- Abstract
- Few studies have compared the interactive use of Boolean and natural language search systems. Studies the use of 3 retrieval systems by senior medical students searching on queries generated by actual physicians in a clinical setting. The searchers were randomized to search on 2 or 3 different retrieval systems: a Boolean system, a word-based natural language system, and a concept-based natural language system. Results showed no statistically significant differences in recall or precision among the 3 systems. Likewise, there is no user preference for any system over the other. The study revealed problems with traditional measures of retrieval evaluation when applied to the interactive search setting
