Das Teilprojekt B08 im Sonderforschungsbereich HAEC hat sich zum Ziel gesetzt, Energieeffizienz und Adaptivität der geplanten HAEC Computerarchitektur anhand von praktisch relevanten Anwendungen im Bereich Wissensgraphen zu zeigen. Dazu entwickelt das Teilprojekt deklarative Ontologiesprachen zur Modellierung komplexer Zusammenhängen einerseits und effiziente Graph-Datenbanken und -Analyseplattformen anderseits. Ein zentrales Elemetn zur Integration beider Aspekte ist die Unterstützung ausdrucksstarker Abfragesprachen, in welche die deklarativ spezifizierten Berechnungsaufgaben übersetzt werden können.

Das Projekt soll anhand mehrerer Anwendungsfälle evaluiert werden. Ein solcher Anwendungsfall ist die deklarative Analyse des Wissensgraphen in Wikidata. Ein weiterer Anwendungsfall ist die Erkennung dynamischer Kontexte, wie sie im HAEC Teilprojekt B02 (Baader/Turhan) benötigt wird.
