Publication ontologies

In the same manner as solutions proposed for annotating and searching for information, the publication system is also founded on concepts drawn from the semantic web. The data manipulated by the transformation engine are made up solely of knowledge. First, it receives knowledge relative to the base elements of a publication, applies behaviors to them and generates knowledge relevant to the final product (website). The specification of source and target elements for this chain is performed as:

  • 1) a publication ontology stricto sensu and
  • 2) a final product ontology.

The publication ontology

The publication ontology is based on the core ontology that defines the main principles of an author publication, namely:

  • - The topic: a generic concept that designates the central element of a publication to which audiovisual contents are added. It can be stated differently as a function of the chosen publication genre. For example, it is given as a rubric and article in the lexical video, as a sequence in the narrative process, etc.;
  • - The audiovisual document (content): a concept taken from the description ontology that designates all audiovisual resources able to contribute to the illustration of the topics. These can be different types of resources: text, image (whole image, part of an image), video (whole video, video extract, segment) and sound (whole, sound segment);
  • - The corpus: a concept also taken from the description ontology that designates all possible groupings of audiovisual documents (see the previous section);
  • - The rhetorical relationships that can be used in any publication genre to propose a rhetorical exploration of the topics.

The publication ontology always depends on the publication genre and extends the underlying core ontology by defining elements that are particular to it. For example, the lexical video’s ontology extends the class “topic” to define two subclasses: “rubric” and “article”. The knowledge graph editor presented in section 4.3 is used by the author to create publication graphs in accordance with this ontology. These define and compare the base elements (topics, resources, corpuses, rhetorical relationships) of a given publication.
