Capturing and Exploiting
Semantic Relationships for Information and
TRELLIS is an interactive environment that allows users to add their observations, opinions, and conclusions as they analyze information by making semantic annotations to documents and other on-line resources. This is in essence a knowledge acquisition problem, where the user is adding new knowledge to the system based on their expertise as they analyze information. The TRELLIS project is described in detail here .
TRELLIS includes a
vocabulary for semantic annotations of decisions and tradeoffs. The
initial version of this vocabulary is now available as a schema/ontology
in XMLS, RDFS, and DAML+OIL. TRELLIS allows users to extend this vocabulary
and its corresponding schemas.
People have used TRELLIS to annotate tradeoffs and decisions (e.g., travel), organizing materials (e.g., search results), analyzing disagreements and controversies on a topic (e.g., political debates), handling incomplete information (e.g., genealogy research), etc. TRELLIS generates these annotations in XML, RDF, and DAML+OIL according to the schemas and ontologies for the TRELLIS annotation vocabulary. Users can extend the vocabulary using the TRELLIS interface.
