Introduction
In recent years, the Ministry of Education has clearly proposed the use of the network environment to provide college students with high-quality study, life and employment services. Combining with my country's traditional ideological education model, create a network communication platform based on artificial intelligence to enable multiple interactions between teachers and students, highlighting the deep integration between teachers and students [1][2]. Facing the requirements of online party building work under the new situation, how to strengthen the communication and interaction between teachers and students, correctly guide college students to use their strengths and avoid their shortcomings, and provide them with a safe, stable and pure network communication platform. New issues facing the current ideological and political education in colleges and universities. Teachers should use the advantages and characteristics of the network platform to communicate and interact with students to further promote the organization and informationization of grassroots party building [3][4]. The application of the network communication platform based on artificial intelligence technology can enable in-depth communication between schools, teachers, students and society and other parties, so that students can understand the society and prepare and plan for employment.

Natural language understanding
Human beings are intelligent creatures with many intelligent behaviors, the most important of which is language. The technology of obtaining human thoughts through computer technology is called natural language processing, which can imitate human language ability, including languages of different countries and dialects of different regions. If a machine system can interpret natural language information, then this machine system can replace humans to do some tasks that require language skills. Nowadays, natural language understanding technology has been widely used in the field of language teaching and has great potential value. The emergence of natural language understanding technology provides a brand-new interface for machine intelligence systems and brings a huge revolution to the field of human-machine intelligence. Natural language understanding technology is mainly used in the fields of speech recognition and text recognition. In the teaching system, the main function of natural language understanding technology is to translate and interpret the language. For example, in the process of English teaching, voice communication is carried out through the human-machine interface of intelligent robots, which makes the interaction between humans and machines more convenient, creating good conditions for human-machine voice communication.

Machine learning
Machine learning is an important research direction of artificial intelligence technology. Machine learning mainly analyzes existing data to draw corresponding information conclusions, reconstruct the information content of the conclusions, and finally store all the information in the system. If a system does not have the ability to learn, the system is not intelligent. Machine learning has a huge impact on people, and the education industry is no exception. Moreover, an important function of machine learning is to obtain the information contained in the data, which can also be called data mining. For example, machine learning can be used to analyze the revenue data of a certain company over the past year, obtain corresponding information, effectively analyze the reasons for the formation of the company's profit and loss, and give corresponding development strategies. To put it simply, machine learning is to learn from the problems that have occurred before in the work, obtain a lot of information, and complete the work quickly and effectively from all the information.

Smart search
The 21st century is an information age, and all areas of society are flooded with a lot of information, especially on network platforms. The large amount of information on the Internet makes it difficult for people to focus their attention, making it difficult to find the information they want. Therefore, people especially hope that there is a way to quickly find accurate information on the Internet to help them complete their query work. In response to this problem, intelligent search in the field of artificial intelligence has been developed. Smart search is a brand-new search technology that can accurately find the content you need from a large number of information systems very quickly. The most common type of artificial intelligence is intelligent search, which is also an indispensable technology in intelligent query. In other words, intelligent search is a method of logical reasoning in order to complete the search task. The advantage of intelligent search is that it can intelligently judge the corresponding information based on previous traces, delete incorrect content, and quickly present the answer to people.

Long-term management mechanism for teachers to contact students
The network communication platform based on artificial intelligence technology is used for teachers to contact students, and a long-term management mechanism should be formed from the following four aspects: (1) Organizational guarantee. Strengthening teacher awareness and establishing a connection mechanism with students can further promote the ideological education of college students and enable teachers to actively and consciously contact students.
(2) Quality assurance. Teachers with high professional quality and professional ability are the key factors. Gradually establish a high-quality teacher database on a network platform, so as to better ensure the development of teacher-student interaction and avoid it becoming a mere formality.
(3) Feedback mechanism. After the teacher assigns tasks and determines the contact person, it is necessary to rely on the network platform to provide guidance and answer questions for students, so that they can achieve a qualitative leap in life, study, and thinking.
(4) Reward and punishment mechanism. Teachers are regularly trained, and communication should be strengthened between teachers and teachers, so that teachers have a better working ability, working methods and working art to carry out students' ideological education. With students as the core, build a communication and interactive network platform to form a long-term mechanism for teacher-student contact. Make the way and channel of teacher-student contact and communication more smooth, better serve students, and help students deal with difficulties in life and study more effectively. The formulas

