Cross Source Links

Dimensions data provides ability to retrieve related entities, such as supporting grants to publications.

The diagram above shows the ID fields that can be used to retrieve related source entities. ID fields provide relations between:

1. Publications ↔ Publications via references_ids

2. Publications ↔ Grants via supporting_grant_ids

3. Publications ↔ Researchers via researchers

4. Patents ↔ Patents via reference_ids and cited_by_ids

5. Patents ↔ Grants via associated_grant_ids

6. Patents ↔ Publications via publication_ids

7. Grants ↔ Publications via resulting_publication_ids

8. Grants ↔ Researchers via researchers

9. Clinical Trials ↔ Grants via associated_grant_ids

10. Clinical Trials ↔ Publications via publication_ids

11. Clinical Trials ↔ Researchers via researchers

12. Policy Documents ↔ Publications via publication_ids

User can retrieve related entities using two steps. First, retrieve the related IDs, such as for example, retrieving supporting grant IDs for publication:

search publications where id = "pub.1103155411"
return publications[supporting_grant_ids]

Then, make a follow up request, using retrieved supporting_grant_ids, to request the actual grant information:

search grants where id in ["grant.7025938", "grant.2686578", "grant.2683072", "grant.2491045"]
return grants

Similarly, other sources can be linked together, using provided ID fields.

In the next paragraphs we provide more specific examples for each of the cross source links.

Warning

The syntax search in investigators must not be confused with search where researchers.id=... Eg the query search grants in investigators for "\"C Iftode\"" return grants searches across all the named investigators in grants, irrespectively of whether they have been disambiguated and hence given a Dimensions researcher ID.

The same applies to the query search publications in authors for "\"C Iftode\"" return publications (as opposed to search publications where researchers.id=..).

Furthermore, the grants source provides another field investigator_details which is used to group additional metadata associated to investigators, eg their role in a grant, such as PI, Co-PI etc..
