ABSTRACT
Note that in Chapter 3 we briefly discussed data, information, and knowledge management and then described some of the security issues. Data is managed by a data manager. Information is extracted from the data, and knowledge is about understanding the information and taking actions. Data-management technologies include database management and data administration. Information-management technologies include multimedia information management and collaborative information management. Knowledge management is about reusing the knowledge and expertise of an organization to improve profits and other benefits. In this chapter we will examine in more detail security issues for data, information, and knowledge management and then discuss how semantic Web technologies may be applied for managing data, information, and knowledge.
