Other Requirements: Ontology for a radio station
a) Sketch a normalised ontology for use by a radio station which covers the items listed below and provides sufficient concepts to answer the questions in part b). (10 marks)
Indicate the hierarchies for both concepts (classes and individuals) and properties (roles).
For concepts, indicate clearly which are classes and which are individuals. For roles, indicate any properties - symmetric, unique, or transitive. Not any ambiguities. Note also key design decisions to 'normalise' the ontology.
To save space. Assume all primitives are disjoint.
You may draw the hierarchies either as diagrams out in outline style. There is no need to use OWL syntax.
Items to be represented: Programmes, Presenters, Pop Music, Soap Opera, Albums,
News Bulletins, DJs, Rock Music, Time slots, Singles, Actors, Songs, Producers, Chat shows, CDs, The music library, Radio Stations, Classical music.
b) Define classes using your ontology for the items i) - v) below or explain why they cannot be expressed in OWL. Use owl abstract syntax (or a reasonable approximation). Be sure to distinguish someValuesFrom from allValuesFrom.
There may be some cases that cannot be represented in OWL form some reason or another. If so, indicate this and explain why.
If the definition in English is ambiguous, paraphrase it so it is unambiguous and then express the disambiguated notion in OWL.
i) Newsreader
ii) Programme directed by a woman
iii) Programme directed by its producer
iv) Classical music station
v) Programmes which have musical content but not classical music content.
