Unified Conversational Models with System-Initiated Transitions between Chit-Chat and Task-Oriented Dialogues
Ye Liu, Stefan Ultes, Wolfgang Minker +1
Spoken dialogue systems (SDSs) have been separately developed under two different categories, task-oriented and chit-chat. The former focuses on achieving functional goals and the…
ConceptNet infused DialoGPT for Underlying Commonsense Understanding and Reasoning in Dialogue Response Generation
Ye Liu, Wolfgang Maier, Wolfgang Minker +1
The pre-trained conversational models still fail to capture the implicit commonsense (CS) knowledge hidden in the dialogue interaction, even though they were pre-trained with an en…
Context Matters in Semantically Controlled Language Generation for Task-oriented Dialogue Systems
Ye Liu, Wolfgang Maier, Wolfgang Minker +1
This work combines information about the dialogue history encoded by pre-trained model with a meaning representation of the current system utterance to realize contextual language…
Empathetic Dialogue Generation with Pre-trained RoBERTa-GPT2 and External Knowledge
Ye Liu, Wolfgang Maier, Wolfgang Minker +1
One challenge for dialogue agents is to recognize feelings of the conversation partner and respond accordingly. In this work, RoBERTa-GPT2 is proposed for empathetic dialogue gener…
Naturalness Evaluation of Natural Language Generation in Task-oriented Dialogues using BERT
Ye Liu, Wolfgang Maier, Wolfgang Minker +1
This paper presents an automatic method to evaluate the naturalness of natural language generation in dialogue systems. While this task was previously rendered through expensive an…
TuLiPA: Towards a Multi-Formalism Parsing Environment for Grammar Engineering
Laura Kallmeyer, Timm Lichte, Wolfgang Maier +3
In this paper, we present an open-source parsing environment (Tuebingen Linguistic Parsing Architecture, TuLiPA) which uses Range Concatenation Grammar (RCG) as a pivot formalism,…
