Abstract

Choi and Rasmussen collect queries to the Library of Congress's American Memory photo archive from 48 scholars in American History by way of interviews and pre and post search questionnaires. Their interest is in the types of information need common in the visual domain, and the categories of terms most often used or indicated as appropriate for the description of image contents. Each search resulted in the provision of 20 items for evaluation by the searcher. Terms in queries and acceptable retrievals were categorized by a who, what, when, where faceted classification and queries into four needs categories; specific, general, abstract, and subjective. Two out of three analysts assigned all 38 requests into the same one of the four categories and in 19 cases all three agreed. General/nameable needs accounted for 60.5%, specific needs 26.3%, 7.9% for general/abstract, and 5.3% for subjective needs. The facet analysis indicated most content was of the form person/thing or event/condition limited by geography or time.
