Information Markets is a compendium of the i-commerce, the commerce with digital information, content as well as software. Information Markets is a comprehensive overview of the state of the art of economic and information science endeavors on the markets of digital information. It provides a strategic guideline for information providers how to analyse their market environment and how to develop possible strategic actions. It is a book for information professionals, both for students of LIS (Library and Information Science), CIS (Computer and Information Science) or Information Management curricula and for practitioners as well as managers in these fields.

Scientific communication depends primarily on publishing in journals. The most important indicator to determine the influence of a journal is the Impact Factor. Since this factor only measures the average number of citations per article in a certain time window, it can be argued that it does not reflect the actual value of a periodical. This book defines five dimensions, which build a framework for a multidimensional method of journal evaluation. The author is winner of the Eugene Garfield Doctoral Dissertation Scholarship 2011.

The scope of this volume will encompass a collection of research papers related to indexing and retrieval of online non-text information. In recent years, the Internet has seen an exponential increase in the number of documents placed online that are not in textual format. These documents appear in a variety of contexts, such as user-generated content sharing websites, social networking websites etc. and formats, including photographs, videos, recorded music, data visualizations etc. The prevalence of these contexts and data formats presents a particularly challenging task to information indexing and retrieval research due to many difficulties, such as assigning suitable semantic metadata, processing and extracting non-textual content automatically, and designing retrieval systems that "speak in the native language" of non-text documents.

This collected volume gathers a broad spectrum of social science and information science articles about Facebook. It looks into facets of users, such as age, sex, and culture, and into facets of use, e.g. privacy behavior after the Snowden affair, unfriending on Facebook, or Facebook addiction, as well as into quality perceptions. Written by leading scholars investigating the impact of Web 2.0., this volume is highly relevant for social media researchers, information scientists, and social scientists, and, not least, for everyone interested in Facebook-related topics.

The high degree of internet penetration and its social (and linguistic) effects evidently influence how people, and especially the highly susceptible younger generations, use language. The primary aim of the book is not only to identify the characteristic features of the digital language variety (this has already been done by several works) but to examine how digital communication affects the language of other mediums of communication: orality, handwritten texts, digitally created but not digitally perceived, that is printed texts, including in particular advertisements (which quickly respond to linguistic change). Naturally, the book presents the characteristics of the digital language variety (and coins the term digilect) but only to give a framework to the impact analysis. It is important to document changes in progress and thus direct attention to potential outcomes. The current linguistic change is different from previous ones primarily in its speed and form of spreading, and it not only brings innovative grammatical forms and writing/spelling solutions but may also have far-reaching cultural and educational consequences in the long run.

The term smart city has become a buzzword. City planners develop ubiquitous connectivity through Wi-Fi hotspots, establish science parks, introduce bike and car sharing, and push entrepreneurship. All this is happening under the flagship of becoming a knowledge city. This book investigates the digital and cognitive infrastructure of 31 cities and how they meet the demands of the knowledge society in an increasingly digitized environment.

By the time refugees flee from their home country, they likewise leave behind their former life, their relatives and acquaintances. Building a new life in their country of destination requires them to learn a foreign language and adjust to a new culture. Obviously, their information behavior as well as ICT and digital media usage adapt to these challenging circumstances.What kind of information are refugees looking for? Who do they communicate with? What ICT, social and digital media do they apply? What are their motives to use particular devices or services, from Facebook and WhatsApp to YouTube and TikTok? Are gender- as well as age-dependent differences to be observed?To answer these questions, data have been collected through an online questionnaire, interviews, as well as a content analysis of an online platform for refugees.

The publication and distribution of scientific results is of major importance for the functioning of an information society and the tackling of the complex challenges the world faces today. It is not only scholars who rely on scientific publications to advance research but also the general public which demands scientific knowledge for its forthcoming.Major suppliers of scientific knowledge are the researchers themselves, science communicators and science journalists – each of which choose their very own approaches to selection, presentation and communication of science, often depending on the target group. Although different in their goals and approaches, digital media in particular has led to great overlaps which result in interwoven relationships equally affecting both external and internal forms of science communication.This edited book describes, quantifies and critically discusses the interplay between publisher- and journalism-driven science communication and its effect on the scholarly communication system, especially on the measures of impact evaluation. It is of major interest to researchers from science of science, bibliometrics, science communication, and journalism studies.

In Web 2.0 users not only make heavy use of Col-laborative Information Services in order to create, publish and share digital information resources - what is more, they index and represent these re-sources via own keywords, so-called tags. The sum of this user-generated metadata of a Collaborative Information Service is also called Folksonomy. In contrast to professionally created and highly struc-tured metadata, e.g. subject headings, thesauri, clas-sification systems or ontologies, which are applied in libraries, corporate information architectures or commercial databases and which were developed according to defined standards, tags can be freely chosen by users and attached to any information resource. As one type of metadata Folksonomies provide access to information resources and serve users as retrieval tool in order to retrieve own re-sources as well as to find data of other users.The book delivers insights into typical applications of Folksonomies, especially within Collaborative Information Services, and discusses the strengths and weaknesses of Folksonomies as tools of knowl-edge representation and information retrieval. More-over, it aims at providing conceptual considerations for solving problems of Folksonomies and presents how established methods of knowledge representa-tion and models of information retrieval can successfully be transferred to them.

The main purpose of this book is to sum up the vital and highly topical research issue of knowledge representation on the Web and to discuss novel solutions by combining benefits of folksonomies and Web 2.0 approaches with ontologies and semantic technologies. The book contains an overview of knowledge representation approaches in past, present and future, introduction to ontologies, Web indexing and in first case the novel approaches of developing ontologies.
