Exploit HTML structure of the IAS document with
TableAnalyzer
9
TableAnalyzer ontology part

• add relationships between concepts, e.g.
• Entry Account has-a Sum Account
• Entry Account has-a Account Name
• create instances, e.g.
• the concept Entry Account has the
  instances1,050,001, 1,050,002, etc.

10
Resulting ontology

• number of concepts by OntoExtract 1500
• number of concepts extended by TableAnalyzer
  9
• (added relationships)

11
GUI Integration of TableAnalyzer concepts

• add dropdown list with TableAnalyzer concepts,
  e.g.
• user selects Entry Account
• types in the field account name Fixed
  Maturities
• Effect
• select Entry Account where account name like
  fixed maturities
• Go from Reference Retrieval to Fact
  Retrieval

• users reformulate a query on the average more
  than once
• users wish to find account numbers according to
  given criteria

SkiM Skills Management at Swiss Life

• Prototype in use ca.150 registered user
• User feedback influenced further development
  - available information categories - need for
  improved query functionality and effectiveness
  - smaller ontology for education, hierarchy for
  job functions deleted
• RDF annotation added to distinguish information
  categories
• Integration of RDFFerret

Use RDF annotations for more precise queries,
e.g. distinguish UML in the context of
skills from UML in the context of
projects-involved
Corresponding RQL queries as generated from user
input
Select P From Employee(P) . has-skillsS Where
SUML Select P From EmployeeP .

Main evaluation result

• high acceptance of underlying design concept
• better focusing query engine
• users find it difficult to browse the
  ontologies - problem of user interface? -
  problem of ontology structure?

23
Summary

• Two different case studies
• manually vs. automatically built ontology
• concept hierarchy vs. associative net

• Utilize RDF annotations to
• allow fact retrieval- specify context in which
  a query term is to be evaluated
