Bücher von Chi Wang

The "e;big data"e; era is characterized by an explosion of information in the form of digital data collections, ranging from scientific knowledge, to social media, news, and everyone's daily life. Examples of such collections include scientific publications, enterprise logs, news articles, social media, and general web pages. Valuable knowledge about multi-typed entities is often hidden in the unstructured or loosely structured, interconnected data. Mining latent structures around entities uncovers hidden knowledge such as implicit topics, phrases, entity roles and relationships. In this monograph, we investigate the principles and methodologies of mining latent entity structures from massive unstructured and interconnected data. We propose a text-rich information network model for modeling data in many different domains. This leads to a series of new principles and powerful methodologies for mining latent structures, including (1) latent topical hierarchy, (2) quality topical phrases, (3) entity roles in hierarchical topical communities, and (4) entity relations. This book also introduces applications enabled by the mined structures and points out some promising research directions.

Wang emigrated from China to the United States in 1949. He quickly made a life for himself and became active in the development of Sino-American relations. Wang's memoirs provide unique Chinese insight in the development of Sino-American relations at a pivotal time in our shared history.

In this collection of essays written by the former head of the Library of Congress Chinese Collection, Chi Wang chronicles the modest beginnings of the Chinese Collection at the Library of Congress and his crusade to transform it into the largest collection and Chinese cultural presence outside Asia.For anyone who has ever wondered what goes on inside the marble walls of one of the country's oldest federal institutions, Wang relates an insider's account of the major milestones and changes to the administration of the Collection over the years. Readers will be surprised not only to learn about some of the rare and priceless books that have found their way to the Library of Congress but also by the candor with which Wang shares his story about serving under three different Librarians of Congress, each with a different mandate and mark they wanted to leave behind.Building a Better Chinese Collection for the Library of Congress has value as American library history but also serves as a useful introduction to Chinese historical archives and libraries. Select writings discuss publication and personnel exchanges with Chinese academic libraries, Chinese character encoding and library automation, and publishing activities in China.
