Abstrakt

During the last decade, the emphasis has been on finding relevant documents or content, an objective which most of today's search and browsing techniques address. During the next decade, the emphasis will shift from documents and entities to relationships - that of discovering or validating contextually relevant, meaningful and possibly complex relationships amongst the entities that documents mention and describe. This also is likely to be the next area of focus for the Semantic Web community after it makes progress in addressing the current areas of emphasis on ontology representation, semantic metadata extraction for automatic annotation, query processing and making inference.

Relationships are fundamental to semantics - they associate meanings to words, terms and entities. Semantic Web intends to associate annotations (i.e., metadata) with all Web-accessible resources such that programs can associate "meaning with data" to interpret them, and to process (access, invoke, utilize, and analyse) them automatically, resulting in higher scalability and better productivity. More comprehensive set of relationships that may be based on information extraction, external and prior knowledge and user-defined computations is looked for. Some software tools for semantic analysis and usage of selected IT tools in the scientific library context are considered in this presentation.
