A New Universal-Environment Adaptive Multi-processor Scheduler for Autonomous Cyber-Physical System
2012
International audience; Robot, spaceship and other applications that can be called autonomous Cyber-Physical Systems (CPS) are all smart embedded systems, which usually run in open environment by themselves with inhered intelligent capabilities. Besides the application intelligence, the researches of adaptive platform for such systems have also become topics recently. Based on the analysis of current work, a new environment adaptive scheduler (¦Á-S) for multiprocessor platform of a cyber-physical system is proposed in this article. And then, its related structures, models, and reasoning methods are studied deeply. Different from the existing ones, ¦Á-S can schedule all tasks according to th…
How to Enrich Description Logics with Fuzziness
2017
International audience; The paper describes the relation between fuzzy and non-fuzzy description logics. It gives an overview about current research in these areas and describes the difference between tasks for description logics and fuzzy logics. The paper also deals with the transformation properties of description logics to fuzzy logics and backwards. While the process of transformation from a description logic to a fuzzy logic is a trivial inclusion, the other way of reducing information from fuzzy logic to description logic is a difficult task, that will be topic of future work.
An Introduction to Ontology Based Structured Knowledge Base System: Knowledge Acquisition Module
2013
The following text presents the method of supplementing and verifying information stored in a framework system of the semantic knowledge base. The indicated method refers to the knowledge of ontological character, in other words to information about definitions of concepts and relationships among them. The aim of the method is the constant supplementing and verifying of the knowledge, and making more precise and detailed information about existing connections between concepts. The key aspect of the method is questions generating strictly dependent on the preconceived structure of stored knowledge.
Conceptual Ontological Object Knowledge Base and Language
2008
This paper deals with AI in aspect of knowledge acquisition and ontology base structure. The core of the system was designed in an object model to optimize it for further processing. Direct concept linking was used to assure fast semantic network processing. Predefined attributes used in the core minimize the number of basic connections within the ontology and help in inference. The system is assumed to generate questions and to specify the knowledge. The AI system defined in this way opens a possibility for better understanding of such basic human mind mechanisms as learning or analyzing.
A Knowledge-Based System for the Diagnosis of Alzheimer’s Disease
2003
Therapies to slow down the progression of Alzheimer’s disease are most effective when applied in its initial stages. Therefore it is important to develop methods to diagnose the disease as early as possible. It is also desirable to establish standards which can be used generally by physicians who may not be experts in diagnosis of the disease. One possible method to obtain an early diagnosis is the evaluation of the glucose metabolism of the brain. In this paper we present a prototype of an expert system that automatically diagnoses Alzheimer’s disease on the basis of positron emission tomography images displaying the metabolic activity in the brain.
Ontology-based standardization on knowledge exchange in social knowledge management environments
2012
After the hype around Web 2.0, organizations have revisited their efforts on knowledge management in order to create beneficial effects from their employees' activities in social environments. While there is not much doubt about the positive effects on creativity and flexibility, handling the variety of knowledge work environments that are in use at different organizational units or business partners can negatively affect productivity. While standards have generally mushroomed in the IT domain, there is a lack of standards in knowledge management. This paper argues for a standard on exchanging knowledge between social environments. We revisit related work, particularly standards which can b…
Introduction to the designing and deploying next generation knowledge systems and knowledge intensive business processes minitrack
2013
Work systems and the knowledge systems enabling them need to be aligned with emerging technologies to ensure organizational acceptance and to support effective organizational value creation. Traditional, often monolithic knowledge system architectures need to be redesigned due to technological progress manifested by, for example, social software, mashups, and semantic technologies. In our view, these redesigns lead to a new class of knowledge systems that we call “Next Generation Knowledge Systems.” Project management (PM) involved in the design and deployment of knowledge systems differs from the PM involved in traditional IS projects. While design projects are essential in creating next g…
Tieto, valta ja vastuu erityislasten hoidossa
2016
Artikkelissa tarkastelen sitä, kuinka erityislasten vanhempien tieto ja asiantuntemus lasta koskevissa asioissa rakentuu ja kuinka siihen suhtaudutaan auttamistyön tilanteissa. Aineistoni koostuu vanhempien kokemuskertomuksista, joissa he kuvaavat erityislapsen vanhemmuuteen kasvua sekä kohtaamisia ammattilaisten kanssa auttamistyön kentillä. Tutkimukseni rakentaa kuvan epäsymmetriselle vallalle perustuvasta vuorovaikutuksesta, jossa ammattilaisen ja asiakkaan roolia määrittelevät kulttuuriset kategoriat vaikuttavat vanhempien mahdollisuuksiin osallistua auttamistyön neuvotteluihin. Näiden kategorioiden mukaan asiakkaan roolina on olla tiedon ja avun vastaanottaja, minkä seurauksena heidän …
Ordered fuzzy rules generation based on incremental dataset
2021
This paper proposes a novel approach for building transparent knowledge-based systems by generating interpretable fuzzy rules that allow for present dependences between quantitative variables by accounting for uncertainty and the dynamics of their values. In the approach, IF-THEN rules are used to show the conditional relationship between the ordered fuzzy numbers, which contain additional information about the tendencies of variables' value changes. This paper elaborates an approach of mining ordered fuzzy rules from numerical data included in an incremental database. This approach develops the ability to record uncertainty and its change in the context of rapidly changing data. In additio…
Mobility of Cultures and Knowledge Management in Contemporary Europe
2012
In the aftermath of the fall of the Iron Curtain, the European Union (EU) has included more and more new member states from Central and Eastern parts of the European continent. This enlargement process has increased the cultural diversity of the European community as new languages and minority groups have been subsumed into the EU. It is the purpose of this article to discuss the challenges that result from the EU's enlargement, together with the added intra-European mobility of cultures, that affect the national knowledge infrastructures. Based on recent social scientific scholarship on mobility and cultures, this article proposes that knowledge management in contemporary Europe is not onl…
