A relation between information objects and any Entity (including information objects). It can be used to talk about e.g. entities are references of proper nouns: the proper noun 'Leonardo da Vinci' isAbout the Person Leonardo da Vinci; as well as to talk about sets of entities that can be described by a common noun: the common noun 'person' isAbout the set of all persons in a domain of discourse, which can be represented in DOLCE-Ultralite as an individual of the class: Collection . The isAbout relation is reflexive (not expressible in OWL1.0), because information objects are also about themselves.

  • A relation between an information object and an Entity (including information objects). It can be used to talk about entities that are references of proper nouns: the proper noun 'Leonardo da Vinci' isAbout the Person Leonardo da Vinci; as well as to talk about sets of entities that can be described by a common noun: the common noun 'person' isAbout the set of all persons in a domain of discourse, which can be represented in DOLCE-Ultralite as an individual of the class: dul:Collection. A specific sentence may use common nouns with either a singular or plural reference, or it can even refer to all possible references (e.g. in a lexicographic definition): all those uses are kinds of aboutness. The isAbout relation is sometimes considered as reflexive, however this is semiotically inaccurate, because information can be about itself ('de dicto' usage, as in 'John is four character long'), but it is typically about something else ('de re' usage, as in 'John loves Mary'). If a reflexivity exists in general, it rather concerns its realisation, which is always associated with an event, e.g. an utterance, which makes the information denoting itself, besides its aboutness. This is implemented in DUL with the dul:realizesSelfInformation property, which is used with local reflexivity in the dul:InformationRealization class.
