SYNTHESIS LECTURES ON INFORMATION CONCEPTS RETR...

Everybody knows what relevance is. It is a ya'know notion  concept  idea-no need to explain
whatsoever. Searching for relevant information using information technology (IT) became a
ubiquitous activity in contemporary information society. Relevant information means information
that pertains to the matter or problem at hand-it is directly connected with effective
communication. The purpose of this book is to trace the evolution and with it the history of
thinking and research on relevance in information science and related fields from the human
point of view. The objective is to synthesize what we have learned about relevance in several
decades of investigation about the notion in information science. This book deals with how
people deal with relevance-it does not cover how systems deal with relevance  it does not deal
with algorithms. Spurred by advances in information retrieval (IR) and information systems of
various kinds in handling of relevance  a number of basic questions are raised: But what is
relevance to start with? What are some of its properties and manifestations? How do people
treat relevance? What affects relevance assessments? What are the effects of inconsistent human
relevance judgments on tests of relative performance of different IR algorithms or approaches?
These general questions are discussed in detail.
