Geographic knowledge graphs can have an important role in delivering interoperability, accessibility and the demands of conceptualization in geographic information science (GIS). However, the massive amount of accompanying information and the enormous diversity of geographic knowledge graphs limits their applicability and hinders the widespread adoption of this useful structured knowledge. This book, Geographic Knowledge Graph Summarization, focuses on the ways in which geographic knowledge graphs can be digested and summarized. Such a summarization would relieve the burden of information overload for end users and reduce data storage, as well as speeding up queries and eliminating ‘noise’. The book introduces the general concept of geospatial inductive bias and explains the different ways in which this idea can be used in the summarization of geographic knowledge graphs.The book breaks up the task of summarization into separate but related components, and after an introduction and a brief overview of concepts and theories, Chapters 3, 4 and 5 explore hierarchical place type structure, multimedia leaf nodes, and general relation and entity components respectively. Chapter 6 presents a spatial knowledge map interface which illustrates the effectiveness of summarization.The book integrates top-down knowledge engineering and bottom-up knowledge learning methods, and will do much to promote awareness of this fascinating area and related issues.

This book documents and analyses the differentiated control policies, the determinant factors behind, social resilience, and international relations during the pandemic from a comparative perspective in a facts-based, data-supporting manner. The intermittent outbreak of cases, public sentiments after long anxiety, questions over the efficacy of vaccines, have forced governments as well as the public to rethink differing approaches and policies in the combat against not just COVID, but the delta variant. In this context, this book establishes itself as a timely product, perhaps the first of its kind, to provide a widely covered individual country-based observation of policies, with an emphasis on multidimensional determinant factors behind the policies. A comparative study of social resilience during the pandemic constitutes another highlight of the book. The different policies tested social resilience differently in parameters such as mortality rates, vaccination coverage, social mobility, travel arrangements, trust in government, and general human development. Above and beyond observations and analyses at local and national levels, this book expands its scope to incorporate international relations, contemplating over the impacts of the pandemic on international relations, power shifts, and new world/global orders, crystallized in the indisputable rise of China.

This book highlights key technologies of signal processing in pulsar-based navigation. It discusses the modeling, simulation, acquisition, and correction of relativistic effects of signals from X-ray pulsars. It demonstrates the methods of contour reconstruction and denoising, and introduces the concept and methods of the average contour. The performance of the phase measurement methods using signal contour is analyzed. The role of wavelets and bispectral methods in the denoising of pulsar signals is discussed. The measurements of pulsar signals’ arriving time are looked into from the perspective of time series. The book is intended for researchers and engineers interested in pulsar-based navigation. It is also a good reference source for senior undergraduates and postgraduate students majoring in navigation and signal processing.
