    The Semantics of Article Acquisition

    Get PDF
    Accurately using articles has consistently been a difficult task for English language learners as articles are often treated as solely grammatical forms rather than also recognizing as representatives of complex semantic properties. This paper aims to synthesize individual research on semantic factors which influence article acquisition and explore how they interact with each other. This paper especially focuses on how native and second language speakers of English acquire and understand the concepts of definiteness and specificity and explores these features within the framework of Chomsky’s theory of Universal Grammar. This paper examines the Fluctuating Hypothesis (FH) and its use as a theoretical framework for a variety of modern article acquisition research. The theory states that ELLs have access to Universal Grammar when discovering the parameters for the semantic categories of definiteness and specificity. This paper then explains the interaction between the FH and transfer in language learners from both article-based and articleless language backgrounds, concluding that transfer does not override the effects of the FH. Additional semantic factors such as countability, plurality, and idiomatic phrase structures are also discussed in this paper, emphasizing the many complex layers ELLs must learn to navigate. This paper examines recent attempts to create linguistically informed article instruction, some of which incorporate concepts from the FH. Finally, the paper provides guidelines for English language instructors, stressing the importance of understanding features of their students’ native language, building students’ awareness of the complexities associated with article use, and correcting their misconceptions of specificity and definiteness

    Building Machines That Learn and Think Like People

    Recent progress in artificial intelligence (AI) has renewed interest in building systems that learn and think like people. Many advances have come from using deep neural networks trained end-to-end in tasks such as object recognition, video games, and board games, achieving performance that equals or even beats humans in some respects. Despite their biological inspiration and performance achievements, these systems differ from human intelligence in crucial ways. We review progress in cognitive science suggesting that truly human-like learning and thinking machines will have to reach beyond current engineering trends in both what they learn, and how they learn it. Specifically, we argue that these machines should (a) build causal models of the world that support explanation and understanding, rather than merely solving pattern recognition problems; (b) ground learning in intuitive theories of physics and psychology, to support and enrich the knowledge that is learned; and (c) harness compositionality and learning-to-learn to rapidly acquire and generalize knowledge to new tasks and situations. We suggest concrete challenges and promising routes towards these goals that can combine the strengths of recent neural network advances with more structured cognitive models.Comment: In press at Behavioral and Brain Sciences.

    The 1990 progress report and future plans

    Get PDF
    This document describes the progress and plans of the Artificial Intelligence Research Branch (RIA) at ARC in 1990. Activities span a range from basic scientific research to engineering development and to fielded NASA applications, particularly those applications that are enabled by basic research carried out at RIA. Work is conducted in-house and through collaborative partners in academia and industry. Our major focus is on a limited number of research themes with a dual commitment to technical excellence and proven applicability to NASA short, medium, and long-term problems. RIA acts as the Agency's lead organization for research aspects of artificial intelligence, working closely with a second research laboratory at JPL and AI applications groups at all NASA centers

    Emerging Artificial Societies Through Learning

    Get PDF
    The NewTies project is implementing a simulation in which societies of agents are expected to de-velop autonomously as a result of individual, population and social learning. These societies are expected to be able to solve environmental challenges by acting collectively. The challenges are in-tended to be analogous to those faced by early, simple, small-scale human societies. This report on work in progress outlines the major features of the system as it is currently conceived within the project, including the design of the agents, the environment, the mechanism for the evolution of language and the peer-to-peer infrastructure on which the simulation runs.Artificial Societies, Evolution of Language, Decision Trees, Peer-To-Peer Networks, Social Learning

    A Knowledge Graph Construction Approach for Legal Domain

    Get PDF
    Considering that the existing domain knowledge graphs have difficulty in updating data in a timely manner and cannot make use of knowledge sufficiently in the construction process, this paper proposes a legal domain knowledge graph construction approach based on \u27China Judgments Online\u27 in order to manage the cases\u27 knowledge contained in it. The construction process is divided into two steps. First, we extract the classification relationships of the cases from structured data. Then, we obtain attribute knowledge of cases from semi-structured data and unstructured data through a relationship extraction model based on an improved cross-entropy loss function. The triples describing knowledge of cases are stored through Neo4j. The accuracy of the proposed approach is verified through experiments and we construct a legal domain knowledge graph which contains more than 4K classification relationships and 12K attribute knowledge to prove its validity

    Proceedings of the ECCS 2005 satellite workshop: embracing complexity in design - Paris 17 November 2005

    Embracing complexity in design is one of the critical issues and challenges of the 21st century. As the realization grows that design activities and artefacts display properties associated with complex adaptive systems, so grows the need to use complexity concepts and methods to understand these properties and inform the design of better artifacts. It is a great challenge because complexity science represents an epistemological and methodological swift that promises a holistic approach in the understanding and operational support of design. But design is also a major contributor in complexity research. Design science is concerned with problems that are fundamental in the sciences in general and complexity sciences in particular. For instance, design has been perceived and studied as a ubiquitous activity inherent in every human activity, as the art of generating hypotheses, as a type of experiment, or as a creative co-evolutionary process. Design science and its established approaches and practices can be a great source for advancement and innovation in complexity science. These proceedings are the result of a workshop organized as part of the activities of a UK government AHRB/EPSRC funded research cluster called Embracing Complexity in Design (www.complexityanddesign.net) and the European Conference in Complex Systems (complexsystems.lri.fr).
