Embodied Multimodal Agents to Bridge the Understanding Gap
In this paper we argue that embodied multimodal agents, i. e., avatars, can play an important role in moving natural language processing toward “deep understanding.” Fully-featured interactive agents, model encounters between two “people,” but a language-only agent has little environmental and situational awareness.
Exploiting Embodied Simulation to Detect Novel Object Classes Through Interaction
In this paper we present a novel method for a naive agent to detect novel objects it encounters in an interaction.
Neurosymbolic AI for Situated Language Understanding
In recent years, data-intensive AI, particularly the domain of natural language processing and understanding, has seen significant progress driven by the advent of large datasets and deep neural networks that have sidelined more classic AI approaches to the field.
Situated Multimodal Control of a Mobile Robot: Navigation through a Virtual Environment
We present a new interface for controlling a navigation robot in novel environments using coordinated gesture and language.
A Formal Analysis of Multimodal Referring Strategies Under Common Ground
In this paper, we present an analysis of computationally generated mixed-modality definite referring expressions using combinations of gesture and linguistic descriptions.
Multimodal Continuation-style Architectures for Human-Robot Interaction
We present an architecture for integrating real-time, multimodal input into a computational agent's contextual model.
Generating a Novel Dataset of Multimodal Referring Expressions
Referring expressions and definite descriptions of objects in space exploit information both about object characteristics and locations.
Situational Grounding within Multimodal Simulations
In this paper, we argue that simulation platforms enable a novel type of embodied spatial reasoning, one facilitated by a formal model of object and event semantics that renders the continuous quantitative search space of an open-world, real-time environment tractable.
Combining Deep Learning and Qualitative Spatial Reasoning to Learn Complex Structures from Sparse Examples with Noise
We present a novel approach to introducing new spatial structures to an AI agent, combining deep learning over qualitative spatial relations with various heuristic search algorithms.
Every Object Tells a Story
Most work within the computational event modeling community has tended to focus on the interpretation and ordering of events that are associated with verbs and event nominals in linguistic expressions.
Building Multimodal Simulations for Natural Language
Simulation and automatic visualization of events from natural language descriptions and supplementary modalities, such as gestures, allows humans to use their native capabilities as linguistic and visual interpreters to collaborate on tasks with an artificial agent or to put semantic intuitions to the test in an environment where user and agent share a common context. In previous work (Pustejovsky and Krishnaswamy, 2014; Pustejovsky, 2013a), we introduced a method for modeling natural language expressions within a 3D simulation environment built on top of the game development platform Unity (Goldstone, 2009).
VoxSim: A Visual Platform for Modeling Motion Language
Much existing work in text-to-scene generation focuses on generating static scenes.
The Development of Multimodal Lexical Resources
Human communication is a multimodal activity, involving not only speech and written expressions, but intonation, images, gestures, visual clues, and the interpretation of actions through perception.
Generating Simulations of Motion Events from Verbal Descriptions
The generated simulations act as a conceptual "debugger" for the semantics of different motion verbs: that is, by testing for consistency and informativeness in the model, simulations expose the presuppositions associated with linguistic expressions and their compositions.
ECAT: Event Capture Annotation Tool
This paper introduces the Event Capture Annotation Tool (ECAT), a user-friendly, open-source interface tool for annotating events and their participants in video, capable of extracting the 3D positions and orientations of objects in video captured by Microsoft's Kinect(R) hardware.
VoxML: A Visualization Modeling Language
We present the specification for a modeling language, VoxML, which encodes semantic knowledge of real-world objects represented as three-dimensional models, and of events and attributes related to and enacted over these objects.
Multimodal Semantic Simulations of Linguistically Underspecified Motion Events
In this paper, we describe a system for generating three-dimensional visual simulations of natural language motion expressions.
