Download or read book Understanding Human Dynamics from Large scale Location centric Social Media Data written by Dingqi Yang and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human dynamics is an essential aspect of human centric computing. As a transdisciplinary research field, it focuses on understanding the underlying patterns, relationships, and changes of human behavior. By exploring human dynamics, we can understand not only individual's behavior, such as a presence at a specific place, but also collective behaviors, such as social movement. Understanding human dynamics can thus enable various applications, such as personalized location based services. However, before the availability of ubiquitous smart devices (e.g., smartphones), it is practically hard to collect large-scale human behavior data. With the ubiquity of GPS-equipped smart phones, location based social media has gained increasing popularity in recent years, making large-scale user activity data become attainable. Via location based social media, users can share their activities as real-time presences at Points of Interests (POIs), such as a restaurant or a bar, within their social circles. Such data brings an unprecedented opportunity to study human dynamics. In this dissertation, based on large-scale location centric social media data, we study human dynamics from both individual and collective perspectives. From individual perspective, we study user preference on POIs with different granularities and its applications in personalized location based services, as well as the spatial-temporal regularity of user activities. From collective perspective, we explore the global scale collective activity patterns with both country and city granularities, and also identify their correlations with diverse human cultures.
Download or read book Understanding Human Perception of Place with Geospatial Data Science written by Yuhao Kang (Ph.D.) and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This doctoral dissertation research is designed to advance our understanding of human perceptions of places using geospatial data science. Measuring human perceptions of places, such as how safe and lively a neighborhood is, is crucial for investigating the human sense of place and for furthering our knowledge of human-environment relationships. However, previous studies using interpretive approaches (e.g., interviews, questionnaires) to measure human perceptions of places face challenges such as high labor intensity, long update periods, and geographic scale limitations. Geospatial data science, including the usage of multiple sources of urban big data (e.g., street view imagery, human mobility) and the development of advanced geospatial artificial intelligence (GeoAI), provides unprecedented opportunities for researchers to not only model objective geographic phenomenon but also assess subjective human perceptions of places from a variety of dimensions (e.g., lively, safe, wealthy).Here, we first introduce a computational framework to measure human perceptions of places from a data-driven perspective. We employ geocomputational approaches to assess human perceptions of places with large-scale street view images and advanced GeoAI approaches. By comparing with conventional interpretive approaches, we illustrate the effectiveness of geospatial data science for measuring human perceptions of places and acknowledge its potential biases and challenges. We then explore what and how various urban design and environmental factors may affect people's place perceptions to inform city developments. After that, we demonstrate how human subjective perceptions of place might be integrated into place-based spatial analytics and highlight the critical role of human place perception in understanding human-environment interactions. This dissertation is developed based on the author's three peer-reviewed journal articles and has been arranged as chapters 4, 5, and 6. This work makes contributions to the broader fields of GIScience, geography, and urban planning. First, it shows how socioeconomic and environmental factors influence human perceptions of places and reveals the complex interactions between human activities and the physical environment. Second, it provides insights and decision-making suggestions for urban planners and governments toward building safer, livelier, and wealthier communities and cities. Third, it illustrates how humanistic insights can be integrated into geospatial data science and offers insights for addressing ethical issues in the development of GIScience.
Download or read book Social Sensing and Big Data Computing for Disaster Management written by Zhenlong Li and published by Routledge. This book was released on 2020-12-17 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social Sensing and Big Data Computing for Disaster Management captures recent advancements in leveraging social sensing and big data computing for supporting disaster management. Specifically, analysed within this book are some of the promises and pitfalls of social sensing data for disaster relevant information extraction, impact area assessment, population mapping, occurrence patterns, geographical disparities in social media use, and inclusion in larger decision support systems. Traditional data collection methods such as remote sensing and field surveying often fail to offer timely information during or immediately following disaster events. Social sensing enables all citizens to become part of a large sensor network which is low cost, more comprehensive, and always broadcasting situational awareness information. However, data collected with social sensing is often massive, heterogeneous, noisy, and unreliable in some aspects. It comes in continuous streams, and often lacks geospatial reference information. Together, these issues represent a grand challenge toward fully leveraging social sensing for emergency management decision making under extreme duress. Meanwhile, big data computing methods and technologies such as high-performance computing, deep learning, and multi-source data fusion become critical components of using social sensing to understand the impact of and response to the disaster events in a timely fashion. This book was originally published as a special issue of the International Journal of Digital Earth.
