This book provides a broad introduction to search engines by
integrating five different perspectives on Web search and search
engines that are usually dealt with separately: the technical
perspective, the user perspective, the internet-based research
perspective, the economic perspective, and the societal
perspective. After a general introduction to the topic, two
foundational chapters present how search tools can cover the Web's
content and how search engines achieve this by crawling and
processing the found documents. The next chapter on user behavior
covers how people phrase their search queries and interact with
search engines. This knowledge builds the foundation for describing
how results are ranked and presented. The following three chapters
then deal with the economic side of search engines, i.e., Google
and the search engine market, search engine optimization (SEO), and
the intermingling of organic and sponsored search results. Next,
the chapter on search skills presents techniques for improving
searches through advanced search interfaces and commands. Following
that, the Deep Web and how its content can be accessed is
explained. The two subsequent chapters cover ways to improve the
quality of search results, while the next chapter describes how to
access the Deep Web. Last but not least, the following chapter
deals with the societal role of search engines before the final
chapter concludes the book with an outlook on the future of Web
search. With this book, students and professionals in disciplines
like computer science, online marketing, or library and information
science will learn how search engines work, what their main
shortcomings are at present, and what prospects there are for their
further development. The different views presented will help them
to understand not only the basic technologies but also the
implications the current implementations have concerning economic
exploitation and societal impact.
"Web Search Engine Research", edited by Dirk Lewandowski, provides
an understanding of Web search engines from the unique perspective
of Library and Information Science. The book explores a range of
topics including retrieval effectiveness, user satisfaction, the
evaluation of search interfaces, the impact of search on society,
reliability of search results, query log analysis, user guidance in
the search process, and the influence of search engine optimization
(SEO) on results quality. While research in computer science has
mainly focused on technical aspects of search engines, LIS research
is centred on users' behaviour when using search engines and how
this interaction can be evaluated. LIS research provides a unique
perspective in intermediating between the technical aspects, user
aspects and their impact on their role in knowledge acquisition.
This book is directly relevant to researchers and practitioners in
library and information science, computer science, including Web
researchers.
In an era in which social integration is increasingly predicated on
digital participation, barrier-free access to the Internet and key
information systems has become vital for equal participation in
social life. This volume presents the basic theory and practice of
designing barrier-free information systems, which are a key element
of an inclusive information society.
