Text Analysis - Automatic Categorization - Categorize list of items

From Q
Jump to navigation Jump to search

This QScript tTakes the selected Text variable and extracts categories from text data with a list-like format (i.e.: nouns separated by delimiters) by using the text variable in a List of items calculation. The algorithm will also attempt to analyse cases with text data that is not in this format, e.g. sentences, and correct misspellings.

Example

The example below shows a list categorization output for a survey question on which software respondents use for coding text data. The Categories section which is expanded shows a table of the categories on the left and the raw and transformed text on the right. Each category is distinguished by a unique shading, whereas replaced text is shaded in bright yellow. The Diagnostics section at the bottom (which is collapsed but can be expanded) shows diagnostic information for each processing step (which are also collapsed but can be expanded).
