The motivation determines the demand. The information demand of online game virtual community is different because of the user's participation motivation. According to nickyee's research, the user's participation motivation of large-scale online multiplayer games can be divided into achievement needs, social needs, immersion, etc. by collecting user information, the user's achievement, economic or social needs can be met. Information and information requirements [4].For information behavior research, the most important thing is the definition of information and the identification of information needs. Although there are many definitions of information, the author believes that in the study of online game virtual community, we should adopt dervin's definition of information, that is to say, information and information demand are not "things" in a formal way. Individuals feel different because of different experiences. They use information and communication to define and construct reality. [5]For the users of online game virtual community, the form of information is diverse, for example, it can be text information, video image information, text information, symbol information, and even some information can be expressed through the action of the role. It is through these diverse and rich information that participants understand the virtual community of online games and survive in the virtual community of online games.Information collection and sorting.In a narrow sense, information collection and collation refers to querying, retrieving, identifying and using information. In a broad sense, information collection and collation is the collection and collation of various kinds of information for users to face complex problems, and make decisions through information. According to the model developed by Kuhlthau, the information query process includes six steps, which are initiation (worry), selection (optimism), exploration (confusion), structure (clarity), collection (certainty), expression (mitigation). In the virtual community of online games, users' information behaviors include information browsing, information selection, information exploration, information arrangement, information expression, etc.Content creation and knowledge sharing.In the virtual online game, through information query and sorting, participants are active in various kinds of information. Due to different experiences of participants, they are getting different knowledge through this information. When participants express these knowledge, they create different information content. Content creation can share knowledge is the advanced form of user information behavior in virtual community. Knowledge share refers to the process of knowledge diffusion from knowledge owner to knowledge receiver. Here, knowledge refers to the information, data, image, image, value standard and other symbolic products of society sorted out by human thinking. The shared knowledge includes not only the clear knowledge that can be encoded, but also the tacit knowledge that is inseparable with personal experience and background. Explicit knowledge is a systematic and structured knowledge, which can be easily communicated by means of data or coding, and can be easily and formally transmitted by a single individual. Tacit knowledge is not easy and convenient to communicate and spread, it includes intangible factors such as personal information, experience and value.Online games are attracting a large number of users to participate in them. With the development of technology and society, online games have become an important living space for young people. Online games are affecting the young generation. The information in online game space has many characteristics, such as economy, social value, entertainment value and so on. The research on the information behavior of online game users is conducive to providing better information services and strengthening information supervision. At the same time, there are many positive elements in online games, such as the active participation of users in building cultural products, etc. to grasp the user participation motivation and information behavior of online games is conducive to the vigorous development of cyberspace. Therefore, the virtual space of online games has broad development potential, and the research of user information behavior between online games is of great significance.
