Clancey (1992) proposed the model-construction framework as a way to explain the reasoning of knowledge-based systems (KBSs), based on his realization that all KBSs construct implicit or explicit situation-specific models (SSMs). An SSM is a rational argument that explains the solution produced for a specific problem situation pertaining to a target application task (e.g., SSMs constructed for ...

This paper describes ongoing research in order to enhance our Domain Knowledge Manager (DKM) that is a module of a multi-propose Spoken Dialogue System (SDS) architecture. The application domain is materialized as an arbitrary set of devices, such as household appliances, providing useful tasks to the SDS users. Our main contribution is a DKM advisor service, which suggests the best task-device...

We present DKM, a distributed key management system. DKM implements a new data protection API. It manages cryptographic keys and policies on behalf of groups of users that share the data. To ensure long-term protection, DKM supports cryptographic agility: algorithms, keys, and policies can evolve for protecting fresh data while preserving access to old data. DKM is written in C# and currently u...

Knowledge management has inspired a shift from a transaction to a distributed knowledge management (DKM) perspective on interorganizational information processing. The DKM concept structures the knowledge creation, knowledge sharing and knowledge exploitation in organizations according to a product state model (PSM) required for management of technological diversity. Each player in the network ...

The paper addresses the electronic commerce application field of Health Care Administration. Models for knowledge distribution is a rare commodity in the Health Care Administration. Distributed Knowledge Management (DKM) is a concept that originated as an abstraction of a business model prepared for theion of a business model prepared for the mechanical and agricultural industry but holds promi...

Abstract— An educational platform is presented here for the beginner students in the Simulation and Artificial Intelligence sciences. It provides with a start point of building and simulation of the manipulators, especially of 2R planar Robot. It also displays a method to replace the inverse kinematic model (IKM) of the Robot with a simpler one, by using a Multi-Layer Perceptron Neural Network ...

We present a novel stereo imaging technique called dualfocus stereo imaging or DFSI. DFSI uses a pair of images captured from different viewpoints and at different foci, but with identical wide aperture size. Each image in an DFSI pair exhibits different defocus blur, and the two images form a defocused stereo pair. To model defocus blur, we introduce a defocus kernel map (DKM) that computes th...

We report results of an acoustic duration reproduction task with stimulus duration of 2, 4, and 6 s, using 45 emotionally negative, positive, and neutral sounds from the International Affective Digitized Sounds System, in a sample of 31 young healthy participants. To investigate the influence of induced emotions on perceived duration, the effects of emotional modulation were quantified in two w...

In our work a new approach, the Distributed Knowledge Management (DKM) approach, is used and organizations are seen as constellations of communities, which “own” local knowledge and exchange it through meaning negotiation coordination processes. In order to reify communities within a DKM system, the concept of Knowledge Node (KN) is used and then applied in a case study: a complex Italian natio...

We present a model of the internal representation and reproduction of temporal durations, the 'dual klepsydra' model (DKM). Unlike most contemporary models operating on a 'pacemaker-counter' scheme, the DKM does not assume an oscillatory process as the internal time-base. It is based on irreversible, dissipative processes in inflow/outflow systems (leaky klepsydrae), whose states are continuous...
