Title: Determining the subject content of still and moving image documents for storage and retrieval: An experimental investigation

Abstract: Subject access to the mass of visual documentation accumulated in this century is inadequate. Techniques used with text materials have not been adapted successfully for use with visual materials. Different levels of terminology are available, and the model widely used with art collections considers pre-iconographical, iconographical, and iconological description.

Evidence was sought which would suggest appropriate ways to index non-art pictures, particularly film and video clips. Two videocassettes were compiled, each containing the same 44 ten-second clips of everyday objects and events. Each videocassette contained a mix of still and moving images, and of simple and complex images; the shots on both tapes were in the same order. However, the still images on one tape were moving on the other, and vice versa. Participants were classified as to visual orientation and level of experience. They screened one or the other tape, and for each shot, wrote descriptors under which they would file the shots in some hypothetical information system.

Analysis included the number of terms each participant supplied for each shot, and the levels of agreement among participants on the most frequently named terms. Although statistically significant differences were found in the numbers of terms supplied, it is doubtful whether these differences have practical significance. Significant differences were also found in the levels of agreement on the most popular terms. There was more agreement on terms for the simple shots than for the complex shots using some measures, as well as on terms supplied by people who work with images than on those supplied by students. Differences in levels of agreement due to visual orientation or to motility of the shots were not found.

Participants overwhelmingly supplied basic-level terminology, naming objects and events prominent in the images. Patterns in terminology found in previous research with other types of materials were echoed in the responses of the participants. A few terms are named often, and the great majority of the terms are named only once.