Download or read book Geospatial Technologies and Geography Education in a Changing World written by Osvaldo Muñiz Solari and published by Springer. This book was released on 2015-08-31 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an initiative presented by the Commission on Geographical Education of the International Geographical Union. It focuses particularly on what has been learned from geospatial projects and research from the past decades of implementing geospatial technologies (GST) in formal and informal education. The objective of this publication is to inform an international audience of teachers, professionals, scholars, and policymakers about the state of the art and prospects of geospatial practices (GPs) as organized activities that use GST and lessons learned in relation to geographical education. GST make up an advanced body of knowledge developed by practitioners of geographic information systems (GIS), remote sensing (RS), global positioning systems, (GPS), and digital cartography (DC). GST have long been applied in many different sectors; however, their first use in higher education began in the early 1980s and then diffused to secondary schools during the 1990s. Starting with GIS and RS, it evolved into a much broader context, as GST expanded to include GPS and DC with new communication technologies and Internet applications. GST have been used around the world as a combination of tools and special techniques to make research, teaching, and learning more effective.

Download or read book Crowdsourcing Geographic Knowledge written by Daniel Sui and published by Springer Science & Business Media. This book was released on 2012-08-10 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of volunteered geographic information is part of a profound transformation in how geographic data, information, and knowledge are produced and circulated. By situating volunteered geographic information (VGI) in the context of big-data deluge and the data-intensive inquiry, the 20 chapters in this book explore both the theories and applications of crowdsourcing for geographic knowledge production with three sections focusing on 1). VGI, Public Participation, and Citizen Science; 2). Geographic Knowledge Production and Place Inference; and 3). Emerging Applications and New Challenges. This book argues that future progress in VGI research depends in large part on building strong linkages with diverse geographic scholarship. Contributors of this volume situate VGI research in geography’s core concerns with space and place, and offer several ways of addressing persistent challenges of quality assurance in VGI. This book positions VGI as part of a shift toward hybrid epistemologies, and potentially a fourth paradigm of data-intensive inquiry across the sciences. It also considers the implications of VGI and the exaflood for further time-space compression and new forms, degrees of digital inequality, the renewed importance of geography, and the role of crowdsourcing for geographic knowledge production.

Download or read book Atlas of Knowledge written by Katy Borner and published by MIT Press. This book was released on 2015-03-20 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The power of mapping: principles for visualizing knowledge, illustrated by many stunning large-scale, full-color maps. Maps of physical spaces locate us in the world and help us navigate unfamiliar routes. Maps of topical spaces help us visualize the extent and structure of our collective knowledge; they reveal bursts of activity, pathways of ideas, and borders that beg to be crossed. This book, from the author of Atlas of Science, describes the power of topical maps, providing readers with principles for visualizing knowledge and offering as examples forty large-scale and more than 100 small-scale full-color maps. Today, data literacy is becoming as important as language literacy. Well-designed visualizations can rescue us from a sea of data, helping us to make sense of information, connect ideas, and make better decisions in real time. In Atlas of Knowledge, leading visualization expert Katy Börner makes the case for a systems science approach to science and technology studies and explains different types and levels of analysis. Drawing on fifteen years of teaching and tool development, she introduces a theoretical framework meant to guide readers through user and task analysis; data preparation, analysis, and visualization; visualization deployment; and the interpretation of science maps. To exemplify the framework, the Atlas features striking and enlightening new maps from the popular “Places & Spaces: Mapping Science” exhibit that range from “Key Events in the Development of the Video Tape Recorder” to “Mobile Landscapes: Location Data from Cell Phones for Urban Analysis” to “Literary Empires: Mapping Temporal and Spatial Settings of Victorian Poetry” to “Seeing Standards: A Visualization of the Metadata Universe.” She also discusses the possible effect of science maps on the practice of science.
