Abstract:
|
Team sports commentaries call for techniques that are able to select content and generate wordings to reflect
the affinity of the targeted reader for one of the teams. The existing works tend to have in common that they
either start from knowledge sources of limited size to whose structures then different ways of realization
are explicitly assigned, or they work directly with linguistic corpora, without the use of a deep knowledge
source. With the increasing availability of large-scale ontologies this is no longer satisfactory: techniques
are needed that are applicable to general purpose ontologies, but which still take user preferences into
account. We take the best of both worlds in that we use a two-layer ontology. The first layer is composed of
raw domain data modelled in an application-independent base OWL ontology. The second layer contains a
rich perspective generation-motivated domain communication knowledge ontology, inferred from the base
ontology. The two-layer ontology allows us to take into account user perspective-oriented criteria at different
stages of generation to generate perspective-oriented commentaries. We show how content selection, discourse
structuring, information structure determination, and lexicalization are driven by these criteria and
how stage after stage a truly user perspective-tailored summary is generated. The viability of our proposal
has been evaluated for the generation of football match summaries of the First Spanish Football League.
The reported outcome of the evaluation demonstrates that we are on the right track. |
