Dataset Card for MRREL Data

Dataset Description

Dataset Summary

The MRREL data is a component of the UMLS (Unified Medical Language System) Metathesaurus, available in the Rich Release Format (RRF). This dataset contains information about relationships between medical concepts and atoms, providing a detailed resource for understanding the interconnections within the UMLS Metathesaurus. It supports developers and researchers in comprehensively representing and utilizing medical terminology and their relationships.

Purpose

The MRREL dataset offers structured information on the relationships between medical concepts and atoms. This data is crucial for medical informatics applications, clinical decision support systems, and other health-related software solutions, aiding in the precise representation and understanding of the relationships among medical terms.

Column Descriptions

CUI1 (Concept Unique Identifier 1)

  • Description: A unique identifier assigned to the first concept in the relationship within the UMLS Metathesaurus.
  • Values: Alphanumeric strings, such as C0001175. Each value uniquely identifies a medical concept.

AUI1 (Atom Unique Identifier 1)

  • Description: A unique identifier for the first atom in the relationship, which is a specific occurrence of a string in a source vocabulary.
  • Values: Variable length field, typically 8 or 9 characters, such as A0019180. Each value uniquely identifies an atom within the dataset.

STYPE1 (Source Type 1)

  • Description: The name of the column in MRCONSO.RRF that contains the identifier used for the first element in the relationship, e.g., AUI, CODE, CUI, SCUI, SDUI.
  • Values: Alphanumeric strings indicating the source type, such as AUI, CODE, CUI, SCUI, SDUI.

REL (Relationship)

  • Description: The type of relationship of the second concept or atom to the first concept or atom.
  • Values: Alphanumeric strings indicating the relationship type, such as RN, RO, RQ, SY, RL, CHD, PAR, QB, QB2, QB3.

CUI2 (Concept Unique Identifier 2)

  • Description: A unique identifier assigned to the second concept in the relationship within the UMLS Metathesaurus.
  • Values: Alphanumeric strings, such as C0001175. Each value uniquely identifies a medical concept.

AUI2 (Atom Unique Identifier 2)

  • Description: A unique identifier for the second atom in the relationship, which is a specific occurrence of a string in a source vocabulary.
  • Values: Variable length field, typically 8 or 9 characters, such as A0019180. Each value uniquely identifies an atom within the dataset.

STYPE2 (Source Type 2)

  • Description: The name of the column in MRCONSO.RRF that contains the identifier used for the second element in the relationship, e.g., AUI, CODE, CUI, SCUI, SDUI.
  • Values: Alphanumeric strings indicating the source type, such as AUI, CODE, CUI, SCUI, SDUI.

RELA (Additional Relationship Label)

  • Description: An optional, more specific label for the relationship.
  • Values: Alphanumeric strings providing additional specificity for the relationship, such as isa, part_of, has_part, associated_with. There are 964 unique values.

RUI (Relationship Unique Identifier)

  • Description: A unique identifier for the relationship.
  • Values: Alphanumeric strings, such as R123456. Each value uniquely identifies a relationship within the dataset.

SL (Source of Relationship Labels)

  • Description: The source of the relationship labels.
  • Values: Alphanumeric strings indicating the source, such as MSH, SNOMEDCT_US, LNC, CSP.
