This chapter serves as an introduction to the book on User Community Discovery, setting the scene for the presentation in the rest of the book of various methods for the discovery of user communities in the social Web. In this context, the current chapter introduces the various types of user community, as they appeared in the early days of the Web, and how they converged to the common concept of active user community in the social Web. In this manner, the chapter aims to clarify the use of terminology in the various research areas that study user communities. Additionally, the main approaches to discovering user communities are briefly introduced and a number of new challenges for community discovery in the social Web are highlighted. In particular we emphasize the complexity of the networks that are constructed among users and other entities in the social Web. Social networks are typically multi-modal, i.e. containing different types of entity, multi-relational, i.e. comprising different relation types, and dynamic, i.e. changing over time. The complexity of the networks calls for new versatile and efficient methods for community discovery. Details about such methods are provided in the rest of the book.
