The ever-growing amount of documents (electronic or other) has increased the value of abstracts, and abstracting systems and services, as instruments for concentrating and supplying relevant information. Ongoing research in different disciplines, with abstracting as the common subject matter, points to the usefulness of the paradigm concept. This perspective would provide the coherence necessar...

We present in this paper our reflections about the requirements of new architectures and languages for the Web, confronted with the ones emerging from qualified scientists such as Mc Carthy [1] and Wegner [2]. The contribution highlights if and how these reflections may be concretely realized by means of extensions of non standard models and tools that we have already experimented and that appe...

We present a formal-model of awareness-systems founded upon the focus and nimbus model of Benford et al [2] and of Rodden [19]. The model aims to provide a conceptual tool for reasoning about this class of systems. Our model introduces the notions of aspects, attributes and resources in order to expose the communicational aspects of awareness-systems. We show how the system enables reasoning ab...

We report results of lexical accommodation studies involving three different interpretation settings: human-human monolingual; human-interpreted bilingual; and machine-interpreted bilingual. We found significant accommodation in all three conversational settings, with the highest rate in the human-interpreted setting. There is evidence for longrange mutual accommodation in that setting, as comp...

Communication is a transaction in which man invents and assigns meanings to achieve its objectives. In this context, psychological theories of communication emphasize different components of human communication, including attitudes, intentions and conditions required for effective communication. In psychological models of communication, the source is influenced by its communicational abilities,...

Medication errors can cause substantial harm to patients. Automated patient medication systems with RFID technology is purposely used to reduce the medication error, to improve the patient safety, to provide personalized patient medication and identification and also to provide counterfeit protection to the patients. In order to enhance medication safety for patients we propose a new dynamic ID...

This paper proposes a new scheme for partially blind signature based on the difficulty in solving the discrete logarithm problem. Under the assumption of the generic model, random oracle model, and intractable ROS-problem, this paper formally proves that the proposed scheme is secure against one-more signature forgery under the adaptively parallel attack. Previous schemes using two signing equa...

The Cyberspace Visualization Project – CVP – explores techniques for interactive 3D visualizations of the web, supporting orientation and basic communicational features1. Users can represent themselves within these visualizations and thus become aware of each other. This could be a base for a more direct communication on the web. Current software components are introduced and a placement algori...
