Metadata and semantic research

Meer over het boek

Theoretical research results and proposals include a Dublin Core application profile for musical resources and a usage-oriented approach to topic maps. A semantic method for managing software engineering processes is discussed, along with clarifications on the semantics of relationships between learning objects. The framework for automating indexing algorithm selection and an empirical analysis of errors in human-generated metadata are also presented. Additional topics cover educational metadata analysis, a fine-grained metric system for metadata completeness, and unified semantic search of data and services. Case studies highlight a semantic web-based system for context metadata management, an XML pipeline architecture for bibliographic metadata, and DataStaR, which bridges XML and OWL for science metadata management. The structured metadata representation of complex narrative information and a semantic web framework for knowledge management in chronic disease healthcare are explored. The enrichment of the breast cancer database through ontology and an ontology-based approach to information security are evaluated, alongside the reusability of learning objects in open repositories based on metadata. Special tracks focus on agriculture, food, and environment, addressing quality assurance in agricultural learning repositories and ontology design for agri-informatics.
