Omkar Patil, Lena Reed, Kevin K. Bowden +12
Conversational agents are consistently growing in popularity and many people interact with them every day. While many conversational agents act as personal assistants, they can hav…
Jurassic is (almost) All You Need: Few-Shot Meaning-to-Text Generation for Open-Domain Dialogue
Lena Reed, Cecilia Li, Angela Ramirez +2
One challenge with open-domain dialogue systems is the need to produce truthful, high-quality responses on any topic. We aim to improve the quality and coverage of Athena, an Alexa…
Athena 2.0: Contextualized Dialogue Management for an Alexa Prize SocialBot
Juraj Juraska, Kevin K. Bowden, Lena Reed +12
Athena 2.0 is an Alexa Prize SocialBot that has been a finalist in the last two Alexa Prize Grand Challenges. One reason for Athena's success is its novel dialogue management strat…

Learning from Mistakes: Combining Ontologies via Self-Training for Dialogue Generation
Lena Reed, Vrindavan Harrison, Shereen Oraby +2
Natural language generators (NLGs) for task-oriented dialogue typically take a meaning representation (MR) as input. They are trained end-to-end with a corpus of MR/utterance pairs…
Maximizing Stylistic Control and Semantic Accuracy in NLG: Personality Variation and Discourse Contrast
Vrindavan Harrison, Lena Reed, Shereen Oraby +1
Neural generation methods for task-oriented dialogue typically generate from a meaning representation that is populated using a database of domain information, such as a table of d…
Can Neural Generators for Dialogue Learn Sentence Planning and Discourse Structuring?
Lena Reed, Shereen Oraby, Marilyn Walker
Responses in task-oriented dialogue systems often realize multiple propositions whose ultimate form depends on the use of sentence planning and discourse structuring operations. Fo…
Neural MultiVoice Models for Expressing Novel Personalities in Dialog
Shereen Oraby, Lena Reed, Sharath TS +2
Natural language generators for task-oriented dialog should be able to vary the style of the output utterance while still effectively realizing the system dialog actions and their…
Controlling Personality-Based Stylistic Variation with Neural Natural Language Generators
Shereen Oraby, Lena Reed, Shubhangi Tandon +3
Natural language generators for task-oriented dialogue must effectively realize system dialogue actions and their associated semantics. In many applications, it is also desirable f…
