This one-day course will review the advantages and examples of faceted hierarchical classification in taxonomies, then demonstrate how the addition of synonyms, related topics and shared attributes can create a "hybrid classification system" to power improved information retrieval and delivery.
- deeper understanding of content classification beyond simple taxonomies;
- knowledge of the benefits of a thesaurus to define synonyms and an ontology to define relationships;
- awareness of "contextual keywords," from relevant documents or a user-contributed "folksonomy;"
- practical experience in extending taxonomy topics with this additional metadata;
- appreciation of how hybrid classification supports the semantic web and linked data;
- introduction to relevant UK and international standards and appropriate software tools.
- review benefits of taxonomy structure, then demonstrate how to extend it with synonyms, related topics and shared attributes, using the structures of a thesaurus and an ontology;
- introduce the linking of synonym rings to create "semantic nets" to discover information;
- discuss how to use subject experts, automated content clustering and social networks to define related topics and contextual keywords;
- assess shared attributes to establish and structure relationships;
- conduct hands-on exercise to extend taxonomy with this related metadata;
- review tools for managing and displaying descriptive metadata, and examine relevant UK and international standards for marking up content;
- show how combining the components of a controlled vocabulary can improve precision and recall when searching for or delivering information.
