[Corpora-List] Create an ontology based on manual text annotations

Dear all,

I am looking for a tool for creating ontologies based on a manual annotation of texts. We want to easily annotate entities and relations between them. Example:

* “Big Mac” is manually annotated as a PRODUCT

* “McDonald’s” is manually annotated as a COMPANY

* “Big Mac” and “McDonald’s” are linked by a relation which is

manually annotated as IS_A_PROVIDER_OF.

It implies the following functionalities:

1. Definition of an ontology schema (PRODUCT, COMPANY, IS_A_PROVIDER_OF)

2. Entities with defined attributes

3. Relationships between predefined entity types (The relation

IS_A_PROVIDER_OF should only be possible between the entity types

COMPANY and PRODUCT.). The annotation of the relations should be

user-friendly, also across the whole document.

4. A plain text annotation tool

5. A way to export the ontology that has been created

I am wondering if such a tool exists and is available

Many thanks for your help

Best regards

Louis
