Review and enrich a dataset

Once you have uploaded a dataset into your project, you can open it to:

  • Explore and summarize its data and columns.
  • Manually add metadata that explains the data in each column.
  • Automatically enrich metadata using documents in your dataset or without additional context.

Review a dataset

To get an understanding of your data, you can open a dataset and review its columns and a selection of its rows. A dataset resource previews up to 100 rows of data.

Open a dataset

  • Perform one of the following actions:

    • In the Resources panel, click the name of the dataset.
    • On a Dataset node in the workflow graph, click Open.
View the raw data in a dataset
  • Click Data in the navigation list on the right.
Download a dataset
  • Next to the dataset name, click Menu > Download.

Enrich a dataset

If your dataset lacks descriptive details about what each column contains, you can use Terarium's dataset enrichment capability to complete the:

  • Units: What the column measures (dates, cases, people) or contains (text).
  • Descriptions: A short plain language explanation of the column's contents.
  • Concepts: Epidemiological concepts that relate to the data in the column. Helpful in mapping data to model variables.
  • Distributions of values

Terarium's enrichment service uses an AI language model to generate column details based on either:

  • Contextual clues in the contents of a document in your project.
  • The column headers in the dataset. In this case, the language model attempts to define the columns as if they relate to a general epidemiological context.
Note
  • Curating concepts improves structural comparison and alignment of models and data.
  • If Terarium can't determine what a column represents, it fills out the description to summarize distribution of values it contains.
