| Abstract: | An experiment was performed to evaluate the relative effectiveness of a top-down approach and bottom-up approach to structuring multiattributed hierarchies. It was hypothesized that the top-down approach would result in both (1) a more accurate hierarchy and (2) a deeper hierarchy than the bottom-up approach. Although the latter hypothesis was supported, the former was not. Implications for further research are discussed. |
