The requirement of Allen operators for complete temporal knowledge goes against the monotonic knowledge generation sequence, which is witnessed in observation driven fields like stratigraphy. In such cases, incomplete temporal information yields a disjunctive ...

Anfrageverarbeitung und kollaborative verteilte Arbeit in Umgebungen mit unzuverlässigen Knoten

Eine zentralisierte Datenspeicherung und Koordination stellt für viele verteilte Algorithmen einen bedeutenden Flaschenhals hinsichtlich Skalierbarkeit und Zuverlässigkeit dar. Im Folgenden wird ein Ansatz vorgestellt, der u.a. zur Realisierung eines vollständig dezentralen verteilten Webcrawlers eingesetzt wird. Seine wesentlichen Eigenschaften bestehen in Durchsetzung einer Verpflichtung alle...
