Cortext Epic Epoch

Context

  • Epic Epoch is a simple script for tracking dramatic changes in the composition of a field over time. It acts in three steps:
    • First, the N most frequently occurring entities are selected at each time period
    • A frequency timeline is built for each of the selected terms
    • A bump graph shows the evolution of frequency and ranking through time

Steps

  1. Login into https://rcf.risis.io.

  2. Create a project.

  3. Import the scenario ‘Cortext Epic Epoch’ into the project.

  4. Configure the project filling the inputs: cortext-epic-epoch-scenario.png

    • Dataset id: Select a dataset that you have previously uploaded in this project.
    • File id: Select a file from the dataset you have seleted in the previous field.

  5. When all the required fields are filled, you can click on the button in the top right ‘Run this scenario’.

  6. After the scenario execution is finished, check in the Outputs of the project for the new files produced (a bumpy graph and a csv file).
