Journal Descriptor Indexing

JDI (Journal Descriptor Indexing) uses statistical associations between the words in a training set of MEDLINE citations and a small set of 121 MeSH terms, known as JDs (journal descriptors) that index the approximately 5212 MEDLINE journals (1,999,012 MEDLINE records) per se in terms of biomedical disciplines. This JDI program along with MedLineTokenizer are used to indexing MedLine records on:

• Text: titles, abstracts, combination of titles and abstracts, or any phrase
• MeSHs: Starred main headings and subheadings
• Both: combinations of phrase and MeSHs
