    Abstract
    This study develops evaluation indicators for a consortium of Korean institutional repositories called dCollection and validates the indicators against actual data from the participants of this consortium. The literature review reveals a conceptual framework for institutional repository (IR) evaluation with four categories and 19 items. In developing the initial framework, equal amounts of emphasis are put on the assessments of procedural achievement and actual performance to pinpoint the procedural weaknesses of each IR and to determine its customized solution. A Delphi method of three rounds with the help of IR librarians reveals a converging tendency pertaining to the measures of importance ascribed to the categories and items. Through a focus-group interview with middle- to top-level managers, 39 indicators derived from 19 items are identified as possessing relevancy, measurability, data availability, and differentiability. Validation of evaluation indicators employs actual evaluation data from 32 university IRs. Factor analysis shows a simpler structural pattern containing 12 factors than that of the structural pattern of the conceptual framework that contains 19 items. Correlation analysis using the factor scores identifies six key factors: Registration Rate, Archiving, Resource Allocation, System Performance, Multifunctionality, and Use Rate. The results from regression analyses suggest that two different approaches can be employed to promote the Use Rate factor. In the content-oriented approach, the Registration Rate factor is crucial while in the policy-oriented approach the Archiving factor assumes this role; however, the System Performance factor plays a mediating role for the key factors, thus forming a contingency for either approach.

    Abstract
    The design and implementation of an ontology-based Web retrieval (ONTOWEB) system is described; ONTOWEB allows the semantic search of the Web resources of international organizations such as the World Bank and the Organisation for Economic Co-operation and Development (OECD). A firm's knowledge management project is introduced first, followed by a description of the ONTOWEB system's design, implementation, and evaluation. The ONTOWEB system has two components: databases and an ontology-based search engine. The ontology-based search engine is a tool used to query the information that has been loaded into the database. Last, to evaluate the system, an experiment was conducted to compare the performance of the proposed system with that of Internet search engines in terms of relevance and search time. This study shows that ontologies can be used not only to improve precision, but also to reduce the search time. Because of the expense of annotating resources, the domains that contain the most valuable knowledge, such as the medical and the business sectors, are prime areas for future ontology applications.
