Past Usage:\N \N The hierarchical decision model, from which this dataset is\N derived, was first presented in \N \N M. Olave, V. Rajkovic, M. Bohanec: An application for admission in\N public school systems. In (I. Th. M. Snellen and W. B. H. J. van de\N Donk and J.-P. Baquiast, editors) Expert Systems in Public\N Administration, pages 145-160. Elsevier Science Publishers (North\N Holland)}, 1989.\N \N Within machine-learning, this dataset was used for the evaluation\N of HINT (Hierarchy INduction Tool), which was proved to be able to\N completely reconstruct the original hierarchical model. This,\N together with a comparison with C4.5, is presented in\N \N B. Zupan, M. Bohanec, I. Bratko, J. Demsar: Machine learning by\N function decomposition. ICML-97, Nashville, TN. 1997 (to appear)\N \N 4. Relevant Information Paragraph:\N \N Nursery Database was derived from a hierarchical decision model\N originally developed to rank applications for nursery schools. It\N was used during several years in 1980's when there was excessive\N enrollment to these schools in Ljubljana, Slovenia, and the\N rejected applications frequently needed an objective\N explanation. The final decision depended on three subproblems:\N occupation of parents and child's nursery, family structure and\N financial standing, and social and health picture of the family.\N The model was developed within expert system shell for decision\N making DEX (M. Bohanec, V. Rajkovic: Expert system for decision\N making. Sistemica 1(1), pp. 145-157, 1990.).\N \N The hierarchical model ranks nursery-school applications according\N to the following concept structure:\N \N NURSERY Evaluation of applications for nursery schools\N .
