    Refining Implicit Argument Annotation for UCCA

    Full text link
    Predicate-argument structure analysis is a central component in meaning representations of text. The fact that some arguments are not explicitly mentioned in a sentence gives rise to ambiguity in language understanding, and renders it difficult for machines to interpret text correctly. However, only few resources represent implicit roles for NLU, and existing studies in NLP only make coarse distinctions between categories of arguments omitted from linguistic form. This paper proposes a typology for fine-grained implicit argument annotation on top of Universal Conceptual Cognitive Annotation's foundational layer. The proposed implicit argument categorisation is driven by theories of implicit role interpretation and consists of six types: Deictic, Generic, Genre-based, Type-identifiable, Non-specific, and Iterated-set. We exemplify our design by revisiting part of the UCCA EWT corpus, providing a new dataset annotated with the refinement layer, and making a comparative analysis with other schemes.Comment: DMR 202

    Control of virtual environments for young people with learning difficulties

    Purpose: The objective of this research is to identify the requirements for the selection or development of usable virtual environment (VE) interface devices for young people with learning disabilities. Method: a user-centred design methodology was employed, to produce a design specification for usable VE interface devices. Details of the users' cognitive, physical and perceptual abilities were obtained through observation and normative assessment tests. Conclusions : A review of computer interface technology, including virtual reality and assistive devices, was conducted. As there were no devices identified that met all the requirements of the design specification, it was concluded that there is a need for the design and development of new concepts. Future research will involve concept and prototype development and user-based evaluation of the prototypes

    A Thick Industrial Design Studio Curriculum

    This presentation was part of the session : Pedagogy: Procedures, Scaffolds, Strategies, Tactics24th National Conference on the Beginning Design StudentThis paper describes an industrial design studio course based in a private university in Izmir, Turkey where second year industrial design students, for the first time, engage in a studio project. The design studio course emphasises three distinct areas of competence in designing that are the focus of the curriculum. They are; design process: the intellectual act of solving a design problem; design concept: the imagination and sensibility to conceive of appropriate design ideas; and presentation: the ability to clearly and evocatively communicate design concepts. The studio is 'thick' with materials, tasks and activities that are intentionally sequenced to optimise learning in a process that is known as educational 'scaffolding.' The idea of a process--a patient journey toward it's destination, is implicit in the studio that is full of opportunities for reflection-in-action. A significant feature is the importance placed on drawing and model making. An exemplary design process should show evidence of 'breadth'--meaning a wide search for solutions where a range of alternatives explored throughout; followed by an incremental refinement of the chosen solution where elements of the final design concept are developed thoroughly and in detail--called 'depth.' Learning to design is predicated on an engagement in and manipulation of the elements of the design problem. Evidence of that learning will be found by examining the physical materials and results of the design process. The assessment criteria are published with the brief at the outset of design project and outcomes are spelt out at the end. Students are remind throughout project of the criteria, which is to say they are reminded of pedagogical aims of the studio. Assessment criteria are detailed and the advantages of summative assessment are described

    Revisiting the link between teaching and learning research and practice: Authentic learning and design-based research

    Get PDF
    It has often been argued that research in teaching and learning has only a weak link to practice. Much educational research is criticised for having little relevance to the day-to-day learning experience of students in K-12 and higher education. This criticism is particularly relevant in relation to educational technology research. In this field, many researchers conduct studies that are designed to test the effectiveness of the delivery medium—to prove that one medium is better than another—rather than exploring ways to improve instructional approaches and tasks. With the current proliferation of exciting and innovative technologies that are likely to become more and more common in classrooms (such as cell phones, tablets, and other mobile devices), research needs to move beyond simple comparisons of these devices with each other or with the ‘traditional’ approach. In this presentation, I argue that educational technology research has largely failed to change educational practice and outcomes because of the predominant aim of such research to prove rather than improve. Online and mobile technologies afford the design and creation of truly innovative authentic learning designs, where the technology is both a tool and a platform for presentation of genuine products, and the focus is on learning with technologies rather than from them. Instead of comparative research, a more powerful and appropriate approach is design-based research, where researchers and practitioners work hand in hand to iteratively refine innovations until they get the results they seek. A description of the characteristics of design-based research is given, together with an argument for the more widespread adoption of this approach to enhance the quality and impact of research in teaching and learning

    Annotating patient clinical records with syntactic chunks and named entities: the Harvey corpus

    Get PDF
    The free text notes typed by physicians during patient consultations contain valuable information for the study of disease and treatment. These notes are difficult to process by existing natural language analysis tools since they are highly telegraphic (omitting many words), and contain many spelling mistakes, inconsistencies in punctuation, and non-standard word order. To support information extraction and classification tasks over such text, we describe a de-identified corpus of free text notes, a shallow syntactic and named entity annotation scheme for this kind of text, and an approach to training domain specialists with no linguistic background to annotate the text. Finally, we present a statistical chunking system for such clinical text with a stable learning rate and good accuracy, indicating that the manual annotation is consistent and that the annotation scheme is tractable for machine learning

    Rising to the challenge: supporting educators without arts experience in the delivery of authentic arts learning

    Get PDF
    Educators, policy makers and researchers have repeatedly affirmed the significance of a quality arts education in developing the capabilities necessary for 21st century citizenship. However, facilitating an Arts education can be extremely challenging, especially for the generalist classroom teacher who may not possess the necessary background learning across all five arts subjects. Revelations from the first phase of my doctoral research with Australian home educating parents identified a similar dilemma with the delivery of authentic Arts learning in home contexts. A significant proportion of the home educator study participants admitted to no educational or artistic training. My doctoral research project has sought to understand how Australian home educators approach arts education, of the challenges they face, and the way that existing knowledge and strengths are harnessed in delivering their children’s education. Moreover, using a Design Based Research approach, I have attempted to generate transformational research by working collaboratively with home educators to enact solutions to identified problems. This has resulted in the development and refinement of a website and online community aimed at supporting and enhancing home educators in the development of authentic arts learning, in addition to theoretical guidelines that can be applied to similar contexts. Thus, whilst home education is considered pedagogically distinct from institutional education, the findings of this project have highlighted that the challenges faced by home educating parents are very much like those faced by the generalist classroom teacher, and that similar means of support may be transferred across contexts
