Taking the indexing entry of CBMdisc as a gold standard, the key words of 256 articles in the 23 military medical journals are compared and analyzed. Four types of problems were summarized: 1) the problems of indexing quality; 2) error coordination of subject headings and subheadings; 3) adjectives and adverb s were used in free words indexing and some unpopular abbreviations were used in key words indexing; 4) the number of key words was generally not enough. In order to improve key words indexing, more attentions should be paid to article indexing, and the latest indexing reference books should be used as well. The standard procedures of indexing should be strictly followed so as to imprave the quality of the overall literature indexing. |
