A Hybrid Neural Network Architecture for Dynamic Scene Understanding

1997

A hyprdid (neural and symbolic) architecture allowing for a deep understanding of moving scenes is described. The architecture is based on a working and effective integration among three levels of representation of data coming out from external sensors.

Towards Improved Representation and Communication of Pharmaceutical Expert Information

2002

The main concern of healthcare management has ever been embodied by two conflicting goals. These are improving care quality while reducing care costs. Information technology already has proven its positive impact on both goals. While general administrative tasks are being performed more efficiently for some decades, expert-oriented systems are entering the medical domain with increasing support capabilities for domain-specific therapeutic procedures, leading to more secure and efficient therapy planning, monitoring and control.

Hysteresis Model of Unconscious-Conscious Interconnection: Exploring Dynamics on m-Adic Trees

2015

The theoretical model outlined in this paper, has been experimentally validated by: H. Kim ,J-Y. Moon ,G.A. Mashour & U. Lee, ''Mechanisms of hysteresis in human brain networks during transitions of consciousness and unconsciousness: Theoretical principles and empirical evidence'', PLOS-Computational Biology, August 30, 2018, https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1006424; International audience; In this brief note, we focus attention on a possible implementation of a basic hysteretic pattern (the Preisach one), suitably generalized, into a formal model of unconscious-conscious interconnection and based on representation of mental entities by m-adic numbers. …

Knowledge Representation on the Web Revisited: The Case for Prototypes

2016

Recently, RDF and OWL have become the most common knowledge representation languages in use on the Web, propelled by the recommendation of the W3C. In this paper we examine an alternative way to represent knowledge based on Prototypes. This Prototype-based representation has different properties, which we argue to be more suitable for data sharing and reuse on the Web. Prototypes avoid the distinction between classes and instances and provide a means for object-based data sharing and reuse.

<title>HAP: a hybrid system for reasoning about actions and plans in robotics</title>

1990

The paper describes the main ideas and principles of HAP (Hybrid representation of Actions and Plans), a system for hybrid representation and reasoning in advanced robotics. In this context, hybrid representation refers to the integration of both symbolic and analogic knowledge representation paradigms. In particular, the logic/symbolic component is based on a KL-ONE-like representation language. The system embeds "analogic experts", that are concurrent procedures operating in a direct and fast way on the world representation. These "experts" help the system in planning a correct temporal sequence of actions. As a reference scenario, assembly (and disassembly) problems are considered. The a…

Reasoning with Multilevel Contexts in Semantic Metanetworks

2000

It is generally accepted that knowledge has a contextual component. Acquisition, representation, and exploitation of knowledge in context would have a major contribution in knowledge representation, knowledge acquisition, and explanation, as Brezillon and Abu-Hakima supposed in [Brezillon and Abu-Hakima, 1995]. Among the advantages of the use of contexts in knowledge representation and reasoning Akman and Surav [Akman and Surav, 1996] mentioned the following: economy of representation, more competent reasoning, allowance for inconsistent knowledge bases, resolving of lexical ambiguity and flexible entailment. Brezillon and Cases noticed however in [Brezillon and Cases, 1995] that knowledge-…

Abstract Syntax as Interlingua: Scaling Up the Grammatical Framework from Controlled Languages to Robust Pipelines

2020

Abstract syntax is an interlingual representation used in compilers. Grammatical Framework (GF) applies the abstract syntax idea to natural languages. The development of GF started in 1998, first as a tool for controlled language implementations, where it has gained an established position in both academic and commercial projects. GF provides grammar resources for over 40 languages, enabling accurate generation and translation, as well as grammar engineering tools and components for mobile and Web applications. On the research side, the focus in the last ten years has been on scaling up GF to wide-coverage language processing. The concept of abstract syntax offers a unified view on many oth…

Understanding dynamic scenes

2000

We propose a framework for the representation of visual knowledge in a robotic agent, with special attention to the understanding of dynamic scenes. According to our approach, understanding involves the generation of a high level, declarative description of the perceived world. Developing such a description requires both bottom-up, data driven processes that associate symbolic knowledge representation structures with the data coming out of a vision system, and top-down processes in which high level, symbolic information is in its turn employed to drive and further refine the interpretation of a scene. On the one hand, the computer vision community approached this problem in terms of 2D/3D s…

Dodatno svjedočanstvo. Fotografije u prozi Daše Drndić

2020

In this paper I will reflect on the role of photographs in the works of Daša Drndić. Mixing fictional and documentary modes is a characteristic feature of her texts. It is achieved among others by utilizing visual representations of the past. In my paper I aim to outline the strategies of visualization applied by the authoress (especially the traumatic, Holocaust-related experience), which materialize through photographs included in her works of literature. In the case of Drndić the visuals include for instance contemporary or archival photographs of places marked by the Holocaust and of Jewish inhabitants of Vienna as well as portraits of war criminals. Generally speaking, in her texts the…
