Information Retrieval （IR） is concerned with the effective and efficient retrieval of information based on its semantic content. The central problem in IR is the quest to find the set of relevant documents， among a large collection containing the information sought， satisfying a user's information need usually expressed in a natural language query. Documents may be objects or items in any medium： text， image， audio， or indeed a mixture of all three. This book presents 12 revised lectures given at the Third European Summer School in Information Retrieval， ESSIR 2000， held at the Villa Monastero， Varenna， Italy， in September 2000. The first part of the book is devoted to the foundation of IR and related areas; the second part on advanced topics addresses various current issues， from usability aspects to Web searching and browsing.
