  1. Import the data in your favourite format.

  2. To semplify the process, name the column containing the text as "text".

  3. If you don't have it, create a column "id" to have an identifier of the documents.

  4. With the first column filter, keep only the columns you need for scoring, "text" and "id" if you used the suggested names.

Create the dictionary using these instructions:

  1. Name the column with the terms of your dictionaries as "term".

  2. You can have at the same time terms with and without a wildcard.

  3. The second column should be the name of your construct that you want to measure. For example "positive".

  4. For each term linked to the reference construct, enter 1 in the cell, 0 otherwise.

  5. You can have multiple columns at the same time, each referring to a construct. Use coding with 1 or 0 to indicate whether the term belongs to the construct of that column or not.

EXTRA1: you can run the Verifier metanode to check for errors in the dictionary list.
