Knowledge Discovery in Spatial Cartographic Information Retrieval.
Peer reviewed Peer reviewed
Yu, Lixin – Library Trends, 1999
Describes a prototype system--GeoMatch--that allows users to interactively define geographic areas of interest on a background map and to define, qualitatively or quantitatively, the relationship between the user-defined area and the map coverage. The knowledge discovery in database (KDD) factor is analyzed in the retrieval process. The MARC…

Mental Models Theory and Search Outcome in a Bibliographic Retrieval System.
Peer reviewed Peer reviewed
Dimitroff, Alexandra – Library and Information Science Research, 1992
A study investigated the relationship between the completeness of end users' mental models of an online system and their ability to use the system effectively. Although all of the study subjects were relatively successful, those with more complete mental models tended to have better search results than subjects with incomplete or poor mental…
