• Abstract summary: We introduce Situated Interactive MultiModal Conversations (SIMMC) as a new direction aimed at training agents. We provide two SIMMC datasets totalling 13K human-human dialogs (169K utterances) using a multimodal Wizard-of-Oz (WoZ) setup. We present several tasks within SIMMC as objective evaluation protocols, such as Structural API Prediction and Response Generation.

• Abstract: Next generation virtual assistants are envisioned to handle multimodal inputs (e.g., vision, memories of previous interactions, in addition to the user's utterances), and perform multimodal actions (e.g., displaying a route in addition to generating the system's utterance). We introduce Situated Interactive MultiModal Conversations (SIMMC) as a new direction aimed at training agents that take multimodal actions grounded in a co-evolving multimodal input context in addition to the dialog history. We provide two SIMMC datasets totalling ~13K human-human dialogs (~169K utterances) using a multimodal Wizard-of-Oz (WoZ) setup, on two shopping domains: (a) furniture (grounded in a shared virtual environment) and, (b) fashion (grounded in an evolving set of images). We also provide logs of the items appearing in each scene, and contextual NLU and coreference annotations, using a novel and unified framework of SIMMC conversational acts for both user and assistant utterances. Finally, we present several tasks within SIMMC as objective evaluation protocols, such as Structural API Prediction and Response Generation. We benchmark a collection of existing models on these SIMMC tasks as strong baselines, and demonstrate rich multimodal conversational interactions. Our data, annotations, code, and models are publicly available.

  We propose a parameter-efficient prompt-tuning method named DialCLIP for multi-modal dialog retrieval. Our approach introduces a multi-modal context generator to learn context features which are distilled into prompts within the pre-trained vision-language model CLIP. To facilitate various types of retrieval, we also design multiple experts to learn mappings from CLIP outputs to multi-modal representation space.

  We argue that both the feature multimodality and conversational contextualization should be properly modeled simultaneously during the feature disentanglement and fusion steps. We propose a Contribution-aware Fusion Mechanism (CFM) and a Context Refusion Mechanism ( CRM) for multimodal and context integration. Our system achieves new state-of-the-art performance consistently.

  With the surge of virtual assistants with screen, the next generation of agents are required to understand screen context. We propose a novel multimodal conversational framework, where the dialogue agent's next action and their arguments are derived jointly conditioned both on the conversational and the visual context. Our model can recognize visual features such as color and shape as well as the metadata based features such as price or star rating associated with a visual entity.
