract activities. In order to better evaluate members’ interest in resources and determine the weight values of different behaviors, the above data need to be quantified [3]. The commonly used quantization method is the binary function method. When the learning behavior has only two states d and tmaxv, it can be quickly quantified through the binary function method.

Recommendation fusion is to obtain the prediction score of each member of the learning community on learning resources through recommendation technology, then fuse the prediction score of members based on a certain fusion strategy, obtain the prediction score of the group, establish the preference model of the group, and then produce the recommendation results. This study adopts the recommendation fusion strategy to obtain the group recommendation list by fusing the recommendation list of members, so as to realize the group-oriented resource recommendation. The intelligent recommendation fusion method of teaching resources is as shown in Figure5.Figure 5
Intelligent recommendation fusion method of teaching resources.Through the hierarchical relationship of the five subcategories of school enterprise cooperation, it can be concluded that more complex skill learning is based on simple skill learning. Therefore, for the identification and concept learning in the primary stage, the content organization of the learning platform should focus on well-structured domain knowledge, and the content presentation should focus on words and pictures and increase the interaction between the platform and learners. For the advanced stage of learning using rules, the learning platform should focus on non-well-structured domain knowledge, such as problem solving, and increase the diversity of learning evaluation methods in learning navigation, which is helpful for the inside and out advancement of understudies. In order to respect the learning characteristics of learners, according to the different learning stages of school enterprise cooperation, the learning platform provides learners with adaptive learning services and customize personalized adaptive learning navigation for learners which is shown Table3.Table 3

## 2.3. Implementation of Adaptive Recommendation of Ideological and Political Teaching Resources

In rule-based recommendation, the system administrator formulates rules according to the static characteristics and dynamic attributes of users. Rules can be customized by users or discovered by data mining technology based on association rules. In the system of using rules for recommendation, the quality of recommendation depends on the quality and quantity of rules. A rule is essentially an if-then statement, which determines how to provide different services in different situations. The rule-based recommendation system generally includes three parts: keyword layer, description layer, and user interface layer as shown in Figure6.Figure 6
Characteristic information recommendation method of ideological and political teaching resources.The bottom layer in the figure provides the required keywords for the upper layer description and defines the dependencies between keywords. In this layer, you can also define the personalization rules of static attributes. The description layer above the keyword layer defines user and resource descriptions. This layer is specific to users and resources, so its personalization rules are dynamic. The user interface layer at the top layer recommends the resources meeting the rules to users according to the personalized rules defined in the following two layers. By comprehensively considering the learner’s characteristic information and matching the resource information described in the resource database (resource form, difficulty coefficient, content correlation, etc.), recommend the learning resources most suitable for learners’ learning, and in the personalized page design database, recommend the most suitable learning interface navigation. The recommendation mode of learning resources in ideological and political teaching is as shown in Figure7.Figure 7
Recommendation model of learning resources for ideological and political teaching.Database often assumes a vital part in the stage. The underlying model of data set will influence the productivity of use stage and the acknowledgment of learning impact. Client model is utilized to portray, store, and deal with clients’ inclinations and requirements. Since customized recommendation depends on the PC stage, in light of the fact that the client model is certainly not an overall portrayal of client interests, however, a calculation is situated, a formal depiction with explicit information structure. As the primary stage, client demonstrating is essentially to acquire information connected with keeping up with client interests, client needs, or propensities. The consequence of client displaying is to deliver a client model that represents the user’s unique background knowledge or interests and needs. In order to respect the learning characteristics of learners, according to the different learning stages of school enterprise cooperation, learning level provides learners with adaptive learning services and customized personalized adaptive learning navigation for learners as shown in Table4.Table 4

Through the statistics of behavior attributes and data, we can not only better grasp the information characteristics of learners but also help to select learning resources more suitable for learners’ needs. The specific network behavior attributes are as shown in Table5. Finally, the behavior attributes and data are stored in the learner behavior feature database to prepare for the recommendation of later learning resources.Table 5

In the recommendation output stage, these matching projects will be presented to users in the form of predicted value, top-N recommendation or other forms. Group teaching resources as per disciplines. For the objective clients, the resources they focus on are separated into two classifications: proficient resources and nonproficient resources. This division is straightforward and clear and makes the recommendation more designated and more proficient. These two sorts of resources can be isolated into the most recent resources, store resources, and resources important to clients. Explicit grouping structure graph. The ordered administration of ideological and political teaching resources is as shown in Figure 8.Figure 8
Classified management of ideological and political teaching resources.It tends to be seen that client displaying is the premise and center of customized recommendation and client model is the principal information wellspring of customized recommendation framework. Whether the client model can catch the genuine inclinations of the client’s furthest degree decides the progress of recommendation, and its quality is straightforwardly connected with the nature of customized administration. Thusly, just a precise understanding of clients’ inclinations and requirements can furnish clients with good recommendations. The demonstrating system of customized recommendation framework incorporates four errands: information assortment, model portrayal, model learning, and model update. The relationship is as shown in Figure9.Figure 9
Modeling process of personalized recommendation system.There are numerous sorts of teaching resources; however, the essential disciplines they have a place with are extremely clear. We can be aware from the “proficient code” quality in the teaching resource model to understand the sensible administration and characterization of various kinds of teaching resources. In light of the above research content, the versatile management and recommendation of teaching resources can better ensure the recommendation effect.


