Sensemaking on the Pragmatic Web: A Hypermedia Discourse Perspective
The complexity of the dilemmas we face on an organizational, societal and global scale forces us into sensemaking activity. We need tools for expressing and contesting perspectives flexible enough for real time use in meetings, structured enough to help manage longer term memory, and powerful enough to filter the complexity of extended deliberation and debate on an organizational or global scale. This has been the motivation for a programme of basic and applied action research into Hypermedia Discourse, which draws on research in hypertext, information visualization, argumentation, modelling, and meeting facilitation. This paper proposes that this strand of work shares a key principle behind the Pragmatic Web concept, namely, the need to take seriously diverse perspectives and the processes of meaning negotiation. Moreover, it is argued that the hypermedia discourse tools described instantiate this principle in practical tools which permit end-user control over modelling approaches in the absence of consensus

Challenges in Bridging Social Semantics and Formal Semantics on the Web
This paper describes several results of Wimmics, a research lab which names
stands for: web-instrumented man-machine interactions, communities, and
semantics. The approaches introduced here rely on graph-oriented knowledge
representation, reasoning and operationalization to model and support actors,
actions and interactions in web-based epistemic communities. The re-search
results are applied to support and foster interactions in online communities
and manage their resources
On the role of domain ontologies in the design of domain-specific visual modeling langages
Domain-Specific Visual Modeling Languages should provide notations and abstractions that suitably support problem solving in well-defined application domains. From their user’s perspective, the language’s modeling primitives must be intuitive and expressive enough in capturing all intended aspects of domain conceptualizations. Over the years formal and explicit representations of domain conceptualizations have been developed as domain ontologies. In this paper, we show how the design of these languages can benefit from conceptual tools developed by the ontology engineering community
Requirements modelling and formal analysis using graph operations
The increasing complexity of enterprise systems requires a more advanced
analysis of the representation of services expected than is currently possible.
Consequently, the specification stage, which could be facilitated by formal
verification, becomes very important to the system life-cycle. This paper presents
a formal modelling approach, which may be used in order to better represent
the reality of the system and to verify the awaited or existing system’s properties,
taking into account the environmental characteristics. For that, we firstly propose
a formalization process based upon properties specification, and secondly we
use Conceptual Graphs operations to develop reasoning mechanisms of verifying
requirements statements. The graphic visualization of these reasoning enables us
to correctly capture the system specifications by making it easier to determine if
desired properties hold. It is applied to the field of Enterprise modelling
A formal support to business and architectural design for service-oriented systems
Architectural Design Rewriting (ADR) is an approach for the design of software architectures developed within Sensoria by reconciling graph transformation and process calculi techniques. The key feature that makes ADR a suitable and expressive framework is the algebraic handling of structured graphs, which improves the support for specification, analysis and verification of service-oriented architectures and applications. We show how ADR is used as a formal ground for high-level modelling languages and approaches developed within Sensoria
Processing Metonymy: a Domain-Model Heuristic Graph Traversal Approach
We address here the treatment of metonymic expressions from a knowledge
representation perspective, that is, in the context of a text understanding
system which aims to build a conceptual representation from texts according to
a domain model expressed in a knowledge representation formalism.
We focus in this paper on the part of the semantic analyser which deals with
semantic composition. We explain how we use the domain model to handle metonymy
dynamically, and more generally, to underlie semantic composition, using the
knowledge descriptions attached to each concept of our ontology as a kind of
concept-level, multiple-role qualia structure.
We rely for this on a heuristic path search algorithm that exploits the
graphic aspects of the conceptual graphs formalism. The methods described have
been implemented and applied on French texts in the medical domain.Comment: 6 pages, LaTeX, one encapsulated PostScript figure, uses colap.sty

The pragmatics of specialized communication
El presente artículo pretende poner de manifiesto la importancia de la
pragmática en relación con la comunicación especializada. La estructura, el
contenido y la terminología de los textos especializados se ven afectados por
factores como la propia situación comunicativa y el conocimiento, intenciones,
expectativas y creencias previos del emisor del texto. La transmisión de tal
significado es difícil incluso en una sola lengua. Cuando la transmisión se
produce entre dos lenguas, como es el caso de cualquier acto de traducción, las
dificultades se multiplican. Por esta razón, es fundamental que los traductores
sean conscientes de cómo la pragmática, más que ningún otro componente del
lenguaje, puede afectar de forma decisiva a su actividad profesional
