PROBLEM TO BE SOLVED: To navigate source contents and to identify desired features in the source contents and semantic source meta-data corresponding to the part of the source contents. SOLUTION: This navigation device is provided with an input interface for receiving the request of the desired features and a processor for generating a retrieval request, with which the desired feature on the semantic meta-data is designated, from the request and processing the retrieval request so as to identify the semantic source meta-data showing the desired feature. An output interface outputs an indication on the part of the source contents corresponding to the identified semantic source meta-data as the desired feature. Thus, an exact and effective technology is provided for finding out the specified feature in the source contents.
