Accurate and timely information can help companies make better business decisions and improve their competitiveness. Enterprises can understand important information such as market demand, competitor dynamics, product research and development directions, etc. through information collection, analysis and utilization, so as to better plan enterprise development strategies.
In today's highly competitive business environment, effective information management is also the key to success. A good information management system can help enterprises better integrate and utilize information resources and improve operational efficiency and effectiveness. For example, by establishing customer relationship management systems and supply chain management systems, companies can better manage customers and suppliers, improve customer satisfaction and supply chain stability.
The rapid development of information technology also provides enterprises with more opportunities. For example, the application of emerging technologies such as cloud computing and artificial intelligence can help enterprises better manage and analyze large amounts of data and provide more support and basis for enterprise decision-making. Therefore, enterprises need to pay more attention to information management and technological innovation to continuously improve their competitiveness and profitability [4].
The emergence of the recommendation system just meets all the above conditions. On the premise of having a large amount of valid data, the emergence of the recommendation system can effectively utilize these precious data wealth. On the user side , which can help users recommend movies they like more, improving user experience and user stickiness. On the corporate side, it can help movie companies and platforms better understand users’ needs and preferences, and provide movie content that is more in line with users’ tastes, thereby increasing movie box office and platform profitability. From the perspective of the entire film industry, it is also possible to increase the number of users watching movies by recommending suitable movies, increase the revenue and exposure of movies, and thereby promote the development of the film industry [5].
1.3 Current situation analysis
The recommendation system is a technology that can recommend personalized content to users based on their historical behavior and preferences. With the popularity of various Internet and mobile applications, recommendation systems have become an important part of major enterprises, providing users with a more personalized and high-quality service experience. There are different development statuses at home and abroad.
China's recommendation system market has experienced rapid development and has gradually become one of the largest recommendation system markets in the world.
