This book discusses various aspects of text data mining. Unlike other books that focus on machine learning or databases, it approaches text data mining from a natural language processing (NLP) perspective. The book offers a detailed introduction to the fundamental theories and methods of text data mining, ranging from pre-processing (for both Chinese and English texts), text representation and feature selection, to text classification and text clustering. It also presents the predominant applications of text data mining, for example, topic modeling, sentiment analysis and opinion mining, topic detection and tracking, information extraction, and automatic text summarization. Bringing all the related concepts and algorithms together, it offers a comprehensive, authoritative and coherent overview. Written by three leading experts, it is valuable both as a textbook and as a reference resource for students, researchers and practitioners interested in text data mining. It can also be used for classes on text data mining or NLP.

Discover the secrets of how giant bridges stand up A perfect STEM resource for young engineers. Have you ever wondered how a suspension bridge carries heavy cars? Or how bridge builders overcome deep water and strong winds? Bridges introduces young readers to the fascinating world of structural engineering. Through detailed illustrations and clear explanations, children will learn: The basic principles of bridge construction. How modern technology solves impossible engineering challenges. Real-world examples of record-breaking bridges (featuring spectacular modern bridges from China). Ideal for curious minds aged 7-9 who love building blocks, Lego, and understanding how things work. This book combines science, technology, and architectural beauty to inspire the next generation of civil engineers.

This book introduces the engineering application of the discrete element method (DEM), especially the simulation analysis of the typical equipment (scraper conveyor, coal silos, subsoiler) in the coal and agricultural machinery. In this book, the DEM is applied to build rigid and loose coupling model, and the kinematic effect of the bulk materials, the mechanical effect of the interaction between the bulk materials, and the mechanical equipment in the operation process of the relevant equipment are studied. On this basis, the optimization design strategy of the relevant structure is proposed. This book effectively promotes the application of DEM in engineering, analyzes the operation state, failure mechanism, and operation effect of related equipment in operation, and provides theoretical basis for the optimal design of equipment. The book is intended for undergraduate and graduate students who are interested in mechanical engineering, researchers investigating coal and agriculturalmachinery, and engineers working on designing related equipments.
