<http://purl.org/dc/elements/1.1/description> """The RELD Core Scehma (http://reld.dice-research.org/schema#) provides classes and properties to describe the NLP sub task Relation Extraction. The schema models the relations, sentences, entities and related concepts. The schema represents the relation extraction in a standard manner where other relation extraction related datasets can easily maped to this schema. The schema is available on our webpage and we recommend the audience to visit our web page and explore our pre-print paper to further explore the schema.
The main class in this ontology is reld:Relation, which is the class of all relations available in different RE based datasets.
The data built using RELD schema its diagram all are available online. Apart from relation class RELD also maps sentences, subjects, objects, named entities and related properties.
