Extracts a table containing one row per unique keyword found in the database, where a keyword is unique by the keyword itself and the type of keyword it is (author or ISI). The resulting table contains the following columns:
- keyword: The keyword.
- type: The type of the keyword. Keywords are either provided by the authors of the papers, or generated by ISI automatically. See Load ISI File Into Database/KEYWORD for more details.
- occurrences_in_dataset: The number of times this unique keyword occurs in the dataset. Keywords from authors are counted separately from keywords generated by ISI.
The specific query run by the tool can be found in the source code.
