Query: Mapping knowledge with ontologies: the case of obesity   Scientometric techniques have been remarkably successful at mapping science
but they face important difficulties when mapping research for societal
problems possibly because they they are derived only from scientific documents
and thus do not rely on non-academic expert knowledge. Here we aim to explore
how ontologies can be used in science mapping, thus enriching current
algorithmic techniques with systematic domain expert knowledge. This study
introduces the methodology behind the construction of an ontology and tests
potential uses in science mapping. We use obesity as a topic of case study.
