QUALITY EVALUATION OF DIGITAL LIBRARIES AT WEB ENVIRONMENT
Keywords:
Quality of the digital library, usability services, model DELOSAbstract
The article considers the problem of assessing the quality of digital libraries. The basis for a set of criteria to assess the DL is modeled DELOS DLRM. For most quality parameters proposed metrics that allow a quantitative assessment. Selection metrics has been proposed based on the fact that EB operates in the web environment. This approach is new in relation DELOS DLRM, since this model does not focus, on the operation of digital libraries in the web environment. The paper presents a formal model for usability evaluation based reflection of user behavior on the site through a change of the system states. The proposed technique allows ongoing assessment of more independently, using the statistics. Also proposed metrics to assess security settings DL in the web environment.References
