A Scenario Description Language Based on Action Frame

Hong Hui Zhang, Atsushi Ohnishi
2003 International Conference on Advanced Information Systems Engineering  
This paper describes a language for describing scenarios in which simple action traces are embellished to include typed frames based on a simple case grammar of actions.  ...  Scenarios are informal, and are difficult to be processed automatically.  ...  Scenarios can be regarded as a sequence of events. Each event corresponds to a certain action. We have developed a scenario description language based on this notion.  ...

PixL2R: Guiding Reinforcement Learning Using Natural Language by Mapping Pixels to Rewards [article]

Prasoon Goyal, Scott Niekum, Raymond J. Mooney
2020 arXiv   pre-print
In this work, we propose a model that directly maps pixels to rewards, given a free-form natural language description of the task, which can then be used for policy learning.  ...  Our experiments on the Meta-World robot manipulation domain show that language-based rewards significantly improves the sample efficiency of policy learning, both in sparse and dense reward settings.  ...  As such, a description collected for one scenario for a task can be paired with any of the 100 scenarios for the corresponding task.  ...

Interactive Planning of Manual Assembly Operations: From Language to Motion

Stephan Busemann, Jörg Steffen, Erik Herrmann
2016 Procedia CIRP  
We suggest solutions to the subtask of mapping textual descriptions onto motion sequences. Consider a description like "Tighten arm support with cordless screw driver on center console".  ...  Evaluating this kind of condition-action rules against constraints imposed by the scene for a given textual description leads to a sequence of elementary actions that is then processed further and visualized  ...  Breakdown of task descriptions The breakdown of a case frame into elementary actions depends on the state of the scenario the action shall be carried out on.  ...

Frame Interpretation and Validation in a Open Domain Dialogue System [article]

Artur Ventura, Nuno Diegues, David Martins de Matos
2012 arXiv   pre-print
Our goal in this paper is to establish a means for a dialogue platform to be able to cope with open domains considering the possible interaction between the embodied agent and humans.  ...  To this end we present an algorithm capable of processing natural language utterances and validate them against knowledge structures of an intelligent agent's mind.  ...  Also, each language possesses a grammar description: each verb on the language has an associated set of structural (NP VP NP) and semantic (Agent V Object) relations between itself and its arguments.  ...

perform tasks based on incomplete natural language instructions.  ...  However, natural language instructions are often missing information that would be obvious to a human based on environmental context and common sense, and hence does not need to be explicitly stated.  ...  In this way, we can construct a test scenario with k candidates, where one of them is plausible based on the human annotation.  ...

The University of Sheffield and University of Engineering & Technology, Lahore at TRECVID 2016: Video to Text Description Task

Samyan Qayyum Wahla, Sahar Waqar, Muhammad Usman Ghani Khan, Yoshihiko Gotoh
2016 TREC Video Retrieval Evaluation  
Our approach is based on the extraction of high level features using image processing and computer vision stage, scene recognition using HLFs with machine learning approach and generation of natural language  ...  Second approach is totally based on facial features and gestures. Third approach is similar to first approach but machine learning approach is replaced with deep learning.  ...  Natural Language Generation Stage Action is recognized per 8 frames which mean ADR gives no output per 7 frames and on 8th frame sentence contains a verb.  ...

Speech Communication in Teaching a Foreign Language

2019 International journal of recent technology and engineering  
One of the main modules in the system of any developed language is the sublanguage of everyday communication.The article deals with interpersonal communication in teaching foreign languages.  ...  A language is considered not only and not so much as a system of organized levels, but primarily as a system of a number of sub-languages or modules, each of which, in turn, has a system organization.  ...  The concept is thus based on the concept of "language in action".  ...

2020 arXiv   pre-print
Language can represent complex scenarios and concepts, making it a favorable candidate for representation.  ...  While previous methods focused on information in its raw form (e.g., raw visual input), we propose to represent the state using natural language.  ...  In each patch, objects were counted, and a sentence description was constructed based on this information.  ...