The main form of interaction between teachers and students
Based on the exchange and interactive network platform, teachers can carry out a series of activities such as topic seminars, online communication, and professional Q&A. Through the exchange and interactive network platform, it is convenient for teachers to get a more timely and comprehensive understanding of students' learning and mental performance. The heart-to-heart talk activities through the exchange and interactive network platform also overcome the limitations of geographic location. Teachers should guide students to complete social practice reports, form a highlight area on the exchange and interactive network platform, and form a good atmosphere for students to actively participate in social practice to improve their abilities and accomplishments. Teachers should base themselves on entrepreneurship and employment, and take the initiative to help students prepare and plan. Relying on the exchange and interactive network platform to plan job search and employment cases, release employment guidance information, and interpret entrepreneurship and employment policies. Improve students' job hunting ability and stimulate students' initiative and initiative in self-employment. To enable students to have an in-depth understanding of their future careers, focus on their current studies and future careers, prepare for them, and strive to improve themselves. In the process of contacting students, teachers should make video materials of successful experiences, effective practices, typical characters, and advanced deeds in time, and upload them to the exchange and interactive network platform. As a modern media, the internet has a huge influence on college students. However, various websites are now complex, and a variety of novel social thoughts are always surrounding contemporary college students, which profoundly affects the political progress and growth of college students. Teachers should make full use of the exchange and interactive network platform to publicize the political advantages of the party, and build the school's red cultural front with the teacher-student exchange and interactive network platform, so that teachers and students can unite closely to build a civilized, harmonious and smart campus.

Student user
The network communication platform based on artificial intelligence technology involves school teachers, students and administrators, and the number of users is very large. To be able to meet online communication, the platform needs to have a good guarantee in terms of security and response speed, so the platform architecture uses AJAX technology. AJAX technology has outstanding advantages that are different from traditional applications. All interactive pages do not need to be refreshed, so that data acquisition does not require reconnection to the server. This not only reduces the access pressure of the server, but also improves the page refresh speed, making the interaction between users smoother. Since there are many interactions and frequent data reading in this system, the advantages of AJAX in asynchronous interaction and dynamic update can be fully utilized. AJAX reads data as needed, avoiding data redundancy and waste, and reducing the load on the server. The interaction between the user and the server does not require operations such as refreshing the page, which greatly improves the user experience. In the layout design of the page, the master page technology is adopted. Using the master page can create a consistent style and layout for the website. It only needs to be compiled once and it can be applied to all pages. It can be used to integrate the common parts of each page into the master page to achieve a consistent page layout. Learn about relevant policies and regulations through wonderful reading, grasp the dynamics of the school, and solve the daily problems that students pay close attention to. The comment column collects student feedback, and provides students with a fast  Figure 1, we can know that the system function is tested 15 times, and the test results show that: 12 times the function is correct, accounting for 80%. There was 1 function error, accounting for 6.7%. There were 2 non-responses, accounting for 13.3%. In-depth analysis of the functional error and non-response situation revealed that the functional error was caused by the incorrect function path collocation, and the non-response was caused by the network stuck. Therefore, excluding reasons other than the system, the function of the system is very accurate.  Figure 2. Performance test results According to Table 2 and Figure 2, as the number of connections increases, the memory footprint of the server also increases. When the server maintains 1000 connections, the memory footprint does not exceed 450MB. Since servers generally have a memory capacity of tens of GB to tens of GB, the performance of this system is sufficient to support nearly 10,000 users at the same time.
