Double Topic Shifts in Open Domain Conversations: Natural Language Interface for a Wikipedia-based Robot Application
نویسندگان
چکیده
The paper describes topic shifting in dialogues with a robot that provides information from Wikipedia. The work focuses on a double topical construction of dialogue coherence which refers to discourse coherence on two levels: the evolution of dialogue topics via the interaction between the user and the robot system, and the creation of discourse topics via the content of the Wikipedia article itself. The user selects topics that are of interest to her, and the system builds a list of potential topics, anticipated to be the next topic, by the links in the article and by the keywords extracted from the article. The described system deals with Wikipedia articles, but could easily be adapted to other digital information providing systems.
