Principles

We follow the subject-predicate-object logic when defining relations between entities, so that the relations in the text accurately reflect the underlying structure. Specific constraints on these relations allow us to link related entities correctly. These constraints reorder the relation choices in INCEpTION based on the context of the annotation: appropriate relations are displayed first, highlighted in bold, and allow for a more efficient annotation process. For example, an entity of type quality, which can be combined with several entities (e.g., person), should only use has characteristic as a relation, so that the triple person quality applies.

Dos

To ensure consistency in the annotation process, the following principles should be adhered to when annotating entities:

  1. Annotate explicit mentions only. Only explicitly mentioned entities and relations are annotated; we do not infer entities or relations.
  2. Use specified tags only. Only entities and relations from the annotation guidelines are employed; we do not create additional entities or relations.
  3. Annotate persons individually. Each person in the text should be annotated individually.
  4. Annotate repeated mentions. Repeated mentions of the same entity, also in consecutive sentences, should be tagged each time.
Don'ts

Certain elements within the text should not be annotated. The following entities are excluded:

  1. Exclude bibliographic information. Bibliographic information is excluded from annotations.
  2. Exclude physical metadata. Tags are not applied to institutions holding the work of art or other physical metadata such as its location.
  3. Exclude formatting elements. Headings, lists, and bullet points are not annotated unless they contain relevant content about the work of art.
