Professor Xihua Cao (1920-2005) was a leading scholar at East China Normal University (ECNU) and a famous algebraist in China. His contribution to the Chinese academic circle is particularly the formation of a world-renowned "ECNU School" in algebra, covering research areas include algebraic groups, quantum groups, algebraic geometry, Lie algebra, algebraic number theory, representation theory and other hot fields. In January 2020, in order to commemorate Professor Xihua Cao's centenary birthday, East China Normal University held a three-day academic conference. Scholars at home and abroad gave dedications or delivered lectures in the conference. This volume originates from the memorial conference, collecting the dedications of scholars, reminiscences of family members, and 16 academic articles written based on the lectures in the conference, covering a wide range of research hot topics in algebra. The book shows not only scholars' respect and memory for Professor Xihua Cao, but also the research achievements of Chinese scholars at home and abroad.

The majority of technology transfer studies done today are derived from Economics and Management Sciences, and there are relatively few studies that examine the geographical concerns of technology transfer from a glocal perspective. Geography of Technology Transfer in China fills the gap by aiming to discover the geographical character of technology transfer and its determinants from the interaction in both global and local scales, which involves the study of innovation geography, economic geography, urban economics, and regional economics.The chapters included in this book present a clear structure of a series of studies performed both theoretically and empirically. The research begins by constructing an analytic framework for urban technology transfer study and abstracts the study target from technological innovation subjects to cities, along with establishing the structure system, the dimension system, and the effect system of urban technology transfer research. This then develops an initial conceptual framework for urban technology transfer research. In addition, it analyses the hierarchy of China's urban technology innovation system and the segmentation of the technology transfer market, from the perspective of technology transfer. All in all, the book aspires to depict the spatial evolution of China's technological innovation system and technology transfer system from a city size perspective, thereby realising the spatial scale of technology transfer study.

Roads are essential components of a city. Despite their increasing importance in our daily lives, modeling and simulating road networks is challenging due to their dynamic and complex nature. The underlying order and patterns of the seemingly chaotic and diverse physical patterns of roads are still unclear. Furthermore, there is a knowledge gap regarding the relationships between the size, scale, shape, structure, and space of road networks.This book presents the state-of-the-art in computational methods for modeling the topological structure of road networks. Each chapter focuses on a specific aspect of this topology and provides models, indicators, and empirical studies of road network structures. The book includes six types of structural models and three types of spatial simulation models to help understand the topological structural complexity of road networks. The appendices include several examples of road networks and their universal scale-free patterns.This interdisciplinary book is helpful for individuals interested in spatial modeling, network analysis, transportation geography, and urban studies. It is also a fundamental resource for modeling and computing spatial complex systems. The book is suitable for undergraduate, graduate, and professional researchers interested in geographic modeling and urban design. The text is written with moderate mathematical detail to enhance comprehension of the concepts and principles presented. The use of maps, graphics, and examples makes the modeling and computational processes more intuitive.

This book provides a comprehensive introduction on opinion analysis for online reviews. It offers the newest research on opinion mining, including theories, algorithms and datasets. A new feature presentation method is highlighted for sentiment classification. Then, a three-phase framework for sentiment classification is proposed, where a set of sentiment classifiers are selected automatically to make predictions. Such predictions are integrated via ensemble learning. Finally, to solve the problem of combination explosion encountered, a greedy algorithm is devised to select the base classifiers.

Data uncertainty widely exists in many applications, and an uncertain data stream is a series of uncertain tuples that arrive rapidly. However, traditional techniques for deterministic data streams cannot be applied to deal with data uncertainty directly due to the exponential growth of possible solution space.This book provides a comprehensive overview of the authors' work on querying and mining uncertain data streams. Its contents include some important discoveries dealing with typical topics such as top-k query, ER-Topk query, rarity estimation, set similarity, and clustering.Querying and Mining Uncertain Data Streams is written for professionals, researchers, and graduate students in data mining and its various related fields.

Data analysis is of upmost importance in the mining of big data, where knowledge discovery and inference are the basis for intelligent systems to support the real world applications. However, the process involves knowledge acquisition, representation, inference and data, Bayesian network (BN) is the key technology plays a key role in knowledge representation, in order to pave way to cope with incomplete, fuzzy data to solve the real-life problems.This book presents Bayesian network as a technology to support data-intensive and incremental learning in knowledge discovery, inference and data fusion in uncertain environment.

Online social networking sites like Facebook, LinkedIn, and Twitter, offer millions of members the opportunity to befriend one another, send messages to each other, and post content on the site — actions which generate mind-boggling amounts of data every day.To make sense of the massive data from these sites, we resort to social media mining to answer questions like the following:Social media shatters the boundaries between the real world and the virtual world. We can now integrate social theories with computational methods to study how individuals interact with each other and how social communities form in bipartite and signed networks. The uniqueness of social media data calls for novel data mining techniques that can effectively handle user generated content with rich social relations. The study and development of these new techniques are under the purview of social media mining, an emerging discipline under the umbrella of data mining. Social Media Mining is the process of representing, analyzing, and extracting actionable patterns from social media data.Related Link(s)
