1. -9199-0633. Continually improving grounded natural language understanding through human-robot dialog.

Degree: PhD, Computer Science, 2018, University of Texas – Austin

As robots become ubiquitous in homes and workplaces such as hospitals and factories, they must be able to communicate with humans. Several kinds of knowledge are required to understand and respond to a human's natural language commands and questions. If a person requests an assistant robot to take me to Alice's office, the robot must know that Alice is a person who owns some unique office, and that take me means it should navigate there. Similarly, if a person requests bring me the heavy, green mug, the robot must have accurate mental models of the physical concepts heavy, green, and mug. To avoid forcing humans to use key phrases or words robots already know, this thesis focuses on helping robots understanding new language constructs through interactions with humans and with the world around them. To understand a command in natural language, a robot must first convert that command to an internal representation that it can reason with. Semantic parsing is a method for performing this conversion, and the target representation is often semantic forms represented as predicate logic with lambda calculus. Traditional semantic parsing relies on hand-crafted resources from a human expert: an ontology of concepts, a lexicon connecting language to those concepts, and training examples of language with abstract meanings. One thrust of this thesis is to perform semantic parsing with sparse initial data. We use the conversations between a robot and human users to induce pairs of natural language utterances with the target semantic forms a robot discovers through its questions, reducing the annotation effort of creating training examples for parsing. We use this data to build more dialog-capable robots in new domains with much less expert human effort (Thomason et al., 2015; Padmakumar et al., 2017). Meanings of many language concepts are bound to the physical world. Understanding object properties and categories, such as heavy, green, and mug requires interacting with and perceiving the physical world. Embodied robots can use manipulation capabilities, such as pushing, picking up, and dropping objects to gather sensory data about them. This data can be used to understand non-visual concepts like heavy and empty (e.g. get the empty carton of milk from the fridge), and assist with concepts that have both visual and non-visual expression (e.g. tall things look big and also exert force sooner than short things when pressed down on). A second thrust of this thesis focuses on strategies for learning these concepts using multi-modal sensory information. We use human-in-the-loop learning to get labels between concept words and actual objects in the environment (Thomason et al., 2016, 2017). We also explore ways to tease out polysemy and synonymy in concept words (Thomason and Mooney, 2017) such as light, which can refer to a weight or a color, the latter sense being synonymous with pale. Additionally, pushing, picking up, and dropping objects to gather sensory information is prohibitively time-consuming, so we investigate strategies for… Advisors/Committee Members: Mooney, Raymond J.

2. Birger, Mark. Dialogový systém pro komunikaci s reálným robotem: Dialogue System for Human-Robot Communication.

Degree: 2019, Brno University of Technology

In this thesis a problematic of spoken dialog systems was discovered. The dialog system framework was developed for a fast implementation of spoken dialog interfaces for existing robotics software. This framework allows describing a dialog flow in special markup format, which allows scope variables manipulating and controlling a flow of general-purpose programming language software by user input phrase. Markup language is designed for asynchronous function execution and subsequent manipulations with them. It allows robot to solve tasks simultaneously. Developed framework uses Link Grammar Parser for natural language processing. With this framework was implemented a dialog system instance for PR2 robot control. Advisors/Committee Members: Smrž, Pavel (advisor), Materna, Zdeněk (referee).
