The area of associative content analysis and information retrieval is reviewed in this study. The available experimental evidence shows that none of the existing or proposed methodologies are guaranteed to improve retrieval performance in a replicable manner for document collections in different subject areas. The associative techniques are most valu- able for restricted environments covering narrow subject areas, or in iter...
