A pragmatic approach to semantic repositories benchmarking

The aim of this paper is to benchmark various semantic repositories in order to evaluate their deployment in a commercial image retrieval and browsing application. We adopt a two-phase approach for evaluating the target semantic repositories: analytical parameters such as query language and reasoning support are used to select the pool of the target repositories, and practical parameters such as load and query response times are used to select the best match to application requirements. In addition to utilising a widely accepted benchmark for OWL repositories (UOBM), we also use a real-life dataset from the target application, which provides us with the opportunity of consolidating our findings. A distinctive advantage of this benchmarking study is that the essential requirements for the target system such as the semantic expressivity and data scalability are clearly defined, which allows us to claim contribution to the benchmarking methodology for this class of applications

Pragmatic Holism

The reductionist/holist debate seems an impoverished one, with many participants appearing to adopt a position first and constructing rationalisations second. Here I propose an intermediate position of pragmatic holism, that irrespective of whether all natural systems are theoretically reducible, for many systems it is completely impractical to attempt such a reduction, also that regardless if whether irreducible `wholes' exist, it is vain to try and prove this in absolute terms. This position thus illuminates the debate along new pragmatic lines, and refocusses attention on the underlying heuristics of learning about the natural world

Pragmatic ability and disability as emergent phenomena

A holistic approach to pragmatic ability and disability is outlined which takes account both of the behaviour of individuals involved in the communicative process, and also of the underlying factors which contribute to such behaviour. Rather than being seen as resulting directly from a dysfunction in some kind of discrete pragmatic ‘module’ or behavioural mechanism, pragmatic impairment and also normal pragmatic functioning are instead viewed as the emergent consequence of interactions between linguistic, cognitive and sensorimotor processes which take place both within and between individuals

Unified Pragmatic Models for Generating and Following Instructions

We show that explicit pragmatic inference aids in correctly generating and following natural language instructions for complex, sequential tasks. Our pragmatics-enabled models reason about why speakers produce certain instructions, and about how listeners will react upon hearing them. Like previous pragmatic models, we use learned base listener and speaker models to build a pragmatic speaker that uses the base listener to simulate the interpretation of candidate descriptions, and a pragmatic listener that reasons counterfactually about alternative descriptions. We extend these models to tasks with sequential structure. Evaluation of language generation and interpretation shows that pragmatic inference improves state-of-the-art listener models (at correctly interpreting human instructions) and speaker models (at producing instructions correctly interpreted by humans) in diverse settings.Comment: NAACL 2018, camera-ready versio

Editorial. Clinical pragmatics: an emergentist perspective

[First Paragraph] Clinical pragmatics has been a major growth area in clinical linguistics and speech and language pathology over the past two decades. Its scope is vast: if we define pragmatics in broad terms, there are no communicative disorders which do not involve pragmatic impairment at least to some degree (Perkins, 2003). Early work in the area tended to focus on the application of pragmatic theory in the analysis of pragmatic impairment (e.g. speech act theory (Hirst, LeDoux, & Stein, 1984), conversational implicature (Damico, 1985) and, more recently, relevance theory (Leinonen & Kerbel, 1999)) and on the development of pragmatic assessments, tests and profiles which included a theoretically eclectic range of items drawn from both pragmatic theory and elsewhere (e.g. Bishop, 1998; Penn, 1985; Prutting & Kirchner, 1983). In more recent years there has been an increasing interest in the neurological and cognitive bases of pragmatic impairment (e.g. Paradis, 1998; Perkins, 2000; Stemmer, 1999) and in the use of interactional approaches such as conversation analysis (e.g. Goodwin, 2003). This special issue of Clinical Linguistics and Phonetics draws on all of these areas but focuses on a particular aspect of pragmatic impairment which has often been overlooked – namely, that the behaviours we describe as pragmatic impairments are in fact the outcome of very varied and highly complex processes. This neglect is partly due to a common tendency to see pragmatics as a separate ‘level’ or even ‘module’ of language, on a par with syntax and semantics. Influenced on the one hand by speech act theory, with its distinction between language structure and communicative acts, and on the other hand by clinical populations who were either able to communicate well despite being linguistically impaired or else were poor communicators despite having good linguistic ability, clinicians assumed there to be a clear dissociation between linguistic and pragmatic competence. Although there is still considerable neurological evidence for a broadly modular view in terms of the lateralisation of linguistic and pragmatic functions, there is also compelling evidence for seeing pragmatic impairment as a more complex, non-unitary phenomenon. Non-modular, or ‘interactional’, views of pragmatic impairment have been influenced by connectionist and functional models of linguistic and cognitive processing (e.g. Bates, Thal, & MacWhinney, 1991), by a growing awareness of the role played in pragmatics by cognitive capacities such as inference, theory of mind and executive function (Martin & McDonald, 2003), and by approaches such as Conversation Analysis (e.g. Damico, Oelschlaeger, & Simmons-Mackie, 1999) which focus on those features of pragmatics which can only be accounted for in terms of interpersonal, collaborative activity. All of these interactional approaches share a view of pragmatic impairment as ‘emergent’, or ‘epiphenomenal’ (Perkins, 1998), rather than as a stand-alone, monadic entity

Pragmatic disorders and their social impact

Pragmatic disorders in children and adults have been the focus of clinical investigations for approximately 40 years. In that time, clinicians and researchers have established a diverse range of pragmatic phenomena that are disrupted in these disorders. Pragmatic deficits include problems with the use and understanding of speech acts, the processing of non-literal language, failure to adhere to Gricean maxims in conversation and discourse deficits. These deficits are found in several clinical populations including individuals with autistic spectrum disorders, schizophrenia, traumatic brain injury and right-hemisphere damage. However, what is less often investigated is the social impact of pragmatic disorders on the children and adults who are affected by them. In this paper, I examine what is known about pragmatic disorders in these clinical groups. I then consider the wider social consequences of these disorders, where consequences are broadly construed to include factors that act as indicators of social adjustment
