2. Project introduction
Although the application of information technology has brought a lot of benefits, it also brought a big explosion of information and data. In the era of information scarcity, people expect to obtain more information and data in order to understand the world, but in the era of data explosion, people are often at a loss as to how to filter out the data that is useless to them and obtain effective data. Information. The research of this topic is based on the user preference to recommend the movie recommendation system, which mainly judges the user's preference according to the set relevant rules based on the user's operation behavior records on the platform, and uses the collaborative filtering algorithm to give the user Corresponding data recommendations. At the same time, when the user has no operation data record, that is, when the commonly used data is silent, it also recommends some movie data to the user according to the corresponding rules, in order to find some useful data for the user.
This system is mainly based on the Java development technology platform to achieve system development, using the SSM framework to complete the background service interface development and business logic processing of the movie recommendation system, using JSP pages to complete the data display, using AJAX and JQUERY to realize human-computer interaction asynchronous data request. The specific data recommendation mainly uses the data model of the collaborative filtering algorithm for data recommendation. The overall function of the system is complete, the interface is beautiful and elegant, and the human-computer interaction effect is good.
According to market research and user interviews, and analysis, it is known that there are two types of users in the movie recommendation system designed and implemented this time, one is front-end users, and the other is administrator users. These two types of users have different roles and operational function permissions, which are shown below in the form of a use case diagram.
The use case diagram of the front-end user is shown in Figure 1 below.
Figure 1 Front-end user use case diagram
Front-end user use case description: After the front-end user registers and logs in, they can mainly browse news information online, browse movie information by category, movie review information, movie strategy information released by users, view recommended movie information, make online feedback messages, book movie tickets, etc. , and at the same time, you can publish movie guides, view personal collection information, reservation information, etc. in the personal center.
The operation use case diagram of the administrator user is shown in Figure 2 below:
Figure 2 Administrator user use case diagram
Administrator user use case diagram description: The administrator logs in to the movie recommendation system, and his main responsibility is to manage the basic information of the platform, including front-end registered user information management, carousel map management, information management, movie management, genre management, movie description Review management, complaint management, reservation order management, strategy management, etc.
After a full demand analysis and architecture design of the entire movie recommendation system, the functional goals to be achieved by the movie recommendation system developed and designed are finally determined. The following shows the front-end user functional architecture and background management of the movie recommendation system. Functional Architecture Diagram. The functions of front-end users are shown in Figure 3 below.
Figure 3 Front-end user function structure diagram
Functional module introduction for front-end users:
(1) Registration and login function module design
Front-end users need to register as an online member when performing related operations. After filling in personal account information and personal information, they can log in after successful registration.
(2) Design of personal information management functional modules
After the user logs in to the system, he can enter the system management to modify the password, enter the old password, new password and confirm the password. If the new password is consistent with the confirmed password, the modification is successful, and if they are inconsistent, the modification fails.
(3) Information browsing function module
Front-end users can browse movie information, related movie commentary information, movie strategy information, industry information, etc. on the movie platform, view details of various types of information, and comment online. For favorite movies or movie reviews, you can Make favorites.
(4) Online reservation function module
After the front-end user logs in, enter the details page of the movie introduction, click the reservation button to book movies online, and manage the movies they have reserved in the personal center. After the background administrator approves, the reservation is considered successful.
(5) Movie strategy module
Users can post online, write their feelings about the movies they watch, or the strategy information of a certain movie, and manage their own posts online.
(6) Personalized recommendation module
The movie management platform system will perform relevant calculations based on the user's browsing records, and use collaborative filtering algorithms to recommend corresponding information to different users. The current data model is mainly based on the characteristics of the movies that users browse, matching relevant movies Information, recommended and displayed in the recommended module on the homepage.
(7) Full-text search module
In the movie management platform system, front-end users can search according to relevant keywords, and will match the full text of movie information, movie commentary information, etc., perform fuzzy matching according to the title description, and display the found information.
(8) Complaints and Suggestions
In addition to providing users with interactive functions such as online comments and favorites, it also provides a complaint and suggestion module, so that users can feedback relevant opinions in a timely manner, and the background administrator will handle them.
Functional module introduction for back-end users:
(1) Personal information management: The administrator can perform corresponding management operations on personal information by logging in to the background.
(2) User management: The administrator can perform corresponding management operations on the user information registered at the front end.
(3) Carousel map management: Carry out corresponding management operations on the carousel map information on the front-end home page, and replace the carousel map according to needs.
(4) Industry information management: mainly manage and publish relevant dynamic news information of the film industry.
(5) Movie management: It mainly manages released movie information, introduces movie prices, features, etc. in detail, and specifies the location coordinates of the movie theater map in the background, which allows front-end users to directly locate the location of the movie theater through Baidu Maps.
(6) Movie commentary management: It mainly manages related movie commentary information near the movie, and completes the operation of adding, deleting, modifying and checking movie commentary information.
(7) Order management: It mainly manages the order information of the front-end users. After the front-end members book a movie, it needs to be reviewed by the administrator in the background, and it can be used only after it takes effect.
(8) Raider management: mainly manages front-end movie member user releases and movie guide information.
(9) Complaints and Suggestions: Perform relevant management operations on complaints and suggestions issued by front-end users.

V. Project Summary
This topic mainly implements a movie information recommendation system based on user preferences. According to relevant analysis, this system mainly realizes the related operation functions of the two roles of front-end users and background management users, and specifically realizes online browsing, collection, commenting and reservation of movie information. function, and complete the data recommendation function of movie information according to the user's operation records. It mainly consists of the following chapters.
The first part mainly expounds the basic background and significance of developing this recommendation system through the introduction, and then describes the different research situations of the recommendation system at home and abroad and the related introduction and current status of the collaborative filtering algorithm application.
The second part introduces the SSM framework used in this system in detail, as well as the overall architecture model of the system and the type of database used.
The third part mainly analyzes the requirements of the system from various aspects and comprehensively, and demonstrates the feasibility of the system technology and operation, as well as the function points and non-functional requirements required by the system.
The fourth part mainly designs the overall architecture, functional architecture and business logic of the system based on the requirements of the system, and details the design of each small module, and also explains the database design and implementation of the system.
The fifth part mainly implements each functional module of the system and demonstrates the front-end page based on the system design in the previous part.
The sixth part of the test is to build a test environment and write test cases to complete the functional test of the system by clarifying the purpose and method of the test.