## 3. Analysis of Experimental Results

The disconnected information is utilized for tests. The information is isolated into a preparing set and test set. The learning inclination model is laid out on the preparation set by the suggested strategy, and then, at that point, assessed in light of the expectation consequences of the test set. This paper utilizes the recommendation methodology in view of element disintegration machine to get the forecast score of learning local area individuals. To check the viability of its strategy, this paper looks at the conventional recommendation technique in view of client cooperative separating from the assessment file of recommendation exactness, which alludes to the occurrence between the anticipated score and the genuine score on the test set. The anticipated score is determined by displaying the preparation informational collection. Precision is by and large determined through root mean square blunder and mean mistake MAE. The estimation strategy for MAE is basic and straightforward: RMSE will increase the penalty of large error value in prediction score, and the requirements for evaluation are more strict. It is defined that in the test set, the actual score of learning community memberu on resource n is Rui, rui is the predicted score of member u on resource I trained according to the recommended method, T is the test set, and the calculation of root mean square error (RMSE) is as follows:
(7)RMSE=∑U,i∈TRui−rui2T.The mean error MAE measures the exactness of recommendation by ascertaining the distinction between the score of the test set and the anticipated score. The mean mistake MAE is characterized as(8)MAE=∑U,i∈TRui−ruiT−n.To confirm the viability of learning local area situated recommendation, this paper plans to analyze the gathering recommendation technique in view of mean combination system. Nonetheless, the learning local area arranged recommendation technique could not utilize the root at any point mean square mistake (RMSE) and normal blunder MAE to work out the exactness, on the grounds that contrasted and the individual situated recommendation precision assessment strategy; the genuine score of the gathering on resources does not exist unbiasedly; however, it should be gotten by combination through examination. In this manner, the above assessment pointers are not reasonable for the assessment of the precision of gathering recommendation. To check the precision of gathering recommendation, this paper ascertains the exactness of gathering recommendation as indicated by the assessment record of gathering recommendation. The particular computation technique is as per the following:(9)RMSEg=∑i=0nRui−rgi2n.The RMSE determined by the recommendation technique proposed in this paper is contrasted and the gathering recommendation strategy in view of mean procedure to confirm the exactness of recommendation. To concentrate on the general action of the college understudy discussion, the chosen agent college data is ordered, arranged, and considered which is shown in Table6. A histogram is attracted by the all-out number of posts, the typical number of posts each day, and the typical number of posts per client.Table 6
Collection of ideological and political online teaching information training sets in different universities.
Total posts (PCs.)Statistical time (days)Average daily posts (PCs.)Posting user (person)Average number of users (PCs.)A university1695862586519586.32136525133.25B university598562798758.657685207.82C university36598568654653.5226525141.32D university7655891285.2178329.98When the proportion of training sets is different, the recommendation results of the recommendation algorithm are different. In this group of experiments, eight different training set ratios are selected, the user’s score on a certain item is hidden, and the number of nearest neighbors is 30. The experimental results are as shown in Figure10.Figure 10
Influence of different proportions of teaching resource training set on recommendation.In order to verify the recommendation effect for learning community, the scale of learning communitys=2,5,18,31,50,62 selected in this paper is compared with the accuracy of group recommendation based on mean fusion strategy. The specific experimental results are as shown in Figure 10.The comparative recommendation method in the experiment is the recommendation based on the mean fusion strategy, which means that when the recommendation list of members is fused to obtain the group recommendation list, the weight values of all members are defined as 1 without considering the different weights of different members in the learning community. It tends to be seen from Figure11that the RMSE’s worth of the recommendation calculation proposed in this paper is undeniably not exactly theRMSEg of the recommendation calculation in view of the mean combination procedure. The more modest the RMSE esteem, the more modest the mistake, and that implies that the aftereffect of resource recommendation for the learning local area in this paper is more precise. During the investigation, the quantity of closest neighbors of the objective clients of teaching resources expanded from 20 to 50, and the step size was 5. The precision of the customary cooperative separating recommendation strategy and the technique in view of this paper were calculated and compared, respectively. The experimental results are as shown in Figure 12.Figure 11
Comparison of RMSE values recommended by average fusion of teaching resources.Figure 12
Comparison test results of information recommendation accuracy.The exploratory outcomes show that the proposed strategy has more modest MAE esteem than the conventional cooperative separating recommendation technique, which shows that the precision and nature of teaching resource recommendation expectation are better. This is on the grounds that the conventional cooperative separating recommendation calculation looks the closest neighbor of the objective client in all client spaces, while the recommendation calculation in view of fluffy grouping looks through in the bunched client space, so the exactness of recommendation is enormously gotten to the next level. Besides, with the increment of the quantity of closest neighbors of target clients, the more prominent the distinction between their MAE, showing that the recommendation forecast precision and quality advantages based on this method are more obvious.


## 4. Conclusion

With the acceleration of educational informatization, intelligent adaptive recommendation has become an important part of the construction and application of teaching resources. Aiming at the problem that the accuracy and personalization of the feedback results of conventional resource retrieval and traditional recommendation methods are low due to the increment of the quantity of teaching resources, a cooperative separating recommendation strategy in view of fluffy grouping is proposed. The trial results show that the recommendation quality and exactness have been extraordinarily gotten to the next level. Moreover, this paper likewise presents canny word division innovation and portable specialist innovation to upgrade the mental prowess of various clients in the recommendation cycle and work on the fulfillment of resource clients. Notwithstanding, explorations likewise show that with the increment of the quantity of closest neighbors of the objective client, the time effectiveness of resource recommendation will be decreased somewhat, albeit this interaction can be determined disconnected. Thusly, the future work will make further exploration on working on the nature of resource recommendation and successfully working on the constant execution of the calculation.
