Abstract

With the ongoing digitization and virtualization of goods, services and living environments, information science reflects on the potential changes within the information society. While some parts of the community proclaim a revolutionary shift not only in the way we approach information and information systems, but also in the way society constitutes itself, other state that while the applications and interfaces adapt to advances in information technology, the underlying principles for human interactions with informations remain the same. In the ISI 2017 proceedings, contributions on the development of innovative information spaces and services, on analyses of human-computer interactions in physical or virtual inforamtion spaces and on the role of information science and its research endeavors are included.

Abstract

Cartographic maps have guided our explorations for centuries, allowing us to navigate the world. Science maps have the potential to guide our search for knowledge in the same way, helping us navigate, understand, and communicate the dynamic and changing structure of science and technology. Allowing us to visualize scientific results, science maps help us make sense of the avalanche of data generated by scientific research today. Atlas of Science, features more than thirty full-page science maps, fifty data charts, a timeline of science-mapping milestones, and 500 color images; it serves as a sumptuous visual index to the evolution of modern science and as an introduction to "the science of science"--charting the trajectory from scientific concept to published results. Atlas of Science, based on the popular exhibit "Places & Spaces: Mapping Science," describes and displays successful mapping techniques. The heart of the book is a visual feast: Claudius Ptolemy's Cosmographia World Map from 1482; a guide to a PhD thesis that resembles a subway map; "the structure of science" as revealed in a map of citation relationships in papers published in 2002; a periodic table; a history flow visualization of the Wikipedia article on abortion; a globe showing the worldwide distribution of patents; a forecast of earthquake risk; hands-on science maps for kids; and many more. Each entry includes the story behind the map and biographies of its makers. Not even the most brilliant minds can keep up with today's deluge of scientific results. Science maps show us the landscape of what we know. Exhibition Ongoing National Science Foundation, Washington, D.C.

Abstract

Information Architecture is about organizing and simplifying information, designing and integrating information spaces/systems, and creating ways for people to find and interact with information content. Its goal is to help people understand and manage information and make right decisions accordingly. In the ever-changing social, organizational and technological contexts, Information Architects not only design individual information spaces (e.g., individual websites, software applications, and mobile devices), but also tackle strategic aggregation and integration of multiple information spaces across websites, channels, modalities, and platforms. Not only they create predetermined navigation pathways, but also provide tools and rules for people to organize information on their own and get connected with others. Information Architects work with multi-disciplinary teams to determine the user experience strategy based on user needs and business goals, and make sure the strategy gets carried out by following the user-centered design (UCD) process via close collaboration with others. Drawing on the author(s) extensive experience as HCI researchers, User Experience Design practitioner, and Information Architecture instructors, this book provides a balanced view of the IA discipline by applying the IA theories, design principles and guidelines to the IA and UX practices. It also covers advanced topics such as Enterprise IA, Global IA, and Mobile IA. In addition to new and experienced IA practitioners, this book is written for undergraduate and graduate level students in Information Architecture, Information Sciences, Human Computer Interaction, Information Systems and related disciplines.

Abstract

Visual Interfaces to Digital Libraries exploit the power of human vision and spatial cognition to help individuals mentally organize and electronically access and manage large and complex information spaces. They draw on progress in the field of information visualization and seek to shift the users' mental load from slow reading to faster perceptual processes such as visual pattern recognition.Based on two workshops, the book presents an introductory overview as well as a closing listing of the top ten problems in the area by the volume editors. Also included are 16 thoroughly reviewed and revised full papers organized in topical sections on visual interfaces to documents, document parts, document variants, and document usage data; visual interfaces to image and video documents; visualization of knowledge domains; cartographic interfaces to digital libraries; and a general framework.

Abstract

The Architecture of Cyberspace is aimed at students taking information management as a minor in their course as well as those who manage document collections but who are not professional librarians. The first part of this book looks at how users find documents and the problems they have; the second part discusses how to manage the information space using various tools such as classification and controlled vocabularies. It also explores the general issues of publishing, including legal considerations, as well the main issues of creating and managing archives. Supported by exercises and discussion questions at the end of each chapter, the book includes some sample assignments suitable for use with students of this subject. A glossary is also provided to help readers understand the specialised vocabulary and the key concepts in the design and assessment of information spaces.

