Abstract
Relevance arises from relationships between user needs and documents/information. In the quest for relevant retrieval, some content-based relationships are best used initially to cast a net that emphasizes recall, while others, both content- and non-content-based, are best used subsequently as filtering devices to achieve better precision. Topical relevance, the primary factor in the initial retrieval operation, extends far beyond topic matching, as often assumed. Empirical studies demonstrate that topical relevance relationships are drawn from a broad but systematic inventory of semantic relationships.
