  We present Populous, a tool for gathering content with which to populate an
ontology. Domain experts need to add content, that is often repetitive in its
form, but without having to tackle the underlying ontological representation.
Populous presents users with a table based form in which columns are
constrained to take values from particular ontologies; the user can select a
concept from an ontology via its meaningful label to give a value for a given
entity attribute. Populated tables are mapped to patterns that can then be used
to automatically generate the ontology's content. Populous's contribution is in
the knowledge gathering stage of ontology development. It separates knowledge
gathering from the conceptualisation and also separates the user from the
standard ontology authoring environments. As a result, Populous can allow
knowledge to be gathered in a straight-forward manner that can then be used to
do mass production of ontology content.
