The document discusses challenges with digital libraries and semantic support. It notes that human information processing is limited and computers do not understand natural language queries. Semantic support adds metadata to information to help humans and computers work together by giving meaning to data. However, communication between digital libraries remains a challenge. While some projects have created ontologies and cross-concordances, researchers often prefer to add their own tags due to difficulties making comprehensive ontologies for research data content. The literature on these topics is very technical and may not effectively communicate with scholars.