Abstract

Information science has for a long time been drawing on the knowledge produced in psychology and related fields. This is reasonable, for the central issue in information science concerns individual users navigating information spaces such as libraries, databases, and the Internet, Thus, informations seeking is the fundamental problem in information science, while other problems, such as document representation, are subordinate. This book proposes a general theory of information seeking as a theoretical basis for information science

Content

LIS research and evaluation methodologies fell under the same scrutiny and systematization, particularly in the presentations employing multiple and mixed methodologies. Jaana Kekäläinen's and Kalervo Järvelin's proposal for a framework of laboratory information retrieval evaluation measures, applied along with analyses of information seeking and work task contexts, employed just such a mix. Marcia Bates pulled together Bradford's Law of Scattering of decreasingly relevant information sources and three information searching techniques (browsing, directed searching, and following links) to pose the question: what are the optimum searching techniques for the different regions of information concentrations? Jesper Schneider and Pia Borlund applied bibliometric methods (document co-citation, bibliographic coupling, and co-word analysis) to augment manual thesaurus construction and maintenance. Fredrik Åström examined document keyword co-occurrence measurement compared to and then combined with bibliometric co-citation analysis to map LIS concept spaces. Ian Ruthven, Mounia Lalmas, and Keith van Rijsbergen compared system-supplied query expansion terms with interactive user query expansion, incorporating both partial relevance assessment feedback (how relevant is a document) and ostensive relevance feedback (measuring when a document is assessed as relevant over time). Scheduled in the midst of the presentations were two stimulating panel and audience discussions. The first panel, chaired by Glynn Harmon, explored the current re-positioning of many library and information science schools by renaming themselves to eliminate the "library" word and emphasize the "information" word (as in "School of Information," "Information School," and schools of "Information Studies"). Panelists Marcia Bates, Harry Bruce, Toni Carbo, Keith Belton, and Andrew Dillon presented the reasons for name changes in their own information programs, which include curricular change and expansion beyond a "stereotypical" library focus, broader contemporary theoretical approaches to information, new clientele and markets for information services and professionals, new media formats and delivery models, and new interdisciplinary student and faculty recruitment from crossover fields. Sometimes criticized for over-broadness and ambiguity-and feared by library practitioners who were trained in more traditional library schools-renaming schools both results from and occasions a renewed examination of the definitions and boundaries of the field as a whole and the educational and research missions of individual schools.

Abstract

Developers of digital media require new skills in information design. Information designers developing web sites, software or online system interfaces, games and other digital media often overlook critical steps to ensure the usability of their product. This book introduces readers to both the theory and practice of the use of scenarios to create usable information spaces. Through practical applications - such as step-bystep guidelines for scenario development and case studies with analysis tools - the book outlines crucial steps to develop user and use scenarios to achieve competencies for and tools to implement prescribed tasks for user-oriented information design.

Abstract

This volume summarizes the author's work on social information seeking (SIS), and at the same time serves as an introduction to the topic. Sometimes also referred to as social search or social information retrieval, this is a relatively new area of study concerned with the seeking and acquiring of information from social spaces on the Internet. It involves studying situations, motivations, and methods involved in seeking and sharing of information in participatory online social sites, such as Yahoo! Answers, WikiAnswers, and Twitter, as well as building systems for supporting such activities. The first part of the book introduces various foundational concepts, including information seeking, social media, and social networking. As such it provides the necessary basis to then discuss how those aspects could intertwine in different ways to create methods, tools, and opportunities for supporting and leveraging SIS. Next, Part II discusses the social dimension and primarily examines the online question-answering activity. Part III then emphasizes the collaborative aspect of information seeking, and examines what happens when social and collaborative dimensions are considered together. Lastly, Part IV provides a synthesis by consolidating methods, systems, and evaluation techniques related to social and collaborative information seeking. The book is completed by a list of challenges and opportunities for both theoretical and practical SIS work. The book is intended mainly for researchers and graduate students looking for an introduction to this new field, as well as developers and system designers interested in building interactive information retrieval systems or social/community-driven interfaces.

Abstract

Software has become a key component of contemporary life and algorithmic techniques that rank, classify, or recommend anything that fits into digital form are everywhere. This book approaches the field of information ordering conceptually as well as historically. Building on the philosophy of Gilbert Simondon and the cultural techniques tradition, it first examines the constructive and cumulative character of software and shows how software-making constantly draws on large reservoirs of existing knowledge and techniques. It then reconstructs the historical trajectories of a series of algorithmic techniques that have indeed become the building blocks for contemporary practices of ordering. Developed in opposition to centuries of library tradition, coordinate indexing, text processing, machine learning, and network algorithms instantiate dynamic, perspectivist, and interested forms of arranging information, ideas, or people. Embedded in technical infrastructures and economic logics, these techniques have become engines of order that transform the spaces they act upon.
