Deep Web Query Interface Understanding and Integration

摘要: There are millions of searchable data sources on the Web and to a large extent their contents can only be reached through own query interfaces. is an enormous interest in making these easily accessible. primarily two general approaches achieve this objective. The first surface from deep add index regular search engines. second integrate searching capabilities support integrated access them. In book, we introduce state-of-the-art techniques for extracting, understanding, integrating interfaces sources. These critical producing interface each domain. serves as mediator all concerned While integration relevant approach, extraction understanding both exploration approaches. This book aims provide in-depth comprehensive coverage key technologies needed create high quality automatically. following technical issues discussed detail book: modeling, extraction, clustering, matching, attribute integration, integration.
