In Unter den Brücken sieht man die Frauen oben auf Brücken. Am Fenster ihres Ullstein-Büros imaginiert Vicki Baum Idee einer Telefonistin vor der Schaltwand und transferiert so ihren Roman in ein Theaterstück. Baum, am Brückengeländer kehren alle Rücken zum übrigen Raum. Und genauso ausgerichtet sitzen auch Studierenden bei berühmten Sit-ins US-Bürgerrechtsbewegung Lunch Counter. Kaum bekannt h...

In this paper, we present methods to analyze dialog coherence that help us to automatically distinguish between coherent and incoherent conversations. We build a machine learning classifier using local transition patterns that span over adjacent dialog turns and encode lexical as well as semantic information in dialogs. We evaluate our algorithm on the Switchboard dialog corpus by treating orig...

Software development in distributed computation is complicated by the extra overhead of communication between connected, dispersed hosts in dynamically changing, multiple administrative domains. Many disparate technologies exist for trust management, authentication, secure communication channels, and service discovery, but composing all of these elements into a single system can outweigh princi...

Active learning techniques were employed for classification of dialogue acts over two dialogue corpora, the English humanhuman Switchboard corpus and the Spanish human-machine Dihana corpus. It is shown clearly that active learning improves on a baseline obtained through a passive learning approach to tagging the same data sets. An error reduction of 7% was obtained on Switchboard, while a fact...

Topic detection in dialogue datasets has become a significant challenge for unsupervised and unlabeled data to develop cohesive engaging system. In this paper, we proposed semi-supervised techniques topic the conversational dataset compared them with existing techniques. The paper proposes novel approach detection, which takes preprocessed as an input performs similarity analysis TF-IDF scores ...
