[i] This table lists the category name in the first column, the corresponding gene ontology code in the second column, and the PubMed query used to obtain abstracts in the final column. For the training dataset, the articles were obtained by using the query as listed in the table. Within a PubMed query the [MAJR] label specifies MeSH major headings, [MH] specified MeSH headings, [TI] specifies title words, and [DP] species publication data ranges. The test2000 and test2001 datasets were obtained by modification of the publication date limit to restrict articles to those published in 2000 and 2001, respectively. Titles were omitted from the test data sets. The table lists the number of articles obtained for each category for the training and test sets.
