How can we detect topic shifts? How dowe know whether a topic is closed or still ongoing? In the context of our BielefeldKnowCIT1 project we are building an artificial agent that can do such things!Topic awareness in spoken dialogs is based on cognitive and interactive pro-cesses taking place unconsciously during conversation. Bublitz [1] defined a di-alog topic to be a category subordinating and enclosing a sequence of associateddialog utterances. We pick up this idea in the context of recent research on socialnetworks by making use of Wikipedia which provides huge amounts of categoriessubordinating object knowledge by means of natural language articles [2].Adapting the tasks of the Topic Detection and Tracking research program [3]to spontaneous dialogs, our model implements six tasks essential for automatictopic awareness on the basis of a graphical representation of the Wikipedia cate-gory system. Thereby the processes completing the several tasks operate onlineto handle (dialog) streams of ever-changing topical threads in real-time. Eventu-ally transferring these tasks to our conversational agent Max means transferringhuman-like topic awareness to the artificial dialog partner and thus facilitates talk-ing topically to him.References[1] Bublitz, Wolfram. 1989.
