Book Description
Los metadatos o la necesidad de etiquetar, catalogar y describir información estructurada, de tal forma que los documentos digitales se puedan procesar, almacenar, conservar, recuperar e intercambiar a través de la World Wide Web, protagonizarán, sin duda, un nuevo paradigma en los sistemas y servicios de información del siglo xxi. Este tema ha despertado un gran interés y debate científico en la comunidad bibliotecaria internacional y en todo el sector emergente de los sistemas de información electrónica, debido a la evidencia de Internet como fuente, depósito y recurso de información, así como a las nuevas formas de registrar el conocimiento que conlleva la explosión de la información digital. Todos estos cambios han puesto en tela de juicio los métodos tradicionales de procesamiento de la información (catalogación, clasificación e indización), e imponen una redefinición estratégica del papel del gestor de la información ante la biblioteca digital.

Book Description
Esta obra se forma a partir de las reflexiones recogidas del Seminario de Investigación sobre Metadatos y el esfuerzo colectivo de distintos investigadores y especialistas cuyo marco de discusión fue analizar los aspectos conceptuales, teóricos y metodológicos sobre el uso de los metadatos desde una perspectiva multidisciplinaria. Desde que los metadatos aparecieron en la bibliotecología, se consideraron como referentes para la descripción de los recursos de información y los servicios que potencialmente se ofrecen a los usuarios. De ahí que su fin principal sea facilitar la identificación, localización, recuperación, manipulación y uso de los datos contenidos en los recursos de información. En este libro advertimos estos funcionamientos desde la perspectiva de la bibliotecología, los estudios de la información, y otras materias afines.

Book Description
Metadata research has emerged as a discipline cross-cutting many domains, focused on the provision of distributed descriptions (often called annotations) to Web resources or applications. Such associated descriptions are supposed to serve as a foundation for advanced services in many application areas, including search and location, personalization, federation of repositories and automated delivery of information. Indeed, the Semantic Web is in itself a concrete technological framework for ontology-based metadata. For example, Web-based social networking requires metadata describing people and their interrelations, and large databases with biological information use complex and detailed metadata schemas for more precise and informed search strategies.There is a wide diversity in the languages and idioms used for providing meta-descriptions, from simple structured text in metadata schemas to formal annotations using ontologies, and the technologies for storing, sharing and exploiting meta-descriptions are also diverse and evolve rapidly. In addition, there is a proliferation of schemas and standards related to metadata, resulting in a complex and moving technological landscape — hence, the need for specialized knowledge and skills in this area.The Handbook of Metadata, Semantics and Ontologies is intended as an authoritative reference for students, practitioners and researchers, serving as a roadmap for the variety of metadata schemas and ontologies available in a number of key domain areas, including culture, biology, education, healthcare, engineering and library science.

Book Description
This book begins with an introduction to fundamental issues related to digital preservation metadata before proceeding to in-depth coverage of issues concerning its practical use and implementation. It helps readers to understand which options need to be considered in specifying a digital preservation metadata profile to ensure it matches their individual content types, technical infrastructure, and organizational needs. Further, it provides practical guidance and examples, and raises important questions. It does not provide full-fledged implementation solutions, as such solutions can, by definition, only be specific to a given preservation context. As such, the book effectively bridges the gap between the formal specifications provided in a standard, such as the PREMIS Data Dictionary – a de-facto standard that defines the core metadata required by most preservation repositories – and specific implementations. Anybody who needs to manage digital assets in any form with the intent of preserving them for an indefinite period of time will find this book a valuable resource. The PREMIS Data Dictionary provides a data model consisting of basic entities (objects, agents, events and rights) and basic properties (called “semantic units”) that describe them. The key challenge addressed is that of determining which information one needs to keep, together with one’s digital assets, so that they can be understood and used in the long-term – in other words, exactly which metadata one needs. The book will greatly benefit beginners and current practitioners alike. It is equally targeted at digital preservation repository managers and metadata analysts who are responsible for digital preservation metadata, as it is at students in Library, Information and Archival Science degree programs or related fields. Further, it can be used at the conception stage of a digital preservation system or for self-auditing an existing system.

Book Description
Metadata play a fundamental role in both DLs and SDIs. Commonly defined as "structured data about data" or "data which describe attributes of a resource" or, more simply, "information about data", it is an essential requirement for locating and evaluating available data. Therefore, this book focuses on the study of different metadata aspects, which contribute to a more efficient use of DLs and SDIs. The three main issues addressed are: the management of nested collections of resources, the interoperability between metadata schemas, and the integration of information retrieval techniques to the discovery services of geographic data catalogs (contributing in this way to avoid metadata content heterogeneity).

Book Description
As the World Wide Web has emerged as a major research tool across all fields of study, the concept of metadata has become a crucial topic. Metadata, which can be broadly defined as "data about data," refers to the searchable definitions used to locate information. This issue is particularly relevant to searches on the Web, where metatags may determine the ease with which a particular Web site is located by searchers. This book defines this little-understood concept, explains its importance and potential uses in the networked environment, and describes existing metadata standards in the field of cultural heritage information.

Book Description
Improvements in network bandwidth along with dramatic drops in digital storage and processing costs have resulted in the explosive growth of multimedia (combinations of text, image, audio, and video) resources on the Internet and in digital repositories. A suite of computer technologies delivering speech, image, and natural language understanding can automatically derive descriptive metadata for such resources. Difficulties for end users ensue, however, with the tremendous volume and varying quality of automated metadata for multimedia information systems. This lecture surveys automatic metadata creation methods for dealing with multimedia information resources, using broadcast news, documentaries, and oral histories as examples. Strategies for improving the utility of such metadata are discussed, including computationally intensive approaches, leveraging multimodal redundancy, folding in context, and leaving precision-recall tradeoffs under user control. Interfaces building from automatically generated metadata are presented, illustrating the use of video surrogates in multimedia information systems. Traditional information retrieval evaluation is discussed through the annual National Institute of Standards and Technology TRECVID forum, with experiments on exploratory search extending the discussion beyond fact-finding to broader, longer term search activities of learning, analysis, synthesis, and discovery. Table of Contents: Evolution of Multimedia Information Systems: 1990-2008 / Survey of Automatic Metadata Creation Methods / Refinement of Automatic Metadata / Multimedia Surrogates / End-User Utility for Metadata and Surrogates: Effectiveness, Efficiency, and Satisfaction

Book Description
As the integration of statistical data collected in various subject matter domains becomes more and more important in several socio-economic etc. investigation areas the management of so-called metadata – a formal digital processing of information about data – gains tremendously increasing relevance. Unlike current information technologies (e.g., database systems, computer networks, ...) facilitating merely the technical side of data collation, a coherent integration of empirical data still remains cumbersome, and thus rather costly, very often because of a lack of powerful semantic data models capturing the very meaning and structure of statistical data sets. Recognizing this deficiency, "Metadata Management" proposes a general framework for the computer-aided integration and harmonization of distributed heterogeneous statistical data sources, aiming at a truly comprehensive statistical meta-information system.
