Representational autonomy is a key property of an artificial agent. The type of representational structures and the role they play in the preservation of an agent’s autonomy are pointed out. The limitations of the traditional cognitivist approach and of the embodied intelligent approach to support such representational structures are described and indicated. A framework of self-organising Peirc...

Here we propose a scenario to simulate sign processing in virtual creatures inhabiting a world of predatory events. In order to infer the minimum organizational constraints for the design of our creatures, we examined the well-studied case of semiosis in East African vervet monkeys (Cercopithecus aethiops) and its possible neuroanatomical substrates. This approach allowed us to simulate a case ...

It is being increasingly recognized that the Saussurean dictum of “the arbitrariness of the linguistic sign” is in conflict with the pervasiveness of the phenomenon commonly known as “sound symbolism”. After first presenting a historical overview of the debate, however, we conclude that both positions have been exaggerated, and that an adequate explanation of sound symbolism is still lacking. H...

This paper will briefly present a semiotic approach to instrument interfaces based on a conceptual analysis of displayand control-components and their compositional semantics. Displayand control-components can be considered as prototypical objects that are themselves constructed from combinations of more elementary signs expressed in some combination of media. Different types of signs (or “repr...

1. INTRODUCTION Modelling activities are central in the development and maintenance of computerised information systems. Examples of types of models that are developed are: – The existing information systems in the organisation as they are perceived by the participants of the project are modelled during analysis. – The future information system (IS) is modelled during requirement specification....

Product ontologies provide consensual definitions of concepts and inter-relationships between them in a product domain of interest. They aim at solving integration problems in product-related information systems such as e-commerce applications. Assessing to which extent they actually meet user requirements remains a critical question for both ontology engineers and ontology adopters. Current re...

Search mechanisms in Social Network Services (SNSs) should take into account the meanings created, shared, and used by people through the use of the system. This paper investigates a new approach to develop search mechanisms more adequate for SNSs. SNSs represent an opportunity for people access to information in the Web. These systems allow individuals to constitute communities of common inter...
