where Se is a semantic enrichment part of FVe that
represents a set of neighbourhood entities and
properties in an ontology O of a domain d. Le is a
linguistic enrichment of an entity that is a set of
terms (from document collection D of a particular
domain d) with a significant proximity to an entity
and its semantic neighbourhood. A parent entity of
a class is defined to be its super-class, while a
parent of an individual is the class of which the
individual is an instance or part. A child entity of a
class is defined to be its sub-class or individual, the
latter if it does not have a sub-class. Finally, other
neighbouring entities are any other related entities.
