Frequency Analysis


Utilized iteratively throughout the life cycle of a project as search criteria are modified, frequency analysis may be used to evaluate the effectiveness of the initial search criteria. The search terms are tested to determine whether they effectively discriminate between potentially relevant and clearly non-relevant data. Frequency analysis is a reality check on the search results versus the overall collection size and the reasonably expected proportion of relevant results. It does not address the recall or completeness of relevant items out of the collection.
