Catalog of unique subj_terms assigned to IEAs

Catalog of unique subj_terms assigned by Stata code

As noted above, our Stata code leads to many IEAs having subj_terms and subj_codes variables that contain multiple Keywords and multiple Subject categories. To simplify the presentation in the present article, the IEADB used Stata code to assess each IEA’s set of subj_codes (with potentially multiple subjects) and assign that IEA a subj_code (single subject) corresponding to the highest-ranked subject in our hierarchy of eight subject codes (see above). That Stata code assigned 458 unique subj_term combinations to 52 unique subj_codes, which were then assigned one of our eight subject codes. Those assignments are documented below.

subj_terms (words found in title of IEA)

subj_codes (allows for multiple subjects)
