Annotations

What`s the differenct between a link and a relationship?

Links are used to gather scattered information in a document, words or groups of words which address the same information but in several places of the document. Links are used to concatenate information in a model by removing unnecessary tokens that separate them.

Example : In a transcription of a telephone conversation, the links will be very useful to remove the elements which break up the fluidity of the speech of an interlocutor (the apostrophes, the breaks).

Relationships focus on the semantic relationships between an 'owner' attribute and its associated 'target' entities. More precise than links, relationships underline a hierarchy in information, between a central concept (owner) and its relative information (target).

Example : In a product specification sheet, the relationships will allow a central element of the product (its weight) to be associated with a numeral entity (a mass in kg).
