Knowledge representation requirements in the area of OM conceptual information retrieval
Distinguish between document models and indexing ontologies
- for document models additional requirements like order of chapters, concepts as attribute fillers, specific links in hypertexts, „higher-order“ expressiveness for complex content descriptions
For indexing ontologies: some basic object-centered modeling formalism: concepts, attributes, instances
Some link to thesaurus information
Possibilities to freely define other relationships equipped with special inference mechanisms (domain and task specific)
Maybe later: special procedures for vague relationships: „has-to-do-with“
Maybe later: a clearer understanding of indexes and the „is-about“ relation
Maybe later: uncertainty and vagueness
