Abstract

The traditional notion of topical relevance has allowed much useful work to be done in the evaluation of retrieval systems, but has limitations for complete assessment of retrieval systems. While topical relevance can be effective in evaluating various indexing and retrieval approaches, it is ineffective for measuring the the impact that systems have on users. An alternative is to use a more situational definition of relevance, which takes account of the impact of the system on the user. Both types of relevance are examined from the standpoint of the medical domain, concluding that each have their appropriate use
