摘要:
In the networked environment,literature information has the characteristics of mass quantity,rapid growth and continuous emergence of new words.Indexing is an effective measure and an important part of information resource organization.The quality and efficiency of indexing directly affect the quality and speed of information organization.The authors carry out a quantitative comparison among three indexing models:controlled indexing,free indexing and automatic indexing,using consistency,specificity,exhaustivity and amount of common words.Then they conclude that automatic indexing is better than free indexing and controlled indexmg.
