A diffusion model account of normal and impaired readers.

2004

Acquired aphasics and dyslexics with even very profound word reading impairments have been shown to perform relatively well on the lexical decision task (e.g., Buchanan, Hildebrandt, & MacKinnon, 1999), but direct contrasts with unimpaired participants data is often complicated by extremely long reaction times for patient data. The dissociation between lexical decision and word naming performance shown by these patients is of theoretical importance, and here we present an analysis of processing underlying the lexical decision task. We are able to determine what aspects of performance are affected by acquired aphasics in the lexical decision task. We fit lexical decision data from aphasic pa…

Letter Position Coding Across Modalities: The Case of Braille Readers

2012

BackgroundThe question of how the brain encodes letter position in written words has attracted increasing attention in recent years. A number of models have recently been proposed to accommodate the fact that transposed-letter stimuli like jugde or caniso are perceptually very close to their base words.MethodologyHere we examined how letter position coding is attained in the tactile modality via Braille reading. The idea is that Braille word recognition may provide more serial processing than the visual modality, and this may produce differences in the input coding schemes employed to encode letters in written words. To that end, we conducted a lexical decision experiment with adult Braille…

Semantics for Managing Systems in Heterogeneous and Distributed Environment

2002

The problem of legacy systems collaboration is being solved. Particularly we look at the collaboration as workflow in a distributed and heterogeneous environment. Attention is paid to the description of semantics for workflow process definition languages. There are many solutions how semantics can be decomposed into logical fragments, but the problem of obtaining reusable components that are easy to compile into desired specific semantics still remains. We evolve the division of semantics by semantic aspects whose description is based on abstract data types (pre-built components) and connectors (meta-programs to produce the glue code) between them. This paper offers a way in which semantic …

SIGA3D: Semantic Combination of IFC and GIS to support Urban Facilities Management

2011

The interoperability of Information Systems has been a research topic for over thirty years. While some forms of heterogeneity have been settled by the adoption of standards, some domains, such as the Urban Information Modeling (UIM), require specific research. The UIM combines information from the domain of Building Information Modeling (BIM) with Geographic Information System (GIS) within a collaborative platform. Using this platform, a set of heterogeneous actors takes part in the lifecycle of the urban environment through a 3D digital model. This ambition is faced with several gaps such as resolution of semantic heterogeneity in the lifecycle management system, the resolution of structu…

On some conceptualizations of Europe in press discourse: an approach from access semantics

2016

This paper is concerned with the semantic potential of the lexical item . Its aim is to analyze and classify different conceptualizations of the lexical item as manifested in a corpus of headlines retrieved from the . Specifically, the study is based on 217 headlines derived from a corpus of approximately one million words of news items retrieved from the from May 2004 through December 2009. The analysis is grounded in the LCCM Theory, a theory of lexical representation and semantic composition developed by Evans (for example, Evans 2006, 2009).

Word Embeddings for Wine Recommender Systems Using Vocabularies of Experts and Consumers

2018

International audience; This vision paper proposes an approach to use the most advanced word embeddings techniques to bridge the gap between the discourses of experts and non-experts and more specifically the terminologies used by the two communities. Word embeddings makes it possible to find equivalent terms between experts and non-experts, by approach the similarity between words or by revealing hidden semantic relations. Thus, these controlled vocabularies with these new semantic enrichments are exploited in a hybrid recommendation system incorporating content-based ontology and keyword-based ontology to obtain relevant wines recommendations regardless of the level of expertise of the en…

Language-Game: Calculus or Pragmatic Act?

2013

We have tried to make the potentiality inherent in the concept of the linguistic game evident by taking it back to its original context in the work of Wittgenstein. This paper aims to re-examine some features of Wittgenstein’s thought, considering in particular the notion of ‘language-game’. We believe that the language-game might play a role in overcoming once and for all the classic distinction between semantics and pragmatics. We deal with the exegetical discussion of the notion ‘language-game’ as it was interpreted in two different senses: as a synonym of calculus or as a minimal unit of linguistic activity that is directed to obtaining certain pragmatic effects in a societal context. T…

Polysemy in Controlled Natural Language Texts

2015

Computational semantics and logic-based controlled natural languages (CNL) do not address systematically the word sense disambiguation problem of content words, i.e., they tend to interpret only some functional words that are crucial for construction of discourse representation structures. We show that micro-ontologies and multi-word units allow integration of the rich and polysemous multi-domain background knowledge into CNL thus providing interpretation for the content words. The proposed approach is demonstrated by extending the Attempto Controlled English (ACE) with polysemous and procedural constructs resulting in a more natural CNL named PAO covering narrative multi-domain texts.

Semantics of UML 2.0 Activity Diagram for Business Modeling by Means of Virtual Machine

2005

The paper proposes a more formalized definition of UML 2.0 Activity Diagram semantics. A subset of activity diagram constructs relevant for business process modeling is considered. The semantics definition is based on the original token flow methodology, but a more constructive approach is used. The Activity Diagram Virtual machine is defined by means of a metamodel, with operations defined by a mix of pseudocode and OCL pre- and postconditions. A formal procedure is described which builds the virtual machine for any activity diagram. The relatively complicated original token movement rules in control nodes and edges are combined into paths from an action to action. A new approach is the us…
