Searching for information in large rather unstructured real-world data sets is a dicult task, because the user expects immediate responses as well as high-quality search results. Today, existing search engines, like Google, apply a keyword-based search, which is handled by indexed-based lookup and subsequent ranking algorithms. This kind of search is able(More)
Nanoplasmonic excitations as generated by few-cycle laser pulses on metal nanostructures undergo ultrafast dynamics with timescales as short as a few hundred attoseconds (1 as = 10(-18) s). So far, the spatiotemporal dynamics of optical fields localized on the nanoscale (nanoplasmonic field) have been hidden from direct access in the real space and time(More)
Konzepte aus der Domäne Tourismus beschränkt ist (siehe Abbildung 1). Die Wurzel der Ontologie ist das Konzept " Object ". Darunter wurden die vier Hauptkonzepte " TouristicObject " , " Person " , " Event " und " Media " definiert, von denen alle weiteren speziali-sierten Unterkonzepte abgeleitet werden.
