# 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`. |
|
|
|
