Today, a multitude of information is available online. However, finding suitable information for a particular purpose is increasingly problematic. Recent work has indicated that faceted metadata can enable efficient annotation and retrieval of web based information. Semantic Web technologies provide different approaches to create and encode the faceted metadata. They make it possible to explicitly represent the background and meaning of web resources in a way that enables, for both humans and machines, the sharing of web-based information. This thesis presents the design and implementation of a system using these technologies. The system can enable the user to dynamically annotate the semantics of web-based data sources and retrieve information of interest. This thesis will present the example of a culinary recipe application domain. To avoid empty or nearly-empty result sets, a similarity analysis is introduced for organizing result sets based on semantic distances. A usability study was conducted to evaluate the system with a sample recipe collection. The study found that the interface with facet space cues was useful for browsing and annotating the data collection
