	abstract =	{We describe psychophysical experiments conducted to study
	PicHunter, a content-based image retrieval (CBIR) system. Experiment 1
	studies the importance of using (a) semantic information, (2) memory of
	earlier input and (3) relative, rather than absolute, judgements of
	image similarity.  The target testing paradigm is used in which a user
	must search for an image identical to a target. We find that the best
	performance comes from a version of PicHunter that uses only semantic
	cues, with memory and relative similarity judgements. Second best is
	use of both pictorial and semantic cues, with memory and relative
	similarity judgements. Most reports of CBIR systems provide only
	qualitative measures of performance based on how similar retrieved
	images are to a target. Experiment 2 puts PicHunter into this context
	with a more rigorous test. We first establish a baseline for our
	database by measuring the time required to find an image that is
	similar to a target when the images are presented in random order.
	Although PicHunter's performance is measurably better than this, the
	test is weak because even random presentation of images yields
	reasonably short search times. This casts doubt on the strength of
	results given in other reports where no baseline is established.},
