Research questions
  • Which insect have been found at specific sites?
    How were these samples dated?
  • What ecological landscapes do these insects
    represent? How rare are they?
  • Where has a particular insect been found? And how
    were they dated? Through which types of
    investigation (archaeology/geology) were they
    found?

9
Faceted browsing and queries
  • Facet order is arbitrary
  • Facets can connect to multiple entities
  • A facet is a result and a filter
  • A selection in a facet is filtering facets to the
    right.
  • Queries will populate affected facet based on
    filter in other facets
  • Queries need to connect to multiple tables
  • Query combinations are more than possible
    permutation of facets

10
HUMlab faceted browsing system
  • Runs over normalized, relational database models.
  • The table structure need to represent the
    entities and the types of relationships that
    exist.
  • The abstraction layer enables dynamic query
    building depending on the facets arrangement
