As metadata become of increasing importance to the Web, we will need to start managing such metadata. We argue that there is a strong need for metadata management. We introduce the Spectacle Workbench for verifying semi-structured information and show how it can be used to validate, aggregate and visualize the metadata of an existing information system. We conclude that the possibility to verify and aggregate metadata is an added value with respect to contents-based access to information and that it is possible to generate it on the basis of Web contents.

Contribution to a special issue on image access. Keyword search of multimedia collections lacks precision, and automatic parsing of unrestricted natural language annotations lacks accuracy. Proposes a structure for natural language descriptions of the semantic content of visual materials that requires descriptions to be (modified) keywords, phrases or simple sentences, with components that are grammatical relations common to many languages. This structure makes it easy to implement a collection's descriptions as a relational database, enabling efficient search via the application of well developed database indexing methods. Description components may be elements from external resources (thesaurus, ontology, database or knowledge base). This provides a rich superstructure for the meaningful retrieval of images by their semantic contents. (AU) |
