Abstract

With the rapid growth of web-based applications, such as search engines, Facebook, and Twitter, the development of effective and personalized information retrieval techniques and of user interfaces is essential. The amount of shared information and of social networks has also considerably grown, requiring metadata for new sources of information, like Wikipedia and ODP. These metadata have to provide classification information for a wide range of topics, as well as for social networking sites like Twitter, and Facebook, each of which provides additional preferences, tagging information and social contexts. Due to the explosion of social networks and other metadata sources, it is an opportune time to identify ways to exploit such metadata in IR tasks such as user modeling, query understanding, and personalization, to name a few. Although the use of traditional metadata such as html text, web page titles, and anchor text is fairly well-understood, the use of category information, user behavior data, and geographical information is just beginning to be studied. This book is intended for scientists and decision-makers who wish to gain working knowledge about search engines in order to evaluate available solutions and to dialogue with software and data providers.

Rez. in: JASIST 58(2007) no.7, S.1066-1067 (X. Zhu u. J. Liao): "The user, without whom any product or service would be nothing, plays a very important role during the whole life cycle of products or services. The user's involvement should be from the very beginning, not just after products or services are ready to work. According to ISO 9241-11: 1998, Part 11, Usability refers to "the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of user." As an academic topic of human-computer interaction, Web usability has been studied widely for a long time. This classroom-oriented book, bridging academia and the educational community, talks about Web usability in a student-friendly fashion. It outlines not only the methodology of user-centered Web site design but also details the methods to implement at every stage of the methodology. That is, the book presents the user-centered Web-design approach from both macrocosm and microcosm points of view, which makes it both recapitulative and practical. The most important key word in Web Usability is "user-centered," which means Web developers should not substitute their own personal preferences for the users' needs. The book classifies Web sites into five types: E-commerce, informational, entertainment, community, and intranet. Since the methods used during Web development differ somewhat depending on the type of Web site, it is necessary to have a classification in advance. With Figure 1.3 on p. 17, the book explains the whole user-centered Webdevelopment life cycle (called "methodology" in this book review), which provides a clear path for Web development that is easy to understand, remember, and perform. Since all the following chapters are based on the methodology, a clear presentation of it is paramount. The table on p. 93 summarizes concisely all types of methods for requirements gathering and their advantages and disadvantages. According to this table, appropriate methods can be easily chosen for different Web site development projects. As the author remarked, "requirements gathering is central to the concept of user-centered design," (p. 98) and "one of the hallmarks of user-centered design is usability testing" (p. 205). Stage 2 (collect user requirements) and Stage 5 (perform usability testing) of the user-centered Web-development life cycle are the two stages with the most user involvement: however, this does not mean that all other stages are user unrelated. For example, in Stage 4 (create and modify physical design), frame is not suggested to be used just because most users are unfamiliar with the concept of frame (p. 201). Note that frequently there are several rounds of usability testing to be performed in the four case studies, and some of them are performed before the physical-design stage or even the conceptual-design stage, which embodies the idea of an iterative design process.
