• Abstract summary: PRESTO is a dataset of over 550K contextual multilingual conversations between humans and virtual assistants. It contains challenges that occur in real-world NLU tasks such as disfluencies, code-switching, and revisions. Our mT5 model based baselines demonstrate that the conversational phenomenon present in PRESTO are challenging to model.

• Abstract: Research interest in task-oriented dialogs has increased as systems such as Google Assistant, Alexa and Siri have become ubiquitous in everyday life. However, the impact of academic research in this area has been limited by the lack of datasets that realistically capture the wide array of user pain points. To enable research on some of the more challenging aspects of parsing realistic conversations, we introduce PRESTO, a public dataset of over 550K contextual multilingual conversations between humans and virtual assistants. PRESTO contains a diverse array of challenges that occur in real-world NLU tasks such as disfluencies, code-switching, and revisions. It is the only large scale human generated conversational parsing dataset that provides structured context such as a user's contacts and lists for each example. Our mT5 model based baselines demonstrate that the conversational phenomenon present in PRESTO are challenging to model, which is further pronounced in a low-resource setup.

  Virtual assistants are poised to take a leap forward in terms of their dialogue capabilities. Yet a major bottleneck to achieving genuinely transformative task-oriented dialogue capabilities remains the scarcity of high quality data. We use LUCID to generate a seed dataset of 4,277 conversations across 100 intents to demonstrate its capabilities.

  We propose dialogs for connected memories as a powerful tool to empower users to search their media collection through a multi-turn, interactive conversation. We use a new task-oriented dialog dataset COMET, which contains $11.5k$ user->assistant dialogs (totaling $103k$ utterances) grounded in simulated personal memory graphs. We analyze COMET, formulate four main tasks to benchmark meaningful progress, and adopt state-of-the-art language models as strong baselines.

  We propose Database Search Result (DSR) Disambiguation, a novel task that focuses on disambiguating database search results. To study this task, we augment the popular task-oriented dialog datasets (MultiWOZ and SGD) with turns that resolve ambiguities by (a) synthetically generating turns through a pre-defined grammar, and (b) collecting human paraphrases for a subset. We find that training on our augmented dialog data improves the model's ability to deal with ambiguous scenarios, without sacrificing performance on unmodified turns.
