홈페이지 · 논문 1편

A curated evaluation dataset for end-to-end Relation Extraction of relationships between organisms and natural-products. Details about the manual annotation: * For Chemicals: - The chemical labels are annotated as they appear in the abstract. - In abstracts, singular chemicals and classes of chemicals produced by a specific organism were distinguished. - The "type" attribute {“chemical”, “class”} is used to indicate the nature of the mentioned name. - A "class" attribute for chemical entities has also been included if class information is present in the abstract. - A Wikidata and PubChem identifiers were assigned to chemicals and classes when available. * For Organisms: - The organism labels are annotated as they appear in the abstract. - If in an abstract, the genus name was mention first, e.g. "Plakinastrella sp." and then the specie name e.g "Plakinastrella clathrata" is precise, then only the specie name is used. - A Wikidata identifier was assigned to all organisms. - In some abstracts, only the genus name is mentioned. * For Relations: - Only the relations explicitly mentioned in the abstract are reported in the output labels. - Relations are reported in their order of appearance in the abstract.
